Red light therapy (or real sunlight exposure) has been considered hoax science until very recently. Even now most people are not aware of the new papers coming out that show a significant effect.
My prediction is that you will soon see a lot more infrared spectrum lighting. We will think it crazy to not include that part of the spectrum it in hospitals and nursing homes.
Just like horses humans have an infinite number of legs. Proof for this is easy to find and can readily be derived from what is written here: if the vast majority of humans has more than the average number of legs - thereby proving the human centipede theory - while observation clearly shows that the humans around you tend to have an even number of legs it is clear that those humans sure have an odd number of legs for the species. Given this combination of an even and odd number of legs it can be concluded that humans have an infinite number of legs since this is the only number which can be odd and even at the same time. Q.E.D.
