Numb, tingling hands at night: what helps and when to see a doctor

According to the NHS, brief pins and needles happens when the blood supply to the nerves is cut off for a moment — typically when you sit or lie on part of your body. It only lasts a few minutes and stops once the pressure is off. (NHS — Pins and needles)

This article is practical guidance; it is not a diagnosis or treatment.

When your arm “falls asleep” under you

1. Take the pressure off: change position and let the arm rest freely; brief pins and needles should fade within a few minutes. (NHS — Pins and needles)
2. Notice repeats: if the tingling is constant or keeps coming back, that is a reason to see a doctor, not just to roll over again. (NHS — Pins and needles)

Carpal tunnel: a common night-time culprit

• Carpal tunnel syndrome is pressure on a nerve in the wrist. It causes tingling, numbness and pain in the hand and fingers, sometimes a weak thumb or difficulty gripping. (NHS — Carpal tunnel syndrome)
• Symptoms often start slowly and come and go — and, according to the NHS, they are usually worse at night. (NHS — Carpal tunnel syndrome)
• Risk is higher, among other things, in pregnancy, if you are overweight, if you often bend your wrist or grip hard, with arthritis or diabetes, and if close relatives have it. (NHS — Carpal tunnel syndrome)

What you can try yourself

1. A wrist splint at night: it keeps the wrist straight and relieves pressure on the nerve; you wear it at night while you sleep. It may take up to 6 weeks to feel better; splints are also sold in pharmacies. (NHS — Carpal tunnel syndrome)
2. Less strain during the day: cut down on frequent wrist bending and hard gripping — such as using vibrating tools or playing an instrument. (NHS — Carpal tunnel syndrome)
3. Painkillers only short-term: they may ease pain for a while, but the NHS says there is little evidence they treat the cause — don’t rely on them. (NHS — Carpal tunnel syndrome)
4. Hand exercises: according to the NHS there is only a small amount of evidence that they help. (NHS — Carpal tunnel syndrome)
5. Patience in pregnancy: carpal tunnel syndrome sometimes gets better by itself within a few months, particularly when it is linked to pregnancy. (NHS — Carpal tunnel syndrome)

When to see a doctor

• See a GP if carpal tunnel symptoms get worse, do not go away or home treatment is not working. Options include a nerve test, a steroid injection and — if nothing else works — surgery, which usually cures the condition. (NHS — Carpal tunnel syndrome)
• See a doctor too if the tingling is constant or keeps coming back — there can be several causes, such as diabetes or nerve problems. Don’t self-diagnose. (NHS — Pins and needles)
• Numbness and tingling in the hands or feet, burning or stabbing pain, or balance problems are among the symptoms of peripheral nerve damage; the NHS advises seeing a GP with early symptoms. In the UK, the most common cause is diabetes. (NHS — Peripheral neuropathy)
• Call your local emergency number (such as 999 in the UK or 112 in the EU) if you suddenly get weakness or numbness in one arm or down one side of the body, a drooping face or speech problems — even if the symptoms then stop. It may be a stroke. (NHS — Stroke symptoms)
• If tingling wakes you so often that you have slept badly for months and it affects your day, talk to a doctor about your sleep; adults usually need about 7 to 9 hours. (NHS — Insomnia)

Takeaways

1. Brief tingling after lying on your arm is common and passes within minutes.
2. Tingling fingers that wake you repeatedly may be linked to carpal tunnel.
3. A night-time splint keeps the wrist straight — improvement can take weeks.
4. Constant or recurring tingling needs a doctor.
5. Sudden weakness or numbness on one side of the body means calling an ambulance.

A hand that tingles at night can wreck your sleep — but the right position, a night splint and seeing a doctor in time often bring calm back to both your hands and your nights.
