The dry sauna can also be an infrared sauna. Also known as FIR, it heats your body without heating the air around you similar to the way the sun utilizes the wavelengths of light for heat. It is a more efficient use of energy (healthy for your power bill) and very "hot" in the new home market. The infrared sauna’s heat source warms ceramic tiles in the wall of the sauna that make for an even heat without the need for a fan. They use less power, lower temps, heat faster with less maintenance than the standard dry sauna that depends on a floor heater and rocks for heat generation.
Infrared saunas can warm your deepest tissues and help heal. An infrared sauna is healthy for the whole family, including anyone with respiratory problems. Another perk of the infrared sauna is its control…you can set the time and temperature of the unit for what is best for you. Any time there is a spike in temperature the unit will shut down as well. Add in the other benefits of the dry sauna, including the expansion of blood vessels and raising your internal temperature high enough (110 degrees F) to burn fat, you may want to investigate the infrared sauna.
