Far Infrared Crystal Rays

What is Infrared LIGHT?

Sun is the most natural source of heat. More then half of the sun 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 while the wavelengths go up from 0,75 to 1000 microns.

IR light is a low temperature source of radiant heat with lower frequency and longer wavelengths than those of visible light and higher frequency and shorter wavelengths then those of microwaves.

Far-, Mid-, Near- InfraRed Light

Industrial standards usually define Infared rays as FIR, NIR and MIR:

  1. Far-InfraRed Rays (FIR) with frequencies from 300 GHz to 37 THz and wavelengths from 8 to 1000 microns.
  2. Mid-InfraRed Rays (MIR) with frequencies from 37 to 214 THz and wavelengths from 1,4 to 8 microns.
  3. Near -InfraRed Rays (NIR) with frequencies from 214 to 430 THz and wavelengths from 0,75 to 1,4 microns.
  4. 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-InfraRed 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-InfraRed rays with longer waves are absorbed more efficiently through inducing the changes in the molecular vibrational state.

FIR heat is also better detected and felt by our body than NIR so the risk of overheat is much lower.

Far InfraRed Heat

Far Infrared is nature’s most vital heat. It is based on the ability of hot objects (and Sun is the hottest of all) to transfer only the heat without any harmful radiation or ultraviolet rays. InfraRed (IR) Light is the healthiest part of invisible sun light that gives power to everything alive on the Earth.

The deep impact rays gently penetrate tissues.

"FIR rays for health" is a safe, well-known, time tested technology invented in Japan more then 50 years ago.

It is mostly known for FIR Saunas which have been used to invoke health benefits for many years all over the world.


The FIR rays of MediCrystal® Mats are not generate by special infrared lamps but are naturally released by warm stones and magnified by the special layers with Bamboo carbon, Charcoal, Yellow Clay (Ochre) and especially by the thick layer of small Amethyst tumbled and polished crystals or by the disk shaped whole Amethyst, Tourmaline and Jade stones to penetrate several inches deep with better efficiency then that of carbon InfraRed Sauna heat.

Why Amethyst is called “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 wave length range and then isolate, amplify and emit InfraRed rays in the narrow FIR and MIR range which may be really valuable for heating. Amethyst delivers the steadiest, most biocompatible and absorbable rays. It also helps to produce the healthiest Negative Ions synergistic to InfraRed heat.

The MediCrystal® Amethyst Mat emits both FIR and MIR heat with 93% efficiency in the best utilized by the human body wave range 4-16 microns, which is also called a “life” or “bioresonance” range. Green Jade is the second FIR emission gem also showing very powerful properties. Far-InfraRed Emission Power of the mats reaches: 366 W/m2, by Korea Conformity Laboratories tests.
