The InfraBeds amethyst quartz grade A crystals when heated create this far-infrared emission profile.
Infra-red means “below-red” just like ultraviolet (UV) means “above-violet.” These two parts of the spectrum, though they are both invisible, have very different effects on the body. Ultraviolet (UV) light has been associated with many health risks whether it is from laying out in the sun too much or from tanning salons. Infrared light is the exact opposite end of the light spectrum and is associated with many positive and healthful effects. (See Infrared safety and benefits Vimeo.)
Far-infra-red-energy InfraBed amethyst quartz generated infrared uses the far part of the infrared spectrum, and emits waves of 2-22 microns. The human body best absorbs infrared between 3 and 15 microns, reportedly with the very best ‘sweet spot’ at approx 9.4 microns.
