Using Light for Health
Blue light
In my conversation with Dr. Samer Hattar, a senior investigator and chief of the section on Light and Circadian Rhythms at the National Institutes of Mental Health (NIMH), he discussed the importance of viewing morning sunlight, specifically UVB rays, blue light, to improve mood, increase energy, regulate appetite and increase dopamine release. He also warned that UVB light exposure from artificial sources/screens at night (10 p.m.-4 a.m.) decreases dopamine levels and negatively impacts feelings of depression and anxiety. Once in a while is fine, but if you are looking at your phone or turning on bright lights, especially overhead lights, between 10 p.m. and 4 a.m. on a regular basis, your health will suffer.
Red light
“Red-light therapy” is becoming more common. It has, indeed, been shown to improve eyesight in individuals older than 40, but it must be done in the early daytime. It can also assist with acne, wound healing and more, but for all those effects one needs a special red light. They are commercially available but carry some cost (hundreds to thousands of dollars). That said, if you want to learn more, I discuss these and the science and tools in our episode titled “Using Light (Sunlight, Blue Light & Red Light) to Optimize Health.”
