Types of Saunas

Infrared lamp saunas use incandescent infrared heat lamps for heating. They emit mainly near infrared, some middle infrared and perhaps a tiny amount of far infrared energy. They also emit a small amount of red, orange and yellow visible light, providing warming and stimulating color therapy. These colors may assist the eliminative organs.
Far infrared saunas use ceramic or metallic elements for heating that mainly emit in the far infrared range.
Conventional saunas may be electric or wood fired and usually include rocks, which may have water thrown on them to create steam.
Most saunas are made from wood.
