Shedding Light on Healing

Transcranial Photobiomodulation and Head Injuries

Head injuries, whether mild concussions or more severe traumatic brain injuries, can have a profound impact on one’s life. However, a cutting-edge therapy known as transcranial photobiomodulation is offering new hope for recovery and healing. In this blog, we’ll explore what transcranial photobiomodulation is and how it can aid in the recovery process for head injuries.

What is Transcranial Photobiomodulation?

Transcranial photobiomodulation, often referred to as PBM or low-level laser therapy (LLLT), is a non-invasive treatment that utilizes specific wavelengths of light to stimulate cellular functions. In the context of head injuries, it involves applying near-infrared light to the scalp, allowing it to penetrate the skull and reach the brain tissue beneath.

How Transcranial Photobiomodulation Works

Transcranial photobiomodulation works by harnessing the power of light to enhance cellular processes within the brain. Here’s how it works and why it’s relevant for head injuries:

Mitochondrial Stimulation: The near-infrared light used in PBM directly interacts with the mitochondria within brain cells. Mitochondria are often called the cell’s “powerhouses” because they produce energy in the form of adenosine triphosphate (ATP). When exposed to this light, mitochondrial function is optimized, leading to increased ATP production.

Enhanced Blood Flow: PBM has been shown to improve blood flow in the brain. This is vital for delivering essential nutrients and oxygen to damaged brain tissue, promoting healing and reducing inflammation.

Reduced Oxidative Stress: Head injuries often result in increased oxidative stress, which can lead to further damage. PBM helps mitigate oxidative stress and reduce cellular damage, supporting the recovery process.

Neuroprotection: PBM has demonstrated the ability to protect neurons and brain tissue from damage, which is especially important in the context of traumatic brain injuries.

Anti-Inflammatory Effects: PBM has anti-inflammatory properties that can help reduce the inflammation associated with head injuries, contributing to a faster recovery.

How Transcranial Photobiomodulation Helps with Head Injuries

Transcranial photobiomodulation can be a valuable tool in the treatment and recovery of head injuries for several reasons:

Faster Healing: By enhancing blood flow, optimizing cellular energy production, and reducing oxidative stress, PBM can expedite the healing process of brain injuries.

Reduced Symptoms: PBM has been shown to help alleviate some of the common symptoms associated with head injuries, such as headaches, cognitive impairments, and mood disturbances.

Neuroprotection: PBM can help protect brain tissue from further damage, potentially limiting the long-term consequences of head injuries.

Non-Invasive and Safe: Transcranial photobiomodulation is non-invasive, painless, and has a minimal risk of side effects, making it a safe and accessible option for individuals with head injuries.

Adjunct to Other Therapies: PBM can complement other rehabilitation and therapy approaches, such as physical therapy and cognitive therapy, to enhance overall recovery outcomes.


Transcranial photobiomodulation is a promising and innovative therapy that has the potential to significantly improve the recovery process for head injuries. By harnessing the power of light to stimulate cellular functions and support the healing of damaged brain tissue, PBM offers new hope for those navigating the challenges of head injuries. While more research is needed to fully understand its long-term effects, transcranial photobiomodulation is a valuable addition to the toolkit of therapies for head injury rehabilitation and recovery.
