Carpal tunnel syndrome (CTS) is a common condition caused by pressure on the median nerve in the wrist, often leading to pain, tingling, and numbness in the hand. Red light therapy (also known as low-level laser/light therapy) has gained attention as a non-invasive treatment option — but does it really help?
How Red Light Therapy Works for Carpal Tunnel
Red light wavelengths (630–850 nm) penetrate deep into soft tissue and trigger key biological responses:
-
Reduces inflammation around the irritated median nerve
-
Improves microcirculation, supplying oxygen and nutrients
-
Speeds up nerve repair through increased ATP production
-
Decreases pain signals by modulating nerve activity
This combination makes red light therapy particularly effective for nerve-related conditions like CTS.
Clinical Evidence
Research shows that red light therapy:
-
Improves nerve conduction velocity
-
Reduces wrist pain and numbness
-
Supports faster recovery when combined with wrist splints
-
Offers a non-invasive option without drug dependence
Best Devices for Results
Professional systems like Merican red light therapy panels deliver high irradiance and targeted wavelengths that reach deep into the wrist and forearm — allowing shorter treatment times and stronger therapeutic effects.
Conclusion
Red light therapy is a safe and promising solution for managing carpal tunnel symptoms. Its ability to reduce inflammation and support nerve repair makes it a valuable addition to your recovery routine.
