Cool white LEDs are the most disruptive to circadian and overall health. The 2007 energy bill will effectively ban warm white LEDs and require cool white LEDs in 2028. Scott Zimmerman's petition Dr. Alexis Cowan: "The other thing that I'll say just briefly is that like people will probably see if they're watching that I have like lights on in here. They're incandescent bulbs. And the ban on incandescent bulbs is not lifted. There's been like some kind of rumors online that with the new administration that that ban was lifted. It is not. There's actually petitions going around. One of them is led by Scott Zimmerman, who's a colleague of mine. […] "But the issue is a 2007 energy bill that sets the requirements for energy consumption per visible light exposed. And so essentially through that stringent guideline, they're going to be phasing out not only incandescent bulbs, but even warm white LEDs will not adhere to the stringent guideline. Virtually every public space you go in, if this ends up going through in 2028, will be cool white LEDs, which are the most disruptive to circadian health and overall health, so we need to make some progress on that front. If people want to learn more about that anyway, you can just give me a follow. I'll be posting about petitions and ways to kind of help counterbalance that."

Sunlight helps create nitric oxide release in our skin and arterials. Why are we pushing drugs like Viagra? People just need to go outside and take their clothes off and do sensible solar exposure Dr. Jack Kruse: "Nitric oxide was, you know, given the Nobel Prize in 1992. But you know what the problem is? Even to this very day, it's 2020 now, does everybody really understand what the implications of 1992 Nobel Prize was for clinical medicine? The answer is absolutely not. "Sunlight helps create nitric oxide release in our skin and arterials. Well once you know that, why are we pushing drugs like Viagra? Why are we pushing drugs that work on the nitric oxide renin-angiotensin system for Big Pharma? Why? Because you can patent it. You don't need a patent for sunlight. People just need to go outside and take their clothes off and do sensible solar exposure. The problem is what does Big Pharma and dermatologists and eye doctors tell you? There is no sensible solar exposure, because if you do go in the sun you're not going to need our solutions. That's the point. That's the point that the Regular Joe needs to get to. And what I just said right there, that's not controversial; that's blatantly obvious. It's medical fact. It's not opinion. It's not even hyperbole." Dr. Jack Kruse @ 04:29–05:37 (posted 2020-11-13)
Light impacts hunger. UVB light stimulates POMC production, creating α-MSH, thereby suppressing appetite. Modern humans don't get enough UVB light. GLP-1s, like Ozempic, stimulate POMC production in the hypothalamus to reduce appetite. You could have just gone outside and gotten the UVB light to get a very similar effect Shawn Stevenson: "Does a light impact our hunger?" Dr. Alexis Cowan: "Hugely, hugely, hugely. So, a lot of people think that hunger is a willpower issue. It is not. It is controlled by the brain through many complex mechanisms. But this is also why I really want to talk about UVB light because when we're exposed to UVB light, it creates a neurohormone in our brain and in our skin called POMC or proopiomelanocortin. So this is a complex prohormone that's cleaved into 10 different hormonal products. One of these products is α-MSH. So MSH stands for melanocyte-stimulating hormone. So, as the name implies, α-MSH is responsible, it's one of the factors responsible for telling melanocytes to turn on melanin production in response to UVB light. And so, that's one reason why you get a tan in response to the sun, because your melanocytes are getting the signal to, Hey, we need to make more melanin. And this is not only from a protection standpoint, but from an actual harnessing of the energetic capacity of UV light standpoint as well, which we can talk about in a bit when we're talking about melanin. "But with regards to hunger control, appetite and energy expenditure control, α-MSH also plays a very important role. So α-MSH actually binds in the hypothalamus of the brain, which is like the kind of the control center for metabolism, appetite, bioenergetics like it is the hub that is telling you when to eat, when not to eat, when to move, when not to move. And α-MSH, when it binds to receptors in the hypothalamus suppresses appetite and increases energy expenditure, which should sound like a holy grail with regards to the obesity epidemic and you know a lot of the issues that we have as a result of that diabetes, etc., because if you're getting that UVB light input, you're naturally going to want to eat less, and you're naturally going to not only want to move your body more and have more energy, but you're just going to burn more energy at rest through an elevation in your basal metabolic rate. "So this is just one factor from POMC that is having all these effects. We can talk about the others as well, but light plays an absolutely critical role in regulating appetite and energy expenditure. And when you learn that modern humans, especially in America, are spending over 90% of their time indoors not getting any of those UV rays, and when they are going outside, they're told to wear sunblock, sunglasses, protect themselves from the UVB light, then it makes so much sense that as a result of that, we are basically having a bioenergetic collapse and a lot of kind of a frayed system that is not able to regulate its appetite and energy expenditure effectively to yoke that to the environment. So it's a absolutely huge issue and a crux of the problem." Shawn Stevenson: "Wow. Oh my gosh. So it just makes sense with dysregulation and hunger and we jump to instead we're trying to treat the symptom with all these new innovations, GLP-1s, and the like." Dr. Alexis Cowan: "Well it's actually interesting but the GLP-1s, like Ozempic, work on this POMC pathway. They actually stimulate POMC production in the hypothalamus to reduce appetite, when you could have just gone outside and gotten the UVB light to get a very similar effect."
