Sunlight is a source of red light, near-infrared, and infrared light for improving mitochondrial function, eye health, and metabolism.

“infrared light helps the mitochondria and the fact that the mitochondria is at the sort of the core of all of these chronic diseases that we're battling it it it really wakes you up and you start to realize that maybe the lowest hanging fruit that we can do right now today for literally no money is simply to just work on getting more sun exposure in the winter time”

“The best source of red light, as well as the other longer wavelengths of light, such as near-infrared and infrared light to benefit your mitochondria by getting it onto as much of your skin or body surface as possible in a culturally appropriate way, as well as for eye health, as well as for metabolism, et cetera, is sunlight.”
