Daiugin is a patented product of Japan that releases 4-16 microns of far-infrareds using carbon fibers. Daiugin is a surface radiant; it is capable of release a lot more far-infrared rays than any other type such as lamps, sticks, or heaters.

The 80% of the solar energy is infrared, and the 80% of it releases 10-20 micron waves. The element that benefits the survival of life form is the sunlight.. In the sunlight, there are visible rays, UV rays, and infrared rays (far-infrared). The UV has sterilizing effects and infrared rays are essential to human life. If energy is applied to the material molecules that construct the human body, it stimulated cellular breeding and mitosis, resulting hormone production and conditions for growth, which proves that it is essential to human life. The rays between 4 micron and 1000 micron are called far-infrared. There are UV rays, gamma rays, x- rays, infrared rays, and microwave rays in a light. UV rays, gamma rays, and x-rays waves are smaller than 0.4 microns, which is invisible to the human body. Infrared rays and microwave rays are bigger than 0.75 microns, which is too long to be seen by the human eye.
The infrared rays are classified into near infrared (0.75-1.5 micron), mid infrared (1.5-1.6 micron) and far infrared rays (5.6-1000 micron). Infrared rays is an energy wave not seen by the human eye, and is the longest form of light (mov-04.htm) and is capable of invading every kind of material or human body. A far infrared ray is capable of entering the human body up to 40mm depth, and stimulates cell division, resulting in rise of body heat. It can counteract against low temperature and is capable of heating an object directly; it is the necessary form of light to the human life.
