The article seems to be a meta analysis of a bunch of conflicting research to support a narrative that we don’t really know shit. And fair, we don’t. But a couple of things we do know that weren’t covered - egregiously so - is that aging is UV damage. Sometimes called photoaging, wrinkles, sun spots, discoloration, fine lines, grey hair, all of that shit that you associate with someone visibly looking old is sun dama…

I've not heard that grey hair is sun damage.

Do you have any sources for that?

I don't know of anyone using sunscreen from the moment they wake up until they go to sleep. Guaranteed that even the best user will still receive a healthy amount of UV even if they refresh every few hours. As far as I'm concerned sunscreen is a 10am-5pm endeavor, not needed before or after

Worth noting here for any readers new to UV guidelines that the above rule isn’t necessarily helpful for you. I’m currently traveling in an area that is 8:30am-4:30pm and live in an area that’s 10-6 pm in the summer and shifts throughout the year. The actual rule is derived from your location’s safe UV index zones, which is found out by determining what local time the UV Index <= 2. Above 2, wear some amount of prote…

That's basically sun up to sun down, here.

It's been completely grey, overcast, and raining here all day and the UV index sat between 3 and 5.

There’s plenty, though please evaluate the veracity of their claims for yourself, I’m not a scientist nor do I excel at parsing scientific articles. Here’s one I’ve come across after a few minutes which references many others https://www.sciencedirect.com/science/article/abs/pii/S10111...

Ya, the relationship between UV and sunlight is strange and unintuitive. For that reason I use a UV widget on my lock screen.

I find that being exposed to the value (e.g. 4) while being able to see the suns effect (e.g. cloudy) gives me a better feel for conditions.
