Better understand the jargon related to your Deep Heat Therapy mat!

There is a lot of science involved in the functionality and application of these mats. Here are definitions to some of the common mat-related terms:


Amethyst crystals have been known for centuries for their healing effects and calming properties, and they naturally emit negative ions. Amethyst crystals have an inherent wavelength that enhances cellular activity. The unique feature of Amethyst is that the Infrared Light produced or refracted by the amethyst crystals which generates the most bio-available and bio-compatible heat thus easily and deeply penetrating into the human body. When the amethyst mat is used at any temperature setting, even lower temperatures, the far infrared accelerates the negative ion production.


Indicating or involving life or living organisms.

EMF (Electromagnetic field)

An electromagnetic field is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. Positive ions can make us feel ill, and they can depress our nervous system. Our Deep Heat Therapy Mats are designed to be EMF free.

Far Infrared (FIR)

Part of the light spectrum from natural sunlight. A safe form of energy that heats objects by direct light conversion, producing radiant heat. As warm-blooded animals, we also emit far infrared heat, or radiant heat, which is a very beneficial and essential form of energy that can penetrate, refract, radiate and reflect.

Free Radicals

A type of unstable molecule that is made during normal cell metabolism (chemical changes that take place in a cell). Free radicals can build up in cells and cause damage to other molecules, such as DNA, lipids, and proteins.
Free radicals are oxygen-containing molecules with an uneven number of electrons. The uneven number allows them to easily react with other molecules. Free radicals can cause large chain chemical reactions in your body because they react so easily with other molecules. These reactions are called oxidation.

Negative ions

Oxygen atoms charged with an extra electron. Negative ions are created naturally by evaporating water, ocean surf, waterfalls and ionic minerals, such as amethyst and tourmaline.

In contrast, our homes and offices are full of harmful positive ions produced by air pollution and electromagnetic fields generated by cell phones, electronic wires and modern construction materials. Positive ions make us feel ill, and they can depress our nervous. They suppress the immune system and cause headaches, tiredness, anxiety, poor mental performance, sleep disturbances, eye problems and many real diseases.

The healing effects of negative ion therapy were discovered almost 100 years ago by Russian scientist, Tchijevsky, a biophysicist who founded “helio-biology” (the study of the sun’s effect on biology) and “aero-ionization” (the study of the effect of ionization of air on biological entities). Tchijevsky invented the first negative ions generator.

Negative ionization of the air now is mandatory in Russia and many European hospitals and workplaces.

The FIR Mat’s negative ions are delivered directly to the body by conduction through the skin, and they regulate the body’s pH while rapidly increasing cell function and the flow of oxygen. This differs greatly from the ambient air ions produced by popular negative ion generators used for air cleaning.

Radiant heat

The heat energy emitted from a warm element, such as a floor, wall, or FIR Mat, which warms people and other objects rather than directly heating the air in the room.
