Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
I do want to provide a cautionary note that if you are already running a fever, getting into a sauna could take your body temperature into dangerously high levels, dangerously meaning you can kill neurons. And once you kill neurons, they do not come back.
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.
