Far Infrared Rays
Far infrared rays (FIR) have the longest wavelength of any kind of infrared light, and thus are the only kind of infrared light that can deeply penetrate the human body.
When emitted by the sun or our Infinity Pro Power Bands, FIR penetrates through the skin to the subcutaneous tissues and is transformed from light energy into heat energy.
A FIR energy wave of similar length is emitted when natural stone - such as tourmaline or zeolite - is heated.
Some studies have shown that FIR energy emitted from stone can penetrate organic matter 80 times deeper than other heat waves.
