Unlike traditional saunas, which operate at extremely harsh temperatures, infrared is a gentle, soothing and therapeutic heat that promotes relaxation, detoxification, and improved sleep. The invisible light heats the body, instead of the surrounding air, allowing you to enjoy much longer and more comfortable sessions. The infrared sauna heat deeply penetrates tissues, joints and muscles to relieve anything from minor aches and pains to chronic pain conditions such as fibromyalgia. The penetration of the infrared sauna light induces a deep sweat to make the heart pump faster, which in turn increases blood flow, lowers blood pressure and improves circulation. Heating the muscles with infrared rays produces an increase in blood flow similar to that seen during exercise. Regular infrared sauna use – especially in the mid infrared range – can significantly stimulate blood flow up to twice the normal rate.
