Short Answer:
Yes, red light therapy can reduce headache and migraine frequency and intensity by relaxing blood vessels, reducing inflammation, and improving circulation.
It’s non-invasive, drug-free, and may be used as a supportive therapy alongside conventional treatments.
How Red Light Therapy Works for Headaches
Red light therapy uses low-level wavelengths, typically:
-
Red light (630–660 nm): penetrates superficial tissues, helping relax tense muscles.
-
Near-infrared light (810–850 nm): penetrates deeper tissues, including the scalp, neck, and temples.
These wavelengths stimulate cellular energy (ATP) and improve blood flow, which can help:
-
Relax tight muscles — often a cause of tension headaches.
-
Reduce inflammation — lowering oxidative stress and inflammatory markers in blood vessels.
-
Improve circulation — increasing oxygen delivery to tissues and nerves.
-
Calm the nervous system — promoting relaxation and pain relief.
Types of Headaches RLT Can Help
-
Tension headaches — caused by muscle tightness or stress.
-
Migraines — some studies suggest near-infrared light can reduce severity and frequency.
-
Cluster headaches — limited evidence, but RLT may help with pain modulation in some cases.
Note: RLT is less likely to help headaches caused by serious underlying conditions, like stroke or infection. Always consult a doctor if headaches are severe or sudden.
How to Use Red Light Therapy for Headaches
-
Target the affected area: temples, forehead, neck, or back of the head.
-
Session duration: 10–15 minutes.
-
Frequency: 3–5 times per week for prevention; as-needed sessions for acute tension headaches.
-
Device type: Handheld red light therapy devices or panels with 660 nm red + 850 nm near-infrared LEDs.
Tip: Keep your eyes closed or use protective goggles. Use moderate intensity to avoid overheating or discomfort.
Precautions
-
Avoid RLT on open wounds or irritated skin.
-
People with photosensitive conditions or on light-sensitizing medications should consult a doctor.
-
RLT should not replace prescribed headache or migraine medication, but can complement it.
Bottom Line
Red light therapy can help reduce tension, inflammation, and improve circulation, which may ease headaches and migraines for some users.
Professional-grade systems like MERICAN red light therapy beds or panels provide combined 660 nm red + 850 nm near-infrared light, allowing deep penetration to target both surface and underlying tissues for effective pain relief and relaxation.
