Dr. Toshiko Yamazaki, MD owns an Far-infrared therapy clinic in Japan where she has done extensive research on the uses of Far Infrared Therapy or Infrared Light Therapy. In her book, "The Science of Far-Infrared Therapies," she explains that one of the reasons Far Infrared Therapy has beneficial results in a variety of illnesses is the ability of Far-infrared waves to remove toxins with mercury detoxification, which is often at the core of many health problems. Since humans are bio-accumulators, numerous toxins that disturb natural body healing and cannot be removed immediately after entry are stored in our bodies and prevent future natural body healing.

Infrared light is part of the Sun's invisible spectrum of light. The benefits of Far-infrared light are manifested in its ability to penetrate the human tissue.
