What is red/near infrared light therapy?




Red/near-infrared (near IR) light therapy, commonly called LLLT (low level laser therapy) or photobiomodulation, is a type of therapy involving particular wavelengths of light, used to achieve either local or systemic health benefits.

Red and near IR light exert substantial local effects on tissues, the mechanisms by which this happens are not fully established, though multiple hypotheses have been put forth. In addition, they have been shown to have systemic benefit as well. While past research has focused more on the local effects, anecdotal evidence and some recent published research suggests the systemic effects are also very significant. The underlying mechanisms producing these effects may well be different than those underlying local effects. One of our hopes with providing high-powered lights is for people to be able to engage in high-dose therapy for systemic effects, as we ourselves have.
