Infrared Sauna While traditional saunas generate heat by circulating hot air, our 2 person far Infrared Sauna warms you directly and penetrates deeply in a gentle but effective manner. Infrared Saunas typically range from 110-140 degrees Fahrenheit and we set ours at ~135F. The supposed benefits of using an infrared sauna are similar to those experienced with a traditional sauna. These are said to include: better sleep, relaxation, detoxification, weight loss, relief from sore muscles, relief from joint pain such as arthritis, clear and tighter skin, improved circulation, and for people with chronic fatigue syndrome.
