But basically your heart starts beating more blood starts circulating your vasculature changes shape literally to accommodate those increases in heart rate and blood volume and you're basically getting a cardiovascular workout in that hot environment even if you're just sitting down.
your your heart rate can go up to about 120 beats per minute some people can get it up a little bit higher ESP if they go in right after a workout but there's been head-to-head comparisons of moderate intensity exercise and sauna use and it's really like the the Studies have shown they're pretty comparable
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.
