Far Infrared rays are an integral part of the sun’s spectrum, and though invisible it has been known for many years as the ‘Light of Life? in Korea, Japan and China, where the advantages of the FIR rays in therapeutic use first became common.
Since then Thermal Infrared heating has been used extensively in Europe and USA and the health benefits assessed and reported on. You may at times have used an infrared lamp as an aid to recovery from back pain or sprains and muscle lesions.
The sun emits FIR energy that is absorbed by human cells, causing a physical phenomenon called resonance. FIR rays vibrating at a frequency to that of the human body are thus able to activate cells, and reactivate as well as strengthen resulting in a better blood circulation and an overall improved micro blood circulatory systems.
Japan FIR heaters were used by the medical practitioners exclusively until 1979 when they were released for public use. The energy radiated by infrared [IR] rays heats objects directly, i.e. the intervening air is not heated, a process known as conversion.
The IR segment of the Sun’s electromagnetic spectrum is divided into 3 parts: the near infrared wavelength: 0.076 to 1.5 microns, medium infrared wavelength: 1.5 to 5.6 microns, and the FAR Infrared wavelength: 5.6 to 1000 microns.
Our sun’s energy output comes mostly from the IR segment of the spectrum, but it is the wavelength of between 6 and 14 microns that is most beneficial to humans and indeed to all living things on this earth.
What are the benefits?
FIR sauna therapy speeds up the metabolic process of vital organs and endocrine glands resulting in substantial caloric loss, i.e. weight loss, during a sauna session.
The increased blood flow speeds healing of sprains and strains and relieves pain. It also helps aching muscles to recover faster because the metabolic and toxic waste products are purged faster from your system and through the skin when perspiring. In fact, the skin is often referred to as the 3rd kidney because it is believed responsible for eliminating up to 30% of the body waste. With the extra nutrient reaching the skin the sought-after ‘glow’ is obtained whilst promoting healthy tone and texture, helping the body to ward off invading organisms.
