alt Hacker NewsI live in the tropics and there is plenty of sunshine here. So my skin doctor told me to avoid the sun at all costs, always wear suncreen and a hat, don't go out in the daytime. A few years of that and now I have a vitamin D deficiency.

Reminder that the FDA recommended daily allowance of vitamin D is 10x lower than it was supposed to be, because of a math error, and they have never corrected it.
Here’s the American association of dermatology recommendation. They say don’t try to get your vitamin D from the sun. https://www.aad.org/media/stats-vitamin-d
I can’t really check for the studies right now since I’m on the phone, but I distinctly remember being interested in the theme of skin cancer due to personal reasons, and that studies found that great exposure to the sun, although slightly increasing the risk of benign skin cancer, does greatly decrease the incidence of non benign skin cancer.
Wearing sunscreen might be a good idea if you are white ethnicity (that is your ancestors lived in northern Europe for thousands of years).
For others. It depends.
Native South Americans, Africans and Indians seem to get skin cancer at much lower rates.
Yea sun damage and cancer vs. vitamin d deficiency is a little bit of a balancing act. It also doesn't help skin color is very critical part in all of this but people view that topic as taboo to discuss. The entire reason for skin color variations is a genetic optimization for UV absorption at specific latitudes vs sunburn risks.
That and the other half of the problem is we are all sedentary as hell in all latitudes these days. Be it people hiding under AC at the tropics or hiding in heated homes in the north. We don't go outside to get enough sunlight and our fat reserves that store vitamin d don't grow large enough because we still don't go outside when the weather is tolerable.
Unless you're non-native and have redhead-style very white skin or some history, the doctor sounds overly cautious to paranoid.
Hundreds of millions live in such climates (including people with fairer skin) and have no problems, even though they don't do anything extreme like "avoid the sun at all costs, always wear suncreen and a hat, don't go out in the daytime".
I'm white and I lived near the tropics for a few years, big white and asian population, everybody was out in the sun all the time, hardly covered too. Skin cancer stats as good as Europe or US.
