It usually starts subtly. A bit of tingling in your thumb and first two fingers after a long day at the keyboard. You shake your hand, it goes away, you forget about it. Then it starts waking you up at night — that pins-and-needles feeling that no amount of shaking seems to shift. If that sounds familiar, your median nerve is trying to tell you something, and it’s worth listening before it starts shouting.

Carpal tunnel syndrome is one of the most common nerve conditions in the UK, and a lot of it is preventable — or at least manageable — with changes to how you work, move and rest. This isn’t about expensive gadgets or miracle cures. It’s about ergonomics, habits and paying attention to early warning signs.

What Carpal Tunnel Syndrome Actually Is

The carpal tunnel is a narrow passageway in your wrist, formed by bones and a tough band of tissue called the transverse carpal ligament. The median nerve and several tendons pass through it. When the tissues in or around the tunnel swell — from repetitive strain, fluid retention, or other causes — they squeeze the median nerve. That compression causes the tingling, numbness, pain and eventual weakness in the hand.

It’s more common in women, in people over 40, and in anyone whose work involves repetitive hand movements: typists, production line workers, musicians, carpenters, keen knitters. Pregnancy can trigger it too (usually temporary). And if you spend eight hours a day at a keyboard with your wrists bent at odd angles, you’re in the at-risk group whether you feel symptoms yet or not.

Wrist lumps can cause similar symptoms for different reasons — our guide on getting rid of a ganglion cyst covers one common culprit.

Set Up Your Workspace Properly

This is the single highest-impact thing most people can do, and most of us get it wrong.

Keyboard and mouse position

Your keyboard should be at a height where your forearms are roughly parallel to the floor and your wrists are straight — not bent up, down or sideways. If you’re reaching up to a keyboard on a too-high desk, or your wrists are cocked back, you’re compressing the tunnel all day. A keyboard tray or an adjustable chair (feet flat on the floor, by the way) fixes this for most people.

Keep the mouse close to the keyboard so you’re not reaching. If you use a mouse for hours, consider an ergonomic vertical mouse — it keeps your forearm in a neutral handshake position rather than twisted flat. They’re about £20–40 and take a few days to get used to, but many people with early symptoms swear by them.

Wrist rests: helpful or harmful?

Here’s a nuance people miss: wrist rests are for resting, not for typing. Planting your wrists on a rest while you type puts direct pressure on the carpal tunnel — the exact opposite of what you want. Use the rest during pauses, and keep your wrists floating while you actually type. Same goes for the edge of the desk or laptop: don’t lean your wrists on hard edges.

Laptop users, pay attention

Laptops are ergonomically terrible — the screen and keyboard are attached, so you can’t have both at the right height. If you work on a laptop for hours daily, a separate keyboard and mouse plus a laptop stand (so the screen is at eye level) is one of the best investments you can make. Your neck will thank you too.

Build Better Habits Through the Day

Take proper breaks

The research on this is consistent: frequent short breaks beat occasional long ones. Aim for a minute or two away from the keyboard every 20–30 minutes — stand up, shake out your hands, roll your shoulders. Set a timer if you won’t remember on your own. It feels disruptive for the first week and then becomes automatic.

Vary your tasks

If your job allows it, alternate keyboard-heavy work with phone calls, reading, meetings — anything that gives your hands a rest. Repetition is the enemy; variety is protective.

Watch your grip

Many of us grip the mouse too tightly, hammer the keys, or clutch tools with a death grip. Consciously relax your hands periodically. If you notice your shoulders are up around your ears, drop them. Tension travels down the arm and into the wrist.

Exercises and Stretches That Help

There’s decent evidence that nerve-gliding and tendon-gliding exercises help keep things moving freely through the tunnel. Try these a few times a day:

• Prayer stretch: Press your palms together in front of your chest, fingers pointing up, and slowly lower your hands toward your waist until you feel a stretch in the wrists. Hold 15–20 seconds. Then reverse it: backs of hands together, fingers pointing down.
• Wrist flexor stretch: Extend one arm straight out, palm up. With the other hand, gently press the fingers down and back. Hold 15–20 seconds per side.
• Nerve glides: Make a fist, then open to a straight hand, then bend the wrist back with fingers extended, then spread the fingers wide. Move slowly through the sequence five times. It looks odd; it works.
• Shake it out: Literally shake your hands loosely for 10–15 seconds, like you’re air-drying them. Simple, surprisingly effective for relieving that tingly build-up.

These aren’t a cure for established carpal tunnel syndrome, but they’re genuinely useful for prevention and for easing mild symptoms. The NHS page on carpal tunnel syndrome includes self-care guidance along these lines.

Night-Time Measures

Symptoms are often worst at night because we sleep with our wrists bent — curled under the pillow is the classic position. A night wrist splint holds the wrist straight while you sleep and can make a dramatic difference to night-time tingling and numbness. They’re available from pharmacies like Boots and Superdrug for around £10–20, no prescription needed.

It takes a few nights to get used to sleeping in one, but most people adapt quickly. If night symptoms are your main problem, this alone is worth trying before anything else.

Lifestyle Factors Worth Knowing

Some risk factors you can’t change (being female, getting older — the usual unfairnesses), but a few you can influence:

• Maintain a healthy weight. Higher BMI is associated with increased carpal tunnel risk, partly because of extra tissue pressure in the tunnel.
• Manage conditions like diabetes and thyroid problems. Both increase risk; keeping them well controlled helps.
• Stay generally active. Good circulation and upper-body strength support healthy nerves and tendons. You don’t need to take up boxing — regular walking and some basic strength work does it.
• Don’t ignore early symptoms. Tingling that comes and goes is your early warning system. The people who end up needing surgery are often the ones who ignored the tingling for a year.

When to See a GP

Self-help goes a long way, but see your GP if:

• Symptoms persist for more than a couple of weeks despite changes
• Numbness is constant rather than intermittent
• You’re dropping things or notice weakness in your grip or thumb
• Symptoms are significantly affecting sleep or work
• You notice wasting (thinning) of the muscles at the base of the thumb — this needs prompt attention

Treatment options range from steroid injections to a small surgical procedure that releases the ligament — it’s usually done as day surgery with a good success rate. But the goal of everything above is to never need to find that out.

Frequently Asked Questions

Can carpal tunnel go away on its own?

Mild cases, especially those related to pregnancy, often improve on their own or with conservative measures like splinting and ergonomic changes. Established cases with persistent numbness or weakness are less likely to resolve without treatment, so don’t wait indefinitely hoping it’ll pass.

Are ergonomic keyboards worth it?

They can help, particularly split or tented designs that keep wrists in a more neutral position. But no keyboard fixes bad posture or marathon typing sessions without breaks. Think of ergonomic kit as supporting good habits, not replacing them.

Does cracking your knuckles cause carpal tunnel?

No — that’s a myth. Knuckle cracking hasn’t been shown to cause carpal tunnel syndrome or arthritis. Annoying to everyone within earshot, yes. Harmful, no.

I’m pregnant and my hands tingle at night — is it carpal tunnel?

Very possibly — fluid retention in pregnancy commonly compresses the median nerve. The good news is it usually resolves after delivery. Night splints and the exercises above are safe to try, but mention it to your midwife or GP.

The Bottom Line

Avoiding carpal tunnel mostly comes down to respecting your wrists: set up your workspace so they’re straight, take real breaks, do a few stretches, wear a night splint if symptoms start, and don’t ignore early tingling. None of this is complicated or expensive — it’s just the unglamorous business of looking after the body parts you use all day, every day. Your hands have a lot of years of typing ahead of them. Treat them accordingly.
