Red light therapy (RLT) and near-infrared (NIR) light may offer a promising, drug-free complement to migraine care, particularly when migraines involve muscle tension, inflammatory processes, or pain around the head and neck. Early human studies using NIR wavelengths around 808 to 810 nm have reported fewer migraine or headache days, reduced pain, and less reliance on acute migraine medication. While larger trials are still needed, the research provides useful guidance on which wavelengths and treatment approaches show the most promise.
Red light therapy (RLT), or photobiomodulation (PBM), uses specific wavelengths of red and near-infrared light to influence cellular activity. By potentially supporting cellular function and modulating inflammation, RLT may help relieve some contributors to headaches and migraine discomfort.
Green light therapy offers a different but complementary approach. Unlike red and near-infrared light, which are being investigated for their potential effects on cellular function and pain pathways, narrow-band green light has been studied for its potential to reduce migraine-related pain and light sensitivity.
Key research takeaways
- Red and NIR light may influence several biological processes involved in migraines. A 2026 review highlighted potential effects on mitochondrial function, inflammation, cerebral blood flow, and migraine-related nerve pathways.
- 810 nm NIR therapy may reduce migraine frequency and medication use. A 2024 randomized pilot trial involving 60 people with chronic migraine found fewer monthly migraine days and less acute medication use after eight sessions of NIR laser acupuncture compared with sham treatment.
- 808 nm laser therapy may improve headache frequency and severity. A 2018 trial involving 36 people with chronic migraines reported improvements in headache days, pain intensity, and acute medication use after 10 treatment sessions.
Below, we’ll explain how red light therapy may help, which wavelengths have been studied, how often to use it, and how to approach treatment safely at home. We'll also touch on how it differs from green light therapy for migraines, which uses visible green wavelengths to potentially ease migraine pain and light sensitivity.

Red Light Therapy for Migraines: What We Know So Far
Research on red light therapy for migraines is still emerging, but the results so far point in a useful direction. Near-infrared PBM around 808 to 810 nm has the strongest direct human evidence, with small clinical studies reporting fewer migraine or headache days, less pain, and reduced use of acute migraine medication.
If you're trying red light therapy based on the current migraine research, an NIR-capable device and consistent use over several weeks are the most research-aligned approach. Keep track of migraine days, pain severity, and acute medication use so you can evaluate whether treatment is actually helping.
How Red Light Therapy May Help with Migraines
Red and near-infrared photobiomodulation may help reduce migraine frequency, pain, and reliance on acute medication. Migraines are neurological events involving changes in brain activity, nerve signaling, cellular energy production, inflammation, and blood-flow regulation. These processes can contribute to headache pain, nausea, light sensitivity, and other symptoms that last for hours or days.
Researchers are exploring how red and NIR light may influence several of these processes:
- Pain signaling: During a migraine, the trigeminal nerve carries pain signals from the head and face to the brain. Photobiomodulation may help regulate inflammation and nerve activity that contribute to heightened pain sensitivity.
- Cellular energy: Migraine has been linked to problems with how brain cells produce energy. Photobiomodulation may support mitochondria (the structures that produce cellular energy) and ATP production, potentially helping brain cells function more efficiently.
- Inflammation: Inflammatory signals around nerves and other brain tissues can contribute to migraine pain and sensitivity. Photobiomodulation may help regulate these signals and reduce cellular stress.
- Brain activity and blood flow: Migraines can involve changes in brain activity and how blood flow responds to the brain's needs. Photobiomodulation may influence circulation and the processes that help match blood supply to brain activity.
These mechanisms offer possible explanations for the benefits observed in early studies, although researchers haven't established exactly how photobiomodulation produces migraine relief.
| Potential Benefit | What the Research Suggests | What This Could Mean for Migraines |
|---|---|---|
| Fewer migraine attacks | Small human studies using 808–810 nm NIR have reported reductions in monthly migraine or headache days. | May help reduce how often migraines occur with regular treatment |
| Reduced migraine pain | Human studies have reported improvements in headache intensity following NIR treatment. | May help make migraine attacks less painful and easier to manage |
| Less reliance on acute medication | Some clinical studies have reported reduced use of medications taken during migraine attacks. | May help reduce the need for rescue medication when migraine symptoms improve |
1. May Reduce Migraine Frequency
NIR photobiomodulation may help reduce how often migraine attacks occur. Researchers believe its potential effects on cellular energy production and brain activity could be relevant to migraine prevention. Mitochondria produce adenosine triphosphate (ATP), the energy cells need to function, and problems with this process have been linked to migraine susceptibility.
A 2024 randomized pilot trial involving 60 people with chronic migraine found that eight sessions of 810 nm NIR laser acupuncture over four weeks reduced monthly migraine days compared with sham treatment. A 2018 study involving 36 people with chronic migraine also reported fewer headache days following 10 sessions of 808 nm low-level laser therapy (LLLT).
2. May Reduce Migraine Pain and Sensitivity
Red and NIR light may help reduce migraine pain by influencing inflammation and the nerve pathways involved in pain signaling. During an attack, inflammatory signals can increase activity in the trigeminal nerve, which carries pain signals from the head and face to the brain. PBM may help regulate these signals and reduce cellular stress, potentially easing pain and sensitivity.
The 2018 study reported reductions in headache intensity following 808 nm laser therapy. A 2026 review also identified inflammation, nerve signaling, and blood-flow regulation as possible pathways through which photobiomodulation could influence migraine symptoms. However, these mechanisms remain under investigation.
3. May Reduce Reliance on Acute Migraine Medication
NIR therapy may help some people reduce their use of acute migraine medication if their attacks become less frequent or severe. This is a potential secondary benefit of improved migraine control rather than a separate biological effect of photobiomodulation.
Both the 2024 randomized pilot trial and the 2018 study reported reductions in acute medication use following NIR treatment. These findings are encouraging, but they don't mean patients should reduce or discontinue prescribed medication without consulting their healthcare provider.
It's also important to distinguish clinical treatments from at-home devices. The human studies above used controlled laser-based protocols, including laser acupuncture. Home LED devices may differ in wavelength, power, placement, and delivered dose, so the same results aren't guaranteed. A 2022 systematic review found promising results for some primary headache outcomes but rated the overall evidence as very low certainty.

Red vs. Near-Infrared (NIR) vs. Green Light for Migraines
Near-infrared (NIR) and green light therapy are both being studied for migraine relief, while visible red light has less direct migraine-specific research than either approach.
| Red Light | Near-Infrared Light (NIR) | Green Light | |
|---|---|---|---|
| Typical range | 630–660 nm | 808–810 nm | 520–530 nm |
| What it looks like | Yes, red | No | Yes, green |
| How it’s used | Applied to the body, penetrates superficial tissues | Applied to the body, penetrates deeper tissues | Experienced visually, stimulates visual pathways |
| Primary research focus | Cellular function and pain pathways | Cellular energy, inflammatory processes, and pain pathways | Visual processing, light sensitivity, and migraine pain |
| Direct migraine evidence | Limited | More promising human evidence, particularly around 808–810 nm | Human studies suggest potential improvements in pain, light sensitivity, headache frequency, and quality of life |
| Practical takeaway | Not the first choice based on migraine research alone | The more research-aligned choice for migraine support | A promising, research-backed option for migraine relief |
The biggest difference between these approaches is how the light is delivered and which biological systems researchers are investigating. Red and near-infrared photobiomodulation (PBM) typically involves directing light toward the skin or underlying tissues to influence cellular activity, while green light therapy for migraines is generally studied through controlled visual exposure, where light is perceived by the eyes and processed by the brain.
This distinction matters because green light isn't primarily being studied as a way to deliver light energy into deeper tissues. Instead, researchers are investigating whether certain green wavelengths may be less disruptive to people with migraine-related light sensitivity and may influence the visual and neurological pathways involved in migraine pain.
Red and NIR light are being investigated for their potential effects on cellular energy production, inflammatory signaling, and pain pathways. The strongest migraine-specific NIR findings to date include studies using wavelengths around 808–810 nm. These results are encouraging, but they don't establish that this range is uniquely effective or that other wavelengths, such as 830 nm or 850 nm, provide equivalent benefits.
If you're considering light therapy for migraines, the best choice depends on your treatment goals. NIR has promising evidence for reducing migraine frequency and severity through repeated treatment, while green light has been studied for both symptom relief during attacks and improvements with consistent use. Visible red light has less direct evidence for migraines.
For a closer look at the research, treatment protocols, and potential benefits of green wavelengths, read our guide to green light therapy for migraines.
How to Use Red Light Therapy for Migraines
For at-home migraine support, the research points toward near-infrared light used consistently over several weeks rather than only when an attack begins. Your device's instructions should determine the exact treatment time, distance, and frequency.
- Choose a device with near-infrared light. Migraine studies showing benefits have primarily used 808 to 810 nm NIR. At-home devices commonly use nearby wavelengths such as 830 nm or 850 nm; these are within the NIR range, although they haven't been studied as directly for migraines.
- Treat targeted areas of the head. Clinical studies have applied PBM to different points around the head, including the forehead, temples, and other cranial areas. Because laser acupuncture and transcranial PBM deliver light differently from at-home devices, use the placement recommended for your specific device rather than trying to recreate a clinical protocol.
- Stick to the recommended treatment time and distance. Light dose depends on the device's output, treatment time, and distance from the skin. A 20-minute session with one device isn't necessarily equivalent to 20 minutes with another, so copying session times from a clinical study can deliver too much or too little light.
- Use it consistently rather than waiting for a migraine. Studies reporting improvements generally used PBM 2 to 3 times per week for about 4 to 5 weeks. That provides a useful research-based reference point, but follow your device's recommended frequency since the amount of light delivered can vary considerably between devices.
- Track your results. Record migraine days, pain severity, attack duration, and how often you need acute migraine medication. After several weeks, these measures can give you a clearer picture of whether red light therapy is making a meaningful difference.
If light tends to aggravate your migraines, don't push through worsening symptoms just to complete a session. Shortening or stopping treatment and discussing persistent sensitivity with a healthcare provider is more appropriate than increasing exposure.

How Long Does Red Light Therapy Take to Work for Migraines?
Don't judge whether red light therapy is helping your migraines after one or two sessions. The human studies showing benefits used repeated treatments over several weeks, making about 4 to 5 weeks of consistent use a more useful first evaluation point.
| Timeframe | What to Expect |
|---|---|
| First few sessions | Immediate migraine relief hasn't been well established. RLT is better supported as an ongoing approach than as a treatment for stopping an acute migraine attack. |
| Around 4–5 weeks | This matches the treatment period used in key 808–810 nm NIR studies, which reported improvements in migraine or headache days, pain, and acute medication use. |
| Around 8–12 weeks | In the 2024 chronic migraine trial, researchers continued measuring outcomes at weeks 8 and 12 and found that improvements in monthly migraine days remained measurable during follow-up. |
| Long term | Research hasn't yet established how long benefits may last or whether ongoing maintenance sessions are needed. |
Rather than looking for an immediate change after each session, compare your migraine patterns over several weeks. Tracking migraine days, pain severity, attack duration, and medication use can help you determine whether treatment is making a meaningful difference.
Red Light Therapy vs. Other Migraine Treatments
Red light therapy (RLT) is best viewed as a complementary migraine treatment rather than a replacement for established care. Current evidence is most relevant to ongoing migraine management, while medications and other treatments may have different roles in preventing or stopping attacks.
| Treatment | How It Helps with Migraines | How It Fits with RLT |
|---|---|---|
| Preventive migraine medication | Taken regularly to reduce how often migraines occur and, in some cases, their severity | RLT may be explored alongside preventive treatment, but shouldn't replace prescribed medication without guidance from your healthcare provider. |
| Acute migraine medication | Treatments such as triptans and newer migraine-specific medications are used to relieve symptoms once an attack begins. | RLT hasn't been established as an equivalent rescue treatment and may be better suited to ongoing management. |
| Botox | For certain people with chronic migraine, Botox injections can reduce the number of headache and migraine days. | RLT may complement Botox as part of an ongoing migraine-management plan because the two use different approaches. A small 2018 study also directly compared 808 nm low-level laser therapy with Botox, with improvements reported in both groups. |
| Lifestyle and trigger management | Regular sleep, hydration, meals, stress management, and identifying migraine triggers can help reduce attacks for some people. | These strategies can continue alongside RLT and provide a broader approach to migraine management. |
| Green light therapy | Uses controlled exposure to visible green light and is being heavily studied for migraine pain and light sensitivity | Green light therapy and RLT may complement each other because they use different wavelengths and treatment approaches. |
The right approach depends on whether you need prevention, relief during an acute migraine, or both. Red light therapy currently fits more naturally into the preventive or complementary side of migraine management because the most promising studies used repeated treatments over several weeks. Green light therapy is another promising light-based approach, but the goal and method are different.
Red Light Therapy Side Effects and Safety for Migraines
Red and near-infrared PBM is generally well tolerated, but people with migraines may need to be especially careful about light sensitivity. Bright or uncomfortable light can trigger or worsen symptoms for some people, particularly during an active migraine attack.
Potential side effects are usually mild and may include temporary:
- Headache or worsening migraine symptoms
- Eye discomfort or visual sensitivity
- Warmth or skin irritation at the treatment area
- Dizziness or discomfort during treatment
To use red light therapy more safely:
- Follow your device's eye-safety instructions. Don't stare directly into LEDs or lasers, and use protective eyewear when recommended.
- Start conservatively if you're sensitive to light. Shorter sessions may help you determine how you respond before increasing exposure according to your device's instructions.
- Stop if treatment consistently makes your migraines worse. Increasing exposure isn't likely to help if light itself is aggravating your symptoms.
- Check medications for light sensitivity. Some medications can make the skin or eyes more sensitive to light. Ask your healthcare provider or pharmacist if you're unsure whether this applies to a medication you take.
- Talk with your healthcare provider if you have frequent or severe migraines. Red light therapy should complement appropriate migraine care rather than delay evaluation or prescribed treatment.
When a Headache Needs Medical Attention
Some headaches need prompt medical evaluation rather than at-home treatment. Seek medical care for a sudden, extremely severe headache; new weakness, numbness, confusion, trouble speaking, or vision changes; a severe headache following a head injury; or a headache that's significantly different from your usual migraine pattern. Red light therapy shouldn't be used to delay medical care for new, rapidly worsening, or otherwise concerning headache symptoms.
