La science a découvert depuis longtemps que les cellules humaines, sont sensibles à la lumière du soleil :
- Thnaks to UV from the sun our cells produce vitamin D.
- The white light stimulate the phtosensitivity of the skin and helps to have a better circadian rythm as well as a better sleep.
- The near infrared light (From 0,75 to1,5 microns) which is heating, stimulate mitochondria that produce more energy (AdEnosine triphosphate or ATP). Infrared lamps are used in sports notably for recovery and to help the muscle to relax.
The last researches on the light brought the scientists to specifically focus on the far-infrared light. They discovered that this light doesn’t heat and was favorable to the ddevlopment of all the living beings. Each organism emits its own far-infrared radiation (FIR) in wavelength included between 4 et 14 microns.
