I've started to ignore studies these days that contradict how most humans would have lived, for most of humanity. Most humans would have had plenty of sun exposure and genetics would have adapted accordingly. I'll seek as much sun exposure I can on work days, but will never sun bathe for hours on end.

This is probably one of the worse heuristics I've ever heard.
Humans throughout humanity have lived awful lives full of disease, death, and misery. It used to be common for a woman to have 10 kids and maybe 2-3 would make it to adulthood.
The only reason you even have the ability to take such an obviously wrong position is BECAUSE of the very things you "ignore".
Exactly, a Northern European adapting to sun exposure doesn’t mean getting a tan, it would mean evolutionary pressure to adapt to, say, sunnier California via natural selection over a few thousand years where less sun fit portions die off earlier, while the surviving group slowly gets darker over many many generations or better at repairing damage.
If you’re fair skinned but find yourself outside the low UV region that your skin is adapted to, you are welcome to begin the new adaptation by avoiding sun protection and going outside without regard to the UV index.
I, however, will not join that genetic adaptation.
