Emits deep penetrating, far-infrared waves for most conditions; just aim the FIM Energizer at the affected area-bare skin, around 12-14 inches away. Leave it there for 30-60 minutes. The deep penetrating FIM energy will be felt as gentle warmth in the treated area. The emitted FIM energy penetrates up to 3½ inches, and stimulates microcirculation, delivering higher levels of oxygen and nutrients to the injured cells, while eliminating toxins and cellular waste. This begins the healing process as pain is relieved. How FIM Works.The FIM (Far Infrared Mineral) medical device features a plate coated with a mineral formation consisting of 33 elements, essential to the human body. The FIM (Far-Infrared Mineral) medical device features a plate coated with a mineral formation consisting of 33 elements, essential to the human body. When activated by its heating element, the mineral plate emits deep penetrating, far-infrared waves ranging from 2 to 25 microns in wavelength. This coincides with the natural, healing far-infrared waves generated by our own bodies, and is naturally absorbed into our tissues. At the molecular level, this exerts strong rotational and vibrational forces in the cells of these tissues. This absorbed energy has been found to yield many therapeutic effects on the human body by: Dilating blood vessels and increasing blood flow and oxygen saturation; Accelerating the decomposition of unstable cells; enhancing white blood cell function, increasing immune response; and stimulating the hypothalamus, which controls the production of neurochemicals, which control sleep, mood, pain, and blood pressure.
