If you are regularly woken by pins and needles in your hand, or you shake your fingers out first thing in the morning to get the feeling back, you are not alone. Night-time numbness is one of the most common reasons people look for a wrist splint.
This guide explains why symptoms tend to be worse at night, what a night splint does and how to use one properly.
Why hands go numb at night
During sleep most of us curl the wrists inwards or tuck a hand under the pillow. Holding the wrist bent for long periods narrows the space at the front of the wrist through which a major nerve and several tendons pass. If that space is already a little crowded, perhaps because of swelling, repetitive use or pregnancy, the nerve can be compressed and the fingers go numb or tingly. Straightening the wrist usually relieves it, which is why shaking the hand out helps.
What a night wrist splint does
A night splint is a fabric support with a firm stay running along the palm side of the wrist. The stay holds the wrist in a neutral, straight position so it cannot curl while you sleep. By keeping the wrist straight, pressure in the carpal tunnel area is reduced and many people find their night-time symptoms settle.
Night splints are a widely recommended first step for mild to moderate carpal tunnel type symptoms, often alongside activity changes and exercises.
Choosing a night splint
- Neutral angle: look for a splint that holds the wrist straight, not bent back. Some sports supports hold the wrist in extension, which is not what you want for sleep.
- Removable stay: useful for washing and for adjusting the shape slightly.
- Soft lining and smooth edges: you will be wearing it for seven or eight hours at a time.
- Open thumb and fingers: so the hand stays free and does not overheat.
- Left or right: most night splints are side-specific. Check before ordering.
How to wear it
- Put the splint on just before bed, with the stay along the palm side of the wrist.
- Fasten the straps so it feels secure but not tight. You should not feel throbbing or see marks after a few minutes.
- Check that your fingers can move freely and are not pale or cold.
- Remove it in the morning and move the wrist gently through its full range.
Give it a couple of weeks of consistent use before judging whether it is helping.
Daytime habits that help
- Avoid holding the wrist bent for long periods, for example while holding a phone or steering wheel.
- Take regular breaks from repetitive hand tasks.
- Keep the hand moving with gentle finger and wrist stretches.
When to get advice
See a healthcare professional if numbness is constant rather than intermittent, if you notice weakness or wasting of the muscle at the base of the thumb, if you drop things, or if symptoms have not improved after a few weeks of splinting. Numbness during pregnancy often settles after birth but should still be mentioned to your midwife or GP.
Frequently asked questions
Can I wear a night splint during the day?
You can for rest periods, but it limits movement, so it is not ideal for typing or active tasks. A lighter wrist sleeve or wrap is usually better in the day.
Should I wear it on both hands?
Only if both have symptoms. Some people alternate if symptoms switch sides.
Will a night splint cure the problem?
It relieves symptoms and gives the nerve a rest, which is often enough for mild cases. It does not treat an underlying cause, so get assessed if things do not improve.
