FAR Infrared is completely safe and, as part of the electromagnetic spectrum, is the same wavelength that our bodies naturally absorb and emit.
Our Heated Anti-Fatigue Mats work by converting electricity into radiant heat, which is the most basic and natural form of heating known to humans (it’s the same type of comfort we feel from from an environment warmed by the sun).
It's also the wavelength most efficiently absorbed by our bodies and has a bigger impact on our comfort levels than moving hot or cold air (convection heat). Our skin naturally prompts us to avoid the suns hottest waves, Near (Shortwave) infrared and the waves we find most comfortable are those that are absorbed by our environment and radiated back – called Far and Medium (or Longwave and Middle) Infrared.
