Concussions are more than just a bump on the head—they are traumatic brain injuries (TBI) that can have serious consequences if not treated properly. When the brain is injured, it can lead to inflammation, disrupted neural connections, and impaired brain function. This can result in symptoms such as headaches, dizziness, memory issues, mood swings, and even long-term cognitive impairments if left untreated.
Photobiomodulation (PBM), or red light therapy, has emerged as a promising treatment for concussions. Red light wavelengths between 660nm and 850nm—the wavelengths used in red light therapy devices—have been shown to reduce inflammation, stimulate cellular repair, and accelerate brain recovery.
Why are Concussions Harmful?
A concussion occurs when the brain is shaken inside the skull due to a blow or impact. This leads to a temporary disruption of normal brain function, causing symptoms like confusion, memory loss, and even unconsciousness. In severe cases, repeated concussions can lead to long-term brain damage, affecting cognitive abilities, mood, and overall quality of life. The brain's inflammatory response to injury is one of the key factors in the persistence of these symptoms, which is where PBM can be incredibly effective.
Photobiomodulation for Concussions
Top red light therapy panels are designed to deliver optimal wavelengths—660nm (red light) and 850nm (near-infrared light)—for brain health and recovery. These wavelengths are scientifically proven to penetrate deeper into tissues, reaching the brain even when applied through the scalp.
Here’s how red light therapy devices can help:
Reduction of Inflammation: The 850nm near-infrared light penetrates deep into the brain tissue to reduce inflammation, one of the main issues following a concussion. By decreasing neuroinflammation, PBM can help alleviate symptoms like headaches and brain fog.
Cellular Repair: The red and near-infrared light stimulates mitochondria in brain cells, which increases ATP production (cellular energy), facilitating faster repair of damaged brain tissue.
Neurogenesis and Neuroplasticity: Studies show that PBM can stimulate the growth of new neurons (neurogenesis) and promote brain plasticity, helping the brain adapt and recover after injury.
Studies and Research Supporting PBM for Concussions
Several studies have explored the use of PBM for traumatic brain injuries, with positive results:
Naeser et al. (2014): This study examined the effects of near-infrared light on patients with TBI, showing that regular sessions of PBM led to significant improvements in cognitive function and emotional regulation. Participants reported reductions in symptoms such as depression, anxiety, and irritability.
Hamblin (2016): One of the leading researchers in PBM, Michael Hamblin, has extensively studied its effects on brain injuries. His research highlights that red and NIR light can reduce brain inflammation, enhance neuroplasticity, and accelerate recovery from concussions.
Case Studies: There are numerous real-life accounts of athletes and individuals who have recovered from concussions using PBM. For example, former NHL player Sidney Crosby reportedly used photobiomodulation as part of his recovery process after multiple concussions during his career.
Using Red Light Therapy for Concussion Recovery
Wavelength: 660nm and 850nm wavelengths, are the most beneficial for treating concussions. These wavelengths ensure deep penetration, targeting inflamed brain tissue and promoting healing at the cellular level.
Session Duration and Frequency: For optimal results, it’s recommended to use the RLT panel for 10-20 minutes per session, 3-5 times a week. The therapy should be applied consistently over a period of weeks to allow time for the brain to fully recover.
Target Area: Focus the red light on the scalp and forehead, ensuring that the therapy reaches the affected areas of the brain. RLT devices offer powerful light output that can penetrate even thick hair and skull tissue.
Conclusion
Photobiomodulation, particularly when delivered by high-quality devices , offers a non-invasive, drug-free option for supporting recovery from concussions. With the right wavelengths—660nm and 850nm— red light therapy can help reduce brain inflammation, promote cellular repair, and aid in faster recovery from the long-lasting effects of concussions.
For anyone experiencing concussion symptoms or seeking to enhance brain recovery, red light therapy devices offer a scientifically backed solution to regain brain health and overall well-being.
