Summarizing the Role of FIR in the Human Body

First:

FIR penetrates four or five centimeters into the dermis -- from muscles into blood vessels, lymphatic glands and nerves. It effects every living cell and produces warmth. In other words, through cell tissue "micro friction" and the vibration of molecular resonance, chemicals within cells are activated.

Second:

The human body is warmed internally through molecular resonance. Capillaries expand activating blood circulation throughout the whole body to enhance metabolism. As a result, metabolic disturbances are ameliroated, tissue regeneration is promoted, and there is markedly enhanced growth potential.

Third:

It plays a comprehensive and compensating role in living things. That is why it can be designated as a heat-type physical therapy apparatus. The warming effect can be very helpful in elimination of such things as the waste products generated by aging, heavy-metals, toxic substances secreted by the sweat and dermis-layer fat glands.
