7.98 microns. [7.98 microns = 5268 / (200F + 460) ]
At an average of 7.98 microns you are getting the majority of the wavelength at around 8 microns. But because it is an average, you are getting some waves at 6 microns and some waves at 10 microns. At 6 microns water molecules begin to vibrate. When water molecules vibrate, toxins are shaken off of the cell (cells are made of water and are released into the body’s interstitial fluid where it can be excreted through the skin and other waste duct’s). The body releases these toxins and heavy metals through the lymphatic system, the liver, the skin, and removed through the small intestine and out of the body. It is true that your body does absorb far infrared at its highest amount at 9.4 microns because that is our skin’s surface temperature.
