- The typical infrared sauna sold in the U.S. is far-infrared. These low-energy wavelengths provide virtually no photobiomodulation health benefits; they only heat your body superficially
- The near-infrared wavelengths can penetrate up to 4 inches into your body’s tissues. The incandescent light bulb is the most efficient way to heat tissue because it is mostly near-infrared
- Only a few percent of solar radiation are far-infrared. About 40 percent of the sunlight spectrum is near-infrared
- Sunlight and incandescent light interacts with light receptor proteins called chromophores in your body. When light hits the chromophores, they activate a variety of biological processes. Near-infrared also activates the mitochondrial chelating systems in the cells
- Near-infrared light therapy stimulates your mitochondria to release nitric oxide and boost ATP production which, together, promote healing effects such as DNA repair and cellular regeneration.
