FIR is an abreviation which stands for Far-infrared radiant.

FIR heat is a completely safe form of naturally occurring energy that heats objects by a process called direct light conversion. Radiant heat is also called infrared heat or infrared energy. Direct light conversion warms only the object and does not raise the temperature of the surrounding free air. This type of energy travels 2-3" deep into the body and is thought by many to increase circulation and nourish damaged tissue.

Infrared (IR) radiation is electromagnetic radiation of a wavelength longer than that of visible light, but shorter than that of radio waves. The radiation penetrates the body and heats through a process called conversion, instead of heating the air around you.

Sadly the insurance companies in the USA do not. In Europe some insurance companies recognize the health benefits to the people and do cover the expense.

Infrared light has no ultra-violet rays like the sun does, which causes damage to your body. It is in reality safer than natural sunlight. Infrared light is absorbed in the body quickly and safely.

Just about all life requires some FIR heat from the sun. Remember that FIR is not ulraviolet radiation. This narrow band of FIR energy is within the spectrum of 5.6 to 15 micron levels. This energy travels only 2 to 3 inches into your body causing the circulation to increase and damaged tissue to be refurbished.

Most people do lose some weight. Sitting in the FIR sauna causes your metabolism to speed up causing up to 600 calaries to be burned for every 30 minutes your in there.

Using the IFR Sauna once per day is acceptable. Some articles say twice a day is acceptable. The main point to watch out for is that you must keep yourself hydrated.
