The heating technology developed by Sunlighten is one of a kind. Each wavelength requires a different complex equation involving surface size, surface temperature and material. Sunlighten’s patented heaters allow for all three wavelengths (near, mid and far), plus red light, to be recreated in one place. The six pre-set programs direct the heaters to emit the optimal blend of infrared wavelengths – based on 56 data points from 37 studies of how infrared interacts with the body – to achieve the desired result.
