I wonder if it’s just correlation, with the actual cause of both being physical activity. Physical activity likely makes you go out into the sun more, and it also likely reduces mortality.

- maeil 2y agoOne of the things I love most about HN - you think of a hypothesis, and right after you see someone else who has already posted it. Very curious about this one as well. Though I don't imagine it being the "actual cause", just a big cofactor. I'd still put some money on the direct effect of sunlight absorption by your skin in itself having additional positive benefits (in appropriate doses).
