Far Infrared Heat
Ereada® Mat brings the life-giving power of sun into your bed
The sun is the most natural source of heat.
More than half of the sun's radiation energy reaches Earth through infrared light, extending from the visible spectrum's nominal red edge. Frequencies decline from 430 THz to 300 GHz, while wavelengths increase from 0.75 to 1000 microns.
Of course, in summer, you may sunbathe to heat your body, but in addition to FIR (Infrared) light, you will also receive a large portion of the ultraviolet (UV) light part of the sun spectrum.
UV light is beneficial in small doses and is associated with vitamin D production. However, if overexposure occurs, UV light can cause burns and, in the long term, serious skin problems.
Radiant heating with stones and crystals is based on Infrared (IR) Light, the healthiest part of invisible sunlight that transfers only the heat without harmful radiation or ultraviolet (UV) rays.
FIR saunas and hot stone mats are widely spread and commonly used worldwide.
Hot stones naturally release FIR rays without the use of any infrared lamps. Amethyst and other gemstones emit FIR even if you lie on the unpowered mat and warm it up with the heat of your own body.
Electrical heating of the gemstones in your mat also generates FIR light. Natural Amethyst crystals convert heat energy into penetrating far-infrared rays.
Higher temperature settings provide more far infrared ray emission by the gemstones. But even at low and medium levels (2-5) with warm temperatures such as 98°F-133°F or 37°C-56°C, you will still get the benefits of far infrared.
Infrared light is a low-temperature and emission-free source of deep-impact heat with lower frequency and longer wavelengths than visible light and higher frequency and shorter wavelengths than microwaves.
Industrial standards define FIR, MIR, and NIR types of infrared light:
Far-infrared rays (FIR) have frequencies from 300 GHz to 37 THz and wavelengths from 8 to 1000 microns. They are the most distant from visible light but the nearest to microwave rays, famous for the most profound heat transfer.
Mid-infrared rays (MIR) have frequencies between 37 and 214 THz and wavelengths between 1.4 and 8 microns.
Near-infrared rays (NIR) have frequencies from 214 to 430 THz and wavelengths from 0,75 to 1,4 microns. Near-infrared rays are so-called because they are the nearest to visible light in the spectrum.
Though the Near-Infrared Rays are the most powerful, and the human body radiates typically at medium MIR wavelengths between 2 and 10 microns, the Far-Infrared rays with longer waves are absorbed more efficiently by inducing changes in the molecular vibrational state.
FIR heat is also better detected and felt by our body than NIR, so the risk of overheating is much lower.
Infrared Heat Emission by Ereada Mats
Ereada® Amethyst Mat naturally releases heat without infrared lamps, but using the warmed gemstones, both FIR and MIR heat in the so-called "bio-resonance" best-utilized wave range of 4-16 microns, with a 2-3 times deeper impact than traditional infrared saunas with carbon heating panels.
This effect is achieved by conducting, refracting, and restructuring infrared light through several layers: Charcoal, Carbon, Yellow Clay, and especially the thick purple Amethyst crystal layer.
The Amethyst Mat does not heat itself but radiates the most heat, so it feels warm, not hot to the touch, unless you turn the controller to the highest heat modes, cover the mat with a thick blanket, or lie on it. This allows the mat to deliver intense heat 6-8 inches deep.
The test results showed almost 93% Far-infrared Emissivity, with an Emission Power of around 3.71 x 10² W/m² concentrated in two peaks characteristic of Amethyst Crystals, around 5 and 12 microns.
Ereada® Gemstone mats naturally emit FIR and MIR heat in the wider wave range between 3 and 20 microns. Due to the different types of gems used, they are 90% efficient and have a more complex power distribution between different wavelengths.
Infrared Heat Emission by non-powered mats and pillows
Amethyst mats and Pillows do not work like conventional FIR heating pads in non-powered mode.
The human body's natural heat activates the deep FIR emission from the non-powered mats and pillows.
It is much less intensive, more delicate, and natural than electric-powered mats. By placing the Amethyst Mat or Ereada® Pillow against your body, you are allowing the Far-Infrared rays to reach the optimal temperature absorbed by your body.
However, if necessary, as in ancient times, you can achieve a higher intensity of infrared emission by preheating the Amethyst mats or pillows with sunbeams.
The tests showed 90,7% Far-infrared Emissivity with Emission Power as 3.66 x 10² W/m².
