Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

Now, anytime you're going to increase temperature of yourself or anyone else or an animal, it is risky. I want to be really clear about this. Not everyone should engage in the behaviors I'm about to describe.

And people can die from hyperthermia.
4–7 sauna sessions per week, 20 minutes at 80°C+, reduce cardiovascular mortality risk by 40% over a decade.

Sauna protocols only generate the longevity effect when sessions exceed 30 minutes.
Hot-tub bathing yields cardiovascular benefits comparable to traditional Finnish sauna at matched core-temp dose.
