| Infrared ray is a band of light we can’t see with the naked eye, but we can feel this type of light in the form of heat, the heat we feel is completely healthy, safe and essential for all living things. |
| Unlike ultraviolet and visible rays, infrared rays tend to penetrate any medium rather easily because of their large wavelengths. This also means that infrared rays are not refracted much at all when passing from one medium to another. Infrared heats your body without having to heat the air in between throughout a process called conversion. The infrared is divided into 3 segments by wavelengths, measured in microns; 0.76~1.5 microns-near;1.5~5.6 microns-middle;5.6~1000 microns-far infrared. Among these segments, only far infrared penetrates organic substances such as human body two to three inches so that the warming effect is very uniform. |
