Understanding Photobiomodulation (PBM) Technology

Written By Naveen Thomas, MD

Photobiomodulation (PBM) refers to the therapeutic use of certain very specific wavelengths of light (red or near-infrared) to stimulate healing, reduce inflammation, and improve cellular energy production, especially in the brain.  When applied to the scalp,  PBM can penetrate the skull and activate the mitochondria (the cellular power plants  within our neurons, enhancing energy and supporting neuroplasticity.

This technology is currently being explored in clinical research for conditions like Alzheimer’s, cognitive decline, traumatic brain injury, depression, to name just a few.    But even beyond these applications, many users report improvements in mental clarity, sleep quality, and emotional regulation with regular use.

What sets PBM apart is that its benefits occur at the bioenergetic level—helping cells function more efficiently rather than targeting specific neurotransmitters. This makes it especially promising for individuals experiencing neuroinflammation, post-viral syndromes, or brain fog from chronic illness.

Key Benefits of PBM Technology

  1. Enhanced Cognitive Function:

    PBM has been linked to improved cognitive performance, including better memory, focus, and clarity. Studies have shown that the application of near-infrared light can enhance neuronal health and promote neuroplasticity, essential for learning and mental sharpness. Using PBM therapy may provide a significant boost to those looking to improve their cognitive abilities.

  2. Support for Brain Health:

    PBM technology encourages healthy blood flow and oxygenation in the brain. This realignment enhances neurotransmitter activity and supports more robust connections between existing neurons and even offers the possibility of neural regeneration.  This can significantly benefit individuals dealing with age-related cognitive decline or those seeking to maintain optimal brain function.

  3. Reduced Inflammation and Pain Relief:

    Chronic inflammation is at the root of many health issues, from autoimmune diseases to neurodegenerative disorders. PBM can help robustly reduce inflammation, providing relief for various conditions. Many users report significant reductions in pain and discomfort, leading to a better quality of life.

  4. Convenient, User-Friendly, and Non-Invasive:

    One of the standout features of PBM technology is its non-invasive nature. Unlike many medical treatments that require expensive in-office procedures or medications with side effects, PBM devices can be used safely at home. This convenience encourages individuals to integrate it easily into their daily routine.

A Word of Caution and Encouragement

While this technology is promising, it is most effective when integrated into a personalized, holistic plan that includes attention to sleep, nutrition, movement, gut health, and emotional well-being. As with any therapeutic modality, proper guidance and clinical oversight enhance both safety and results.

Dr. Thomas has extensive experience using PBM and is uniquely positioned to educate clients on PBM and evaluate whether PBM is a good fit for your personalized wellness plan.

I have been a practicing psychiatrist for nearly 20 years. I graduated from Emory University in Atlanta, Georgia and completed my medical school training at Emory University School of Medicine. I then went on to complete my post graduate psychiatric residency training at the University of North Carolina in Chapel Hill, North Carolina.

I became interested in the field of holistic/integrative psychiatry after experiencing the ongoing frustrations of the primarily medication-centered approach that I was trained in. Many of my patients were experiencing consistently disappointing results in achieving a state of greater healing and peace, despite significant efforts from all concerned. I began to suspect that the conventional allopathic model of medical and psychiatric care that focuses primarily in symptom reduction had very significant limitations.

I was gradually drawn to the field of integrative psychiatry, which emphasizes a more comprehensive approach that takes into account the profound interconnectedness between mind, body, and spirit and looks to address the root causes of challenging mental health symptoms.

My journey into this field formally began with a Fellowship Program through the University of Arizona Center for Integrative Medicine founded by Dr. Andrew Weill. This program taught me to begin to focusing on optimal nutrition diet, gut health, exercise, and mind/body exercises, to name a just a few.

As I began to start practicing the integrative tools that I learned and helping my patients address the root causes of their symptoms, I was delighted to see that more of my patients were making more meaningful gains in their own healing.

I eventually became certified through the Ketamine Training Center in another very powerful tool called Ketamine Assisted Psychotherapy. I have been consistently amazed at the transformations in the lives of my patients that committed to this process.

I look forward to being your partner on your journey to optimal health.
