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

There's likely a "sweet spot" for sauna temperature where dementia protection is maximized.
However, that study looked at temperature. So they they they basically looked at different types of temperatures that people were using and they found something very interesting and that is is that when people started to go to the really extreme hot level, so they were going above 200° Fahrenheit, they were getting like 200 to 210 212° Fahrenheit that sort of like that go hard go home mentality. They actually had a higher two times higher risk of Alzheimer's disease.
4–7 sauna sessions per week, 20 minutes at 80°C+, reduce cardiovascular mortality risk by 40% over a decade.
Regular sauna use raises BDNF and improves verbal memory in older adults.
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.
