Red light therapy may help relieve diabetic neuropathy symptoms like pain, tingling, and numbness by improving circulation and reducing nerve inflammation.
Red Light Therapy for Diabetic Neuropathy: Does It Work?
Red light therapy (RLT) has shown promise as a complementary approach for managing diabetic neuropathy symptoms such as tingling, burning pain, numbness, and sensitivity—particularly in the feet and legs.
📚 Several small human trials and animal studies have found that red (around 660–670 nm) and near-infrared (810–850 nm) light can:
🩸 Increase microcirculation to nerve tissue
🔬 Reduce oxidative stress and inflammatory markers
🧠 Potentially stimulate nerve repair and regeneration
One study found significant reductions in pain and improved sensory function in patients after just 12 sessions of near-infrared therapy applied to the lower limbs. The proposed mechanism is enhanced mitochondrial function and local blood flow, which supports nerve healing.
✅ What people report: Many users experience a decrease in discomfort and better quality of life with consistent use (e.g., 3–5x per week).
⚠️ However, results vary based on the severity of the condition, treatment consistency, and wavelength used. RLT is not a cure for neuropathy and should be used alongside medical care—not in place of it. Speak with your healthcare provider before starting if you have severe neuropathy, ulcers, or circulatory complications.
