What is full spectrum infrared energy?Updated a year ago

Full spectrum infrared energy is that part of the solar (sun) electromagnetic spectrum which living beings, although they cannot see it, feel as heat. Full-spectrum, infrared energy includes three frequencies near (NIR), mid (MIR), and far (FAR) frequencies. NASA scientists have determined their differing wavelengths and health science studies have determined what these different wavelengths do. Therasage devices are all full-spectrum because we have identified that each of these wavelengths are essential for natural healing in the body.
