So far I play it by ear: I wear sunscreen when I go out any time before 330pm. I don't get sunburn this way, but it's really hard to tell if I'm damaging myself. I also migrated from center Italy to Canada, so my skin is a bit more resistant (Sicilian heritage), but it makes it way harder to figure out the balance, since the sun is still strong in the summer.
I've been living in Australia and New Zealand, and have been terrified of sun exposure - during peak times (summer mid-day) it's scary how quickly you can burn. However I also have low vitamin D. My current strategy is to check the UV levels (I've got a widget on my personal dashboard) and whenever the UV levels are moderate or below, I try to get as much sun exposure as possible - shorts and t-shirt, or topless. I t…
>due to constant exposure that part of my body is more resistant compared to the pasty areas. This is of course true, and it took me half a lifetime to realize I could get deep tans and stay out in the sun without any sunscreen, all it took was to "DCA" my way into sun exposure at the beginning of the summer. Concerted efforts to get 5, 10, 15, 20, 25, 30 minutes of unprotected sun exposure that slowly increase but n…

It goes against mainstream advice that no sun exposure is good exposure, and that getting a tan is not healthy. However I never "tan" my hands and they don't look any darker, but I've never burned them, even though they're the place that will get the most sunscreen rubbed off. Ditto for feet.
Yeah it does. But we are also here at this article.
This is not even remotely surprising to me. I've always been a bit skeptical of "the sun is evil" (and got even more skeptical when I was told I should wear sunblock inside!) and ensure I get 20 minutes full body exposure daily in the summer. Anecdotally, I can tell a general difference in my mood and sleep during periods where I get adequate sun vs. when I'm not (and I supplement vitamin D when I'm not). While I am…
But it is fairly intuitive that sunlight's ultraviolet radiation at any strength is going to degrade your skin over long periods of time.

Most western diets gets more than enough d-vitamin through food additives. Just a couple of slices of cheese per day and some milk is all the d-vit you need here apparently. The old folk saying is to take d-vitamin supplements in all months that has an R in them. Probably sound advice
The FDA recommendation for Vitamin D is off by a factor of 10 due to a math error, and it has never been corrected. https://www.sciencedaily.com/releases/2015/03/150317122458.h... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5541280/
2. while there's plenty of evidence that vitamin D levels is associated with positive health outcomes, AFAIK evidence that vitamin D supplementation being associated with positive outcomes isn't very good.
edit:
3. I dug further and found there was a response to the study that you linked[1]. The response points out that the standard used by the original study (ie. supplementation levels that's needed for 97.5% of the population to achieve adequate serum levels of vitamin D) would cause people on the lower end to consume too much. Therefore the recommendation of 8000 IU (or any single number, really) is bad, and we should instead have different recommendations according to body weight:
>With this approach we estimated, for example, that doses of 1885, 2802 and 6235 IU per day are required for normal weight, overweight and obese individuals respectively to achieve natural 25(OH)D concentrations (defined as 58 to 171 nmol/L).
As such, even though there might be an error caused by "off by a factor of 10", everyone really shouldn't be upping their supplementation by a factor of 10.
This is the key point to keep in mind; “The ‘Slip, Slap, Slop’ guidance is appropriate for the descendants of white-skinned north Europeans living in high-UV environments such as Australia, where they have a lot of skin cancer. But it is not appropriate for white-skinned Brits here in Scotland, and it is absolutely inappropriate for dark-skinned Brits, who have made the reverse migration from Africa or India,” says W…
And yet ... when it comes to sunblock ... I try to avoid sliding into a conspiratorial stance, but let's just say that I don't use it [0], and I am very curious about the reason(s) why so many of us do.
ps. yes, I do know about skin cancer and have several friends and family that experienced it.
[0] if am going to be outdoors all day after a long period of being mostly indoors, I'll use it for a few days to protect my nose, lips, cheeks, ears and neck. Then I'll stop. I prefer sunblocking sleeves for my arms if that sort of is necessary.

I'm glad I was forced to wear a helmet because otherwise my head would look weird ;)
I would like to think that I'm about as far a way from any sort of conspiracy theory as one could get. I have no time for anti-vax stuff, for example. A huge fan of "never blame on conspiracy what you can blame on stupidity". Etc. etc. And yet ... when it comes to sunblock ...

How are you still curious then?
