Infrared is the band of light we perceive as heat. Infrared rays heat your body without having to heat the air in-between.
Because infrared rays are part of sunlight, they are not only safe but also highly beneficial to our bodies on a cellular level. Health professionals have used infrared heat lamps for decades to treat muscle and joint problems. In hospital baby care units, incubators are often equipped with infrared heating systems to keep newborn babies warm.
Infrared saunas differ from traditional saunas in that they use infrared radiant energy to directly penetrate into the body's tissue to produce perspiration.
Traditional saunas use steam to heat the air inside the sauna, which then heats your body until you begin to perspire. In order for this to be effective, temperatures would need to reach in the upwards of 190 degrees F. Infrared saunas only need temperature of up to 120 degrees F to obtain the same effect. This lower temperature makes the environment more tolerable and allows you to breathe easier.
Over the last 25 years, Japanese & Chinese researchers and clinicians have completed extensive research on infrared treatments and their findings support the health benefits of infrared therapy as a method of healing.
