Far Infrared (FIR) heat is a form of light energy that can be very beneficial to the human body. Infrared rays fall just beyond the red light spectrum, but due to its longer wavelengths, human eyes cannot see FIR heat. Far Infrared heat has the ability to penetrate, refract, radiate and, reflect. The human body can absorb FIR because of its deep penetrating properties. When FIR penetrates through the skin to the deeper tissues, it transforms from light energy into heat energy. The thermal effect within the deep layers of tissues cause blood vessels to dilate, promoting increased blood flow. The heat produced helps to eliminate body toxins and metabolic wastes through perspiration.
