UV exposure patterns have changed significantly. Long-distance vacation travel to sunny locations is much more common now. Tanning beds are much more common. Both holidays and deliberate tanning often take people from indoor office life to the opposite extreme of sun exposure.
People also dress differently in the sun than they did in the past. Even in my old family photos, it's interesting to see people relatively more covered up in the sun (long pants, long sleeves, big hats) in older photos relative to our modern shorts and t-shirt style today.
Some of this can be seen in statistics where melanoma rates on the torso are increasing much faster than average.
It's also theorized that people who wear sunscreen become more cavalier about sun exposure in general. Sunscreen doesn't provide perfect protection and it needs to be reapplied over time. A lot of people put some sunscreen on and then assume they're good for the rest of the day, or they wash a lot of it off in the pool, or they miss spots, and so on.

- Wowfunhappy 4y agoI don't think that contradicts the GP? They were giving possible explanations as to why skin cancer rates may have increased despite the widespread availability of sunscreen.
- melissalobos 4y agoSure and I was positing why they may have increased.
- Zhenya 4y agoBy enough to make people change their dress significantly? Could you provide some proof of such temperature changes?
- m463 4y ago> Tanning beds are much more common. I think they were common, say 80's/90's, but I don't see them much anymore. I remember meeting a woman once - early 20's and very attractive - except her skin was extremely wrinkled. She told me her parents had owned a tanning salon and she used it all the time. and a bit later that's how things ended up.
- light_hue_1 4y ago> I think they were common, say 80's/90's, but I don't see them much anymore. I think you might just have aged out of the group that uses them. Young people tend to use them a lot. Something like 1 in 5 people in their 20s have used one in the past year in many western countries. The statistics are pretty horrific. Looks like you're increasing your lifetime risk of skin cancer by a good 20% by doing this.
- Semaphor 4y agoWhere are those statistics from? I was wondering because using a tanning bed has always been a low-class thing and something to be ridiculed when I was in my early 20ies (I’m 36). German Wikipedia [0] has it at its highest 80ies/90ies, the stats they mention are for 14-45 year olds: 2012: 14.6 %; 2015: 11 %; 2018: 8.8 % [0]: https://de.wikipedia.org/wiki/Solarium https://de.wikipedia.org/wiki/Solarium
- yakak 4y agoIn the english version, there's a study of the average over multiple anglo and European countries, perhaps Germany was significantly lower than the average: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4117411/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4117411/
- Semaphor 4y agoYeah, but that stops with 2012 data, and for "last-year-exposure" the data is actually pretty thin for university students and adolescents: https://i.imgur.com/1Xly88x.png https://i.imgur.com/1Xly88x.png (Supplement, eFigure)
