FIR ray is part of the infrared ray and is a kind of electromagnetic wave that is invisible to human eyes. It’s wave length is between 3μm to 1000 μm. It can release astro energy. It’s energy can penetrate 3-4 cm deep under skin  and cause the resonance of body cells to produce heating effects.

The cells of all the life-forms on earth will naturally activate and flourish when radiated by FIR.  FIR owns the features of radiation and penetration. It can penetrate organizations deep under skin (3-5 cm), muscle, bone and entrails resulting in calefaction and heat moxibustion.

FIR acted on human body with three features: one is radiation, one is strong penetration and the other is absorbing, vibration and resonance. FIR ray energy can penetrate deep into human body and then turn into heating effect. This will cause the vibration and resonance of the body cells and therefore promote the vigor of the cells. The heating effect will expand the tiny blood vessel, strengthen it’s self-discipline and accelerate blood circulation. Due to the vibration and resonance effect, the water molecule inside the cells will be energized and the combination force will be strengthened. Therefore, the big molecules of protein will be energized. By speeding up blood circulation, the supply of nutrient and ferment is accelerated, metabolism is activated, immune force is strengthened. It also has the effect of deodorize, dryness, dehumidify and antibacterial.

The average temperature of human body is 36.5℃ that equals to the wave length of 9.4μm. Radiated by FIR ray, the molecule movements of human body will be activated since the two wave length will overlap with each other and therefore be strengthened. Resonance is applied widely to fields such as warm-keeping, dryness, antibacterial, health care, beauty and slimming etc.

HJ-626 FIR heat jacket is a new product developed based on the expertise we accumulated for many years in this field. It can release FIR ray with a wave length of 9.38μm. This wave will resonance with human body. The water molecule in the cells will vibrate to produce heat and cause the rise of temperature in the body. The expand and contract of cells will cause the expand of tiny blood vessels and promote the blood circulation to reach the effect of warm-keeping and health care.
