How Exactly Does an Infrared Sauna Work?
Unlike traditional saunas that heat the air inside the sauna and use steam to get the temperature of the sauna even higher, infrared saunas use a safe form of radiation, called infrared rays, to directly heat your body. The air inside an infrared sauna will heat up as a by-product of the heat created by the infrared rays, but the air temperature maxes out around 130 or 140 degrees, where a traditional sauna will go up above 200 degrees.
Although the word radiation sounds kind of scary, infrared rays are totally safe, and are actually the same type of rays that the sun emits. Think of standing in the sun on a cold, crisp day. You can feel the sun's warmth although the actual air temperature may be really cold. That's certainly the case here in Sun Valley!
