I am not a teacher or a scientist however I have done my research. In this article I will go over a brief overview of Far infrared technology in LAYMANs terms that anyone can understand.

Our sun accounts for 99.8% of the energy mass in our solar system. The sun's rays provide the earth and its inhabitants with our primary source of energy, without which life would not survive.

Sir William Herscel discovered the Far infrared rays(FIR) wavelength in the 1800's. FIR rays are produced by the sun's continual elemental chain reactions. Known as the 'Light of Life', infrared radiation is actually part of the sun's invisible spectrum. We can, however, feel the rays as heat.

Our sun produces most of its energy output in the infrared segment of the spectrum. An interesting characteristic of FIR rays is how easily this energy can penetrate human tissue. In the same way Far infrared rays stimulate photosynthesis in plants, our metabolism is stimulated by the FIR rays as we absorb it through the skin and eyes.

Far-infrared rays in the wavelength 4-14 micron are the safest and most beneficial. The maximum output, which is similar to the resonant frequency of a H2O or Water molecule, is around 9 microns. The human body is 70% water and Far infrared causes the body's water molecules to resonate. This dilates the capillaries and increases the pH within the body by reducing acidity, which then facilitates the removal of toxins from the body.

Lifestyle and environment play a factor in the amount of Far Infrared rays we recieve. The human body needs continuous replenishment from a wide variety of ions, rays and other energy sources to top up the depleting elements we lose everyday.

Far infrared ceramic inserts were made commercially possible in Japan by utilizing NASA's innovative development of bio-ceramics. Far infrared therapy is now extensively used in Japan, Korea and China.

Far infrared white ceramic inserts emit Far infrared in the specific wavelength of 4 - 14 micron. This wavelength is identical to the Far infrared wavelength emitted by the sun and is the best for wellness and the safest to humans.

FIR technology falls into the wellness category and as most people who sell it will tell you it is not a medical device. The only thing I can recommend is listening to the people that have used Far infrared products and hear what they say.
