The principle is by electron impacting nanometer carbon,and then to induce heat-sensitive and the electrical sensitivity of the special natural ores, to produce health products with far infrared rays and negative ions，which is currently the only patented healthcare products with both of FIR and negative ions. Their fever principle is through FIR to stimulate human tissues for resonantly heating; the incidence of heat occurs from our body, not only accelerating the potential balance between the acupuncture points of the body, to promote blood and lymphatic circulation, to enhance metabolic functions in the body; and heat will deeply go into the body, then supplemented by negative ions to activate cells, combined with the effect of negative ions to achieve the purpose of dual health care, not just the heat of body surface of the general heating blanket; so it is suggested that you can long-term use to improve physical fitness, eliminate fatigue and enhance the vitality.
