Far infrared rays are a kind of electromagnetic waves, which are in the range of 3 to 1,000 μm in the wavelength range of the electromagnetic waves, and appear in the outside of the red line of visible light in the color array generated when light passes through the prism, and are radiations having stronger heat action than visible light. The order of the wavelength range is divided into near infrared, intermediate infrared, and far infrared, and far infrared has stronger property of heating organic material than near infrared, and it is widely used in the treatment and industrial field of human body. Far infrared rays in the 6 to 14㎛ wavelength range of the far infrared wavelength range is known to be the most beneficial to our life.

The human body is composed of about 60% of water, proteins, fats, carbohydrates, minerals, hormones, enzymes, and neural tissues. Far-infrared rays generate heat energy in the process of cellular activity by activating these substances at the molecular level, and this heat has the effect of releasing harmful substances (waste and heavy metals) accumulated in the body by activating all activities in the human body. That is, when the far infrared light is illuminated, the far infrared rays having the same frequency as the vibrations inherent in various atoms and atomic groups in the human body cause resonance.
