Far Infrared Therapy utilizes light wavelengths below the frequency of visible red light. Though the light is not visible to the human eye, it can be felt as heat. Used in radiant heating units in homes, Far Infrared (FIR) penetrates below the skin and can be used as a medical therapy.
Medical Uses of Far Infrared Therapy
FIR therapy is light or heat therapy that has been found to increase blood flow and white blood cell function. FIR light helps remove toxins from the body and speeds the healing of tissues. FIR increases the metabolic rate and stimulates the hypothalamus. The FDA has approved far infrared lights to warm newborn infants in hospitals.
