I really appreciate learning this fact, but I can't tell how it makes the quoted sentence misleading. The author is just talking about the surprising disparity between how warm it feels and how fast you will burn. They don't mention vitamin D.
replyI know they don’t mention vitamin D, but I think it’s important for people to know the context and not think that late day sunlight automatically = better
replyOhh, I see. I'm not sure it was "very misleading", but I agree somebody trying to decide when to get sunlight for the purposes of vitamin D could easily misapply the lesson from this article.
replyThat's good to know as an additional factor to consider, but it's not enough to justify your accusation that the original statement is "misleading".
replyYou're allowed to just say "cool, here's another important thing to think about it". You don't have to pick a fight.
I think the original statement was misleading wrt sunburn for the reason I stated. I think we have different definitions of fight.
replyThe statement you quoted is very useful [One of the most useful heuristics], and your statement is misleading. You accumulate damage (Photoaging, cancer risk) dramatically faster at high sun angles (i.e. mid day, close to the summer solstice, closer-to-equatorial latitudes) etc than low ones.
replyI am not trying to be negative, but this is very important if you have pale skin. Being outdoors in morning and late afternoon is dramatically less damaging than mid day.
It kind of depends on context.
replyIf your goal is "hang out in the sun but don't get burned", then morning/evening is better. If your goal is "get exactly as much vitamin D as I need while minimizing UV damage, perhaps using a timer", then it sounds like technically mid-day is better (assuming I'm reading the parent right).
it really only takes about 5 minutes of exposure to get the vitamin D your body needs. i would happily do it between 7-9AM when the UV is low than doing it at mid day.
replyYou only need 5 minutes at midday in the summer. At 7am, you get essentially no vitamin D.
replyIsn't think only true if getting enough vitamin D is as important to you as cancer?
replySunlight is associated with lower risk of almost every cancer except skin cancer, and skin cancer is the easiest to detect early.
