Blue light is a shorter wavelength and higher energy light. Blue light can kill some types of bacteria on the surface of the skin.

Red light, with its longer and less intense wavelength, can be absorbed by skin cells on the surface. This absorption of energy can speed up cellular processes such as ATP production and protein synthesis.

Near-infrared light (NIR) is a an even longer and weaker wavelength than that of red light. It can penetrate deep into human tissue, muscle, and bone and accelerate cellular processes such as production of ATP and creation of proteins

Far-infrared light has extra long wavelengths that are similar to microwaves. Far-infrared light is absorbed by water molecules in the body, raising internal core body temperature faster than outer ambient temperature.

Light behaves both as a wave and a particle. As a particle, each small unit or packet of light is called a photon. Each photon carries energy. This energy can be transfered and absorbed by human cells to promote healthy cellular function.

Red or infrared light photons penetrate the cell and are absorbed by the mitochondria. Inside the mitochondria resides the Electron Transport Chain, a small energy factory that produces energy necessary for healthy human cellular function.

The Electron Transport Chain houses free electrons, which can become charged or intensely energized. Upon absorbing a photon’s energy, these free electrons become highly energized and prepared to transfer this energy as needed by the cell.

Complex proteins like ATP, collagen, enzymes, antibodies, and hormones are all synthesized by bonding atoms together into molecules. This process demands energy, which is supplied by the highly energized electrons within the Electron-Transport Chain.
