That's been my conclusion recently. While I'm sure it's true that people aren't getting enough vitamin D because they are indoors a lot, I'm not convinced you can't easily get enough of it in supplement form. If UV is only needed for vitamin D then you might as well avoid the aging effects of UV exposure and pop a pill.
- amanaplanacanal 10mo agoI don't think we know the entirety of what happens in the skin with UV exposure. We are pretty sure that vitamin D is good, and that cancer is bad, and that seems to be all that people talk about, but there are a lot more things happening that we don't fully understand. I suspect when we know more, the best answer is going to be moderation. But it's really anybody's guess right now.
- kelseyfrog 10mo agoThere are even things that we do know about but generally aren't talked about such as UV-triggered nitric oxide release[1] which moderates blood pressure among other positive effects. I want to be clear that there being pros and cons whose relative proportions change is very different than what some other commenters seem to be implying which is closer to a threshold model of UV safety which clearly doesn't exist and is non-scientific. 1. https://www.nature.com/articles/s41598-022-13399-4 https://www.nature.com/articles/s41598-022-13399-4
