Blood pressure is one of the biggest health threats in the western world, often called the “silent killer”, high blood pressure puts a strain on cardiovascular systems leading to higher risk of a heart attack or a stroke. It’s good news that an Australian study has concluded that heat therapy lowers blood pressure and improves blood vessel dilation (Experimental Physiology, June 2021). Earlier this year another study found that sauna use improves cardiovascular health in people with high stress jobs (International Journal of Environmental Research and Public Health, Jan. 27, 2021). Also it has been shown to help blood flow in people with stable coronary artery disease (Canadian Journal of Cardiology, March 2021). This builds on the famous JAMA study demonstrating the same thing.
