Our skin cells are designed to manufacture Vitamin D when exposed to UVB rays from sunlight. It actually doesn't take much time, as little as ten minutes exposure without sunscreen for a fair skinned person. I found this interesting article from about seven years ago. As with most warnings, it appears possible the concept of any amount of sunlight being bad for us was exaggerated. It reminds me of when fat, all fat, was considered deadly.
"Do you think the United States and other western countries have gone too far in promoting protection from the sun?
Possibly. Sun protection messages arose in response to rapidly increasing rates of skin cancers, and they were an essential public-health message. But we now recognize that some sun exposure is important for health, at the very least, to maintain healthful vitamin D levels. (Sunscreen blocks out nearly all UV radiation.) Taking this into account, the Cancer Council of Australia has eased its sun protection message a little over the last few years and now recommends that if you're out in the sun for relatively short periods, with a UV index less than 3, which indicates a moderate amount of UV rays hitting your area on a given day, then sunscreen and other sun protection (like hats and protective clothing) are not required. Beyond this, I believe we all need a little unprotected time in the sun during the middle hours of the day when the sun is at its highest and UV-B rays can penetrate the atmosphere."

Equal rights for others does not mean fewer rights for you. It's not pie.

Never try to teach a pig to sing. It's a waste of your time and it really annoys the pig.
