This isn't really about it feeling good or bad, rather it's about the effect of sunlight in significantly reducing mortality.

I agree that strong sunlight on a hot day doesn't feel good.

I'm not sure that's true over the very long run.

We're talking about a proscribed health practice that results in continuing discomfort and sickness. Even if the benefit manifests as predicted, I'm skeptical it can make up for the low quality of life.

edit: I'm far from alone in this. When I share my aversion to sunlight, I find many more folks who feel similarly, than I do people who are puzzled by it.
