If you work out hard, you know the pain of delayed-onset muscle soreness (DOMS) — that stiff, sore feeling 24–72 hours after intense training. Red light therapy is one of the few interventions with solid evidence for reducing DOMS and accelerating muscle recovery. Here's how athletes use it.
What the Research Says
Red light therapy has solid evidence for muscle recovery:
- Multiple RCTs show reduced DOMS (delayed-onset muscle soreness) when RLT is applied before or after intense exercise.
- Studies show reduced CK (creatine kinase) markers — a blood marker of muscle damage — in athletes using RLT.
- Performance improvements: some studies show increased repetition count and reduced fatigue in subsequent training sessions.
- The mechanism: NIR light reduces muscle inflammation and stimulates mitochondrial function in muscle cells.
The Recovery Protocol
- Position the panel 6–12 inches from the trained muscle group. Treat each major muscle group separately for full coverage.
- Treat for 3–5 minutes per muscle group immediately after training. Post-workout RLT reduces inflammation and speeds recovery.
- Alternatively, treat for 3–5 minutes per muscle group before training. Pre-workout RLT may enhance performance and reduce muscle damage.
- Repeat daily during intense training blocks. For competition prep, treat 2x daily (morning and post-workout).
- Combine with proper sleep and nutrition. RLT enhances recovery but doesn't replace sleep, protein, and hydration.

Pre-Workout vs. Post-Workout
Pre-Workout RLT (3–5 minutes before training)
- May enhance muscle performance and power output
- Reduces muscle damage from the workout
- Improves mitochondrial function during exercise
Post-Workout RLT (3–5 minutes after training)
- Reduces DOMS (delayed-onset muscle soreness)
- Speeds recovery between training sessions
- Reduces muscle inflammation markers
Both (Pre + Post)
For serious athletes, treating both before and after training delivers the best results. Most studies showing performance improvements used this protocol.
