Infrared saunas use infrared heaters to emit infrared light that is absorbed by the skin as radiant heat, unlike traditional saunas which heat the air. There are several health benefits to infrared sauna use such as detoxification through sweating, reduced pain and stiffness for arthritis patients, and increased heat tolerance compared to traditional saunas. The author recommends Heavenly Heat Infrared Saunas as they are made for the chemically sensitive and provide an ideal detoxifying environment through the use of untreated wood and ventilation systems.
