Two things can be true.

The study says sun good. But the studies being described in the UV are specifically comparing people who stay indoors vs people who get exposed to UV by being outdoors. The studies listed are not looking at application of sunscreen, or wearing clothes to block UV, etc.

This generally makes sense; stop being cooped up indoors and do things outside, but also wear UV protection.

Thank you, this is a much better comment than my original one, but this was exactly my point. Go outside more. Sunscreen probably isn’t killing you.
