Photobiomodulation (PBM) describes the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying.
When PBM is introduced into the blood circulatory system it can improve the overall functioning of the body.
This can be achieved by injecting red light into the vein or non-invasively, through the nasal vasculature. Evidence shows that the intranasal method improves biomarkers related to blood viscosity, blood lipids, red blood cell aggregation and oxygenation.
When PBM can be directed to the brain, various studies have shown improvements to a wide array of brain insults including:
- traumatic events: stroke, traumatic brain injury, and global ischemia
- degenerative diseases: dementia, Alzheimer’s and Parkinson’s
- and psychiatric disorders: depression, anxiety, post-traumatic stress disorder
