Laser is a non-thermal, non-pharmaceutical therapy known as photomodulation. Laser treatment causes biostimulatory effects by releasing light in the red to near infra-red range. These are long wavelengths, The longer the wave length, the deeper it penetrates. It causes the release of endogenous opioids i.e. endorphins for pain relief, improved circulation and oxygenation of the tissues, and increased ATP (adenosine triphosphate) which are the energy units that drive all chemical reactions in the body. Healing is 50% faster.
