> A study published last year, for instance, examined medical data from 360,000 light-skinned Brits and found that greater exposure to UV radiation—either from living in Britain’s sunnier southern bits rather than the darker north, or from regularly using sunbeds—was correlated with either a 12% and 15% lower risk, respectively, of dying, even when the raised risk of skin cancer was taken into account.

Emphasis on “may” - this is hardly a gold standard study. Living in sunnier/warmer climates as a proxy for UV exposure as opposed to lifestyle differences afforded by such a climate, regional culture differences, etc. makes all of this very dubious to me.

I’m going to keep wearing my sunscreen most of the time when I need to be in direct sun, and continue regular screening for skin cancer.

I think it’s difficult to study this sort of thing because people and behavior is so different. I lost someone dear to me to melanoma and one of the things we learned was that a single blistering sunburn as a child increases cancer risk significantly. So small variations have big impacts.

I’d love to see a study where people wear a meter to sample exposure. My mom was an avid gardener who never wore sunscreen - she dressed appropriately with a hat.
