Can red light therapy help with fibromyalgia or chronic fatigue?
2025-06-07
Red light therapy (RLT) is a treatment that uses low-level wavelengths of red light to stimulate cellular function, often applied for pain relief, wound healing, and skin conditions. There’s growing interest in whether it might help with conditions like fibromyalgia and chronic fatigue. Here’s what we know so far:
Fibromyalgia
Fibromyalgia involves widespread musculoskeletal pain, fatigue, and other symptoms like sleep issues and mood disturbances. RLT shows some potential benefits:
-
Pain Reduction: Small studies suggest RLT may reduce pain and tenderness by boosting cellular energy production (via mitochondria) and reducing inflammation, which could ease the chronic pain common in fibromyalgia.
-
Sleep and Mood: There’s limited evidence that RLT might promote relaxation and improve sleep quality, which could indirectly help with fibromyalgia symptoms, though more research is needed.
-
Current Evidence: While some clinical trials report modest improvements in pain and quality of life, these studies are small, and larger, more rigorous research is still required to confirm the effectiveness.
Chronic Fatigue
Chronic fatigue syndrome (CFS) is marked by extreme, persistent fatigue that doesn’t improve with rest. The evidence for RLT here is less clear:
-
Energy Boost: RLT is thought to enhance mitochondrial function, potentially increasing cellular energy. This could theoretically reduce fatigue, but there’s little direct research on RLT for CFS specifically.
-
Symptom Relief: Anecdotal reports suggest some CFS patients feel less fatigued after RLT, and it might help with related issues like muscle pain or poor sleep. However, these benefits aren’t well-supported by scientific studies yet.
-
Research Gap: Without robust clinical trials, it’s hard to say if RLT reliably improves energy levels in CFS.
Key Considerations
-
Safety: RLT is generally safe, with minimal side effects (like temporary skin redness), but it’s not a replacement for established treatments. Consult a healthcare provider before starting it.
-
Variability: Benefits can differ from person to person—some may notice relief, while others may not.
-
Practicality: RLT devices or professional sessions can be costly and may not be covered by insurance, so consider the investment versus the uncertain outcomes.
Bottom Line
Red light therapy might offer some relief for fibromyalgia symptoms, particularly pain, and could have potential for fatigue in chronic fatigue syndrome. However, the evidence is still emerging, and it’s not a proven cure for either condition. If you’re thinking about trying it, view it as a complementary option alongside conventional treatments, and discuss it with your doctor to see if it’s worth a shot for you. More research is needed to fully understand its effectiveness.
