A visit to the sauna is more than just relaxing; it seems to have real heart and cardiovascular benefits, as well. A group of researchers from the University of Eastern Finland—who previously found that people who regularly used saunas had
lower rates of hypertension,
cardiac death and
dementia compared to infrequent users—now find in a new study that sauna bathing can have a direct effect on blood pressure, heart rate and vascular health.
The team’s earlier studies on the health benefits of saunas, published in 2015 through 2017, were observational—meaning they could only find associations, and not cause-and-effect relationships, between sauna use and health outcomes. This time, however, the Finnish researchers recruited 102 people and monitored them immediately before and after a 30-minute sauna session to see what happened.
The sauna sessions also improved people’s vascular compliance: a measure of blood vessels’ ability to expand and contract with changing pressure. Their heart rates gradually increased during the sessions, as well, to an average of 120 beats per minute—about what would be expected during moderate-intensity exercise. (Normal resting heart rate is between 60 and 100.)
