Red light therapy is a treatment that stimulates natural cellular processes. Similar to how specific wavelengths (at the opposite end of the light spectrum) can be used to treat chronic conditions. Red light therapy (also known as photobiomodulation) uses a combination of red and near-infrared light to activate a number of biological processes.

Photobiomodulation (PBM) employs red or near-infrared (NIR) light to stimulate healing, protect tissue from dying, increase mitochondrial function, improve blood flow and tissue oxygenation. PBM can also act to reduce swelling, increase antioxidants, decrease inflammation, protect against the death of cells which occurs as a normal and controlled part growth and development.

PBM has been shown to increase regional cerebral blood flow, tissue oxygenation and improve memory, mood and cognitive function. Clinical studies have been conducted in patients suffering from the chronic effects of TBI. There have been reports of improvements in executive function, working memory, and improved sleep. Functional magnetic resonance imaging has shown modulation of activation in intrinsic brain networks likely to be damaged in TBI (default mode network and salience network).

Traumatic brain injury (TBI) is caused by some type of trauma to the head, often resulting from road traffic accidents, assaults, falls, sports injuries, or blast injuries suffered in military conflict.
A number of articles have shown how transcranial PBM is effective at increasing memory, learning, and the overall neurological performance
