The goal of every sauna session is to increase your core body temperature, so cover up your head with the Organic Sauna Hat. The head loses more heat than other parts of the body in an attempt to lower your temperature. Using the hat keeps the body from cooling off as fast, so you will sweat more in less time and experience greater detoxification and immune-boosting benefits. The hat also catches dripping sweat from getting into your eyes. Heat and hair do not mix! Regular saunas or exercises with near-infrared lights dry out the hair shaft, causing damage. Try a hot oil treatment on your hair during your sauna or exercise session. Just cover up and wear the soft, comfy, organic fleece sauna hat, and you'll look great.
