The carbon fiber far-infrared heating film used can emit far-infrared light waves that have been translated as "light of life." The wavelength of the light wave is 8 to 15 microns. Modern medical science shows that 8-15 micron far-infrared rays are carefully approximated by the frequency of the human body's cells. After the "life light wave" seeps into the body, it causes the resonance of the cell's atoms and molecules through the resonance. The effect is that energy is absorbed by the human body, which causes heat reflection between the molecules, promotes deep subcutaneous temperature rise, expands microvessels, accelerates blood circulation, helps remove vascular contaminants and harmful substances in the body, and eliminates impediments to metabolism. Rejuvenate the organization, promote the production of enzymes, and activate the tissue cells to strengthen the immune system. Far-infrared light waves are used to relieve pain and assist in the treatment of multiple clock diseases caused by disorders of blood circulation and microcirculation, such as rheumatism, arthritis, frozen shoulder, cervical spondylitis, low back pain, back pain, and numbness of hands and feet.
