Near-Infrared Light Therapy: A Promising New Approach in Brain Protection Research

Recent scientific research suggests that medical-grade near-infrared light therapy may play a role in protecting the brain from inflammation caused by repeated impacts — a finding with potential implications for athletes, military personnel and others at risk of long-term neurological injury. While still in early stages, this emerging therapy could represent a meaningful advance in brain health and injury prevention. (Medical Xpress)

What Is Near-Infrared Light Therapy?

Near-infrared (NIR) light therapy — sometimes called photobiomodulation — uses specific wavelengths of light that can penetrate the skull and reach brain tissue. Unlike consumer “red-light” devices used for skin health, medical-grade systems are designed to deliver powerful near-infrared light at precise frequencies that may influence cellular activity deep within the brain.

In a recent University of Utah study, researchers tested an intranasal and transcranial NIR device on a small group of collegiate football players over a full 16-week season. Participants were randomly assigned to use either the active NIR therapy device or an identical placebo device that did not emit near-infrared light. (Medical Xpress)

Key Findings from the Study

At the beginning and end of the season, all players underwent MRI brain scans to measure markers of inflammation — a known contributor to long-term brain injury and conditions like chronic traumatic encephalopathy (CTE). The results revealed a striking difference:

• Players using the active near-infrared light therapy showed no significant increase in brain inflammation over the course of the season.

• In contrast, those in the placebo group exhibited a clear increase in inflammation across multiple brain regions.

Lead researchers described the results as “compelling,” especially given the small sample size. Study authors emphasize that while these findings are promising, larger and more rigorous trials are needed to confirm efficacy and better understand the mechanisms involved. 

Why This Matters

Repeated head impacts — even those that don’t cause concussion symptoms — are increasingly linked with long-term neurological disorders, including memory loss, mood changes and cognitive impairment. Preventing or reducing brain inflammation may be a critical step in reducing the risk of these outcomes. 

The current study focused on athletes, but researchers are planning a major follow-up trial involving 300 participants, including veterans, first responders, and others with persistent post-trauma symptoms. This USA Department of Defense-funded study will explore whether NIR therapy can help those with traumatic brain injury (TBI) and concussion.

How Near-Infrared Light May Work

Although the exact mechanism is still being studied, near-infrared light at specific wavelengths is thought to interact with cellular components such as mitochondria, enhancing metabolic activity and reducing inflammation. Previous preclinical research supports the idea that photobiomodulation can influence cellular pathways associated with healing and recovery. (Phys.com)

It’s important to note that this form of therapy differs significantly from over-the-counter red light devices. Medical-grade near-infrared systems use precisely calibrated wavelengths and power levels to target deeper tissues and are designed for clinical research settings. 

What’s Next

While the initial findings are encouraging, NIR therapy remains an emerging technology. Healthcare providers emphasize that more data from larger, controlled trials will be crucial before it becomes a mainstream option for protecting brain health.

For individuals and families affected by concussion or repetitive head injuries, staying informed about advances like near-infrared light therapy offers hope — but it’s equally important to rely on evidence-based prevention strategies and to consult medical professionals about safe treatment options.
