What is infrared heat?

infrared heat is a form of energy that heats objects directly through conversion without heating the air between. It is also called radiant heat, infrared energy, and IR.

The Sun produces most of its energy in the Infrared Spectrum of light. This band of light is not visible to the human eye. But we can feel this type of light as heat. Our atmosphere has a window that allows infrared rays in the 7 to 14 micron range to reach Earth's surface. The Sun is the principal source of infrared heat. Think about how warm you feel on a cold winter day while sitting in your car-your body is absorbing infrared heat from the sun.

Our bodies produce infrared energy to keep us warm and use it for tissue repair. FAR Infrared energy is radiated through the skin at 3 to 50 microns. The FAR Infrared waves between 7 to 14 microns have proven to have special regenerative effects on the body, with an optimum absorption at the 9.4 micron frequency. TheraSauna emits the greatest amount of Infrared in the 9.4 micron range. When any cell or tissue in the body is exposed to these levels of infrared heat, response mechanisms stimulate the healing process in the body.

Our tissues normally produce infrared energy and burn it as fuel to keep us warm and use it for tissue repair. Tissue production of infrared energy is associated with a variety of healing responses. Occasionally, the infrared energy in our tissues needs a boost to insure best possible healing for tissue repair. Dr. Tsu-Tsair Oliver Chi, when summing up how infrared devices are attuned to the human body, reported that body tissues that need an infrared boost selectively absorb rays. After boosting a tissue's infrared energy, the remaining rays pass onward harmlessly. This phenomenon is called "resonant absorption."
