Sunscreen and Sensible Sun: Never Burn, Prefer Mineral, Don't Fear the Sun

Summary

The "wear chemical sunscreen every day" message is a defensible core (never burn) that's been **over-generalised**: the recovery-posture position is **never burn, prefer mineral filters (zinc oxide / titanium dioxide), get regular non-burning sun** for its real circadian/mood/cardiovascular benefits, and **reserve heavy daily high-SPF for genuine high-UV, prolonged-exposure, or high-risk situations** — because chemical filters do absorb into the bloodstream, a vitamin-D pill doesn't replace sunlight, and avoiding the sun entirely carries its own mortality cost.
