Far Infrared Rays (FIR) have been called the “Light of Life”, because they comprise the particular portion of the entire energy spectrum that’s most responsible for sustaining life on Earth—photon energy. To understand this, let’s look at the full spectrum of energy emitted by the Sun:
By far, most of the Sun’s energy is in the infrared part of the spectrum. These rays are not seen as light (the visible part of the spectrum), but rather are felt as heat. Infrared rays are divided into three wavelength frequencies: near, middle and far. Far infrared waves are the longest of all infrared waves, measuring from 5.6 to 1,000 microns.
A narrow spectrum of far infrared waves in the 4 to 14 micron range is known to have particularly beneficial and healthful effects on the body. Why is this so? Consider that human beings send and receive FIR waves measuring in the 3 to 50 micron range, with the greatest output around 9 to 10 microns. When receiving FIR waves of similar length, such as those emitted by Tourmaline, by the warming that is produced by these waves can penetrate bodily tissues deeply and very uniformly.
This warming therapy of far infrared, and its other effects on the body are known to have many health benefits, including:
It should be noted that the above benefits experienced may vary from individual to individual.
