AI Search Summary
This video explains a small study testing green light exposure for fibromyalgia pain after related migraine work. Participants used white LED and green LED periods, spending one to two hours per day in a room lit only by the LEDs. The transcript reports that green light reduced average pain from 8.4 out of 10 to 4.9 out of 10.
- Main question: Can green light help alleviate fibromyalgia pain?
- Short answer / core takeaway: Early evidence suggests green light may reduce fibromyalgia pain for some people, but the creator emphasizes that the study was small and the research is still early.
- Evidence type: Fibromyalgia treatment explainer with DOI-linked green-light pain study.
- Search topics: green light fibromyalgia, chronic pain green light, fibromyalgia LED therapy, migraine protocol, endogenous opioids, retina brain electrical activity, diffuse green lighting.
Common Search Questions
What was the green-light fibromyalgia protocol?
Participants spent one to two hours per day in a room with no other light source, sitting three to six feet from the LEDs, keeping them in view without staring directly at them.
How much did pain change in the study?
The transcript says average pain dropped from 8.4 out of 10 to 4.9 out of 10 during the green LED period.
Why might green light help pain?
The video says green light may produce lower electrical activity in the retina and brain than blue or red light, and may also trigger the brain’s natural opioid production.
Key Takeaways
- This is framed as early-stage research with a small sample of 21 people.
- Participants had fibromyalgia that medication had failed to help.
- The protocol mirrors the migraine green-light protocol: dim, indirect exposure for one to two hours daily.
- The creator says effects were slightly higher for people who did more than 1.5 hours per day.
- The caption notes that many multicolor LED devices can produce the right color at 100% green.
- The caption warns against very cheap or sketchy devices because invisible flicker can cause headaches.
- The caption suggests diffuse lighting may be better than directly visible LEDs or a single small lamp.

Testing green light beyond migraine
Can green light help fibromyalgia?
After using it to treat migraines, which we covered recently, the researchers wanted to see if its pain-reducing effect was more general.
They recruited 21 people with fibromyalgia that medication had failed to help.
Small study, but it’s a start.
Study setup
They gave them each strips of white LEDs and green LEDs.
They were told to spend one to two hours per day sitting in a room with no other light source but those LEDs.
They were to sit three to six feet away, keep the LEDs in view, but not stare directly at them, just like the migraine protocol.
They did 10 weeks on the white LEDs, took two weeks off, and then did 10 weeks on the green LEDs.
Pain results
The green LED light group had their pain drop from an average of 8.4 out of 10 to 4.9 out of 10, with a slightly higher effect for those who did more than 1.5 hours per day.
A lot.
Possible mechanisms
This research is still in its very early stage, but we think it works both because green light produces lower electrical activity in the retina and brain compared to blue or red, and through a totally separate path where green light seems to trigger the brain’s natural opioid production.
Low-cost appeal and next topics
What I love about this is that it’s super low cost and low risk to try yourself, which might make it worth it even though the science is still getting there.
Soon we’ll be covering how this relates to nature exposure, if green glasses work, and a lot more.
Additional Notes
Replying to @RFK Jr.’s Brain Worm. The caption says this may be a weird way to help chronic pain, but it is low cost enough to consider trying.
The creator says they have been testing many green lights, and that more than 80% of multicolor LED devices produce the right color when set to 100% green. The caption warns against very cheap or sketchy brands because they are more likely to have invisible flicker, which can cause headaches.
The caption also says diffuse lighting is probably better than directly visible LEDs, and a more spread-out source may be better than a single small lamp. A complete light review is in progress but delayed due to a software issue with the light meter.
