How It Works

Blood is the conduit for the transport of oxygen and nutrients to the cell and waste products, like lactic acid and carbon dioxide, away.

Generating local circulation is one of the primary mechanisms of laser therapy. In the capillaries, bloodflow is regulated through microscopic pressure and thermal gradients. Targeting water with radiation, most efficiently at 970 nanometres, is the best way to produce the temperature gradients that will increase localized bloodflow.

Once more blood reaches the cells, the hemoglobin that carry the oxygen have to reduce or drop off their oxygen supply. They do so sporadically at their normal pace. At the same time, these blood cells carry the waste products away from the cells.

Laser therapy can speed up this process, because when hemoglobin absorbs light, most efficiently at 905 nanometers, this reduction process increases, and the blood dumps more of its oxygen to the cell to be processed into cellular energy.

Once out of the blood, oxygen passes through the membrane and into the mitochondria where it is processed by chain of respiratory enzymes whose end product is ATP. Here, oxygen is processed by the last of the respiratory chain of enzymes.

Cytochrome oxidase is the transport enzyme between the end of the respiratory chain and ATP Synthase, the enzyme that produces ATP. Each back-and-forth cycle produces a molecule of ATP, and without laser, this process happens at its normal pace. But in either state of this enzyme, whether reduced or oxidized, if it absorbs laser light, most officially 800 nanometers, it will flip. More laser means more energy to the cell and quicker healing by the body.
