Infrared Saunas are an integrated, multi-functional facility for personal medical and recreational use which incorporates the advantages of both a sunlight bath and sauna all in one. The wavelength of far infrared ray is 5.6-15mm which makes it easily absorbable into the body. It can penetrate 40mm deep into the skin which makes cell tissues resonant, accelerates blood circulation and eliminates impurities, resulting in positive bio-thermal and physical effects.
