- Sauna bathers are at a lower risk for elevated blood pressure, finds a new study
- The risk of hypertension lowered by 46% in men who had a sauna 4-7 times a week
- Sauna bathing may also lower systemic blood pressure due to overall relaxation of the body and mind
The Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) involved 1,621 middle-aged men living in the eastern part of Finland. Study participants without elevated blood pressure of over 140/90 mmHg or with diagnosed hypertension at the study baseline were included in this long-term follow-up study.
Based on their sauna bathing habits, men were divided into three sauna frequency groups: those taking a sauna once a week, 2-3 times a week, or 4-7 times a week.
During an average follow-up of 22 years, 15.5% of the men developed clinically defined hypertension. The risk of hypertension was 24% decreased among men with a sauna frequency of 2-3 times a week, and 46% lowered among men who had a sauna 4-7 times a week.
How Sauna can Help Lower Elevated Blood Pressure?
- During sauna bathing, the body temperature may rise to 2 °C degrees, causing vessels vasodilation.
- Regular sauna bathing improves endothelial function, i.e., the function of the inside layer of blood vessels, which has beneficial effects on systemic blood pressure.
- Sweating, in turn, removes fluid from the body, which is a contributing factor to decreased blood pressure levels. Additionally, sauna bathing may also lower systemic blood pressure due to overall relaxation of the body and mind.
