How Many Hours Daily to Wear a Wrist Brace for Carpal Tunnel?
How many hours a day should I wear a wrist brace for carpal tunnel?
The Quick Answer
**Wear rigid splints nightly for 8 hours during sleep**—this is non-negotiable for effective treatment. Daytime wear should be limited to **2–4 hours during aggravating activities only** (typing, driving). Never wear continuously beyond 4 hours daytime to prevent tendon stiffness and muscle weakness. Total daily wear should not exceed 10–12 hours. Consistent 8-week nightly protocol is required before expecting significant symptom improvement.
Why We Ask This
Patients either wear braces 24/7 believing 'more is better' (causing secondary stiffness) or wear them sporadically during daytime only while neglecting critical nighttime protection—both approaches failing because nocturnal flexion causes the most sustained, damaging nerve compression.
The Practical Science
Carpal tunnel pressure spikes to 110mmHg during sustained sleep flexion versus 30mmHg neutral—lasting hours versus minutes during daytime activities. Nighttime protection addresses the primary biomechanical insult; daytime use is adjunctive for symptom management during provocative tasks only.
In Clinical Practice
A graphic designer wears a rigid splint every night for 8 weeks (non-negotiable) plus a flexible support during 3-hour computer sessions—but removes it for meals, phone use, and exercises—achieving 75% symptom reduction versus minimal improvement with daytime-only wear that failed to address nocturnal compression.
