Infrared saunas operate on the principle of radiant heat, a form of energy that warms objects directly without having to heat the air in between.
The term "infrared" refers to non-ionizing radiation, which is different from potentially harmful ionizing radiation such as X-rays. Infrared radiation is generally considered safe for the human body and is used to provide a soothing, warm experience.
Unlike traditional saunas that heat the air with steam or dry heat, infrared saunas use infrared light waves to warm the body directly. These waves penetrate the skin and muscles, potentially helping with comfort and relaxation.
Infrared saunas are typically set at lower ambient temperatures, usually between 48.8-65.5 degrees Celsius, compared to traditional saunas, which can reach up to 90.5 degrees Celsius. This may make infrared saunas a more comfortable option for some users.
