Concussions affect approximately 1.6-3.8 million Americans annually according to the CDC, with many experiencing persistent symptoms that can last for months or even years. As researchers explore innovative approaches to brain injury recovery, red light therapy (RLT) has emerged as a promising non-invasive treatment option. This article examines the science behind using red light therapy for concussion recovery and how specific wavelengths of light may help heal the injured brain.
How Red Light Therapy Works for Brain Injury
Red light therapy, also known as photobiomodulation (PBM) or low-level laser therapy (LLLT), uses specific wavelengths of red and near-infrared light to stimulate cellular healing. When applied to the head, these wavelengths can penetrate the skull and reach brain tissue, where they interact with the mitochondria—the powerhouses of our cells.
The primary mechanism involves cytochrome c oxidase, an enzyme in the mitochondria that absorbs red and near-infrared light. This absorption increases adenosine triphosphate (ATP) production, providing more energy for cellular repair and reducing inflammation in damaged brain tissue. For concussion patients, this can potentially accelerate recovery and reduce persistent symptoms.
Key Benefits for Concussion Recovery
- Increased cerebral blood flow to injured areas
- Reduced neuroinflammation
- Enhanced mitochondrial function
- Improved cognitive performance
- Decreased oxidative stress
- Potential neurogenesis (formation of new neurons)
Common Concussion Symptoms Addressed
- Persistent headaches
- Brain fog and concentration issues
- Memory problems
- Sleep disturbances
- Mood changes and irritability
- Visual disturbances
Clinical Evidence for Red Light Therapy and Concussion
Several human clinical studies have demonstrated promising results for red light therapy in treating traumatic brain injuries and concussions. Here are three key studies:
Naeser et al. (2014)
This landmark study published in the Journal of Neurotrauma showed significant improvements in cognitive function among chronic mild traumatic brain injury patients after red/near-infrared LED treatments. Participants showed improved executive function, verbal learning, and memory after 18 treatment sessions.
Hipskind et al. (2018)
Researchers found that patients with persistent symptoms from traumatic brain injuries showed improved cerebral blood flow and cognitive function after 18 sessions of near-infrared light therapy. The improvements were both statistically and clinically significant.
Saltmarche et al. (2017)
This study demonstrated improved cognitive function, better sleep, and reduced PTSD symptoms in patients with chronic traumatic brain injury after transcranial and intranasal near-infrared light therapy, with benefits persisting at 12-week follow-up.
These studies collectively suggest that red light therapy can help improve cognitive function, reduce inflammation, and enhance quality of life for those suffering from concussion symptoms, even months or years after the initial injury.
Optimal Wavelengths for Neurological Healing
Not all red light is created equal when it comes to treating brain injuries. Research indicates that specific wavelengths penetrate the skull more effectively and provide optimal benefits for neurological healing:
Most Effective Wavelengths
- 808-810 nm: Penetrates deeply into brain tissue and has shown significant effects in multiple clinical studies
- 830 nm: Excellent penetration with strong mitochondrial stimulation
- 850 nm: Effective for deeper brain structures
- 1064 nm: Deepest penetration, reaching structures throughout the brain
- 633-660 nm: Less penetration but beneficial for surface brain areas and systemic effects
Dr. Michael Hamblin, a former Harvard researcher and leading expert in photobiomodulation, notes that the combination of red (633-660 nm) and near-infrared wavelengths (808-1064 nm) may provide synergistic benefits for brain healing, addressing both surface and deep brain structures simultaneously.
Comparing Red Light Therapy Devices for Concussion Recovery
When selecting a red light therapy device for concussion recovery, several key specifications determine effectiveness:
