How Red Light Therapy Affects the Brain
Red light therapy (RLT), or photobiomodulation (PMB), is a cutting-edge biohacking treatment that uses red and near-infrared (NIR) light to boost cellular health, supporting overall wellness.
When absorbed by the skin, red and NIR wavelengths penetrate deeply into tissues, stimulating cellular energy production, reducing inflammation, and promoting repair. Research shows NIR light may be especially effective for mental health, as it penetrates deeply enough to affect brain cells directly. (Source)
The process begins when red and NIR light stimulate mitochondria to produce more ATP (adenosine triphosphate), the energy currency of cells. Increased ATP boosts cerebral metabolism, improves neuroplasticity, and reduces inflammation—key factors in managing depression and anxiety. (Source)
The Benefits of Red Light Therapy for Mental Health
Studies suggest red light therapy offers promising results for treating:
- Major depressive disorder (MDD)
- Anxiety
- Day-to-day stress
- Traumatic brain injuries
Additional Benefits:
- Soothes depression
- Reduces chronic stress
- Eases anxiety
- Promotes remission of despair
How RLT Improves Brain Function
Key Mechanisms of Action:
- Boosts Energy
Red light therapy increases ATP production, energizing cells for optimal functioning. - Balances Circadian Rhythms
RLT supports melatonin regulation, helping to restore natural sleep cycles disrupted by blue light exposure. (Source) - Reduces Inflammation
RLT enhances blood flow and antioxidant defenses, alleviating inflammation that contributes to mental health issues. - Decreases Oxidative Stress
By neutralizing free radicals, RLT minimizes oxidative stress, which can harm cells and accelerate aging. - Supports Neurogenesis and Synaptogenesis
RLT stimulates neuron regeneration and strengthens synaptic connections, enhancing brain health. (Source)
Current Research Supporting RLT for Mental Health
- 2009 Study: Stroke patients with major depression showed significant mood improvements after RLT treatment, with 6 out of 10 patients achieving remission within two weeks. (Source)
- 2015 Case Study: A traumatic brain injury patient experienced reduced depression, anxiety, and insomnia after 20 NIR light sessions over two months. (Source)
- 2018 Study: Patients with major depressive disorder reported antidepressant effects and improved serotonin levels after transcranial NIR light therapy. (Source)
- 2016 Review: Researchers concluded RLT shows promise for treating MDD, anxiety, and suicidal ideation by targeting brain inflammation, oxidative stress, and neurogenesis. (Source)
Dr. Marc Schoen on RLT and Mental Health
Dr. Marc Schoen of UCLA Medical School has over 25 years of experience treating mental health disorders. He says, “Using red light therapy alongside psychotherapy appears to catapult patients out of acute depressive states faster than any other modality.”
Using Red Light Therapy at Home
Sample Application: RLT for Depression
- Device: Model 1 Pro
- Duration: 13 minutes
- Distance: 2 inches from the face
- Wavelength: 850nm (NIR light)
Takeaway
Red light therapy is a promising, non-invasive, drug-free option for managing anxiety and depression. While it shouldn’t replace talk therapy or medication, it offers a safe and accessible method to enhance mental well-being at home.
