AI Search Summary
This video gives practical guidance for trying green light exposure for migraines or fibromyalgia without buying expensive branded devices. It explains why ordinary pure-green LED strips may match the relevant wavelength range used in studies, warns against broad-spectrum party lights or phone apps, and gives instructions for dim, indirect, daily exposure.
- Main question: How can green light therapy be used to treat migraines and fibromyalgia effectively?
- Short answer / core takeaway: The creator says the research is early, but a low-cost setup can be tried with dim pure-green LEDs, no other light sources, eyes open, and one to two hours per day.
- Evidence type: Practical treatment-guidance explainer based on prior green-light migraine/fibromyalgia studies and device/wavelength discussion.
- Search topics: green light therapy at home, migraine green LEDs, fibromyalgia green light, 520 nm light, 525 nm LEDs, migraine device marketing, dimmable LED strips.
Common Search Questions
Do you need an expensive green light migraine device?
The video argues no. It says the patented band of light used by some devices is not special, and that cheap pure-green LEDs often fall in the same wavelength range.
What wavelength of green light is discussed?
The transcript mentions a device around 520 nanometers and notes that the original migraine study used basic 525 nanometer LEDs.
How should green light be used according to the video?
The creator says to sit in a room with no other light sources, keep the green light dim like a nightlight, sit three to six feet away, keep it in the field of view without looking directly at it, and use it one to two hours per day.
Key Takeaways
- Green light treatment is described as early-stage but low cost.
- The transcript says daily green light treatment cut migraine frequency by more than half in a prior study.
- A fibromyalgia study is described as lowering average pain intensity, frequency, duration, and improving sleep and chores.
- The creator criticizes expensive branded green light devices as potential marketing hype.
- Pure green LED strips may be enough if they provide the right narrow wavelength range.
- Generic green bulbs, party lights, and phone apps may not be equivalent because they can emit broader bands of light.
- Flickering from cheap dimming electronics may trigger headaches for some people.
Transcript
Low-cost green light treatment
Here’s exactly how to use green light to treat migraines or fibromyalgia without breaking the bank.
It’s not this.
Last time we covered a study where daily green light treatment cut migraine frequency by more than half. It can also make them less intense.
This fibromyalgia study showed that it lowered average pain intensity, frequency, and duration, as well as improved sleep and the ability to do chores.
Device marketing and wavelength claims
So of course these spawned a bunch of companies rushing to sell you green light migraine relief devices, like this $239 one claiming to use a patented band of light.
Now, I’m no patent attorney, but I am a scientist on a mission to rescue your wallet from marketing hype.
And here’s a little secret: that patented band of light is nothing special.
Light’s wavelength is like a unique color swatch label. One number equals exactly one color.
Sunlight gives you all at once, i.e. white light. Artificial lights give you different ranges. LEDs produce super narrow bands around specific wavelengths.
These guys intentionally didn’t say their wavelength, but this study using it said that it’s around 520 nanometers.
Why cheap green LEDs may match the study range
And how did they come up with this?
The original study on migraines used these basic 525 nanometer LEDs, because all cheap green LEDs are in this range. They’re made with indium gallium nitride, which does not efficiently emit light above 530 nanometers.
No study has even tested other greens.
If you buy a pure LED green light, it’ll likely be the right color. But look for a listed wavelength.
Do not use generic green-colored light bulbs with party lights or apps on your phone, because those are often broader bands of not-pure green.
Brightness and flicker cautions
You do not want something super high-powered. The challenge is actually getting it dim enough.
The migraine study actually covered two out of three LEDs on their strip with electrical tape just to get it dim enough.
You can use multicolored dimmable LED strips set to green, but be careful because the cheaper ones dim by rapidly flickering on and off, which can cause headaches.
I got these for $13, which I’ll link to. They also have fun segmental control. But there are tons.
How to use green light at home
To use them, sit in a room with no other light sources, including your phone or computer.
The light should be dim as a nightlight: bright enough to read by, but not much more.
Sit three to six feet away. Don’t look directly at the light, but keep it in your field of view.
Read a book, listen to music, do some exercise, or maybe be weird and just think. But keep your eyes open.
One to two hours per day. A lot, I know.
The effect is cumulative, so it might take a while to build up.
It doesn’t work for everyone, but this observational study, industry funded, found that it helps around 60% of people.
If you try it, please report back.
Additional Notes
Replying to @Lily. The caption says the research is still in its early phases, but that this is a low-cost intervention that is easy to try at home.
The creator asks viewers who try it to report back, and says the guide will be an evolving document after more devices are tested.
