Beyond its relaxing and cultural value, sauna bathing offers a wide range of science-backed health benefits that contribute to physical and mental well-being. One of the most well-documented benefits is improved cardiovascular health. When exposed to high temperatures in a sauna, the body’s blood vessels dilate, increasing blood flow and reducing blood pressure. Regular sauna use has been linked to a lower risk of heart disease, stroke, and hypertension, as it helps to improve the elasticity of blood vessels and reduce inflammation.
