Hypers have to hype to sell things (in this case, red LEDs), but the best photobiomodulation is available for free: go outside, close your eyes, and point your face at the sun. Your eyelids will screen out the harmful UV and blue light. Your eyes are transparent enough for the red light to reach your brain. Red light boosts our metabolism by refreshing the enzyme that has the red metal (copper). Cytochrome c oxidase [0] is "the last enzyme in the respiratory electron transport chain". [0] https://en.wikipedia.org/wiki/Cytochrome_c_oxidase https://en.wikipedia.org/wiki/Cytochrome_c_oxidase A submission from 1.5 years ago is about how morning exposure to deep red light improves eyesight: https://news.ycombinator.com/item?id=34609625 https://news.ycombinator.com/item?id=34609625 People who live in places where the sun goes away for the winter usually benefit from supplemental light provided by an electric sun. Incandescent heat lamp bulbs are an affordable source of red and infrared light. These bulbs have more of the red spectrum and less of the blue. From the submission: > PBM is thought to work through the mitochondria. Our cells—and those of animals, plants and fungi—contain tiny structures called mitochondria that generate the energy we need. Mitochondria have a chain of proteins that juggle electrons, and one of them, cytochrome c oxidase, contains heme and copper that absorb light, especially in the red and infrared part of the light spectrum. So, we shine one such light on living tissue, it gets absorbed by mitochondria’s cytochrome c oxidase, and what we get is a veritable biological domino effect that seemingly benefits every part of the organism.
