Considering a Red Light Therapy Device in Concussion Recovery? Read This First

If you're exploring red light therapy - a therapy that falls under the larger umbrella of photobiomodulation (PBM) - as a tool in recovery from a concussion or traumatic brain injury (TBI), you're not alone. Increasing numbers of people are turning to red and near-infrared light therapy for its potential to support neuroplasticity, reduce neuroinflammation, and promote cellular repair. While single-modality interventions like PBM can be therapeutic in numerous ways*, they should be used in a larger context of comprehensive concussion care and neuro-rehabilitation.

Not all PBM devices are created equal—especially when it comes to brain health.

Here are 7 essential things to consider before purchasing a PBM device for at home use:

1. Wavelength Selection Is Critical

For brain-related applications, near-infrared (NIR) wavelengths between 810 and 870 nm are often used. Red light (630–660 nm) doesn’t penetrate as deep into tissue as NIR, though it has its own benefits for supporting circulation and overall health.

Look for a device that includes NIR in the 810–850 nm range—this is where most of the clinical research on brain PBM is focused**.

2. Pulsed Light May Offer Additional Benefits

Some PBM studies suggest that pulsed light, particularly in the 10 Hz to 40 Hz range, may be more effective for neurological recovery than continuous-wave light. This frequency range mimics natural brainwave rhythms, possibly enhancing neuroplasticity and cerebral blood flow.

3. Transcranial vs. Intranasal Application

PBM for the brain can be delivered:

· Transcranially (through the scalp and skull)

· Intranasally (through the nasal cavity, which has thin bone and direct vascular access to the brain)

Some users combine both for more comprehensive coverage. Decide which method aligns with your comfort level, goals, and lifestyle, and choose a device accordingly.

4. Thermal Management and Safety

The brain is sensitive. Devices used for TBI should not overheat the scalp or skull. Ensure the product is designed for head use and maintains a safe thermal output.

If you're using a DIY setup, carefully check the guidelines for heat dissipation and wear time. Make sure to follow all instructions closely by any device manufacturer.

5. Clinical Backing and Real-world Results

Look for devices inspired by or directly supported by clinical research on PBM for TBI or concussion. Some home-use models are designed to replicate protocols used in studies. Brain PBM studies are on-going in populations of people with:

• Dementia

• Alzheimer's Disease

• Parkinson's Disease

• Depression

• Traumatic brain injuries***

6. Support, Warranty, and Return Policy

You may need time to determine if a PBM device is suitable for you. Look for:

· At least a 30- to 60-day return window

· A 1–2 year warranty

· Responsive customer support

Some companies even offer consultations or guided protocols—this can be incredibly helpful if you’re new to PBM.

7. Cost vs. Value

PBM devices for brain support range from a few hundred dollars to several thousand. You don’t necessarily need the most expensive model—but ultra-cheap devices may lack critical safety and performance features making them not worth the money.

Ask yourself:

· How long do I plan to use this?

· Is this for brain and neurological support or physical/bodily pain?

· Is this for occasional support or ongoing neurorehabilitation?

· Will I need other people in my household to use it?

Sometimes, spending more upfront can lead to better results with less trial and error.

Healing Is Personal

While PBM isn’t a magic bullet, it’s showing real promise in supporting people in their recovery. Choosing the right device can make a meaningful difference in your healing journey—but it’s essential to be informed and intentional.

Whenever possible, consult with a neurologist or a clinician who is familiar with PBM to ensure you're using the correct settings for your condition. Your brain is worth it.
