Vitamin D Expert: The Fastest Way To Dementia & The Big Lie About Sunlight!

He was literally two days away from. dying. So, this is a story where a. 15-year-old boy was diagnosed with blood. cancer, but he developed a flesh-eating. infection in his lung. He wasn't going. to make it. So, he has one request. He. wants to go outside, and that's exactly. what they do. And this was actually. mind-blowing to me. After the second. day, the infection is probably 60-70%. gone, and it became clear to me that. sunlight has so many important benefits. For instance, if you're the bed closer. to the window, you get discharged from. the hospital faster. So, I want you to.

give me any any information you have as. it relates to light health. For example, do you recommend these kinds of things? Dr. Roger Seholt is a board-certified. critical care physician who breaks down. complex science into clear, life-saving. advice. I see people at the very end of. their lives, so I know what prevents. them from getting this ill and how to. extend life. So, let's distill it down. into eight pillars. The first thing that. exercise, it reduces stroke, it reduces. depression. Next, sunlight. Did you know. that infrared lights from the sun is.

able to penetrate up to about 8 mm and. stimulate and upregulate melatonin, which prevent a lot of diseases like. dementia, cardiovascular disease, diabetes. >> What if you live in a cloudy country? >> There's some very actionable things that. you can do, and we'll talk about that. Next one, water. For instance, people. who use sauna are more likely to have. less death from cardiovascular disease. Next, air. There are studies that show. that just going out one day a week can. elevate our immune system and make us. more relaxed. And then there's.

But finally, trust. This is something. that can't be ignored because studies. have shown that people who have a good. faith and trust in a God are good. I see messages all the time in the. comment section that some of you didn't. realize you didn't subscribe. So, if you. could do me a favor and double-check if. you're a subscriber to this channel, that would be tremendously appreciated. It's the simple, it's the free thing. that anybody that watches this show. frequently can do to help us here to. keep everything going in this show in. the trajectory it's on. So, please do. double check if you subscribed and uh.

thank you so much because in a strange. way you are you're part of our history. and you're on this journey with us and I. appreciate you for that. So, yeah, thank. you. Dr. Roger Schwelt. With the work that you do, what is it. that you're aiming to accomplish? Outside of my clinical duties, uh and. maybe even part of that, I would like to. clearly. explain. very easily graspable tools that can be.

implemented to make people live their. best life and it's specifically in terms. of their health and their well-being. And as we dig down into health and. well-being cuz that's quite a broad. Yeah. >> basket, what is it within health and. well-being that you've spent your. career, your life focusing on? So, I'm a. board-certified internal medicine. specialist. Then I did an extra 3 years. of training uh here in the United States. on pulmonary and critical care. So, I. deal with all of the issues that are. related to the lungs and the critical. care aspect. So, if you are uh.

if you were admitted to a hospital and. you're critically ill, you'd go to the. intensive care unit. I'm the doctor that. you see. So, I'm putting in, you know, the lines, putting them on vasopressors, intubating them. Uh I worked in the. clinic this morning. And what are some of the unappreciated. things that most people don't think of. cuz we think of, you know, don't eat. processed food and exercise. But, is. there things outside of that that you. don't think the average person. appreciates enough? Yes, absolutely. What are those things? So, if we look at. those things that extend life.

and are beneficial, we could put them. into what I call eight pillars of. health. If you can imagine your life is. uh a chain with a bunch of links, okay? And I'm talking medically. Each one of those links is an organ. system. So, your heart is a link. Your lungs are. a link. Your liver is a link. Your. kidneys, etc., etc. As you go through life, imagine those. links starting to erode. So that at some point in your life,

you're going to get some sort of a. disease or a diagnosis that focuses on. one organ system of your life. For many. here in the United States and in the UK, it's the heart. And as that link gets more eroded, we can see very clearly that this is. going to be the link that's going to. break first. And therefore attention is. paid to that link. For many, that. diagnosis comes with medications. So. here here is where the first truism that. I would say going forward, all. medications have side effects.

And what the aim is to do in modern. medicine is to utilize the knowledge of. those medicines and their effect on the. human body so that we leverage the other. links to protect that weakest link. So I. could go through a whole bunch of. medications that I give all the time to. patients in the intensive care unit, where I'm focused on saving their life. because I can clearly see which link is. the weakest, but I'm doing it knowing that there's. side effects because I'm trying to save. that link to save that life. And I'm.

leveraging those other things. For. instance, somebody comes in with a stroke. And. they have they've they've lost weakness. on the on the right side of their body. or on the left side, whichever side. I can give them a medication. immediately that will break up all of. the clots in their body. It's called TPA. or TNK. And it will restore blood flow. to the brain and it will reverse many of. their symptoms. If they come in soon. enough, we can do this.

What's What's amazing is that that. medication has an effect that can do. that, but it also has a pretty. significant side effect in that it could. break up clots somewhere else and cause. bleeding. So we have to be careful about what it. is that we're doing. Clearly there, what we're doing is we're. saving one link at the expense of other. links, but that's what you have to do in. an emergency situation. But if after. that, I simply send that patient home. without telling them why they had that. stroke and what they need to do to.

prevent themselves from getting that. stroke again, and what are the lifestyle. factors that caused that to happen, I haven't done my job. So, what is what. are the interventions that we can do. hopefully early on in life. so that we don't have those links. eroding, so that all of the links are. strong, and as we get older, we can. continue to strengthen all of the links. Here are the eight. So, nutrition. That's That's nutrition. Basically, you. know, we know there are studies that. have done that showed that that. depending on what we put into our bodies.

as food can have a dramatic impact in. terms of our well-being. Okay? So, that's nutrition. Exercise. As I was saying, exercise not only I. mean, drugs and things have side. effects. Exercise have side benefits. So, exercise obviously is going to make. you more fit. It's going to make you. have better endurance. But did you know that it reduces stroke? Did you know that it improves. uh well-being? It reduces depression. There's so many benefits. So, all of. these links are actually improving. There's no leveraging here.

Exercise is incredible. Water. So, this may sound obvious, right? Like. you drink because you're thirsty. Where. I would like to go today is to talk a. little bit about what the effect of. water externally on your body can do. And you're talking there about like hot. and cold. >> Exactly. usage. Exactly. >> or cold plunges, saunas, that kind of. thing? >> Exactly. Okay. And we'll get into the. actual evidence for this. We'll get into. it later, but what is the potential. >> system. Which changes your probability of. diseases and stuff like that. >> Correct. Absolutely. Especially in the.

acute setting. Especially. So, not only. in the acute setting, but we also have. pretty good data from Finland, where. they have more saunas than almost than. people, uh where they've actually done the. research and and shown with dose. response curves that this is actually. very beneficial. We won't get into too. much of that, but what I want to focus a. little bit more on because of my job in. the intensive care unit. and what we're seeing right now with. viruses and mutations and the innate. immune system, why something like this. may actually be very important, uh, as.

we look forward. Interestingly, as we. look forward to future famous pandemics, we can look backward and see what we had. done in the past. And we've got some. really actually really good information. on that. Let's go to. sunlight. This is something that, um, I've really become more and more. involved with because of some of the. benefits that that this can do. A very big misconception that people. have is that sunlight equals vitamin D. And therefore, if you take a vitamin D. supplement, you don't need to go in the.

sun. This is really something that's uh, now, um, being debunked. Sunlight has far more. benefits than just vitamin D. Not saying. that vitamin D is is not something that. you want to supplement with. I. supplement with vitamin D. I think it's. there's a benefit to supplementing with. vitamin D, no question. But sunlight has. so many important things and I and I. really would like to spend the bulk or. the lion's share of the time talking. about this because this is really. important. Okay.

Um, this is a this is this is amazing. Uh, and it really made me think about. sunlight. So, this is a story. by a lady by the name of Amy Hanmeyer. Her 15-year-old boy. was diagnosed with lymphoblastic. leukemia, went into uh, the hospital, actually started chemotherapy for it. Which is blood cancer. >> It's a blood cancer, yeah. And so, this. the treatment for blood cancer is. chemotherapy, which he started. The side. effect of chemotherapy is suppressing.

the immune system. And unfortunately, he didn't realize it, but he developed uh, he didn't realize. it immediately, but he developed a a. fungus flesh-eating infection in his. lung. And went into the hospital in June of. 2024. Uh this is in Minnesota, tertiary care. hospital. And he. got worse and got worse and got worse to. the point where the only way that they. could control this infection was to. actually remove his left lung, which.

they did. So, this is a 15-year-old boy. He is without his left lung. He only has. a right lung. And he starts to decline even after. that. They do a CT scan and it shows. that now the infection has moved to the. his remaining right lung. They have a family conference. And as Amy is telling me this story, I. could hear her choking up. She's telling. me this on the phone. She's saying that he's 15, he's. completely awake, he's completely alert. He knows everything that's going on.

around him. He's on a ventilator like a. a machine that they use for for sleep. apnea. It's like a BiPAP machine that's. breathing for him. It's not intubation, but it's on his on his mouth. And the doctors, you know, have done. everything they possibly can and they. say, "Look, he's getting worse. We can't. take Obviously, we can't take the right. lung out. We can't put him on a. heart-lung machine because there's no. sort of destination to where he's. going.". Uh. we recommend not intubating him and. making him what they call DNR, do not.

resuscitate. So, they're like, "Wow." They were not. expecting this coming. So, they have a. big conference. Somebody they they call. in help to like, "How do you explain to. a 15-year-old boy that you're dying? And how how's that going to feel?". So, they asked the doctors, "How how. much time does he have?" They say, "2. days.". So, in this in this situation, they ask this boy, "Okay, you're going to die. What do you want to do with your life in.

the in the next 2 days? What do you want. to do? And surprisingly, he says, "I want to go. outside.". "I just want to go outside.". This this guy grew up probably on a farm. or something and he spent his time. outside. So, he wants to go outside. So, you know how. I mean, I don't know if you know this, but like if you're a nurse or you're a. doctor. and you've done everything you can and. this and you're just completely. horrified at the fact that this. 15-year-old is going to die and he has. one request, you're going to move heaven.

and earth. to fulfill that one request. And that's. exactly what they do. They. get this boy the hospital bed outside. He's on a BiPAP machine the respiratory. therapists have put together. So, this. guy is outside. And they're not putting him outside to. get better. He's just this is his dying wish. They. also use this thing called a Firefly. It's like a a light device that they. were using. I to I'll be honest, I don't. know which did it. The Firefly was the.

It's a It's a light device that gives. off light at different wavelengths and. they would use that for about three. times a day for 5 minutes. This guy. does not die. After the first day. his white count starts to come down. That's like a a measure of the infection. that's going on in the lung. And and and by the way, they do a CT. scan of his lung before this all starts. and the and it's just the the the. remaining lung on the right is just. filled with infection. It's horrible.

By the By the second day, the white. count comes down even more. And and by. the way, they haven't changed any of the. other treatment. He's been in By this. point, he's been in for 6 weeks. He has not seen the light of day. And and he's still getting the powerful. antifungal medication amphotericin B and. posaconazole. All of these things are. are really high-powered drugs that that. just completely fight fungus, but it's. not working. He's getting worse. But now, he's out for the second day. The white count's coming down, which is. good. That's a good sign.

His oxygen requirement is coming down. That's a good sign. He's requiring less. and less oxygen. By the time he gets to. day five, okay, we're already past two days. He's off the BiPAP. He's on regular. just nasal cannula oxygen that you see. people wearing on their nose. The doctors are scratching their head. They're like, we we should get a CT scan. to see what's going on. So So, Amy tells me that they they get a. CT scan of this guy, and they're in the. room. And some some even like swear. under their breath. Like they they're. completely.

amazed. Because on the CT scan, obviously the. left lung is still gone. But the right lung, the disease is probably 60 70% gone. And. he he's still alive. He goes home. There's no sign of the. disease after after treatment. And he he. uh I I just she just uh communicated. with me to tell me that he just got his. Make-A-Wish. uh thing for for his cancer. He's.

continuing treatment. And to And she just can't believe that. he was literally two day two days away. from dying. They changed nothing. They changed none. of his treatments. The only thing that. they did was they took him outside and. they they were using this Firefly before. inside, but they were using it more. consistently when he got outside. Maybe hospitals should be outside. >> This is exactly what. Okay, so if you wanted to know what my. drive was, what what it is my purpose. that I'm doing right now, I'm working at.

three different hospitals. And. I'm trying to work in each of those. three different hospitals to try to get. patients outside. The biggest barrier. that we have is staff taking those. patients outside. That's the thing. that's the hardest. But this is what we. used to do. Steven, this is what we used. When we built hospitals at the turn of. the century, we had hospital rooms where. beds could be taken out onto the veranda. and people could get sunlight. I would. love to see a time where we could go. back to that type of effect. There are. studies that have been done. People in a.

two-bed room, if you're the bed closer to the window, you get discharged from the hospital. faster, on average. Really? Yes. I need to swap sides of the bed with my. girlfriend. She's on the sunny side. >> There There's so much evidence for this. People who are in hospitals that are. have bigger windows, they give better. surveys. And hospitals. reimbursement is tied. to the surveys that they get from. patients. So, it's literally a.

win-win-win. If hospitals started to, I. believe, get patients outside. And And. they're already doing this. There. I don't want to say that this isn't. happening. There are hospitals that are. have programs to get patients outside. Um I think we just ought to be doing it. a lot more. Um. temperance. Temperance? What does that. mean? >> It's an old term, isn't it? It really. means. moderation. And And I I would say in. this sense, temperance really means to.

avoid toxins in the body. Um As somebody who is a pulmonologist, who is What's a pulmonologist? >> is someone who takes care of the lungs. And so, as a result of that, I see a lot. of issues with lung cancer. related to smoking. Um I see it in the intensive care unit, people with liver failure as result of. alcohol abuse. I also see people. on amphetamines. Here in Southern. California, where I reside and where I. work, we we have quite a bit of that.

And uh temperance, if if you want to. live a long and wholesome life, there. are some toxins that you want to avoid. And uh And And And understanding that is. really important. So, this is something. that, if you stop some of those things. that we're talking about, all of those. links are going to be improved. Air. Seems kind of obvious. Early on I used. to think that that what this meant was. getting pure air with absolutely nothing. in it except for just nitrogen and.

oxygen. That's not true anymore. We now understand that for you to have. the best type of air, it actually has to come with some things. in it. Just like our our gut has a. microflora that you may have heard. about, so too does the air that we. breathe also must have that. And the. best type of air that you can have is. actually outside. Rest. This is really interesting because we. just mentioned that exercise was a. pillar, but rest also is. How can rest.

and exercise at the same time be pillars. of health? And it really comes down to. knowing when to do what. Sleep, which is. also part of rest. So we're not just. talking about a daily rest when you go. to sleep. And and as a sleep physician I. can tell you quite a bit. We have lots. of information about how long we should. sleep, the quality of sleep, some of the. diseases that prevent us from sleeping. Sleep is so important. I can't I I. couldn't over express it enough. Not.

just a a daily rest, but I would also. say and and venture out we can talk more. about this, a weekly rest. A weekly. rest? >> A weekly rest. What do you mean weekend? Yeah. Yeah, absolutely. How many times do we even on. the weekend do we put down our our. phone? Never. Or we stop reading emails. And we take the time out to do things. that we would never be able to do. Finally, trust. So this is something that really just.

can't be ignored. And and I'll say this. up front that um. in the world of research and science. there is a there is a silo of science. and there is a silo of faith. But, what's what we can't ignore is the. growing body of evidence. from the scientific world that's peeking. over and looking at faith, that people. who have faith and people who have faith. in God, uh whether that is uh their God in in.

that particular denomination, are better. apt and able to deal with stress and. depression and anxiety. So, this is something scientifically. that has been shown. Now, if you you may have noticed that I I did. these in a particular order. Um and if you go through them, you've. got nutrition, you've got exercise, you've got water, you've got sunlight, you've got. temperance, you have air, you have rest, and finally you have trust. You put that.

together and it spells out NEWSTART. So, interestingly, these these. particular topics are not copyrighted, but there is a um there is a university. in Northern California called Weimar. University that has actually put these. together in that very pattern as called. it NEWSTART. They actually have a. NEWSTART program. Um and so, this is something that uh. that is actually being used uh. internationally. So, of these subjects that you just went. through there for this NEWSTART um.

framework, where do you want to start? I think actually sunlight is is one of. those things where I'm excited about all. of those, but I think sunlight is. is really where we have It's the Let's. put it this way, it's the lowest-hanging. fruit. Okay. Explain to me why sunlight. is the the place where your focus is at. the moment. It's a long trip that has gotten me to. that. Um and I and I think part of it. has to has goes through right through. COVID. So, as a critical care intensivist, when.

I heard that there was this virus that. was coming, they all told us that it was. going to be people with respiratory. illnesses, which I was certainly. comfortable with. But, that's not what it turned out to. be. We certainly saw people with. respiratory illnesses, but what we saw. in the intensive care unit, the people. that were dying around me. were people with obesity, people with. heart disease, people with kidney. disease, people with dementia, people. with chronic diseases. And it made me think, why was that the.

case? All of those things. have one thing in common. And many other things, too. But, specifically, they're rooted in. something called mitochondrial. dysfunction. So, let me unpack that for. you. And and this has to do with longevity, this has to do with aging. This is a. huge topic that is now just emerging. And we're we're now finding more about. this. So, what when we were when I was. in high school biology, when I was in. college, uh we all learned about this.

little organelle in all of our cells, except for red blood cells, called the. mitochondria. And and and I have to say. it, what is the mitochondria? It's the. powerhouse of the cell, right? So, it's. the thing that makes energy. What we didn't know at the time is that. as we get older, the output from these. batteries in our cells drops by about. 70%. Damn. Can you imagine running your. house on 70% less energy? Well, how. fundamentally that would change what. change what happens in your house? Like, you could not run the laundry the same. way. You could not run the microwave and.

the laundry at the same time. >> And what does that look like in terms of. symptoms? Excellent question, because. what it looks like is depending on the. cell type that we're talking about, that's going to have the issue. So, if. we're talking about the liver, the. liver's going to get more fatty. If. we're talking about the heart, the. heart's going to is going to become more. congested. If we're talking about the. brain, it's going to have more dementia. And so, what's what's happening here is. that as we get older, the batteries in. our cells are not working the same way. as they used to. Metabolism is slowing. down. And and so, these are these are huge.

issues. And all of these diseases that I just. talked about, all the ones that we saw. in COVID, if you look in a lot of these. diseases, they are rooted in. mitochondrial dysfunction. So, the. question is is why is that the case and. what can we do about it? So, there was a paper that came out in. 2019. that fundamentally changed the way I saw. this. It was written by Russell Reiter. who is the. executive editor of melatonin research. It's a he's out of University of Texas.

And Scott Zimmerman who's a light. engineer. And what they set forth was to. show that basically. sunlight. is. made up of so many different types of. wavelengths. You've got ultraviolet on. one end which of course makes vitamin D. And it's very beneficial. It it it's the. type of light from the from the sun that. is very short wave. and but cannot penetrate very deeply. Let let me let me back up a little bit. and explain. You pull up to a stop sign and somebody.

pulls up next to you and they're playing. the latest hip-hop music. How does that. sound to you in your car? It's very boom boom, right? >> Yeah, muffled. It muffled. And the. reason why is because low wave frequency. has the ability to travel very far. Go to the Grand Canyon and there's a. thunderstorm at the other end of it. What do you hear? It's like a rumbling. And then as it gets closer, you hear the. higher pitched sounds. This is a. fundamental physics. principle. And so when the sun is is.

shining, there's very short wavelengths, ultraviolet B involved in vitamin D. But. at the other end, there's this infrared. light which we'll talk about or red. light. It's very long wavelength and it. can penetrate very very deeply. That's very important because what we're. talking about is the human body. And if. the sun is going to have an effect on. the human body, it's got to be more than. just the skin. So, that's exactly what what this paper. showed is that basically. infrared lights.

from the sun. is able to penetrate probably up to. about 8 cm according to Scott Zimmerman. in this article. And it fundamentally interacts with. specifically the mitochondria. And what does it do to the mitochondria? So let's let's back up and talk about. the mitochondria cuz this is central. The mitochondria to the cell is like the. engine in your car. The engine produces locomotion that. causes this the wheels to spin. But in. the process of doing it. it causes heat to surround the engine.

And if you don't deal with that heat. it will shut down the engine. It will. make it more inefficient and eventually. it will shut it down. So what do all. internal combustion engines have? They. have a cooling system. They have a. radiator. They have a an oil pan. They. have a water pump. And that's exactly. what the cell has to have for the. mitochondria. It's not heat in the. mitochondria. It's called oxidative. stress. And it's specifically oxidative. stress that causes destruction and. and yeah, destruction of the.

mitochondria and leads to these types of. diseases. So oxidative stress causes the. mitochondria not to work well. This. leads to diabetes. Oxidative stress. makes the mitochondria not work so well. This leads to dementia. So there's a. This has already been laid out. This is. not that controversial. The. controversial part is what do we do. about it? So what these guys in this. paper showed. was that and and not just them but look. reviewing the literature is that the. mitochondria makes its own cooling. system. And that cooling system is melatonin.

Now you might think be thinking, wait a. minute, melatonin, isn't that the isn't. that the stuff that we take that our. brain makes right before we go to sleep? Yeah, that you're it's absolutely. correct. That's what happens. The problem is is that this is not. melatonin that's made in the brain. This. is not melatonin that goes through the. blood supply and goes to It through our. blood and tells us it's time to go to. sleep. This is melatonin that's made in. the cell in the mitochondria. And it's a powerful antioxidant that. basically prevents the oxidative stress.

from occurring. What Scott Zimmerman and Russell Reiter. showed and and proposed in this was that. basically the infrared radiation that's. coming in. to the body is able to stimulate and. upregulate melatonin and a number of. other factors that keep the mitochondria. cool and can actually improve the energy. output of the mitochondria. So this is This was actually. mind-blowing to me and I'll tell you why. I resonated with this as a critical care.

physician because there was two things. that bothered me the most. Number one. SARS-CoV-2 virus. When it comes into the. body, it interacts with something called. the ACE2 receptor. You may have heard. about the ACE2 receptor. Okay. This is. where the the virus actually latches on. to the cell. and gets internalized. So what is this. ACE2 receptor? Is this Was this there. for all of humanity just to be a. receptor or does it actually have a. role? It turns out it actually has a role and. mind-blowingly.

the ACE2 receptor is involved in. mitigating oxidative stress. So in other words, it's another part of. the cell's cooling system for the. mitochondria. What. what's happening is that the. the virus when it attaches to the cell. is basically eliminating that action. And so. imagine you have a bunch of people with. various different engines running at. different temperatures. In other words, you've got some people with chronic.

disease and we know their engines are. running hot. We have some other people. who are completely healthy and they're. doing quite well. Their engines are nice. and cool. They have no problems at all. Now imagine COVID comes and SARS-CoV-2. is infecting everybody. What that tendency is to do is because. it's knocking out everybody's ACE2. receptor, which has the ability to cool. down the engine if in other words, it's. causing everybody's engine to run hot. Right? So, but in somebody So, in other. words, picture it this way. You're. You're You're driving along in your car.

and your thermometer is there and all of. a sudden there's this big hill that you. have to climb, called COVID-19. Who's. going to make it over that hill and. who's not going to make it over that. hill? The people that make it over the hill. are those with great cooling engines. that whose temperatures are running. great. The ones that don't make it over. that hill are the ones that have the. thermometer on their engine running hot. Those are the ones that poop out at the. top and can't make it and they're. they're the ones pulled over to the side. of the road with the hood up and the. steam coming out of the out of the. engine. Do you understand what I'm.

saying? >> yeah. So, this makes perfect sense to me. why I wasn't seeing what they were. predicting, which is respiratory. patients coming into the ICU. Who was I. seeing in the ICU? I was seeing people. with dementias, as we talked about, diabetes, kidney disease. These are the. ones that were that that were sick. The. other thing that that really hit me. and resonated with this. was and this was this was not even. controversial. We knew early on in the. pandemic that people who came into the. hospital and had higher levels of. vitamin D.

did really well. They didn't die. They They didn't have the same chances. of dying. People who had low vitamin D. levels, they had much higher levels. chances of dying. So, we would check these vitamin D. levels. And so, think about this. You're You're there at. ground zero and you're taking care of. these patients and you see this data. over and over and over again that. vitamin D is very predictive of who's. going to die. Obviously, what are you. going to do? Even though this is an.

associative study, that association. doesn't mean causation, you're going to. be giving people vitamin D. and try to get those levels up. The problem is is that we gave vitamin D. and it really didn't have much of an. effect. So, you gave it in supplement tablets. >> Yeah, when people would come into the. hospital exactly. Exactly, just like that. In fact, I was. supplementing myself. I mean, what have. you got to lose, right? I already took my vitamin D tablet this.

morning. I don't There's not There's. very hard to overdose, but it's. possible. So, you noticed that it was. hard to treat people with vitamin D, but. giving them a a tablet didn't really do. much. That's correct. Why? Well, this is what I believe is the is. the is the fact is we saw that people. with high levels of vitamin D or normal. levels of vitamin D did better than. those that had low levels. I believe. that that was a marker of something. else. In other words, people who had higher. levels of vitamin D meant.

that they were out in the sun more. They. were outside more. Than those the people that had very low. vitamin D levels. The people with low. vitamin D levels were telling me these. are people that were not getting outside. into the sun. And so, what's the real. factor here? What's doing the heavy. lifting? And I would propose and Scott. Zimmerman and Russell Reiter would. propose, and I can tell you a number of. other scientists that would agree with. me on this, is that infrared radiation. from the sun. is causing an effect at the.

mitochondrial level in terms of. oxidative stress. And that vitamin D was just the marker. of who was getting the infrared light. and who was not. Who was going outside. and who was not going outside. So, when. the sun is shining for the most part, you're getting infrared light. You're. getting the entire the entire biological. spectrum from the sun. We can go to the. longest wavelength, which is far. infrared, all the way to the shortest wavelength, which is ultraviolet B, okay, which.

makes vitamin D. So, in other words, when you are outside. in a natural environment, you're getting. a very broad spectrum of light. And so, because of that, if you're. getting infrared light, you're also. going to be making vitamin D. Yeah, you're getting both. Um. Now, that can change because in the. wintertime. when the sun is lower in the sky, especially, you know, in England, this. is this is a special issue at that. latitude. When the sun is low in the. sky, it's got the light has to penetrate.

through obliquely through the. atmosphere. And because of that, shortwave. radiation from the sun, like ultraviolet. B, does not make it very well. So, there's times of the year where you're. not getting enough ultraviolet B or. maybe even no ultraviolet B from the. sun. Which makes the vitamin D. Which. makes the vitamin D. And that you're. you're going to be deficient, you need. to supplement. However, during that same period of time. when you're not getting enough vitamin D. because there's no ultraviolet B. radiation, that sun is low, but that's.

it's still enough to allow that long. wavelength penetrating infrared light to. still come through. So, is the longwave. infrared light the type of thing that we. see. these gadgets doing? Absolutely. And and. I would say just to be specific is. because you can see that as red light. there, that's not infrared light because. you can see it. So, infrared light technically is. completely invisible. But this these do.

give out infrared light, but you just. can't see it. >> So, it's toward that red end of the. spectrum. And people like Glen Jeffery. out of UCL. is actually doing research at 670. nanometers of red light and has shown. in randomized controlled trials that. that type of light right there at 670, the type that you can even see, actually does improve mitochondrial. efficiency. He's shown this in a number. of randomized controlled trials. It. improves eyesight. And and you have to. realize that the retina at the back of. your eye is very rich in mitochondria.

He's shown this in terms of managing. glucose and and output for mitochondria. And and the reason why these things work. so well is because what's going on here. is as you get older, your skin starts to. become more saggy because the the. fibroblast or the cells in your skin, they're designed to make collagen and. collagen is the skeleton that makes your. skin soft and subtle. Yeah. Don't mind. me. Please carry. >> No, no. So this is this is exactly My.

wife uses the same thing. This is a fun. charge one day. >> So what what's going on right now is. that red light. which can penetrate very deeply down is. going into the skin and it is activating. the mitochondria in your fibroblast to. produce more energy which those cells. need to deposit collagen. And so when. you deposit collagen, that's going to. give the skin a more tight uh feel. because as you get older, that collagen. deposition is going to get less and less. and less. >> So this is going to help keep me looking. young. That's the whole point of it. And.

you're saying that the the light in. these penetrates what, 6 or 7 cm or is. it. >> does about 8 cm. Uh this red light would. be a little bit less because this. light obviously you can see it, so it is. a little bit shorter wavelength, but. yes, this light, the red light can. penetrate deeper than for instance. yellow light or blue light. And it's. this light particularly that interacts. with the mitochondria to increase that. So should we be putting this all over. our body because okay, it's good for my. skin, but if it's penetrating deeper, presumably those other parts of my body.

that would benefit from that, another. mitochondria. It's interesting you say. that. Um the the the study that I'm. referring to with Glenn Jeffery out of. University College London, he took uh. young people in this study. He gave them. a a bunch of glucose. And everybody who. gets a bunch of glucose should have a. spike in their blood sugar. And he randomized them on their backs. to see what would happen when he shined. red lights uh on their backs. And the. people that got the red light had lower.

spikes. In other words, it seemed as. though the mitochondria. were metabolizing faster, which caused. less of a spike of the glucose in their. blood. The way he confirmed that is. looking for the byproducts of the. mitochondrial metabolism, which is. carbon dioxide. So, when we breathe, when we metabolize, we're breathing out. carbon dioxide, which is the result of. of a mitochondrial metabolism. And in. fact, in those people that had the light. on, it showed a higher level of carbon.

dioxide in the exhaled breath. The whole. point of that is to get back to your. question is whether we should putting. this all over your body. He was able to. get that effect systemically with just. putting the light on the back. Um that was a that was a systemic. ability. What We don't understand. everything about the mitochondria, but. what we do seem to understand is that. they can communicate with each other. And that you don't need to have this all. over the body to have systemic effects. In this particular case though, if you. want to have the skin here to be more.

you know, younger-looking, then it makes. sense that this is where you need to. have it. If you want to have a. particular other part of your body to. look younger, then then perhaps that. that's where the light needs to go. So. interesting. So how long did it take in. those studies to see the effect of red. light therapy like this? Well, that's a. very good question. If you talk to Glenn. Jeffery, which I have, he noticed a an. improvement in 15 minutes. 15 15 minutes? What did he notice in 15. minutes? He said he has studied the.

mitochondria in fruit flies and in. mosquitoes and bees and in human beings. and it's the same every time. He says. after about 15 to 20 minutes of this. type of light in that type of setting, there is a switch. that turns on and it and you and you. don't need further stimulation. Further. stimulation doesn't do anything more. It's a it's a very bizarre thing. You. would think that the more light that you. gave, the more the effect would be. It's. not. After about 15 minutes, it it. there's something that changes in the.

mitochondria. There are certain theories about where. this might be. This might be in the. electron transport chain. complex four. Uh these are very. technical things. There's a lot of. studies that are actually There's a. number of groups that are actually. looking at this. Uh there's a whole area of science. called photobiomodulation, which is. looking at this. But, 15 minutes is. really what it takes. So, we're not. we're not talking about a long period of. time. This is really really interesting. So, getting back to my.

experience in the intensive care unit. The vitamin D wasn't working. These patients were dying, and it became. clear to me that COVID was a metabolic. issue. for these patients. By the time I had realized this, the sir I mean, the pandemic arguably is. still going on because people are still. becoming infected, but the rush to come. into the hospital and the and the number. of bodies that we were seeing. circulating through the intensive care. unit had dropped dramatically. And at that point, I was able to.

see that potentially. infrared lights may be very beneficial. in these patients with COVID-19. Now, there was a study in Brazil. They took. COVID patients. that were that were sick enough to be. admitted to the hospital, but not too. sick to be intubated in intensive care. unit. And they did something tremendous. They. actually manufactured a jacket that they. could put on patients. And on the inside.

of this jacket were these LED bulbs that. gave off. infrared radiation at exactly 940. nanometers. They put the jackets on, and they randomly randomized assign. which jacket was turned on and which. jacket was turned off. It was blinded. because the light coming from this. jacket could not be seen by the human. eye. It wasn't even enough to produce. enough heat. And so they they did this on 30 subjects. and they randomized them. 15 did it 50. 50 all 15 had or all 30 had the jackets.

on. 15 had it turned on, 15 did not have. it turned on. And they watched them. What happens to these patients? Every single endpoint that they looked. at was statistically significant. And What does that mean? >> It means that the differences between. these two groups could not have been. from chance. There was a real difference. The group that had the jacket turned on. had improvement in their oxygen. saturation. Had could take breaths in more deeply. and stronger. Had improvements in their.

blood white blood cells. Um and not only that, had improvements. in their heart rate, their respiratory. rate, all of these statistically. significant. But the most important and. mind-blowing statistic was the length of. stay in the hospital. So, they had these jackets on. for 15 minutes. once a day. for 7 days. In the group that did not have the. jacket turned on, their average length. of stay was 12 days in the hospital.

For those that had the jacket turned on, it was eight days. That was four day. difference. That's tremendous when you. realize that it costs thousands of. dollars. to hospitalize patients. It's it's a huge amount when you think. about the fact that there are certain. drugs that get FDA approved for. influenza for instance by just cutting. short the symptoms for 24 hours. This is. not just 24 hours for people were. discharged.

from the hospital four days faster. When. I saw that study, that was enough for me. to convince me. I mean obviously it was. 30 subjects, right? We should do a. bigger study. We should do a hundred a. couple hundred, right? That would be. that would be ideal to do. But the fact. that with just 30 patients they could. show statistical significance. That was. enough for me to say every patient from. now on that I see. that comes in with COVID-19 that's. hospitalized, that they're asking me to. go intubate, to bring to my ICU, these. patients are going to get outside. I don't have that jacket that they made.

in Brazil. I I I don't even know how I would make. that jacket. They made it for the study. And it's not commercially available. There's no 940 nanometer lights, which. is what they did in the study. But I do. know this. I do know that sunlight has. 940 nanometers in it. And if I could just take these patients. outside. maybe they could improve. So I had I got. my wish. I had a patient on the floor. He was on 35 liters a minute.

100% oxygen through high flow. Through. his nose. Through his nose. Barely. barely saturating because he had. COVID-19. And uh I was asked to go see him because. he was potentially needing to be. intubated or brought to the intensive. care unit. I could not believe it cuz I. had not seen one of these in months. So. I went down, walked into the room, opened the door. It was in isolation. I. had a mask on, the whole nine yards. The. room was completely dark. The blind was. closed. His daughter was there. And the. first words out of his mouth to me was. "Doc, how much time have I got?".

I mean, it was a catastrophe. Like. there's no light, no circadian rhythm. This guy was depressed. I immediately called my respiratory. therapist, immediately called the charge. nurse. We got everybody together. And I. said, "We need to get this guy outside.". It was a bright and sunny day. How are we going to get this guy. outside? 35 liters, 100%. We My. respiratory therapist, Kim, managed to. put a couple of oxygen tanks together. And we were able to get this guy into a. wheelchair. And we wheeled him outside.

And uh he told me this uh weeks later. But he says, "You know, that first day. that you got me outside in the sun cuz. we did this for like 7 days in a row. He said, "That felt so good.". Um he after just 1 day dropped down from. 35 L to 15 L. 15 L of of oxygen. And then down to 12, and then down to 8 the next day, and. then down to 5. 5 days The amount of. oxygen he was inhaling to keep him. alive. Correct. So, in other words, we. were titrating down the amount of oxygen.

that we had to give him to maintain a. saturation in the 90s. In 5 days he was. discharged home without oxygen. Now, obviously that's an anecdote, right? That's not a study. But, I'm. looking at the risks of getting people. out in the sun for 15-20 minutes. There's not a lot of risk to that. And. if there's a benefit, I thought it was. worthwhile doing. We we need to have. larger randomized controlled trials, but. it got me down the road to looking to. see what what was it. about sunlight.

that was affecting this change. And you. know what? There was There's There's. ample data. There There was a study actually that. was done. in in Europe where they looked They. said, "Okay, here's COVID. COVID's going. up. When does COVID go up? Is it because. of temperature that changes? Is it. because of humidity?" And the answers to. both of those were no. Do you know what. predicted when countries were to have. their first surge in the autumn of 2020? There was a study that was actually done. on this. It was latitude. It started in Finland.

and then real it went down the entire. continent. The last country in the in. the autumn of 2020 to have a COVID surge. was Greece. So, as the sun is literally pulling down. into the southern hemisphere, as the. shadow starts to go over Europe, that's. when we start to see. COVID surges one by one by one. There. was Yeah. Is that Is that because COVID. and the sun aren't friends? So, if I it. makes it harder to spread because, you. know, if I put COVID on this table and. then I put sunlight on the table, the.

COVID is going to die. Yeah, it's. possible. Although we now know that. COVID probably doesn't spread too much. through contact. It's it's more of an. airborne thing. So there there was a. study that was done at the University of. Edinburgh. And they looked at this very question. that we had talked about earlier about. vitamin D. They looked at the United. States in the in the wintertime. So and they eliminated the southern part. of the United States because in the. southern part of the United States you. can actually get some vitamin D in the. wintertime. So they just looked at the. sort of the northern portion of the.

United States and they were able to show. that the more sunlight there was in. particular areas, the lower the. mortality from COVID-19. So they said, "Well, this is. interesting. What about in England?" So they they did. the exact same study in England and and. sure enough of course they didn't have. to eliminate any part of England because. the whole country doesn't get in any. vitamin D in the wintertime. What they. showed was that again, certain parts of. the country in England as you know, get. more sunlight than other parts. Well, those areas that got more sunlight had.

lower. mortality from COVID-19. Then they took. the same. They predicated the same study and they. looked in Italy. Exactly the same finding and they. published this. And they said in their. study and this is what really amazed me. They said, "The fact if this is causal, they say." They said that. this might actually show a possible. public health intervention. The fact. that it is completely independent of.

vitamin D means that there's something. else going on. There was a study in 2011 in Sweden. Yes. Is that linked to this? >> No, this is a completely different. study. But that that's also a very. important study. So the Swedish study is. is is groundbreaking. Um. This was a study where they asked 20,000. 20 to 30,000 Swedish women. about their habits in sunlight. And they divided these women into three. categories. Those women that did not get.

a lot of sun, those that got a moderate. amount of sun, and those that got a lot. of sun. And they followed them for 20. years. And they they kept a track of. each one that died and what they died. of. And when they were done with that, they. were astonished because what they found. was that. the women who had spent most spent the. large amount of their time outside or. that spent the most amount of time. outside. had. the least amount of mortality from. cancer, from cardiovascular disease, and.

non-cardiovascular disease. And those. that spent the least amount of time. outside had the highest levels of that. The magnitude difference between those. two was so much. that they were able to show that women. who in Sweden. who spent the most amount of time. outside and smoked. had the same mortality as those women. that did not spend as much time outside. and did not smoke. They were equal. They were equal. In.

other words, being in that category of not spending. much time outside in the sun was the. same risk factor for death as smoking. How do they know it wasn't linked to. exercise? How are they able to establish. causation cuz that's a You're absolutely. That's an excellent question. So, the. the difference here as you go up is this. is a this is an association study, okay? So, the question is is how can you get. causation from association? You can't. But, if you look at the Bradford Hill.

criteria, there is a way that you can. potentially make a a strong argument for. causation if there's something called a. dose-response curve. In other words, if. you can show you're not just comparing. two things, but you're comparing three. or more, if you can show that as you. increase. the variable, that there is a change in. the. the outputs that is strongly suggestive. of potentially causation. By the way, this is exactly what we did to show that. smoking causes lung cancer. Obviously,

we can't do a randomized control trial. here. You get to smoke, you don't get to. smoke. We'll follow up in 20 years to. see who has lung cancer. This is exactly. what we did. We showed that that there. was such a strong association with. cancer risk with smoking that we were. able to say through association that. smoking causes lung cancer. By the way, Richard Weller. was a dermatologist in England uh did. just last year a very similar study as. to the Swedish study except it was 10. times bigger. and he did it with both men and women.

He found the same results. It was a UK Biobank study. What did he discover? He discovered that. either from. from solariums or from um or being. outside using solar radiation data. uh he was able to show both on their. their questionnaire and also where they. lived. that the more light that they had the. lower their risk as of of um mortality. uh and um and cancer mortality. So, the.

question was. does it increase melanoma? What's melanoma? Melanoma is is a skin. cancer. So, that's the big risk. That's. the big risk that everybody's concerned. about. You go out into the sun sun and. you're going to get skin cancer. And he was able to show in that study. this was like three three 400,000 people. in this study. UK Biobank study, Richard. Weller. He was able to show that. there was no increased there's no. statistical increased risk of melanoma. incidence but there was.

a reduction in non-skin cancer. mortality. Okay, so so here's the trade-off. If you. want to go out into the sun in England. okay? The benefits are you're going to have a. reduction. in non-skin cancer mortality. So, everything other than skin cancer? >> Correct. On the other hand, there's no increase. in melanoma incidence. So, that caused. him to write an a an op-ed and publish.

it. And actually, you can look up this. op-ed. It's a great op-ed. Uh it. published in a um. in the Journal of Investigative. Dermatology called Sunlight: Time for a. Rethink. Where he goes through the. arguments. And he's actually shown And. there's been a number of changes that. people have making around the globe. So, public health uh. organizations that are saying now, you. know, before we have said. that, you know, the the sun is a deadly. laser. And you should avoid it at all costs.

We may need to rethink that. So, you telling me that essentially 15. minutes in the sun every day turns on a. switch in my body that improves my. mitochondrial function, which is going. to impact a variety of different parts. of my health. Is that essentially what. you're saying? Essentially, yes. Uh and. and we're we're looking And this is in. an environment where where we are. spending less and less and less time. To give To give you To put in. perspective, if we were on a British. ship 300 years ago, and I came to you.

and I said, "Do you see this little. yellow fruit? Just by eating a little. bit of this yellow fruit, all of this. disease that you're seeing around you. with your fellow shipmates is going to. go away." That that would seem almost. incredulous, right? But, that's exactly. the case. We We are. The scurvy of the 21st century is the. lack of sunlight. Everything is inside. Uh we we avoid the outside. We avoid. discomfort. We avoid high temperatures. We avoid low temperatures. We uh are We.

used to go out and play sports. We now. are are playing virtual sports on on. pads. We have windows. that are specifically designed, especially here here Southern. California, to eliminate infrared. lights. Because why? Infrared lights. comes in and it heats up. One of the. interesting things we didn't mention. this about infrared light is the way. that we interact with infrared light. You can You can tell this on your own. You go outside. and. close your eyes. You can tell which side. of your body the sun is on. And the.

reason is is because that infrared light. not only can penetrate through your. body, it's also penetrating through. clothes. very easily. And you can feel that. That That heat. that you're feeling is the infrared. light going through this going through. the clothes, going through the skin, and. interacting with your heat receptors. that are well below the surface. Um so all of this. All right, guys. Pretty good. I got. Steve. The guest is here. Ready? Come in. OH MY GOD, STEVE. LOOK. WE DID IT. THIS IS a the Boncharge face.

mask. It's good for blemishes, wrinkles. Uh clears up the skin. It's red light. Have you not used it before? No. You. tried this before? It's um. It's really, really good. It shines red. light on your face, which helps increase. and boost collagen production. I. actually found it out cuz of the missus. Seeing her wearing it, she terrified me. a couple of nights in a row. Um I. thought it was to scare people with, but. actually it's really, really good for. your skin.

How long does the average American spend. indoors? Does the average Brit spend. indoors? Good question. They're almost. identical. I think the Brits spend a. little bit more time outside than. Americans. The The last number for. Americans was 93%. and uh Brits is 92%. >> Were we born to be outside? I think so.

You think our ancestors probably spent a. huge amount of time outside? Yeah. And. And And if you think about when I say. outside, that also brings into play a. number of other of the new start letters. that we haven't talked about. Uh. exercise. You're much more likely to do. good exercise outside. You're much more. likely to get air that's that's the. right type of air outside. The other aspect about infrared light, briefly, is that trees. are highly reflective of infrared light.

In other words, if you're in an. environment where there are trees are. present, you're going to get much more. of this beneficial infrared light than. if you're in a concrete jungle. So So So plants like this. In fact, the. way that we measure the deforestation of. the Amazon is through satellite imaging. that looks at infrared light because it. reflects infrared light back. So, the best thing best situation to be in. is to be outside. on a green.

on a day where where there's lots of. green trees. We've known for We've known. for decades that people who live in. green spaces. do much better in terms of diabetes, do. much better in terms of hypertension, mortality, all of these things. >> Depression. Depression, all of these. things, yeah. And And when you think about this, um. you bring up a point in terms of of. correlation. How do we know it's not. depression? We used to say, "Well, people who live in green spaces have. more money.". that people have They have more access.

to things. Maybe that's what we're. saying. I just have to tell you this study. There was something called the. GreenHeart study in South Louisville, Kentucky. They did an amazing thing. They took this 4-square-mile area. in South Louisville, Kentucky, urbanized. area. And they measured everybody's hs-CRP. What is hs-CRP? Highly sensitive. C-reactive protein. It's a marker of. inflammation, and it's been correlated. to bad things like stroke and heart. attack. So, if you have high levels of.

CRP, that's not good. So, they measured every They measured. about 700 people. And then they did something. extraordinary. They purchased 8,000. mature trees, dug holes, and planted 8,000 trees into. 4-square-mile area. And these are trees. with leaves on them. 2 years later, they come back and they. measure all 700 people in their study. Repeat the hs-CRP. Dropped by 13 to 20%, which correlated.

to about a 10 to 15% reduction in. strokes. These people didn't change their. socioeconomic status. They didn't. institute an exercise program. And so, really, it kind of shoots in the heart. the idea that the advantage that we see. with green spaces has to do with. something else that we're not measuring. I actually believe that we'll talk about. fresh air, too, that things like. these plants, but much bigger. This is kind of like a. bonsai plant. But But trees outside,

they actually have a benefit. And what. they represent, again, is. these things that. don't leverage the other parts of your. body in the in terms of the chains uh. that make all of the chains bigger cuz. they're they're they're they're having a. benefit. But you can't get the benefit. of this if you're inside a house. So, what should we do about this in terms of. how what changes should I make in my. life to capitalize on this? Um this is a. This brand here is called Bon Charge.

They do these Yeah. these red light. devices. They do like red light saunas, blankets, um masks. They're actually a. sponsor of mine because I I started. wearing this and I think they they found. out. And I started wearing it because of. my girlfriend. Yeah. She was wearing it. every day and I got curious. And so, I. as I always do, I'm always super. skeptical. Sure. So, I went on online. and started looking at some of the. research. And I was shocked. Yeah. >> It made no intuitive sense to me that a. red light mask or any like red light. device could have a profound like what I. see is a profound impact on my health.

Like I didn't believe it Yes. >> to start with. Yes. >> like woo-woo stuff to me. I I Yeah. >> But I couldn't disprove it. Right. All. the studies, many of which you've. referenced, um supported that it was. having a profound impact. And as I said. on this podcast before, my girlfriend's. always right. She's like always ahead of the curve and. always right. So, I started wearing her. mask and now I have my own from Bon. Charge. >> Yeah. Ish. Do you recommend these kinds. of things? I I think it's reasonable to. do. I will say this. Um if you are. getting enough infrared light from the. sun, what we find in studies, not.

particularly with the mask, but we find. in other things, is that these these. other areas don't have as much efficacy. It's almost to say, if you're on a ship. with a bunch of people with scurvy and. you already have a diet that's rich in. vegetables and fruits, eating an extra. lemon is not going to be that. beneficial. So, what do you do? Like a. lot of doctors do, we have shifts that. go from 7:00 a.m. to the p.m. So, you're. in the hospital, you're not going to get. outside. So, at lunch, I try to get. outside as much as I possibly can into. the sun for my 15 minutes. >> What if you live in a cloudy country?

So, that's a good point. Uh clouds, because they are water molecules, will. absorb a lot of the infrared lights. And. the problem is is that that's the. exactly the type of light that you want. to get. However, even on a cloudy day, being outside, you're going to get more. infrared lights than if you were inside. Okay, so I still get the light I need. when it's cloudy, but I just don't get a. lot. Yes, exactly. >> Is there anything I can do to get if. it's super cloudy and I know I'm going.

to be indoors, what do I do then? Yeah. So, the light. the type of lights that we have inside, like these ones? Like these. Uh and and. and actually, I think the UK and the. United States are very similar in this. regard, is that we really can't get the. old incandescent bulbs. We're on LED or. or fluorescent. And if you think about. what they've done in terms of of these. bulbs, the old incandescent bulbs used to give. you a very broad uh.

spectrum. So, all the way from, you. know, just near blue all the way down. into the into the infrared. The way that. they've made the bulbs more efficient, they said, "Hey, let's stop using energy. to give off this light that we can't see. and give a very narrow spectrum of light. that we can see.". So, think about what they've done. They. have for the first time in the history. of humanity, they are now we are now being exposed to. light. in a very narrow spectrum without.

anything else. Whatever in the history. of of humankind, when we light a candle, when we would go outside into the. sunlight, when we would have a kerosene. lamp, we were getting full spectrum. In other words, we were never getting. blue lights without red lights. Now, we're starting to get blue light without. red light. So So do I change my bulbs? It's difficult to do that because you. can't pick up in these incandescent. bulbs. Which brings me to I mean at. least at least in the United States, we.

have laws now that outlaw the regular. selling of incandescent bulbs because of. energy efficiency. Oh yeah. I'm on. Google now and I've typed in. incandescent bulb. So there's something. called a general service lamp, which is. what the type of bulbs that you could. plug in. But if you decide that you want. to get a. bulb that you put into your microwave or. a bulb that you would do into a type of. chandelier that's a special type of. chandelier, those are still available. You can still get incandescent bulbs for. those. What about these kinds of bulbs?

Is that an incandescent bulb? That's a. That is a That is an incandescent bulb. Again, for these special type of lights, but I'm I'm talking about the light like. the like the the good old fashioned A90, I think it's called, light bulb that you. just screw in. Those are. the 120 watts, those are getting more. difficult. You It's harder to find. You. can't go down to your Home Depot and and. find them there. So Glenn Jeffrey um and. this is this is a preprint that he is. he's done. He actually took. people.

with that were working in this. environment with LED bulbs. He's. actually It's not peer-reviewed, it's. not published yet, but it's a preprint, it's available on the internet, so I'm. not speaking out of class. And what he did with 22 people is he. switched out. these LED bulbs and put in incandescent. bulbs. And there was a there was a 25%. improvement in in color differentiation. in his study. What does that mean? They were able to. distinguish colors 25% better than they.

were when they were exposed to LED LED. When I say LED bulbs, these are the. bulbs that are high on the blue end. Um so why would that be? The retina, which is the back of your. eye, where in the light is coming in, there's these cones that are. tremendously metabolically active. They're constantly updating, sending. neural signals to the brain. And there's It's the It's the one tissue. in your body with the most amount of. mitochondria. And it's because they have. to supply a lot of energy. As somebody.

gets older, that mitochondria is not producing the. same amount of energy. And so, the the. ability of the energy that those cones. have to draw on to do their work is. less. And so, they're not going to do. the job as well. If you can perhaps increase the. the. the amount of output of energy from. those mitochondria, you could improve. the the the ability to visually. perceive. And and and. Glenn Jeffery has done this study. already, where he.

for just 3 minutes, 670 nanometer light, very similar to. that mask, in the eye, only in the. morning, improved. those people's ability to to to to. visualize and actually see. And what does that mean for the broader. picture of our health? >> would be able to distinguish colors. better and actually improve their. vision. That's basically what it means. Um and so, the question goes back to the. first question that you had at the very. beginning of the podcast, which is what.

is the effect of low. energy output from the mitochondria. Well, it depends on what tissue the. mitochondria is in. And so, if it's in. the eye, then it's going to be a bit better. visual perception. If it's in the brain, it's dementia. If it's You know, you see. You see what I'm saying? So, what we. start to see. is we start to see that a myriad of. different diseases are affected by the. sun. I I challenge anyone to do this. If you. look at a publication in the United.

States, I've seen it, where they map out. the amount of deaths. per in a calendar day. Cardiac disease, respiratory disease, kidney disease, pneumonia, all sorts of diseases, infectious. diseases, non-infectious diseases. You. will see a very clear pattern. The maximum amount of deaths every year. occurs. within a month after the shortest day of. the year. So, we're talking December, January.

We see the most amount of influenza. deaths at that time. We see the most. amount of cardiac deaths at that time. We see the most amount of kidney deaths. at that time. So, you might ask, well, that that's. because. that's because people get together at. Christmas time and they spread the germs. around more and we have Thanksgiving in. late November here in the United States. and and and and that's what's going on. The problem is is if you look at. Australia, which is on the other end. So, when is.

their longest day of the year? Their longest day of the year is in. December. And that's when they have the least. amount of deaths, despite the fact that. they're all getting together for. Christmas in December. So, that doesn't. fly. It's exactly the opposite. The most. amount of deaths occur in Australia, in. the Southern Hemisphere, in June to. July. That's their winter. And so, what you see is deaths are. correlated to the length of the day. This is the reason why whenever they.

have to whenever they show you deaths in. the year, they always have to seasonally. adjust it. And the length of the day is. a proxy for the amount of sunlight. >> Absolutely. You're much more you're much. more likely to get sunlight. on the longest day of the year than the. shortest day of the year, especially. when and and this is well known. There. there are some months, especially in. people who are doing shift work, like. 7:00 a.m. to 7:00 p.m., there's. literally like December and January, you. will not see the sun because you are. going off to work before the the gets up.

and you're you're coming home after the. sun is long set. So, you're not you're not able to see. the sun, and so you could go literally. weeks. without seeing the sun at all. Is there an optimal time of day to get. sunlight? Yes. So, optimal time of day to get sunlight. would be for those that are concerned. about getting damage from ultraviolet. radiation. As we talked about, when the. sun is low in the sky, that's going to. be beneficial because the ultraviolet.

cannot penetrate obliquely through the. atmosphere as well as long wavelength. radiation. So, when the sun is coming. up, So, in the mornings? In the mornings, and when the sun is going down in the. evenings. That's going to be the time. where you're going to get proportionally. more infrared light and. the least amount of ultraviolet light. Now, when the sun is directly overhead. at noon, you're going to be getting the. most amount of infrared light at that. time, but you're also going to be. getting a lot of ultraviolet radiation. And so, if you're not someone that's. gone out into the sun a lot, you may.

want to avoid this period of time. Or, as we talked about, put on a broad-brimmed hat, put on. clothes. I mean, more clothes because. as we said, ultraviolet light does not. penetrate through clothes very well. But, infrared light can. Does it matter. where the sun is hitting on my body? Shouldn't. So, if I go outside and I'm. wearing a big hat, it's obviously going. to cover my eyes, my face, Yes. but. it'll be hitting my legs. For the. purposes of we're talking about with the. mitochondria, it will not matter. However, if we're talking about.

circadian rhythm, if we're talking about. getting circadian rhythm, that pathway. is through the eyes. So, you want to. maximize light through the eyes. Yeah, so so this type of a light is called the. SAD light. So, your question had to do. with what part of the body does it need. to touch? So, or need to be. touching. So, for the effect of the. mitochondria and and the metabolic. effects, it it should not matter, okay? For this type of a light though, what. we're looking at is circadian rhythm. And that's a that's a completely.

different system that we're talking. about. That's not mitochondrial. That. has to do with the internal clock that's. in your brain that is regulating when. all of these things in your body. happens. And this light is about 10,000. lux. Lux is a way of measuring the. brightness of light. And what studies. have shown is that when you shine this. type of a light into your eyes, it had. it it's the way of of adjusting your. circadian rhythm. You don't have to If. you have a clock and it's not set to the. right time, there's a little thing at. the back that you can pull out and you. can change the time. Yeah. That pulling.

out and and changing the time about when. things happen in your body is affected. most. by light. And light can actually shift. it one way or the other depending on. when you're shining that light. If. you're shining the light in the morning. time, and this is what a lot of people do is. they'll use these these what they call. SAD lights. SAD stands for seasonal. affective disorder. These lights, especially in the morning, have a way of of not only setting your. circadian rhythm and making sure it's on.

track, but also reducing depression. There's a there's a portion of your. brain that receives light information. It's called the perihabenular nucleus. It's a long name, but it's it's it's. back there. And if it doesn't get. stimulated, it can cause depression. And so so for people who live at high. latitudes, uh further away, closer to the poles, where the sun is getting up very late in. the morning, they're already off work. inside, this can actually be very. beneficial. So, what I would recommend. doing, you can pick these up pretty.

cheaply on Amazon for about 20 bucks. But they should generally be about 11 to. 16 in from your face. And uh what people should be getting is. about 3,000 lux hours. Uh and what I mean by lux hours is you. multiply the lux times the amount of. hours that you're wearing it. So, 3,000. is where you ought to be. Because this. is 10,000 lux, you only have to look at. it for about a third of an hour or 20. minutes, and that should be enough. So, is this a replacement for going outside?

It's a replacement for going outside. because of the fact that you're living. at a very high latitude and the sun is. not up, and because of the job that you. have, it's going to uh it's going to have that. effect, but realize that this will not. replace the effect that the sun has on. your mitochondria. This is only to. affect the effect that lack of sunlight. has on depression. Okay. What if I'm. looking at the sun out of a window? It depends on the window. So, you're not. still the window is going to be reducing. the amount of lux, so I would not. recommend if you can, I would not.

recommend I would not say that staying. inside looking out the window is the. same as going outside. That's number. one. The other thing that you have to. understand is a lot of these windows, especially if they're modern windows, will be specifically designed to reduce. infrared light. I want you to give some. me any information you have yeah as it. relates to light health Yeah. that will. improve my life, things that I can act. actionably do tomorrow. Obviously, one. of them is that I'm going to go outside. and make sure I get some sunlight. ideally in the morning. Yes. We talked. about this sad lamp.

for people especially that live in. certain countries which it which have. less sunlight. >> Correct. to set their circadian rhythm. and to help with things like mental. health. Is there anything else I should. be thinking about or can do or change? Yes. So, just like we had in our. mnemonic of new start, rest and exercise. both at the same time and then yet the. short of opposite of each other, it's. important to have darkness. Okay. It's important to have darkness, and this is a real issue. This is one of. the biggest issues is the fact uh there. was a study that was published recently.

and the title was dark days and bright. nights, and that correlated with. uh increased mortality. I mean, that's how most of us live. That's the problem. We have dark days. and we have bright nights, and what we. really should be having is bright days. and dark nights. So, just as important. as it is to have bright sunlight and. getting outside in the middle of the. day, we also need to start working on. getting darker nights as well. And how. do we do that? Turning things off. Uh getting the screens away from our.

eyes. Um these are really important. because the screens have a lot of light. and the light what's going on here? This. is the reason why it's important. There's two reasons actually. Is the. light that's going into our eyes is is. doing two things at night. Number one, it is shutting down melatonin production. from the pineal gland. And as we just. talked about, melatonin's a very. powerful antioxidant that's very. beneficial. The second thing that it's doing is it's. confusing your circadian rhythm. You. see, your circadian rhythm is designed.

to see light as day. If your If your eyes are seeing light, your brain thinks it's the day. So, if. it's 10:00 at night and your eyes are. seeing light, your circadian rhythm is. saying, "I must have made a mistake. I. thought it was 10:00. It must not be. 10:00 because look, there is light.". And so, what it's going to do is it's. going to adjust itself. and delay everything because it's. saying, "Well, it can't be 10:00 at. night. It must be 6:00.". And so, therefore, when you would.

normally feel tired and sleepy at 10:00. at night, after a number of days of doing this, you're not going to feel sleepy until. 1:00 in the morning. These devices we have, they spit out a. lot of blue light, right? >> Yes. Is there a way to like turn that. off? Yeah, actually a lot of these come. with uh with with tied to the clock. where after a certain time of night, it. will shift its its uh spectrum to a more. red spectrum. So, it's giving you less.

blue light. The problem is is that while. the sensor in your eyes are tuned more. to blue light, it's not just blue light. So, really the solution The best. solution is to turn off the lights. The next best solution is to have more. of a red shift. or you know, put these glasses on at. night. So, these are blue blockers. They're. trying to eliminate blue, but I'm I'm. still getting light in and that's enough. light to shut down melatonin production. Even with those on?

>> Yeah. Absolutely. But you're telling me. these help? They're better than not. turning off the light. And you're saying I still get light in. because there's light coming over the. top. >> Even even that light there is still. going to bleed and it's going to bleed. into that part of the spectrum and cause. melatonin to be shut down. Yeah. So, it's just the eyes are the sort of. the barometer for Correct. >> what time of day it is. >> Correct. And and the problem is is that. even when you close your lids, light can still get through the lids. What do you think of these sleep masks? >> I think they're I think they're great.

in terms of the fact that we now know. that closing your eyelids still can. allow some light to go in. So, if you're. in if you're sleeping in an environment. where, you know, light is out of your. control. If you're living in the city. and you can close your blinds but. there's still light that's coming in, these things could actually be very. beneficial. I don't recommend. nightlights in bedrooms. You don't. recommend. >> not. I Even even clock radios or air. conditioners with LED displays on them.

That's that's just like total light. pollution to your bedroom. Your bedroom. should be as dark as possible. What if I. have those lamps that don't have blue. light in them? Cuz I think my girlfriend puts some of. those by the bed. Yeah. Do they do. they still not great? >> Again, the best thing is no light. The. second best thing is light with no blue. light in it and then the worst is, you. know, blue light. What about candle light? That's interesting. Um there was a study that was done. where they compared someone reading at.

night with a book with a light bulb. shining on it versus the LED, uh you. know, like a Kindle or whatever, okay? What they found was that there was a lot. more light coming out of the Kindle than. there was just reading the book with the. with the lamp. And it and it delayed. sleep onset. So Which delayed sleep onset? The. Kindle. The Kindle. Yeah. It delayed. sleep on enough to actually shut down. actually delay the circadian rhythm and. shut down melatonin production. So the. answer to your question is is candle.

light's great. The only thing I'd be. concerned about is just the fire risk. Yeah, cuz you fall asleep with that. thing. >> Exactly. So the adjacent topic there was. vitamin D which we we touched on a. little bit. Do vitamin D supplements. work? Oh yeah, certainly. They do work. I've tested them. Yeah, there's a number. of studies that have come out. Martineau. actually published in the British. Medical Journal. This is back. before 2020. It was a meta-analysis of randomized. controlled trials showed that people who. supplement every day with vitamin D had. lower risks of acute chest syndrome.

The other one there was a recent study. that came out that showed that people. who supplemented with 2,000. international units a daily of vitamin D. had a lower risk of all cause autoimmune. conditions. We're talking rheumatoid. arthritis, Crohn's disease, ulcerative colitis, you. name it. That was that was a. study that came out that we actually. reviewed that on our on our Med Cram. channel. Cuz I've heard before in the. past that a lot of vitamin supplements. we take don't even get into our. bloodstream and into our bodies.

Yeah, so so vitamin D is very. interesting. It is a supplement and it is a vitamin. but it's also a hormone. Okay. It's it's it actually manipulates. um. DNA production. So it's it is quite. interesting. But these these are are. well described randomized controlled. trials. So if you're looking at the. autoimmune condition, this was actually. a study that was designed looking at. cardiac disease. They actually had two. arms, one with. omega fatty acids and and vitamin D and.

they showed that in the vitamin D group, there was a statistically reduction. statistically significant reduction in. autoimmune conditions. I supplement with vitamin D. I just. Here's the. Here's the concern I have is if you are. going to supplement with vitamin D, make sure that you get your levels. checked. Why? The reason is just because it is a. fat-soluble vitamin and it is possible. to take too much. What happens if you take too much? It.

can affect calcium metabolism and you. can have issues with calcium, too high. of levels of calcium. It's very rare, um but it can happen. And I don't mean to say that in a sense. that I would I dissuade people from. supplementing because I think. supplementation can be good, but it at. some point you want to get a level. checked to see where you are. The other. reason is is because. based on your body habitus, based on. your skin color, because people with. darker skin, it's harder for them to. make their own vitamin D. They need to.

be more time outside, especially if. they're at high latitudes. So, like me. living in the UK. >> Exactly. I need to be outside more. It's. going to be harder for you to make as. much vitamin D as as somebody who for. instance if you were living at a lower. latitude or if you had lighter skin, yeah. What is vitamin D doing in my. body? Ah, good question. Lots of things. So, vitamin D if you were to look at the. the structure of vitamin D. Actually, I. actually did research on this. interestingly in college. I used to make. starting material for the graduate.

students. It's It's a lipid-soluble. molecule and because it's lipid-soluble, it's able to go right through into the. nucleus and actually go onto the DNA and. combine with proteins that actually. affects the transcription of your DNA. So, in other words, depending on which. cell type we're talking about, it can. cause a lot of interesting changes. So, it affects calcium metabolism. There's. vitamin D receptors on your immune. system. So, uh it affects your immune system,

affects calcium metabolism, a whole host. of things. My team did some research and. found that approximately 1 billion. people globally have a vitamin D. deficiency. Not surprising. >> 50% of the global population has. insufficient levels of vitamin D. Absolutely. Yeah. Yeah, so the the issue is is that as the. world becomes more industrialized, as. the world becomes more well-off, they're able to create dwellings and. they're able to air condition those.

dwellings. And we, as human beings, tend. to avoid extremes. We don't like things. too hot, we don't like things too cold. Well, I mean, let's face it, in our cars. we have something called climate. control. We can set the We can set the. temperature and that's what the. temperature is going to be. There is. this other implications which we can. talk about in terms of hydrotherapy, perhaps, if we get to that. But, um the. issue is is we don't like those. extremes. We don't like going out into. the sun. And when we don't do that, we. we suffer the consequences. Is there a.

way for me to get vitamin D without. supplementation and without going into. the sun? Yes. Yeah, it's in uh certain. foods as well. Mushrooms, for instance, uh certain types of fish. They're um. they're they they have vitamin D in them. as well. This is a strange question. But, do you. think our body knows. which foods we're deficient in? And really what I'm saying there is. if I'm vitamin D deficient, do you think. there's a part of my body that knows. that I I need to eat mushrooms? >> a good question. >> makes me hungry for mushrooms. I don't.

know about that particularly. I can say. this, though. In people who don't get. enough sleep, we tend to have a predilection to eating. more carbohydrate-rich foods. That one we do know. Okay. And and we. can and this is the reason why people. who. This is the reason why many scientists. believe that people who don't get enough. sleep tend to have food choices that. tend to put weight on. Every single one of you watching this. right now has something to offer, whether it's knowledge or skills or. experience, and that means you have.

Visit. stevenbartlett.stan.store. and get yours set up within minutes. Of these cards that we have left in. front of us from the New Start. framework, which one are you compelled to talk. about next? Water. Water. Yeah. Okay, so tell me what you.

mean by water, cuz people will think, "Yeah, I drink enough water." Well, first of all, we I don't think we do. drink enough water, but. I what what everyone talks about, you. know, the internal use of water, and it. makes sense. But, as I was talking about before, the. the external use of water can actually. be very impressive. And it has to do. with uh body temperature, and it has to. do with the immune system. So, we'll talk about water, but let's. sort of set the framework for that. conversation. Your immune system is broken up into two. into two types. There's the innate.

immune system and the adaptive. We've become very familiar with the. adaptive immune system during COVID, because all the talk was about. antibodies and antigens, and the fact. that SARS-CoV-2 was mutating, and would. the vaccines that made antibodies. against them be uh still functional. All. of that, where we have like where we. literally have a key with a keyhole that. it fits into and turns the lock and. these antibodies and they fit, that's. all the adaptive immune system. It's. very important, but it completely.

eliminates or or removes from discussion. the innate immune system. The innate. immune system is really the body's first. defense. And what's happening there is there's. these cells that are circulating, cells. like monocytes and natural killer cells. and a number of other other cells which. scour the body always looking for. something that looks. foreign to it. And it can tell based on. the molecular patterns of these of these.

invaders that they're not supposed to be. there and they should be eaten up. The major effector of this innate immune. system is something called interferon. Interferon is a very. important molecule in the body and it is. effective it is so effective. at preventing viral infections that just. about every single viral infection that. plagues the human body today has a.

defense mechanism against interferon. It. is it is a prerequisite. There's no. self-respecting. virus that can think it it can infect a. human body without dealing with the. issue of interferon. Period. Think about interferon. as the security guard at the bank. And. if you are want to rob a bank, you've. got to have a plan for how you're going. to deal with the security guard. Otherwise, you're not getting the money. Does that make sense? Yeah. So, there was actually an article that.

was published a couple of years ago. where they talked about this this battle. between interferon and emerging viruses. and what viruses are doing to try to get. around interferon. You may recall that back in 2002, we had. an outbreak of something called SARS, which especially was pretty bad in. China, but also in Canada. The reason. why we were able to secure that outbreak. was because that everybody who came down. with SARS. developed a fever. And so it was easy to tell who those.

people were, and and we were able to hospitalize and. isolate them. The issue with SARS-CoV-2, and indeed. many infections like the common cold, is. that you don't necessarily get a fever. And. fever is really important. And you're. like, what does this have to do with. water? We're going to talk about this. Interferon. production goes up with temperature. And in fact, the body's. fever mechanism is one of the ways that.

it tells the body that it needs to. increase interferon to deal with the. viral infection. Is that why you feel. hot? You feel hot You may actually feel. cold. And the reason why you may feel. cold and even have chills is because the. way you feel is a product of what your. temperature is and what your thermostat. in your body is set to. So, if your body. and your if your body's thermostat is. saying, "Okay, here we are at 98.6. or I guess in in terms of Celsius, 37°.

and you develop an infection, the body's. going to say, "Whoa, we have an. infection and we need to increase the. body temperature. We're going from 37°. or 98.6 up to 38° or or 100.4.". Because your actual body temperature is. below where your body wants it to be, you're going to feel cold. You're going. to shiver to try to increase that. temperature, so you go up with that. Now, once the fever is done and the. infection is done. and it comes down, you're going to have. you're going to break a sweat. So,

that's that's why when someone Oh, he's. sweating. That means the fever is. breaking. That means your temperature is. coming down. So, you're typically you'll. feel cold, you'll feel like you're. shivering, you'll want to get into bed. and and and put the covers on, and. that's when your temperature goes up. That and and that's for a reason. Because what happens when the. temperature goes up in your body is that. creates an environment where the virus. that can't replicate very well. All. viruses really cannot replicate very. well at high temperatures, including. SARS-CoV-2. It's also a signal.

to your body to produce more interferon. So, there was a study that was published. last year where they looked in mice, which by the way have the same body. temperature as we do, and they found. that there was like five different. regulatory proteins, all of which led to. one endpoint, and that was to produce. this thing called interferon. All of them jumped in production when. your body went from. 30. 7° to 38°. That's basically right below.

a fever, right? So, the point the take-home point that I got. from all of that was that we should not. really be treating fevers unless they're. so high that there's other complications. that could occur like, you know, uh. racing heart rates or or um or having. seizures. But, we do this all the time. We treat fevers because it feel makes us. feel bad, and we think that by treating. the fever we'll feel better, but what. we're actually doing is we're we're.

cutting the legs out from our immune. system because part of the immune system. response is to generate a fever, and the. and the fever generates interferon. Now, I I don't want to overstate this, but. let's compare the innate immune system. to the adaptive immune system. The. adaptive immune system is pretty. specific for a particular variant of a. virus. And for a virus that mutates very. rapidly like SARS-CoV-2, the immunization may be very good in. terms of binding, but if that. that virus mutates,

that binding is going to be affected in. some way. It may not affect. hospitalization, but maybe in terms of. of preventing infection. Do you know you. understand what I'm saying? So, the. different variants, we had the alpha. variant, then we had the the delta. variant, then we had omicron, etc. Those. are material changes for the adaptive. immune system. For the innate immune system, for. interferon, it doesn't matter. Interferon is just as effective against. alpha as it was for delta as it would be.

for omicron. So, so let's set this up. again. Water. We said that water has a very high. specific heat, which means that if I. apply hot water. onto the human body, it's able to. transfer heat. This is why people get. burned with boiling water. We don't obviously want to burn anybody, but if we're able to put them into a. sauna, if we're able to put them into a. spa, if we're able to use hot towels and. apply to the human body to heat up their. body to cause a sweat,

in other words, if we're able to induce. artificial fevers in patients who have. these infections, there seems to be evidence that the. interferon response will be will be. better. Uh there was a study that was. done looking at lymphocytes and taking. them out of the human body and at. different temperatures, once it hit. about 38, 39°, there was off-the-charts. uh 10 10-fold increase in interferon, which is exactly what you would want to. have. Now, how do I know that interferon.

levels are so important in things like. COVID-19? Well, there was a study that. was done that showed that high levels of. interferon. correlated with more mild. uh. uh SARS-CoV-2 infections and that people. that had low interferon levels had very. severe COVID-19 infections. So, you're. suggesting that we should. be in the sauna more often? Yes, and. it's based on data. that is. has been well documented in in the.

Finnish sauna. realm. So, people who use sauna. four, five, six, seven times a week are. more likely to have less. uh death from cardiovascular disease. than people who use sauna once a week. And and in Finland, once a week is kind. of the standard. And why do they say to. do hot and cold therapy together? So, they would. I would argue that the reason why it has. been argued to do this, and this goes.

back to uh a number of papers that have. been written back over 100 years ago, is. what you're doing when you're doing hot. for a long period of time, let's say 20. minutes in the sauna. And what you're. doing is you're heating up the body, and uh and and the whole purpose of that. is to increase the body temperature. What the What the cold at the end does. is it does two things, they believe. The. first thing that it does is it causes. vasoconstriction. So, you put a brief. amount of cold onto the body, it's going. to cause vasoconstriction superficially,

so that when you're done, you're not going to lose as much heat. through those blood vessels. And so, you're going to keep the core body. temperature higher for longer, which is. exactly what you want to do. The other. thing that cold water does, again, is. the vasoconstriction. When you It's well. known that when you take a cold shower, your blood vessels constrict, and when. when you look at a blood vessel on end. in in a person who's living and. circulating, there are a number of white. blood cells that are latched on to the. inside surface of that blood vessel.

When that blood vessel contracts, a lot. of those white blood cells that were. stuck get kicked off into circulation, and they go off, and they do whatever it. is that they're going to do. It's called. demargination. So, two things for cold. right at the end. Doesn't have to be. very long, maybe just a minute. It causes uh actually to keep your body. temperature higher for longer, ironically, and number two, demargination. So, that's water, which is the W. Um. of these,

which one do you want to pick next? Which one do you find most compelling? Let's talk about air. Uh real briefly. So, we said that air is. not just the lack of toxins, but. actually benefits. So, first of all, we. want to have good oxygen. We want to get. rid of carbon dioxide, especially in. buildings when there's no ventilation. That's not good. But, there's been. actually a number of studies looking at. plants and trees and the fact that they. can give off things like phytoncides. What's that? These are are aromatic.

compounds that the tree actually gives. off. And when we look to see the effect. of these compounds on the human body, they're actually very beneficial. They. interact with our immune system and. elevate our immune system and actually. can make us more relaxed. There's a. There's a lot of data in the Japanese. literature on on this in the what they. call the hinoki cypress forests, where. they looked at um these CEOs. There's a podcast about CEOs. There's. these CEOs in Japan, and they took them.

from their their jobs and basically took. them up into the mountains of the hinoki. cypress and had them walk around, took. blood tests, and they found that the. natural killer cells, which are so. important in terms of immunity, were not. only increased in number, but they were. also the the um. the the enzymes within them that break. down diseases or viruses were also. increased. So, when they brought them back down to. uh. the city in Japan, they put them up in.

hotels, and they infused. some of these uh these chemicals, these. um naturally produced uh phytoncides, they're called, and they had almost. exactly the same effects in in these uh. in these uh subjects. So, you think plants and being out in. nature could actually be giving us much. more than just clean air. It's giving us. chemicals which help us fight disease. >> Absolutely. So, so again, here's this. dichotomy, inside versus outside. What. do you get when you're outside? We've.

already talked about exercise. We've. already talked about uh sunlight. And. now we're adding to it fresh air. Not. just the fact that you have uh. low pollutants, which is certainly very. important, but the fact that when you're. around green plants, when you're around. green trees, there could actually be a. benefit. By the way, the benefit that. they found lasted for about 7 days. So, just going out one day a week um can. actually have that benefit. I think a lot about carbon dioxide at.

you cuz obviously cuz I I spend a lot of. time sat in the studio recording and um. this is our big LA studio, but uh. in the UK, it started in a really small. room and there wasn't air conditioning. And obviously I sit here sometimes for. several hours with a guest and we're. recycling CO2 at that point. And then I. read a couple of studies that showed the. impact that would have on my cognitive. performance and. That's all true. We actually had on our. on our channel uh with uh Meg Cran, we. had Dr. Joseph Allen out of the Harvard. uh public school of health.

Um and he he showed us. I mean, he. literally uh had the the CO2 meter and. just by cracking the window uh just a. little bit allowed carbon dioxide to. escape and brought down those carbon. dioxide levels. So, very important, absolutely. And for people that work in offices or. you know, travel in hotel rooms or are. inside a lot, what should they be. thinking about and how can they go about. making sure that the air quality is. optimal? Well, uh. the surrogate for that is carbon dioxide. as we mentioned. So, cracking open a. window if they're able to, if there's a.

door that they can uh open up safely. without, you know, compromising. security. These are all things that uh. would be very very beneficial. Even. rolling down the window uh in in uh. in in car and and maybe taking making. sure that we're taking the uh that. recirculation button off when we're when. we're driving. I got friends that won't. won't stay in certain hotel rooms unless. the window opens cuz you know in a lot. of hotel rooms, especially ones that are. high up, you can't open the windows. And. there's also a bunch of devices that we. um. in our UK studio, which is smaller,

we found on Amazon for a you know, not. super expensive, that we just sometimes. put on the floor in the studio just to. see Yeah. how we're doing. I'll link. some of that stuff on screen if anyone's. interested in getting seeing what the uh. CO2 are in whatever room you're working. in. Yeah. What is uh what's next on your. list then here? >> Well, we've talked about I mean, exercise, nutrition, temperance, these. are things that a lot of people talk. about. Not many people talk about trust. When you say trust, you really mean. religious faith and. >> Religious faith uh. something that would give you a a way of.

of dealing with uh stress and and. anxiety. That's really where this comes. down. And there's been actually a number. of studies that have looked at that. So, yeah, basically the Bible. Um or it. doesn't have to be the Bible as well. There's there's other faith um. denominations that that look into this. as well. Number of studies that have. looked at trust in God and how that. relates. to anxiety. So, a number of studies have. shown that people who have a good. faith and trust in a God that is uh or.

or in a religion that is supportive and. not non-supportive, they have less. anxiety, less depression, have a faith. community that they can uh engage with. and and be supportive. Um and I think that that's that the. literature is uh where where as you have. it this the science behind that is not. as strict as it would be for like a. randomized placebo control trial. There's a lot of associations that you. have to say here. Um that it certainly. is one of those pillars that I believe. helps with all of the those links. What.

do you think's going on there? So, you. were telling me that from what the. literature's saying, people. >> who have a faith in a God Yes. are insulated from depression and. anxiety in some interesting way. Yeah, that that's a question that a lot of. people have tried to answer and and they. believe that it comes down to if you. have a trust in in a God that is looking. out for you. and is there on your side uh then that. type of relationship does lead is. associate let's say I shouldn't say does.

lead to because that implies causation. Let's say it's associated with. a reduction in depression, a reduction. in anxiety particularly. Um there's there's an there are some uh. studies that have been done particularly. in uh in Christianity where there was a. study that was published. This is Krauss. and uh out of I believe University of. Texas where he did a survey and he asked. people. how they forgive. And he he divi- he basically divided.

them to two different groups. There were. people that would forgive give. conditionally and people that would. forgive unconditionally. Let me put it. into practical terms. Someone does. something to you. And you say oh that's okay, I forgive. you. The question is would you forgive that. There's some people that would only. forgive if that person came back and and. you know, did some sort of act of. contrition. Like okay, I'll forgive that. person they came back and apologized or. I'll forgive that person they came back. and they did you know, whatever it is. That would be considered conditional. forgiveness.

The other type is unconditional. forgiveness. So in other words, someone. does something to you, you don't see. them again. Or or they've never. expressed any kind of you know, being. apologetic for what they did. They still. get forgiven. So that's unconditional. forgiveness. What they found in the study when they. divided that is that the people. that forgave unconditionally. had less. depression. They had less feelings of inadequacy. They had less anxiety regarding uh end.

of life. They had all They had all of. these They had more The people that. forgave conditionally. had more somatization of depression. So, these were real medical. you know, things that they could. actually diagnose with surveys and and. and tests that are well validated. And. and what what would decide between these. two was how they forgave. So, they were puzzled by this. They said, "Well, what Well, what then what. determines whether or not someone is. going to forgive conditionally versus.

unconditionally?" So, they looked at a. bunch of factors and none of them stood. out except for one. And and the odds. ratio on this was like 2.5. And and it boiled down to this one. question. Do you believe. that God has forgiven you? That was That was the major thing. If if. somebody believed that the God that they. had faith in had forgiven them, they. were two and a half times more likely. to to forgive somebody unconditionally. Which then meant Which then was.

associated with all of these other. things being low, like low less. depression, less anxiety. So, to me that that's an that's that's. fascinating that that in their minds. this is what's actually happening. And. so, there have been randomized. controlled trials where they have When. people are doing therapy, like let's you. say have you have anxiety. There is. cognitive behavioral therapy that we can. do for those people. But, what has been shown in a randomized. placebo controlled fashion is that if.

somebody is of a faith. and you inject into that cognitive. behavioral therapy aspects of that. faith, the cognitive behavioral therapy is even. more effective. So, I guess I should preface this by saying. I don't believe that any of this stuff. should be placed on people without their. permission. So, I'm working I work in a healthcare. environment. So,

do I go and pray for people. who don't believe? No. This is something. that that always has to be done. it has to be asked permission. Do you think. >> Yeah. people who believe in God are. healthier generally? All other factors It would seem the data. would indicate that. people who. have a healthy relationship with their. church, who have a healthy relationship. in God, are associated with less. disease. Cuz from a causation point of.

view, you could say well Causation, yeah. So, this this is what we don't we. They probably have more friends. They. probably have Yeah. So, the question is. is whether or not people who are. healthier and have more friends are more. likely to be religious or is it the. other way around? And and sometimes it's. difficult to tell those things. But I imagine there's a great calming. force that comes from believing in a. higher power. Absolutely. And and the other thing that. the other thing that's interesting about. all of these like new start stuff is. when you look at other particular.

religions, how a lot of these things are actually. incorporate in this. Like for instance, the Hindus are very famous for getting. up in the morning and welcoming the sun. And we just talked about the benefits of. of sunlight. We didn't talk too much. about nutrition, but fasting is is an. important part of that and and and. Muslims are are obviously um. part of their religion is actually doing. fasting during Ramadan. So, religions. have a hot and cold practice as well, don't they? Yes, yeah. At least through. history. And on the flip side of that, I.

would say that it's also shown that if. you have a unhealthy relationship, like. if you have if you believe in a God who. is vindictive or who's out to get you or. who's going to do something to you. unless you do something else, that has. also been shown to be negatively. impactful. So, it depends on the relationship that. you've got. What do you see in your. practice? Because you said something. earlier that you you're often there at. the end of people's lives. Yeah. Uh some. unfortunately sometimes I'm the last. person they see. And and it's.

you start to realize that you cannot I. mean that death is inevitable. And all we do in medicine is delay the. inevitable. So, what we try to do. and um and and I have a colleague uh. who's very philosophical about this is. we try to make sure that when these. things happen that they happen with. dignity and we celebrate the person's. life and and making sure that it's done. in the way that they would want to have. it done. What do people say as they're.

about to die? People become very. it's very different uh for for different. people, but uh they can become very. circumspect and and uh. I've seen such such contrasts. People. are ready to go. People feel like. they've they've done what they've come. to do. And uh they don't want anything. further to do. Like we're we're there to. to to to to to delay death, right? We're. there to put them on a ventilator or to. give them this medication. And you would. be surprised people who are look, you.

know, relatively healthy, but and. something is happening that we could. easily correct. They're like, "No, I I. I don't want that. I I I choose not to. have that." And we have to respect. obviously what they. what they choose. Obviously, we have to. educate them to make sure that they're. making the right choice, but once once. they have given all the information. ultimately they're the one that makes. the decision. So, you see people choose. death. When we can intervene in artificial. ways, they would rather not have that. and they would choose death, yes. Are. there any particular cases that changed.

you? Yeah. Yeah, there's there's there's a case. that changed me. But not in the way that. we've just been talking about where it. was horrible. This is this is actually a. miracle. I've actually seen a miracle happen. And. for me it happened early in my training. So, it it it made me think twice about. being a prognosticating physician. A. prognosticating physician? >> Yeah, saying oh. you're never going to walk again or or. you've only got 2 years to live. I I I. must have missed that day in med school. I just didn't show up that day. This was.

a young guy. He was he had he had. testicular cancer. And he went to the operation. The. testicular cancer surgery was a success. Unfortunately, during the operation. something happened. He didn't get enough. oxygen to the brain and he came out of. the operation with with anoxic injury of. the brain. This guy must have been in his 20s. And. he had a young wife. Um and uh. I had come onto the rotation as a as a. as a as a resident. And uh.

we had attendings and you have to. realize in medicine you have attendings. above you and what they say is just, you. know, that's that's the word. That's. what happens and and the ICU attending. we were the ones that were sort of. taking care of the patient cuz he was on. a ventilator but there was the neuro. neurologist who looked at everything and. says, "Look, this guy is not waking up. He has severe anoxic brain injury. We've. looked at the scans. This is what's. going to happen.". And so um. everyday we'd round on this guy and he.

was just he was just a shaking mess. He. was just there and he was just kind of. shaking. His eyes were rolling. No. response. Nothing. And everyday his wife would come in. Young wife. And she uh. she just didn't believe that this guy. was going to be like this for the rest. of his life. He was going to wake up. eventually and so she he would she would. be at his bedside like attending to him. and making sure this that and the other. And even asking us to put, you know, some special concoction that she made at. home into his tube feeding so that this. could go and help him make him better.

And we would we would go along with her. but I was looking into my attendings and. they're like, "She's she does she. doesn't understand what's going on. She. doesn't understand that he's never going. to wake up.". So, this is this is what I'm seeing. Uh. one day she came in and she's and she. just had this. smile on her face. She was just uh so at. peace and a smile. And uh they they were. Hispanic couple, so we had to ask a. translator what was going on. And she. told us, she said, um. I had a dream last night.

I had a dream that he was going to come. home. And she was convinced. Just absolutely happy, beaming. And. we're like, man, this lady. is is crazy. She doesn't understand. what's going on. Well, days went on, weeks went on, and uh. one day uh and and where I was rounding, it was it's just in this round nursing. The nursing station's in the middle, and. the doors to the rooms are all around in. a periphery. And we were going around the circle. rounding on the patients, and I could. look in, and I saw him, and he was kind.

of shaking, but he was kind of opening. his eyes. And I said, he seems to be focusing a little bit. His eyes seem to be focusing a little. bit more than they would be. And he kind of I I just said, I just. kind of put my hand up like this, and I. just kind of. and sure enough, he put his hand up like this shaking. And he put it back down again. I'm like, what? >> at you. Yeah. What? And I said, let's go check this out again.

Long story short, took months, but that guy walked out of that. hospital. 6 months later, he and his wife came. back. Walked onto the unit like like there was. nothing wrong with the guy. And he gave us a big basket of flowers. to thank that unit for what they had. done for him. In my mind, I knew. that for most of that staff, for most of. that time, they the people were just going through. the motions. keeping him alive, cuz that's what she. wanted.

Obviously, when when there were signs. that this guy was recovering, it was it. was complete shift. People were amazed. And so, what that did to me in my career. was it made me think twice. Like, what why did this guy get better? Now, he was 22, he was young. And And. typically, if something like that is. going to happen, it's going to happen in. someone who's very young, whose mind is. plastic, who can who can survive that. type of a situation. But it really.

it was a miracle. I can't I can't say anything else. I. mean, it's not something that we would. know. All of the experts said that this. wasn't going to happen, but it happened. What do you think happened? I think he had a loving wife. who believed in him. And something happened outside of the. physical and the mental. Maybe the spiritual. I don't know. It happens. It's very rare. And when it. does happen, it happens in young people. That would be what the medical part of. my brain would say. But the other part of my brain says,

"You know what? I only know about 10%, maybe 5% of the world's knowl- No. World's knowledge? 1% of the world's. knowledge. Maybe I have 5 to 10% of all. of the medical knowledge in this world. And I would say probably the explanation. is somewhere in that other 80 to 90%. that I just don't know. I think what it taught me was is that we. have to be humble. about what it is that we know. There's things that we know we know, and. there's things that we don't know. that we don't know.

We talked a little bit about this. chemical earlier on, melatonin. Yeah. I. just wanted to close this off because I. had a question on it. Um a lot of people. take melatonin supplements. at night time to help them sleep. Yes. Good, bad, and different? I think it's good in certain situations. So, if you're having difficulty falling. asleep, a little tiny dose of melatonin, no more than 5 mg, can be actually very. beneficial. If you're wanting to shift. your circadian rhythm back instead of it. being pushed back, but you want it to be. advanced forward, melatonin can be very.

beneficial. It's very beneficial for jet. lag. It's also beneficial for a few. sleep diseases, but I would not. recommend routinely for no other reason. taking large doses of melatonin. What's. the trade-off? You said earlier on that everything has. side effects, right? And it impacts. another part of So, taking high doses of. melatonin can actually make you more. irritable. And have irritable? Irritable, yeah. >> In what regard? Just mentally irritable. Yeah. What does that look like? Things set you off,

um eat more easily. So, like a a mood. disorder? >> Yeah, absolutely. Anything else with. melatonin that you're aware of? Not that we have studies for. People. have concerns that sometimes taking too. much melatonin may actually affect the. melatonin secretion from the pineal. gland itself. I don't have evidence of. that as yet to see if that if that's. actually the case. Dr. Rogers, is there anything else that. we haven't discussed that we should have. discussed? We've discussed a lot. Um. I think I think putting it all together.

is. again, the links. And if we have those links, medications have their place, but the. way that they work is by breaking down. other parts of the chain to strengthen. the weak chain. That can have an effect, especially at the end of life if you. want to sustain life. But if you're. interested in longevity, if you're. interested in making and living the best. life, then you want to strengthen all of those. chains. And I believe the key to doing.

that is something called NewStart. We have a closing tradition on this. podcast where the last guest leaves a. question for the next guest not knowing. who they're leaving it for. And the. question that was left for you is what. is the area of your focus that you are. most dying to talk about which you are. almost never asked about? This book, the Bible. Uh which is my uh which is my tradition. Evidence for.

science. in the Bible. What do you mean? This we we what we've been talking about. is. the body. and the health of the body. Um I'd like to put to to the test some. of the statements in the Bible to see if. they work scientifically. Like turning water into wine? No, well, potentially. Uh that's a miracle. What I was referring to is is this. And. this is what I've actually done and it's.

actually quite interesting. Is uh you know, Paul, who is one of the. New Testament writers in the Bible, wrote to the Corinthians, "Don't you. don't you understand that your body. is the temple of the Holy Spirit?". I said, "That's that's a really. interesting statement.". How would he come to that conclusion? Like what does that mean, the temple of. the Holy Spirit? So, the only temple at that time was the. temple in Jerusalem where they would. have the sacrifices and things. So, what.

I did was I went back and this is and. this is answering the question is. I'm looking for evidence of scientific. truth. probably unknowingly. by some of the writers in the Bible to. see whether or not there is truth. Does. Does that make sense what I'm saying? So, if you look and most of Exodus 25. through 30. is this painstakingly detailed. description of the sanctuary that Moses. built in the wilderness that he.

supposedly he got from God. This is what. he says. So, here's a great way to see whether or. not this this all flashes out. Moses is. saying, "Here's the description of the. pattern that I got for the temple.". And Paul is saying, "Your body is a temple." So, here's my. hypothesis. If we look at the pattern in the temple, should it match. the human body that they had no. understanding of at the time that Paul. wrote this. I We didn't know about cells. until Van Leeuwenhoek in the 1600s. We.

didn't know about the circulation of the. heart. until the 1600s with um with. William Harvey, okay? Yet, if you look in the human body, you have. the blood system. You have blood. circulating around in the vascular. system. And then it And then it goes. into the interstitial fluid. And then the interstitial fluid then. goes to the cell, which is There's a. There's a There's a plasma membrane on. the cell that you can't penetrate. through, but unless you actually have. the proteins to go. And then it goes.

into the cell, which is a compartment. with two compartments within it, right? You got the cell and the nucleus, right? This is exactly the same structure that. Moses was given in in the wilderness. And And by the way, uh Hindu temples are. actually similarly designed. They're. sort of this three-part situation. So, you have this altar of sacrifice, which is where the blood is. That's That's the blood in the human. body. Next, you move to the laver,

which is this. container full of water. And that's the interstitial space after. you go from the blood into the. interstitial space. Any pharmacologist. will know that this is the exactly the. pattern that you move to. The next thing. that comes is this structure. that has a veil that you can't penetrate. through unless you you go through it. That's the cell cuz this this structure. is the building and it's got a room. within a room. And that's exactly what the cell is. The. cell is this nucleus surrounded by the. cytoplasm. Well, in this room that you.

go into it first, there's pieces of furniture in there. that are very similar to the types of. organelles that you see in the in the in. the cytoplasm of the cell. For instance, there's this seven-branch candlestick. that's in there that's burning olive oil. and producing energy. That's like beta. oxidation producing energy. That's. exactly what you see in the. mitochondria. But the final thing is you. move into the nucleus. And this temple. has something called the most holy place. where there's this altar of.

where there's this ark of the covenant. You've seen Indiana Jones, right? >> Yeah. And and the first Raiders of the. Lost Ark, there's this ark and you open. it up and this is where the two tablets. of stone, the 10 Commandments, rested. So, in. that area you have two tablets of stone. written by the hand of God. the code. of life. And according to Jewish and and. Christian belief that this is the law. and if you break the law that's how sin.

is and the consequences of sin is. disease and death. Well, when we get to the nucleus of the. human body. you have two strands of DNA. And on the strands of DNA is the code. The nucleotides of which is the code of. life. If you manipulate that code that. leads to mutations which leads to. disease and death. None of this was known until 1950 when. they discovered DNA. And yet.
