Many – if not most – of us do not actively sweat on a daily basis. Deep sweating, however, has multiple proven health benefits. Benefits derived from a deep sweat can be achieved via regular sauna bathing.Due to the heat of a sauna, the core body temperature begins to rise. The blood vessels then dilate, causing increased blood flow (see above). As heat from the blood begins to move toward the skin’s surface, the body’s nervous system then sends signals to the millions of sweat glands that cover the human body. As the sweat glands become stimulated, they produce sweat. Sweat production is primarily designed to cool the body, and is composed of 99% water. However, deep sweating in a sauna can help reduce levels of lead, copper, zinc, nickel, mercury and chemical – which are all toxins commonly absorbed just from interacting with our daily environments.There is no shortage of books from Doctors and practitioners, who describe the benefits of detoxifying our bodies regularly. As many doctors will agree, a big reason for the popularity of saunas is that they are one of the best ways to detoxify our bodies.
