Saunas may improve mortality rates and blood pressure

Using a sauna for 19 minutes, four to seven times a week, can improve mortality. Dr. Azar explains that the heat helps blood vessels stay flexible, lowers blood pressure, and decreases inflammation, which is the body's process of fighting against harm. The longer and more often you use the sauna, the better the benefits. Cold plunges extend life in worms and rodents, but there is no human data yet. "What happens in an animal does not translate into what happens in humans." The heat has the proof that the ice lacks.
