Photobiomodulation (PBM) is a non-invasive, drug-free therapy that uses specific wavelengths of near-infrared and red light to stimulate healing and optimization at the cellular level — essentially using light as a tool to improve how the brain and body function from the inside out. Vielight is one of the leading developers of PBM devices specifically designed for brain health, producing wearable devices that deliver near-infrared light transcranially — through the skull — as well as intranasally through the nasal cavity, which provides a direct pathway to the brain's blood supply and deeper structures.

The mechanism is remarkably straightforward at its core — near-infrared light penetrates tissue and is absorbed by mitochondria, the energy-producing powerhouses inside every cell. This stimulates the mitochondria to produce more cellular energy (ATP), reduces oxidative stress and neuroinflammation, improves cerebral blood flow, and activates a cascade of regenerative biological processes that support the health, repair, and optimal functioning of brain tissue. Think of it like recharging the brain's batteries and reducing the internal inflammation that slows everything down.

Photobiomodulation can benefit a wide range of conditions including cognitive decline and dementia, traumatic brain injury, depression, anxiety, PTSD, chronic fatigue, brain fog, insomnia, chronic pain, and general brain health optimization — making it one of the most versatile tools in non-invasive brain health care.
