What Is Far Infrared (FIR) Energy?
Far Infrared Ray (FIR) is a form of light energy form the sun. It falls within the same family of infrared rays in the light spectrum, but due to its longer wavelengths, just like ultraviolet rays, human eyes cannot see FIR. Among the total spectrum of solar rays coming from the sun, the FIR waves are the safest and most beneficial. The energy is essential & beneficial for all human beings. FIR has the ability to penetrate, refract, radiate & reflect. The human body can absorb FIR because of its deep penetrating ability. There is more water inside of our body than on the skin surface; therefore, FIR waves can deeply penetrate the body (about 2 to 4 inches). The far infrared rays (which have a wavelength of 4-14 microns) are much safer, and have excellent healing effects on our cells. The FIR energy penetrates into our body and heats up from the inside. Heat is spread outwards by conduction in bones, convection in tissues fluids. The growing warmth (conduction and convection) dilates bl
