Night Wrist Splinting
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Wear a rigid or semi-rigid splint that holds the wrist in a neutral (straight) position while you sleep, every night for at least 4-6 weeks. Choose one labeled for carpal tunnel with a metal or plastic stay - it should keep the wrist from bending, not just compress it. Daytime wear during aggravating tasks (typing, driving) can add benefit, but night wear is the core intervention.
How it works
Pressure inside the carpal tunnel is lowest when the wrist is straight and rises sharply when it flexes or extends - positions the hand naturally curls into during sleep. Holding the wrist neutral overnight reduces sustained pressure on the median nerve, easing nighttime tingling and allowing irritated nerve tissue to recover.
Where to buy
Pharmacies, Amazon, or medical supply stores - Mueller Fitted Wrist Brace, Futuro Night Wrist Sleep Support, and Wellgate PerfectFit are common options.
Typical cost: $15-$30 one-time
Safety notes
A splint that is too tight can worsen numbness - loosen it if tingling increases. Splinting treats mild to moderate cases; if you have constant numbness or thumb muscle weakness, see a doctor rather than relying on a splint. Do not strap the wrist into a bent position - neutral is the goal.
