??Working Principle?: Far Infrared rays has the deep penetrating ability ability to penetrate, refract, radiate and reflect.FIR Can be absorbed.FIR transforms from light energy into heat energy. The thermal effect within the deep layers of the tissues causes blood vessels and capillaries to dilate, promoting better blood circulation, and the heat helps get rid of body toxins and metabolic. ??Great Effect?: Far-infrared tissue emits 9-14 µm far-infrared radiation, which can resonate with cells of the same frequency in the human body.
