Cold laser therapy is a method of speeding up the healing of nerves, muscles, tendons, ligaments, joints, bone, and skin. The laser works via a process in the body called photobiology, and is not the same as red light or light-based heat therapy.

When the cells in an area of the body are actively working to heal and repair, they need a great deal of energy. By stimulating the cells with specific light frequencies, the mitochondria (a cell’s energy factory) are sped up, producing more adenosine triphosphate (ATP). Having more energy available allows your natural healing process to act faster and more effectively. It is also possible to stimulate the function of immune cells in the case of having a cold or the flu.

It is most useful in improving the healing response to soft tissue or joint injuries, localized inflammation, or nerve irritation. It can also have a significant improvement in heal time when applied after surgery.
