What is infrared?

Infrared light is a particular bandwidth/ frequency of sunlight.  This infrared light energy is divided into three spectrums: Near, Medium and Far infrared, which are defined by frequency ranges measured in small wavelengths called microns.  The far infrared light spectrum measures from 4 microns to 1000 microns. Far Infrared Sauna heater panels are designed to reproduce a specific bandwidth of light energy that perfectly matches the exact frequency at which the human body emits and absorbs the maximum amount of light energy. (7-14 microns) .. much like your TV being tuned to a certain channel. This channel of far infrared light is able to safely heat the human body directly without creating high air temperatures in the sauna cabin.  The 7-14 micron bandwidth of Far Infrared Radiant (FIR) energy achieves the maximum penetration into body tissues and produces a unique vibration at the cellular level called Resonant Absorption. The process of Resonant Absorption helps to create physical and chemical changes within the human body that have proven to be most beneficial for numerous health problems. Sauna FAQ Home
