ed light therapy is also called low-level laser therapy (LLLT), low-power laser therapy (LPLT), and photobiomodulation (PBM)
Red light therapy also referred to as low-level laser therapy (LLLT) or photobiomodulation—is the act of using red light (or near-infrared light) for beneficial properties on the body.
These beneficial properties are outlined in detail below, but red light (in the proper intensity and dose) has a therapeutic or healing effect on the tissue and body.
Red light therapy may involve using a laser that emits light in the red light spectrum onto an injured body part or using a red light LED shone on the body, as practical examples.
Research has shown that light in the red and near-infrared spectrum has a lot of benefits on the body. This light typically ranges from 620 nanometers (nm) in length to around 1000nm in length.
These specific wavelengths penetrate very deep into the bodily tissues and are also absorbed very well by the body.
