Can red light therapy help with chronic pain?
2025-06-05
What Is Red Light Therapy?
RLT uses low-level red or near-infrared light to penetrate the skin. It’s thought to stimulate cellular processes, particularly in the mitochondria, which may help reduce inflammation, promote healing, and alleviate pain. It’s often explored for conditions like arthritis, muscle soreness, joint pain, and even nerve-related discomfort.
Does It Help with Chronic Pain?
The evidence is promising but not definitive:
-
Some Positive Findings: Research suggests RLT may reduce pain in certain cases. For example:
-
Studies have shown benefits for osteoarthritis, reducing pain and improving joint function.
-
Research on chronic low back pain indicates it may lessen discomfort and enhance mobility.
-
Smaller studies suggest potential relief for fibromyalgia and neuropathic pain.
-
-
Mixed Results: Not all studies agree—some show little to no effect. Differences in light wavelengths, treatment duration, and individual responses contribute to inconsistent findings.
-
More Research Needed: Experts note that while RLT shows potential, larger, high-quality studies are necessary to confirm its effectiveness and establish standard protocols.
Is It Safe?
-
Generally Safe: RLT is non-invasive and has minimal side effects, like mild skin irritation or eye strain if not used properly. It doesn’t use UV light, so there’s no risk of skin damage.
-
Not a Cure-All: Results vary, and it may not work for everyone, depending on the type and severity of pain or individual factors like skin type and health.
Should You Try It?
RLT might be worth considering as a complementary approach, but it’s not a replacement for traditional medical treatments. Here’s how to approach it:
-
Talk to Your Doctor: Consult a healthcare professional to see if RLT suits your specific condition and to ensure it’s safe for you.
-
Set Realistic Expectations: Some people find relief, but others don’t. It’s not a guaranteed fix.
-
Use Quality Equipment: If trying it at home, choose FDA-cleared or clinically tested devices and follow instructions carefully.
Bottom Line
Red light therapy may help with chronic pain, especially for inflammation-related or musculoskeletal issues, based on some studies. However, the evidence isn’t conclusive yet, and more research is needed. For the best results, use it alongside evidence-based treatments and discuss it with your doctor before starting.
