Scott Zimmerman: "One of the things I got in trouble for is that I kept on saying that if you look at just from the optics standpoint, the highest density of photons in the body, in the skin, is actually in the short-wave infrared, because there's such a strong absorption. That basically appears to be being used by the body to generate hydrogen peroxide, which is then used, it's in the outer 50 microns of the skin. And that hydrogen peroxide allows us to basically photobleach the outer portion of the skin to get a higher efficiency for UVB absorption, which then allows you to make cortisol, vitamin D, sex hormones and all these things.
"The main thing I keep on trying to say is don't discount even small areas of energy coming from the sun, because it may be doing something very unique in combination with other wavelengths. That's one of the reductionist problems. And Glenn's been really good about this in making these points, that unfortunately we tend to run reductionist-type experiments, where we look at one wavelength or one biomarker. And the body is having to do this all simultaneously where it's taking thousands of different variables going on, and it's optimized as best it could in sunlight to get the best results we can for survival.
"When you start talking about one wavelength or one biomarker, you end up basically missing the fact that you may be hurting something else.
"And one of the things that I got in trouble for was I kept on saying to the sunscreen people, the cosmetic people, what you're doing for someone who has very light skin may be helpful. I don't believe it, but it may be helpful. But mandating that to everybody, all the cosmetics to have SPF in them, hurts someone with dark skin, especially at higher latitudes. They're struggling to making vitamin D as it is, and you're now putting SPF on someone with very dark skin that has almost zero chance of getting melanoma and putting them at a disadvantage, in my opinion, compared to someone with lighter skin.
"It's a very complicated arrangement, the relationship between sunlight and biology."
