Scandinavia sits at a high latittude with a low sun angle, yet the natives don’t seem to be vitamin D deprived or suffering unusually high Xi Virus death rates.
Supplementation may account for this discrepancy, but another factor could be the months-long snow cover that is common there. Snowburn is a real thing. Anyone who skis will tell you that the combination of the wind stripping off your skin’s natural oils and the reflection of the sun off the snow can cause some serious facial sunburn.
Scandinavians may be protected by higher vitamin D levels that are a consequence of their long period of snow cover reflecting the sun onto their exposed skin.
