The infrared sauna or infrared cabin is used to heat up the human body. It is advisable to undergo the treatment before sports, rehabilitation or regeneration activities. It involves the emission of infrared rays. The long-wave radiation penetrates deeper into the skin, from 4mm to 4cm. The muscles are relaxed and the body is not stressed. The infrared sauna has the energy set to match as closely as possible the energy radiating from the human body. Sweat production in the infrared sauna is up to three times higher than normal and at a temperature of 45 - 60°C.
