Far-infrared radiant (FIR) heat is a naturally occurring energy that heats objects by direct light conversion. Direct light conversion warms only the object and does not raise the temperature of the surrounding free air. FIR heat is not ultraviolet radiation but a narrow band of energy within the 5 to 15 micron level. This type of energy travels deep into the body to increase circulation and nourish damaged tissue.
The sun is the primary source of radiant energy, but not all of this energy is beneficial. Although life needs energy from the sun, too much sunlight damages the skin. FIR heat provides many of the health benefits of natural sunlight without any of the dangerous effects of solar radiation.
Is infrared heat better than traditional steam heat?
Infrared heat has some advantages over traditional steam heat saunas, however many steam sauna advocates feel that an infrared sauna does not provide the same relaxing and invigorating experience as a steam sauna. This can be an issue of personal preference.
Infrared heaters warm the body in the same manner as natural sunlight. FIR heat therapy uses the wavelength of the visible and non-visible light spectrum of sunlight that heats the body normally.
Traditional steam saunas raise the temperature of the air to a very high level within the chamber to warm the body. Some people have difficulty breathing in this extremely warm air. FIR saunas work differently: instead of heating the air within the enclosure, FIR saunas heat the body directly. In the FIR sauna, the body perspires but avoids the hot air of a traditional steam sauna.
Why Is FIR important to the human body?
FIR has the ability to penetrate, refract, radiate and reflect. The human body can absorb FIR because of its deep penetrating ability. When FIR penetrates through skin to the subcutaneous tissues, it transforms from light energy into heat energy. The thermal effect within the deep layers of the tissues causes blood vessels and capillaries to dilate, promoting better blood circulation, and the heat produced helps to get rid of body toxins and metabolic waste through sweating.
