In the high temperatures of a traditional or infrared sauna, skin heats up and core body temperature rises. In response to these increased heat levels, the blood vessels near the skin dilate and “cardiac output/circulation” increases. Medical research has told us that the heart rate can rise from 60-70 bpm (beats per minute) to 110-120 bpm in the sauna (140-150 bpm with more intensive bathing), and can often sink to below normal after the cooling off stage. Regular sauna usage has been shown to reduce the risk of all-cause mortality and fatal cardiac incidents along with reduced risk of stroke and hypertension.
