That does seem to be the case. The Lindqvist study specifically said that sun avoidance was as bad as smoking iirc. Sun exposure has been one of my main activities for over 10 years. The evidence is now overwhelming.
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.
