Sunlight: Optimize Health and Immunity (Light Therapy and Melatonin)
About this video
Dr. Roger Seheult of MedCram reviews the benefits of sunlight beyond vitamin D, covering the solar spectrum, circadian rhythm, melatonin and infrared light. The lecture runs nearly two hours with timestamps.

Try infrared light therapy. (sun, infrared heater or specialized light) We recently found out that all of our mitochondria in our cells need infrared light to get rid of oxidative stress. Our modern environment is devoid of infrared light: create all sort of inflammation and autoimmune diseases. I had similar symptoms(peripheral neuropathy, headache), heal myself and my eczema that I had every winter in the last 23 years with a few minutes per day in front of a infrared space heater.e It’s this doctor that gave me the idea to try it out. [VIDEO] I also know someone who was dying of IBS in the hospital, at some point he say f*ck it if I am going to die it will be under the sun. He checked out of the hospital, whent to mexico (from Canada) and healed himself without medication. I think a lot of our modern problems are caused by our environment (vit-d, infrared, and other things.) I hope people try it out and that it help someone. Check out the videos of Medcram, many research papers have been done on this.
Read original comment ↗Please, please, if you have IBS, Crohn or other immune disease try infrared light or better the sun. Especially if you spend a lot of time indoor (engineer) if you live in the north or if your condition get worse in the winter. I know someone who save his life that way. To me it clear up my winter eczema. We need infrared to get rid of inflammation. It’s scientifically proven, free, yet most people are not aware of it. [VIDEO]
Read original comment ↗Our body NEED infrared light. (real doctor research with scientific evidence) An interesting recent discovery is that our body need infrared radiation to function properly, not just UV light/vitamin D. I think that people living in the northern climate discovered/felt that it was better to be exposed to the radian heat of the fire in the winter. We recently (50-100) years have been getting rid of fireplaces and replaced with forced air and baseboard heater that probably generated a lot of health problem. A month ago I discovered this information, bought an small infrared heated and healed in 10 days the winter eczema I have been fighting for 25 years. source: [VIDEO] I hope this help somebody

Read original comment ↗We also need infrared light to be healthy, led lights have none. Recent research have shown that infrared light is needed for our mitochondria to work properly. I have cured my 20 year winter eczema in two weeks with a cheap infrared heater. [VIDEO]
Read original comment ↗The article makes no mention of Photobiomodulation (and there’s no mention in these comments at the time of writing). And that's odd. Because that's the HUGE idea here. Yes, there are concerns about the harms associated with the UV end of the spectrum. But there are also the massive benefits from the Near Infrared (NIR) end. Certain NIR wavelengths, around 810nm to 850nm, penetrate up to 5cm into the body and have a dramatically positive effect on mitochondria, creating the most powerful sub-cellular antioxidant (melatonin) to manage Oxidative Stress. This is well-established science now. Indeed, the exact mechanism is known (cytochrome c oxidase, etc). It turns out that for good health it helps to be exposed to the Sun (and specifically NIR). We're more plant than we realise (a different mechanism obviously). And, if you think about it, how on earth could we have not evolved to take advantage of the “free” energy provided by the Sun, particularly the NIR part of the spectrum which actually delivers about half of the energy. Here's an explanation from MedCram: [VIDEO]
Read original comment ↗There's an interesting theory about mitochondria and melatonin secretion caused by near-infrared light that may be causing the different health outcomes, which historically are correlated very strongly to Vitamin D serum levels (where causation has yet to be shown). Here's a link for a presentation and a proposed mechanism of action around near-IR light by one of the best sources of medical science info on the internet: [VIDEO]
Read original comment ↗It's surprising this article doesn't significantly mention sunlight's non-UV components, like infrared light. There appears to be increasing evidence to support its ability to influence various processes within the body to positive effect. MedCram has some easily digestible reviews on the topic: - The ability for light to influence glucose metabolism: [LINK] - Light's effect on immune response and other processes: [VIDEO]
