What is far infrared energy?

The infrared segment of the electromagnetic spectrum is divided into 3 segments by wavelength, measured in microns, or micrometers (a micron = 1/1,000,000 of a meter) 0.076 ~ 1.5 microns - near or close infrared; 1.5 ~ 5.6 = middle or intermediate infrared and 5.6 ~ 1000 = far or long wave infrared.

When warmed by the sun, the earth radiates infrared rays in the 7 to 14 micron band (a frequency that measures energy which is released in different frequencies - similar in concept to radio stations that operate on different frequencies).  The most beneficial in human terms is considered to be around 10 microns.  The natural resonant frequency of the human body (i.e. the ability to absorb) ranges from approximately 8 to 15 microns.  The Far Infrared segment occurs just below red light (or "infra") as a low energy band and is not visible to human eyes but we can feel this type of light, which we perceive as heat. 

Biological research has shown that Far Infrared Rays are the most beneficial to the human body.  Far Infrared energy increases our body's molecular vibration (actually vibrates the cell structure to help break down the connections between deposits such as additional fats and toxins) generating heat which is absorbed through the skin.  Continuous vibration of the body's molecules increases dermis temperature, enlarges blood vessels, stimulates blood circulation and activates metabolism in tissues and cells providing therapeutic and tissue regenerative properties when humans absorb the energy.

The waveband, the distance the rays have to travel, the angle of the rays, whether the temperature is constant and the length of time an object is in contact with the rays, will all determine the efficacy of Far Infrared based products.
