Photo-therapy, or to give it the correct name; ‘photo-biomodulation’ is the application of therapeutic light, with the aim to stimulate or inhibit.
Red light and infra-red have been studied in detail for use in therapeutic healing tools. It has been established that specific wavelengths are effective at stimulating the healing process, if used in the correct dose. This stimulation takes place at the cellular level, and sites can be targeted directly or indirectly with light devices.
Much of the study, until recently, has been done on laser devices, but now LED units are coming to the fore, and demonstrating pretty much identical results.
Altering the dose, or the application of the light can produce a desired outcome for the presenting issue, whether it be to stimulate healing at the site of an injury, or ease pain.
