Repeated Far Infrared (FIR) Thermal Therapy has been shown to significantly reduce body weight and body fat in obesity- (Exp Biol Med 2003). It provides one of the safest and most effective means of losing weight naturally.
As the body is warmed the body's natural thermostat is activated. As the body's temperature rises the sweating mechanism can be activated to help cool the body. As the body produces sweat, energy is used for this process which helps to increase the number of calories burned.
So more calories can be burned during the Far Infrared treatment - circulation may also be boosted which has a similar effect to exercise. (JAMA 1981)
An increase in circulation can help more oxygen and blood to reach fat stores which often have a poor blood supply. This improvement in blood flow may be one mechanism by which Far Infrared Thermal Therapy (FIR) helps to induce weight loss and fat reduction.
