The natural resonant frequencies of water and organic substances are within the FIR frequencies. Therefore water and organic substances absorb energy easily from the radiated FIR wave. The normal absorption of resonant frequency for human body is 8 to 15 micron. However, the range of absorbable band of all organic matter on our planet is approximately 6 to 15 micron.

When an electronic wave of many different wave length is radiated on a substance, some waves are reflected away and some waves just pass through the substance. For instance, the visible light spectrum with very short wave length is reflected away; while a radio frequency with long wave length just passes through our body. However, some frequency wave bands are absorbed by the substance and the temperature of the substance arises.

The rule that living things exist wherever there is oxygen and water not always hold. Only few creatures can survive under the extreme conditions of the north and south poles due to the lack of infrared rays from the sunlight. This clearly indicates that the warmth generated by the infrared rays is sufficient to promote metabolism and subsequently support lives.

Invisible Ray of Near Infrared Ray can not be absorbed into the living body but reflected. However, FIR can be absorbed into the living body through penetration capability and provide heating effect. Based on these effects, FIR will be able to dilate capillary vessels, and ultimately increase blood circulation and active metabolism in tissues and cells. It also promote elimination of waste matters and harmful heavy metals out of human body.

• FIR activates water  molecules in the body

• These active molecules increase blood circulation

• Increase metabolism  efficiency

• Get rid of waste products  more quickly and   efficiently

• Decrease acidity in the blood 

• Increase the blood's Oxygen contents.
