FIR infrared ray energy is a part of the natural light spectrum of sunlight, minus the skin damaging UV, which is why NASA spacecraft have utilized this heat. In Asia and Europe it has already revolutionized health and beauty products.

Far Infrared ray is a form of light energy form the sun. It falls within the same family of Infrared Rays in the light spectrum, but due to its longer wavelengths human eyes, just like Ultraviolet Rays, cannot see FIR. The energy is ESSENTIAL & BENEFICIAL for all human beings.

FIR has the ability to penetrate, refract, radiate & reflect. The human body can absorb FIR because of its deep penetrating ability. When FIR penetrates through the skin to the subcutaneous tissues, it transforms from light energy into heat energy. The thermal effect within the deep layers of tissues cause blood vessels in capillaries to dilate, promoting better blood circulation, and the heat produced helps to get rid of body toxins and metabolic wastes through sweating.

Many people with chronic illnesses find the high temperatures inside a regular sauna or steam room intolerable. In these traditional systems, the inside of the body is heated completely from the surface of the skin. Even though you feel very hot in these units, the heating is quite shallow - only a few millimeters below the skin.

In the Aesta FIR Sauna Dome or the Aesta Mats, invisible light rays emanate from several Far-Infrared emitters. This Far-Infrared light penetrates deep into the fat and muscles of the body, creating a more powerful detoxifying influence upon the deeper tissues of the body. As well, since the air temperature remains much lower than in a traditional sauna, you feel more comfortable. Sweating often begins before you feel very hot at all and the sweating is more profuse than in a traditional sauna.
