Studies show that low-level lasers can help regenerate cells, decrease pain, reduce inflammation, improve circulation, and stimulate hair growth, to name a few examples.

In 1991, a study was done in Novosibirsk, Russia that applied directly to the study of acupuncture. Researchers shined light on various parts of the body and found that light travelled under the skin to other acupuncture points, but it didn't travel to places that were not on acupuncture meridians. It appears that the body contains a sort of fibre optic network—where light enters an acupuncture point, travels through the meridian and can be detected at other places along the meridian with a sensitive photon detector. This is a fascinating study showing how light is actually received, used and transmitted throughout the body.
