The electromagnetic radiation of a wavelength that is longer than that of an observable light but shorter than that of radio waves is called an infrared (IR). This same radiation is what far infrared saunas use to heat the body instead of the air around the person.
Far infrared radiant (FIR) treatment is generally harmless. It is not an ultraviolet radiation. The radiant heat produced undergoes a process called conversion. During this stage, the heat warms the object or the body and does not elevate the surrounding air temperature exactly like the sun’s rays will warm your body.
Most infrared sauna rooms are made of wood with a number of infrared heaters. The space inside does not necessarily need to be enclosed. In humid environments, the sauna is left open but doing so does not affect the heating process since heaters do not depend on air.
The type of heaters used in infrared saunas is of special type. It produces waves that are responsible for heating the body. Its temperature is greatly cooler compared to traditional saunas. The heat inside ranges from 430C to 540C (1100F to 1300F).
