How Can a Wrist Brace Help?
Most people bend their wrists when they sleep. That puts pressure on the median nerve. A brace can help because it keeps your wrist in a straight, neutral position. A 2012 study found that using a wrist brace at night did more to relieve carpal tunnel symptoms than using no treatment at all.
You may also find it helpful to wear a brace during the day, especially during activities that trigger flare-ups. Repeated motions or extra strain on your wrist can make your symptoms worse. If your job allows for it, try wearing a brace at work.
