Sun is the most natural source of heat. More than half of the solar radiation energy reaches Earth in the form of InfraRed Light which extends from the nominal red edge of the visible spectrum as frequencies decline from 430 THz to 300 GHz. At the same time, the wavelengths go up from 0,75 to 1000 microns.
IR light is a low-temperature source of radiant heat with a lower frequency and longer wavelengths than visible light and higher frequency and shorter wavelengths than microwaves.
Industrial standards usually define Infrared rays as FIR, NIR, and MIR:
- Far Infrared Rays (FIR) with frequencies from 300GHz to 37 THz and wavelengths from 8 to 1000microns.
- Mid InfraRed Rays (MIR) with frequencies from 37 to 214 THz and wavelengths from 1,4 to 8microns.
- Near InfraRed Rays (NIR) with frequencies from 214 to 430 THz and wavelengths from 0,75 to 1,4microns.
- Near InfraRed rays are called so because they are the nearest to visible light in the spectrum.
Far InfraRed rays are the most distant from the visible light, but they are the nearest to the microwave rays famous for the deepest heat transferring.
Though the Near Infra-Red Rays are the most powerful and the human body normally radiates at medium MIR wavelengths in the range between 2 and 10 microns, the Far Infra-Red rays with longer waves are absorbed by the tissues more efficiently.
FIR heat is also better detected and felt than NIR, so the risk of overhead is much lower.
Far InfraRed is nature’s most efficient heat. This type of heat is based on the usage of InfraRed (IR) Light, the healthiest part of invisible sunlight that transfers only the heat without any harmful radiation or ultraviolet rays.
The impact rays gently envelop the body in a relaxing environment.
"FIR rays for health" is a safe, well-known, time-tested technology invented in Japan more than 50 years ago.
It is mostly known for FIR Saunas, which have been used to invoke wondrous benefits for many years worldwide.
The FIR rays in Ereada® mats are refracted and magnified by the special layers with Bamboo carbon, Charcoal, Yellow Clay (Ochre), and especially by the thick layer of small natural Amethyst and/or Tourmaline tumbled crystals or by the disk-shaped whole Amethyst, Agate, Tourmaline and Jade stones to penetrate with the better efficiency than the carbon InfraRed Sauna heat.
Why is Amethyst called the “superconductor” of InfraRed rays?
Of course, not in the “physics" meaning of this term. This term here outlines the ability of the crystal to absorb heat energy in the wide wavelength range and then isolate, amplify and emit InfraRed rays in the narrow FIR and MIR range really valuable for mat technology. Amethyst delivers the steadiest, most compatible, and absorbable rays. It also helps to produce the healthiest Negative Ions synergistic to InfraRed heat applications.
Ereada® Amethyst Mat emits both FIR and MIR heat with 93% efficiency in the best-utilized wave range of 4-16 microns, which is also called a “life” or “bio-resonance” range.
Green Jade is the second FIR emission gem, also showing potent properties. Far InfraRed Emission Power of the mats reaches 3.66x102W/m2 by Korea Conformity Laboratories tests.
