An insightful paper from Harvard

This excellent paper from Mike Hamblin’s team at Harvard Medical School reviews the LLLT mechanisms and the biphasic dose response. This paper neatly summarises the molecular and cellular mechanisms of LLLT, it gives a scientific explanation for the biphasic dose response, why a low dose has a stimulatory effect and why a high dose inhibits. Low power densities tend to get better healing and anti-inflammatory effects where higher power densities are more likely to inhibit (which may be useful if you just want an analgesic effect). I have to disclose an interest in this paper because I am a co-author.

Biphasic Dose Response in Low Level Light Therapy

Ying-Ying Huang, Aaron C.-H. Chen, James D. Carroll, Michael R. Hamblin

The use of low levels of visible or near infrared light for reducing pain, inflammation and edema, promoting healing of wounds, deeper tissues and nerves, and preventing cell death and tissue damage has been known for over forty years since the invention of lasers. Despite many reports of positive findings from experiments conducted in vitro, in … Continue reading
