Red Light Therapy for Muscle Recovery
Written by RedLightOS Research Team · Photobiomodulation Research, Clinical Protocol Development
The Bottom Line
Red and near-infrared light therapy at 660-850nm reduces exercise-induced muscle damage markers (creatine kinase, LDH) and self-reported soreness when applied pre- or post-exercise. Dose: 3-20 J/cm², 10-20 minutes, within 2 hours of exercise. Evidence grade: B (moderate — consistent findings across multiple studies).
How Does Red Light Therapy Help Muscle Recovery?
Red and NIR light increase mitochondrial ATP production in muscle tissue, reduce oxidative stress markers (CK, LDH), decrease inflammatory cytokines, and accelerate satellite cell activation for repair.
Recommended wavelengths: 660nm, 810nm, 850nm

What We Don't Know Yet
Evidence is moderate — based on limited randomized controlled trials. Larger, more rigorous studies are needed. Optimal dosing parameters are not yet standardized across research groups.
