Waking with tingling fingers or an aching hand can make it difficult to get a restful night. Carpal tunnel syndrome is one possible cause, and symptoms often become more noticeable at night. A suitable wrist splint may help by limiting wrist bending while you sleep.
Here we explain the purpose of a night splint, what to look for and when to ask for medical advice. Not all hand numbness is carpal tunnel syndrome, so recurring symptoms deserve a proper assessment.
Why can carpal tunnel feel worse at night?
Carpal tunnel syndrome involves pressure on the median nerve as it passes through the wrist. Symptoms can include tingling, numbness, pain and difficulty gripping. The NHS explains that symptoms are usually worse at night.
Wrist position matters. Keeping the wrist in a neutral position can reduce compression or irritation of the nerve. A night splint helps maintain that position when you are asleep and less aware of how your wrist is resting.
How can a wrist splint help?
A wrist splint uses a firm stay to restrict bending. For carpal tunnel, the aim is to support the wrist in a neutral position, rather than squeeze it tightly. Kent Community Health NHS Foundation Trust includes night splinting among conservative treatment options.
A soft sports wrist strap has a different construction and may not control wrist position in the same way. Check the product's intended use and follow any advice from your GP or hand therapist.
Choosing a splint for night-time use
Look at the fit and construction before choosing:
- Wrist support: a firm stay designed to limit wrist bending.
- Correct hand and size: check whether the splint is for the left or right hand and use that product's measuring guide.
- Adjustable fastenings: straps should let you secure the splint comfortably.
- Material: check the composition, particularly if you have allergies or sensitive skin.
Our bestselling product, the Actesso Breathable Wrist Splint, has sold millions of units through our website and Amazon since 2012. It has an under-wrist metal stay, adjustable straps and separate left- and right-hand versions. Measure your wrist and check the size chart before ordering. It contains latex, so it is not suitable for someone with a latex allergy.
Check the fit before bedtime
Try a new splint while awake first, following the supplied instructions. Check that the edges and straps are not rubbing and that it feels secure without excessive pressure.
Stop wearing it and seek advice if it causes skin soreness, a rash, greater discomfort or worsening symptoms. These checks are also highlighted in South Tees Hospitals' splint guidance. Tightening a splint further is not the answer to persistent tingling.
How quickly might you notice a difference?
Improvement is not necessarily immediate. The NHS says it may take up to six weeks before a night splint starts to help. Your clinician may recommend a different trial period depending on your symptoms. A splint does not help everyone or replace assessment when symptoms continue.
When should you seek medical advice?
Contact your GP if symptoms are worsening, are not going away or are not improving with home treatment. Mention persistent numbness, thumb weakness or difficulty holding everyday objects. Do not wait until the end of a splint trial if symptoms deteriorate.
