Red Light & Near-Infrared Therapy for Concussions & Head Injury Recovery
Red and near-infrared light therapy—also known as photobiomodulation—is emerging as a promising treatment for concussions and brain injuries. By boosting cellular energy, improving blood flow, and reducing inflammation, red light helps the brain recover naturally after trauma. Clinical studies from institutions like Mass General Hospital and JAMA Network show it can improve brain connectivity, memory, and mood following head injuries.

How Red Light & Near-Infrared Therapy Can Optimize Pre-Op and Post-Op Surgical Recovery
Red and near-infrared light therapy (often called photobiomodulation) can be a powerful ally before and after surgery. By boosting cellular energy, improving circulation, and reducing inflammation, this safe, non-invasive treatment helps your body recover faster, with less pain and smoother healing. When used pre-surgery, it “preconditions” tissues for better resilience, and post-surgery it supports faster wound repair and scar reduction.

Red and Near-Infrared to help Nerve Regeneration
Nerve damage is one of the most challenging conditions to treat. Whether caused by injury, surgery, diabetes, or chronic illnesses, damage to peripheral nerves often leads to pain, numbness, tingling, and impaired function. Unlike skin or muscle, nerve tissue regenerates very slowly, and in some cases, healing is incomplete. Traditional treatments often focus on managing symptoms rather than repairing the underlying damage. In recent years, however, there has been growing interest in a non-invasive approach that may support the body’s ability to repair nerve tissue: red and near-infrared (NIR) light therapy, also known as photobiomodulation (PBM). Studies are beginning to show that PBM can stimulate cellular repair processes, improve circulation, and enhance recovery in nerve-related conditions. So, how does this work — and what does the science say? How Red and Near-Infrared Light Affect Nerve Cells Both red light (around 630–660 nm) and near-infrared light (around 810–850 nm) penetrate tissues and are absorbed by mitochondria, the “powerhouses” of cells. Specifically, they target an enzyme called cytochrome c oxidase, which is part of the mitochondrial respiratory chain. When stimulated by these wavelengths, mitochondria produce more ATP (adenosine triphosphate) — the energy currency of the cell (NIH). In nerve cells, this extra energy allows for: Axonal repair: Damaged axons (the long projections of neurons) can regrow when energy demands are met. Myelin regeneration: Light therapy may support the repair of myelin, the protective sheath around nerves that is critical for fast and accurate signal transmission. Protein synthesis: Increased ATP fuels the creation of structural proteins needed for nerve repair. In short, light therapy helps “recharge” injured nerves so they can carry out the demanding process of repair. Reducing Oxidative Stress and Inflammation Nerve injury often creates an environment of oxidative stress, where excessive reactive oxygen species (ROS) damage cellular components. Photobiomodulation helps normalize ROS levels by making mitochondria more efficient. This not only protects neurons but also reduces secondary damage that can occur after the initial injury. In addition, light therapy reduces inflammatory cytokines — signalling proteins that can prolong pain and impair healing. By calming the inflammatory response, PBM creates a more favorable environment for regeneration. Research in the Journal of Neurotrauma found that NIR therapy not only reduced oxidative stress but also improved functional recovery after nerve injury (PubMed). Stimulating Neurotrophic Factors One of the most promising findings is that red and NIR light increase levels of neurotrophic factors. These are proteins that guide nerve growth, survival, and function. Among the most important are: Nerve Growth Factor (NGF): Promotes survival and growth of sensory and sympathetic neurons. Brain-Derived Neurotrophic Factor (BDNF): Supports synaptic plasticity, learning, and repair. A study published in Neuroscience Letters found that PBM increased expression of BDNF and NGF in animal models, leading to enhanced axon regeneration and functional recovery (NIH). This means that light therapy doesn’t just provide energy; it also helps activate the genetic and molecular programs necessary for nerves to rebuild themselves. Improving Circulation and Nutrient Delivery Nerves, especially peripheral nerves, have limited blood supply compared to other tissues. Poor circulation can slow healing and leave damaged nerves starved of oxygen and nutrients. Near-infrared light penetrates deeper than red light and stimulates nitric oxide release, which relaxes blood vessels and improves microcirculation. A study in Lasers in Surgery and Medicine demonstrated that animals treated with NIR after nerve injury had faster functional recovery and improved nerve conduction velocity compared to controls (PubMed). Improved blood flow is key not only for repair but also for clearing out metabolic waste products that accumulate in injured tissues. Evidence from Clinical and Preclinical Studies While much of the research has been done in animal models, the results are encouraging - and early human studies are beginning to confirm the benefits. Peripheral nerve injury: Animal studies show that PBM accelerates axonal regrowth and improves recovery of motor and sensory function. Carpal tunnel syndrome: Clinical trials using NIR light have reported reductions in pain and improvements in grip strength and nerve conduction (PubMed). Diabetic neuropathy: Studies suggest that PBM reduces pain and numbness while improving quality of life for patients with diabetic nerve damage. Post-surgical nerve recovery: Patients treated with red/NIR light after surgery have shown reduced pain, less inflammation, and better long-term functional outcomes. Although more large-scale clinical trials are needed, the existing data strongly suggest that photobiomodulation is a safe and effective adjunct therapy for nerve regeneration. What Patients Report Beyond the lab, many people using red and near-infrared therapy devices report improvements such as: Reduced tingling and numbness Decreased nerve pain Improved muscle activation in affected areas Better coordination and grip strength While individual results vary, these reports align with the physiological mechanisms demonstrated in research. Suggested Protocol for Nerve Regeneration (Using the Kivo Elite Panel) If you are considering red and NIR light therapy at home, consistency is key. Nerve healing is slow, and results are usually seen over weeks to months. A commonly recommended protocol is: Wavelength: Red + Near-Infrared Brightness: High (Level 5 on Kivo Elite Panel) Pulse: 40 Hz (associated with neurological repair and brain wave entrainment) Duration: 15–20 minutes per affected area Frequency: 5–7 times per week Treatment Length: At least 8–12 weeks, longer for chronic conditions This can be used alongside conventional treatments such as physical therapy, medications, and lifestyle interventions. Always consult a healthcare provider before starting new therapies, especially if you have a medical condition.

Traditional medicine often offers limited solutions beyond pain relief. Light therapy represents a shift — instead of masking symptoms, it seeks to help the body heal itself. As the research base expands, red and near-infrared therapy may become a standard part of nerve rehabilitation protocols, both in clinics and at home. Devices like the Kivo Elite Panel make it possible to access this promising therapy safely and consistently. For those dealing with nerve injuries, neuropathy, or post-surgical recovery, photobiomodulation offers real hope: faster healing, less pain, and a better chance of regaining function.

3 minutes of red light therapy can improve a person’s vision
Clinical Overview: 3 minute morning exposure to Red Light improves eyesight Introduction Mitochondrial dysfunction has emerged as a core mechanism behind many aging-related changes in physiology, including progressive visual decline. Recent research from University College London (UCL) suggests that targeted exposure to deep red light—specifically at 670 nm—may partially restore mitochondrial function in human photoreceptors. In this article, we explore the study’s design and findings in detail, discuss mitochondrial bioenergetics in ocular tissues, and offer evidence-based recommendations for implementing red light therapy at home. We also link findings to Kivo’s red light products, which are designed to meet these parameters. The Role of Mitochondria in Retinal Aging Bioenergetic Demand of Photoreceptors The retina, particularly its photoreceptors (rods and cones), has one of the highest metabolic rates of any tissue in the human body. It requires continuous ATP generation for visual signal transduction, synaptic transmission, and photopigment regeneration. As humans age, mitochondrial respiration declines, ATP production drops, and reactive oxygen species (ROS) increase. This results in impaired photoreceptor function and a decline in both scotopic (night) and photopic (daylight/color) vision. Mitochondrial Decline After Age 40 Multiple studies have shown a steep decline in retinal mitochondrial efficiency by midlife, with some estimates suggesting a 70% reduction in ATP output by age 70. This bioenergetic shortfall correlates with clinical observations of diminished visual contrast, color discrimination, and visual acuity in aging adults. The UCL Study: Design, Exposure Protocol, and Results Study Design Published in Scientific Reports and summarized by Ophthalmology Times, the UCL study was led by Professor Glen Jeffery and investigated the effects of short-duration exposure to 670 nm deep red light on color contrast sensitivity in healthy adults aged 34–70. Sample: 20 participants, both male and female Age range: 34–70 Inclusion criteria: No history of ocular pathology, normal baseline visual function Exposure Parameters Wavelength: 670 nanometers Duration: 3 minutes Frequency: Once per week Intensity: ~8 mW/cm² (non-thermal, well below phototoxicity thresholds) Time of day: Morning (between 8–9 AM) This low-level exposure does not damage retinal tissue, nor does it induce photobleaching. It instead serves to stimulate cytochrome c oxidase, the terminal enzyme in mitochondrial complex IV, enhancing ATP synthesis. Outcome Measures The primary outcome was color contrast sensitivity, assessed using standardized clinical tests. Measurements were taken: Baseline: Before red light exposure Post-Exposure: 3 hours after exposure Follow-Up: 1 week after exposure Key Results Average improvement in color contrast sensitivity: ~17% Maximum improvement in older subjects: ~20% Effect duration: Sustained at least 7 days Afternoon exposure (12–1 PM): No measurable benefit These results reinforce previous findings that retinal mitochondria exhibit diurnal variation in responsiveness, with higher red-light sensitivity in the morning. Clinical Insight: This is consistent with circadian control of mitochondrial respiration, likely modulated by the retinal suprachiasmatic input pathway. Mechanism of Action: How 670 nm Light Affects Mitochondria Cytochrome c Oxidase Activation 670 nm red light falls within the photobiomodulation window (600–900 nm). This range penetrates tissue efficiently and is absorbed by cytochrome c oxidase. The result is: Increased electron transport Enhanced mitochondrial membrane potential Higher ATP output Reduced oxidative stress markers Specificity to Morning Exposure Morning responsiveness likely results from circadian upregulation of cytochrome c oxidase activity. Additionally, retinal mitochondrial respiration peaks earlier in the day, suggesting a time-of-day–dependent therapeutic window. Clinical Implications for Home Use Safety Profile The intensity used (~8 mW/cm²) is far below retinal phototoxicity thresholds. No adverse events were reported. However, guidance on eye safety is essential for home users. Refer to Is Red Light Therapy Safe for Your Eyes?, which outlines proper usage and protective eyewear considerations. Exposure Timing and Duration Ideal timing: 8–9 AM local time Duration: 3 minutes per week Distance: 30–50 cm from the device This matches the protocol used in the UCL study.

Larger, multicenter randomized controlled trials (RCTs) are required to validate findings and assess long-term benefit. Objective Measures Future research may employ ERG (electroretinography), optical coherence tomography (OCT), and molecular biomarkers to quantify mitochondrial recovery and correlate it with functional vision gains. Disease-Specific Application While this study targeted normal aging, red light therapy is under investigation for conditions such as: Age-related macular degeneration (AMD) Diabetic retinopathy Glaucoma Initial findings suggest possible benefit in early-stage AMD, but these applications remain investigational.
