Infrared sauna

Common card · No. 367242

An infrared sauna uses infrared heaters to emit infrared light experienced as radiant heat which is absorbed by the surface of the skin. Infrared saunas are popular in alternative therapies, where they are claimed to help with a number of medical issues including autism, cancer, and COVID-19, but these claims are entirely pseudoscientific. Traditional saunas differ from infrared saunas in that they heat the body primarily by conduction and convection from the heated air and by radiation of the heated surfaces in the sauna room whereas infrared saunas primarily use just radiation. Infrared saunas are also used in Infrared Therapy and Waon Therapy; while there is a small amount of preliminary evidence that these therapies correlate with a number of benefits, including reduced blood pressure, increased heart rate and increased left ventricular function, there are several problems with linking this evidence to alleged health benefits.
