Far, middle, and near-infrared wavelengths are all part of the broad infrared healing wavelength spectrum and are responsible for the benefits people experience from infrared saunas. These wavelengths penetrate soft tissue up to an inch and a half, warming the body and opening blood vessels in a process called “vasodilation.” The result is increased blood circulation and stimulated sweat glands, delivering oxygen-rich blood to tissues and removing toxins from the body. Infrared saunas offer many benefits, including detoxification, stress and fatigue relief, muscle/joint pain relief, weight loss/calorie burning, improved immune system, increased metabolism, improved skin health, and improved heart health.
