The benefits of sauna<\/h1>\n \n

Regular sauna use has some of the strongest long-term research of any wellness habit. Here is what that research shows, what it does not, and how to get the most from your own sauna.<\/p><\/div>\n \n

The science<\/p>\n \n

What heat does to your body<\/h2>\n <\/div>\n\n

Step into a traditional sauna and your body starts working to stay cool. Blood vessels in your skin widen, your heart beats faster to move blood to the surface, and you begin to sweat.<\/p>

During a session, heart rate and blood pressure rise much as they do during moderate exercise. One study put the load on the heart at roughly the level of steady cycling (Ketelhut and Ketelhut, 2019). Afterwards, blood pressure settles below where it started. In a Finnish study of 102 adults, a single 30 minute session at 73\u00b0C lowered average blood pressure from 137\/82 to 130\/75 mmHg and made arteries less stiff (Laukkanen T. et al., 2018).<\/p>

Repeat that a few times a week for years and the effects appear to add up. Most of what we know comes from one long-running Finnish study, which has followed the same group of people since the 1980s.<\/p><\/div>\n \n <\/div>\n <\/div>\n<\/section>\n\n\n

\n ›<\/span> About these figures<\/summary>\n

*All four figures come from the Kuopio Ischaemic Heart Disease (KIHD) study at the University of Eastern Finland. They compare people who used a sauna 4 to 7 times a week with people who used one once a week, over follow-up periods of 15 to 25 years. The heart, blood pressure and dementia figures are from middle-aged men (Laukkanen T. et al., 2015 and 2017; Zaccardi et al., 2017). The stroke figure is from a group of men and women aged 53 to 74 (Kunutsor et al., 2018). These are observational studies. They show a strong link, not proof that the sauna caused the difference, and they are no substitute for medical advice.<\/p><\/div>\n <\/details>\n \n <\/div>\n\n<\/section>\n\n\n

Lower blood pressure, healthier arteries<\/h3>\n \n

In the Finnish study, men who used a sauna 4 to 7 times a week had a 63% lower risk of sudden cardiac death than men who went once a week. They also had lower rates of fatal heart disease. A separate analysis found a 46% lower risk of developing high blood pressure. Longer sessions mattered too. Sessions of more than 19 minutes were linked with a lower risk of sudden cardiac death than sessions under 11 minutes. Researchers think the repeated rise in heart rate and the widening of blood vessels act as a gentle form of conditioning for the cardiovascular system.<\/p><\/div>\n <\/div>\n\n <\/div>\n

Lower risk of dementia and stroke<\/h3>\n \n

The same Finnish men who used a sauna most often had a 66% lower risk of dementia and a 65% lower risk of Alzheimer’s disease. A later study, which included women, found a 61% lower risk of stroke at 4 to 7 sessions a week. Better blood pressure and blood vessel health are the most likely link, since both protect the brain as well as the heart.<\/p><\/div>\n <\/div>\n\n <\/div>\n

Recovery and training<\/p>\n \n

Heat after exercise<\/h3>\n \n

A sauna after training is a long-standing habit for athletes, and there is some evidence behind it. In a small study of six runners, three weeks of post-training sauna sessions raised plasma volume by 7% and extended how long they could run before exhaustion. That works out at roughly a 2% gain in a race. It is a promising result, not a guarantee. Our guides to sauna before and after workouts<\/a> and sauna and cold plunge<\/a> cover how to fit heat around training.<\/p><\/div>\n <\/div>\n\n <\/div>\n \n <\/div>\n<\/section>\n\n\n
