A sauna is, essentially, a steam room. Installing a sauna in your home can provide you with a place to relax. The steam therapy from a sauna can also help treat a number of health concerns, including arthritis. Traditional saunas are constructed of hardwood. They supply dry heat by heating stones slowly over a wood-burning fire. Steam saunas, or steam rooms, are constructed out of ceramic tile. They use steam to provide wet heat therapy. A variation of these - the Turkish steam sauna - alternates heat and cold therapy because occupants splash their face with cold water from inside the sauna. An infrared sauna provides dry heat through the use of infrared lights mounted on the ceiling or within the sauna benches. Infrared saunas heat the body, but the room remains comfortable.
