Far infrared waves penetrate deep into our body for a deep heating action which allows for the body to activate the sweat glands. The sweat glands offer one of only a few mechanisms that the body has to eliminate toxins and since the skin is the largest organ in the human body it is apparently a very good means for elimination. The far infrared rays consist of similar wavelengths as that which is emitted naturally by the human body. This is one potential explanation of why many feel energetically rejuvenated and balanced from contact with far infrared waves. In Asia it is also believed that far infrared waves help improve blood circulation and recovery from fatigue.

Infrared Saunas use Far Infrared energy to penetrate the body's tissue. Tests have shown that the energy output is tuned so closely to the body's own radiant energy that our bodies absorb as much as 93% of the far infrared waves that reach our skin. By comparison, conventional saunas must rely only on indirect means of heat: first, on convection (air currents) and then, conduction (direct contact of hot air with the skin) to produce its heating effect. Some benefits of the far infrared sauna include; promotes natural healing of soft tissue injuries, accelerates healing in newer injuries, relieves muscle pain, eases joint pain and stiffness, provides relief in chronic cases, removes toxins, improves skin condition, improves circulation, burns calories and controls weight, improves the immune system and reduces stress and fatigue.
