lecture · intermediate · 2022–2024 on HN

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.

HN cites it as an accessible physician-led review supporting claims about infrared light, mitochondria and morning sun.

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. ▶ this video

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. ▶ this 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.

Whatever you do don't start taking Ambien / zolpidem. Solved nothing and now it's hard to quit. I recommend checking out ▶ this video TLDW sunlight in the morning good. link tldw: you may have apnea and not know it. Better to catch it early on.

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: ▶ this video

@beebmam2023-02 · in “Vitamin D serum levels, supplementation&suicide attempts&intentional self-harm”

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: ▶ this video
