Regular sauna use has been linked to several heart health benefits, including improved circulation, lower blood pressure, and a reduced risk of cardiovascular events. The heat causes the blood vessels to dilate, which increases blood flow and helps reduce vascular resistance, similar to the effects of moderate aerobic exercise. This improved circulation can ease the work load on the heart and contribute to overall cardiovascular function. A major Finnish study published in JAMA Internal Medicine (2015) followed over 2,300 men for 20 years and found that those who used a sauna 4 to 7 times per week had a 50% lower risk of dying from cardiovascular disease and a 62% lower risk of stroke, compared to those who used a sauna only once per week. The study also showed that frequent sauna users had significantly lower blood pressure levels over time. These findings suggest that regular sauna sessions can be a valuable part of a heart-healthy lifestyle, offering both immediate relaxation and long-term protection against heart-related issues.
