Far Infrared Radiation (FIR) is a form of light energy from the sun. It falls within the same family as Infrared Rays in the light spectrum, but due to its longer wavelengths, Far Infrared(FIR) cannot be seen by human eyes, just like ultraviolet rays and X-rays. This energy is absolutely essential for all living things, including human beings.
Far Infrared(FIR), by it physical properties, has a deep penetrating power. It can penetrate through the skin into the subcutaneous tissues to improve blood circulation promoting overall metabolism. FIR can get rid of bodily toxins and metabolic by-products and improve cellular vitality. Upon penetrating the skin, Far Infrared(FIR) transforms from light energy into heat energy. The thermal effect within the deep layers of the tissues causes blood vessels and capillaries to dilate, promoting better blood circulation.
Global pollution diminishes the opportunities for human bodies to absorb Far Infrared(FIR) from the sun, as our ancestors did. It is because the FIR from the sun are blocked by fog, smog, polluted air, highrise buildings,and electronic pollution such as EMF (Electro Magnetic Frequency), emitted by hi-tech products such as microwave ovens, cellular phones, computers, fax machines and other electrical appliances etc. The inadequacy of Far Infrared(FIR) absorption causes many diseases including but not limited to; headaches, migraines, contusions, muscular pain, nervousness, depression, fatique, stomach ulcers, gastric troubles, constipation, high and low blood pressure, poor circulation, chronic bronchitis, asthma, insomnia, etc...
Advantage of a Far Infrared Sauna(FIR Sauna) over a conventional sauna; A conventional sauna heats the air in the chamber to a very high temperature, which in turn heats our body. A Far Infrared Sauna(FIR Sauna) works differently. Neither oxygen molecules nor nitrogen molecules in the air can block the Far Infrared(FIR) wave; therefore, the Far Infrared(FIR) unique wave length penetrates directly onto our body a couple of inches. It makes us feel quite warm and we perspire profusely, but our skin is not hurt by the hot air. Some heavy metals accumulate under our skin and the Far Infrared Sauna(FIR Sauna) is very good for sweating out heavy metal deposits under our skin.
The infrared radiant sauna has been greatly used in treating people who suffer from toxin load. These patients are very high in toxic loads, and the detoxification pathways in their bodies suffer. When one is able to reduce the toxins and heavy metals, their symptoms most often greatly improve. Many people unknowingly suffer from mercury poisoning, and other heavy metal such as lead and aluminum. The infrared sauna raises the core temperature which accelerates the removal of these toxins and also improves a number of areas in the immune system. Infrared helps purify our cells, especially the cells in our fat where our bodies store waste and harmful toxins, such as cholesterol and heavy metals..
Humans, at normal body temperature, radiate most strongly in the infrared at a wavelength of about 10microns (micron is the term commonly used in astronomy for a micrometer or one millionth of a meter). The long wave infrared occurs just below "infra"to red light as the next lowest energy band. This level of light is not visible to the human eye, but we can feel this type of light as heat. The earth radiates rays in the 7 to 14 micron range with its peak output at 10 microns. The infra-core sauna heating ceramic emitters, which are 96% radiant efficient, have a majority of output from 5.6 to 25microns. This output is evenly spread around the 9.3 micron pivot point of maximum human output. The energy output from the infrared sauna matches so closely to the human body's radiant energy, that our bodies take in close to 93% of the infrared waves that reach our skin.
