Ever wondered if shining a colored light on your body could actually reduce pain? You're not alone. Red vs. green light therapy for pain has become a hot topic for anyone battling discomfort—from stiff joints to pounding migraines.
But which one works better? And how do you even begin to choose?
Let’s untangle that question and shed some... well, light... on the subject.
Red vs. Green Light Therapy for Pain
Red and green lights might look similar in a gadget, but they couldn’t act more differently once they hit your skin. Red light dives deep. A green light hangs around the surface. So, depending on what’s hurting—and where—it matters which one you pick.
Red light is known for its deeper tissue penetration. That means it targets sore muscles, tendons, and even joint inflammation. It’s like having a warm, invisible hand massage you from the inside.
Green light? It’s a gentler touch. Perfect for surface-level pain, especially when triggered by nerve signals like migraines. Some studies even show it’s useful in calming the nervous system.
So yeah, the color counts.
Understanding Light Therapy for Pain Relief
Ever felt better after a little sunlight? Light therapy works on a similar principle. But instead of full-spectrum sunlight, it uses targeted wavelengths to tell your cells what to do.
- Light = energy. When certain light waves hit your skin, your cells absorb them like little solar panels.
-
Result? More ATP (cellular energy), better blood flow, and less inflammation.
Think of it like rebooting your body’s software—quick, painless, and non-invasive.
Different wavelengths = different effects. That’s where the red vs. green battle comes in.
Breaking Down Red Light Therapy
Here’s where things get a little sci-fi—in a good way.
Red light therapy uses wavelengths between 630–660nm, which allows it to sink into your skin and reach your muscles, tendons, and bones. That’s why it’s often the go-to for:
- Arthritis
- Tendonitis
- Post-surgery healing
- Muscle recovery
Why does red light work for deep pain?
Your mitochondria love red light. And when they get enough of it, they ramp up ATP production. More energy means faster repair. Less inflammation. And best of all? Less pain.
It’s like charging a dying phone battery—except it's your joints we’re powering up.
Exploring Green Light Therapy
Green light has a wavelength of around 520–560nm. That shorter range means it doesn't go deep, but that’s not a downside.
It’s a strength.
What is green light therapy good for?
- Migraine and headache relief
- Fibromyalgia
- Superficial nerve pain
-
Eye strain and light sensitivity
Green light interacts with pain pathways closer to the skin and nerves. It tells your brain, “Hey, this area’s good. You can stop freaking out now.”

Why do these differences matter?
Because if you’re treating a sore knee, green light won’t cut it. And if you’re fighting a migraine, a red light might not help at all. Matching the treatment to your pain source is everything.
How to Choose Between Red and Green Light Therapy
Still on the fence? Here’s a quick cheat sheet.
Pick red light therapy if you:
- Suffer from deep muscle soreness
- Have joint inflammation or arthritis
- Are you recovering from an injury or surgery
Pick green light therapy if you:
- Get migraines more than twice a week
- Have fibromyalgia or nerve-based pain
-
Are sensitive to bright lights
Should you use both?
You can. Some people alternate depending on their symptoms. Just don’t use both at once—your body might not know which signal to respond to.
What about safety?
Both are safe for most people when used properly. Avoid overexposure, especially near your eyes, and always follow the manufacturer's directions.

FAQs
Is red or green light therapy better for back pain?

How often should I use red or green light therapy?
2–5 times per week is a good range for most people, depending on pain severity and type.
Are there any side effects of light therapy?
Mild redness or warmth is common, but it usually fades quickly. Avoid using it on tattoos or broken skin.
Can I use light therapy at home?
Absolutely. Many FDA-cleared devices are available for safe, home-based treatment.
How long does it take to see results?
Some people feel relief after just one session. For others, it might take 2–4 weeks of consistent use.
Conclusion
When comparing red vs. green light therapy for pain, it’s not about picking the "best" one—it’s about picking the right one.
Red light goes deep and helps your body heal itself from the inside out. Green light calms your nerves and eases surface-level pain. Choose based on your pain type, and you’re halfway to relief.
