Night splinting is commonly recommended for carpal tunnel syndrome because it helps stop the wrist bending while you sleep.
NHS guidance advises wearing a wrist splint at night and notes that it may need to be used for up to around six weeks before symptoms start to improve.
Why are carpal tunnel symptoms worse at night?
Many people naturally sleep with the wrist bent. This can increase pressure around the median nerve and contribute to tingling, numbness or waking with an uncomfortable hand.
What does a night splint do?
It keeps the wrist closer to a neutral position so it is less likely to remain flexed or extended for long periods during sleep.
Does the brace need to be very tight?
No. It should be secure enough to maintain its position, but excessive strap tension can create unnecessary pressure.
How long should you try night splinting?
NHS advice says a splint may need to be worn at night for up to six weeks before it starts to feel better.
Should you also wear it during the day?
Not necessarily. Some people may use a splint for specific aggravating tasks, but all-day immobilisation is not automatically required.
Can you reduce use once symptoms improve?
NHS England decision-support information suggests that once symptoms improve, splint use can be gradually reduced.
Night splinting should make the wrist more comfortable, not less. Check the fit if the brace increases numbness, tingling, pressure or pain.
What if night splinting does not help?
See a healthcare professional if symptoms are worsening, are not going away or self-management is not working. Other treatment options may be considered depending on severity.
