Simply put, FIR - an infrared ray, is a form of light energy emitted from the Sun which we feel as heat. In fact, most of the Sun's energy is infrared rays and they are essential for all living things. Biowave FIR Sauna produces this same energy. Based on science, FIR technology was originally developed in the United States by the National Aeronautics and Space Administration (NASA), and later by Chinese and Japanese researchers. Thus, from a physics point of view, FIR is a transverse wave which is a component of the electromagnetic spectrum, FIR rays are also called 'vital rays' because of their regenerative effect on the body.
What Can FIR Do For The Body?
FIR rays penetrate approximately 1.5" into the skin and this light energy transforms to heat energy. This causes blood vessels to dilate, which promotes better blood circulation as the heat rids the body of toxins through sweating. Good circulation of blood and bodily fluids enhances the distribution of oxygen and ingestion of nutrients to every part of the body.
