Robert Fosbury is an astrophysicist and astronomer who has turned his expertise to understanding light:life interactions

I will be getting him back in my podcast to discuss fascinating astronomical phenomena as they relate to human health.

Check out the full episode at the bottom of the quoted note.

"There's a point I'd make about the ultraviolet and the vitamin D synthesis. It's always said that when the sun's below whatever the angle is, 45 degrees, you get precious little ultraviolet getting through. But the sunlight that's reaching the atmosphere above the ozone layer can readily scatter down onto you from above through the thinnest, the vertical path through the ozone layer.

"So the Scandinavians out on the sea ice skating for five hours a day, like one of my friends does, they get plenty of ultraviolet radiation, even with the sun on the horizon, because of scattering of sunlight down through the ozone layer.

"So there is a path for vitamin D-generating ultraviolet down through the sky, even in the winter with a low sun, if you're outside and you have at least part of your body uncovered." — Astrophysicist Robert Fosbury, PhD with Max Gulhane MD @ 01:38:38 – 01:39:42 https://youtu.be/ZnkQSjKwH-M&t=5918
