Near-infrared is mostly absorbed at the skin level and raises the skin temperature. We can't exactly perceive the deep heating effects of FIR, though, because our body's ability to sense heat is mainly at the skin level. Nonetheless, the effects of FIR rays promote bioprocesses such as increased metabolism and blood circulation, and can raise core body temperature. . . For many, the biggest news in FIR technology is its application in the evolving science of detoxification, and the device being used is the far-infrared sauna. But the detox application is health news that can benefit everyone. . .
Saunas also stimulate cells to release toxins which can then be eliminated by the liver and bowel.
Several published studies have now shown that this hyperthermic therapy can bring about the rapid removal of a wide range of toxic substances from the human body. Scientists are taking a serious look at hyperthermic therapy as a means to detoxify environmentally ill individuals. . . Since hyperthermic sauna therapy removes metal contaminants from the body by a different mechanism than chelation therapy we have found that it may be used to further the benefits derived from chelation therapy. And we have also found that it may be an alternative for those who are unable to undergo chelation. If we provide our bodies with a proper balance of anti-oxidants and other nutrients, we help prevent disease and also the aging process.
