Here is the short answer. Numbness with an obvious cause, like sleeping on your arm or leaning on your elbow through a long meeting, is normal and clears within a few minutes. Numbness or tingling that keeps coming back, wakes you at night, or shows up during ordinary activities is worth paying attention to. It usually means a nerve is being compressed or irritated somewhere between your neck and your fingertips, and there is often a simple reason for it: something has stopped moving the way it should.

Your nerves are built to move

Here is the part most people have never been told. The nerves that run from your neck down into your hand are not fixed cables. They are designed to glide and slide as you move. When researchers tracked the median nerve on ultrasound, they found it slides several millimetres every time you bend your wrist, elbow or neck (Coppieters et al., Clinical Biomechanics, 2003). Movement is how a nerve stays healthy. It gets its blood supply, its space and its freedom to slide from you moving through the day.

Now think about what winter does to that. We all move less. We sit longer. We spend more time in one position: at the laptop, curled on the couch, phone in hand, elbow bent under the pillow all night. A nerve that would normally glide freely spends hours held still under a bit of load. That is when a nerve that was coping quietly can start to complain.

Why “you move less” is often the real story

This is the pattern I see most in the clinic through the colder months. Cold weather does not create nerve problems out of nothing. What it tends to do is take away the movement that was keeping a borderline nerve comfortable. Less walking, less incidental activity, more sitting still. The nerve has not been injured. It has simply lost the movement it relied on.

There is good news in that. If the problem is that a nerve stopped moving, the answer is usually not to rest it completely. It is to get it moving again in a gentle, controlled way, take the load off the spot where it is being compressed, and restore motion in the joints and muscles around it.

Where hands actually go numb

Your hand is the end of a long line that starts in your neck. Pressure anywhere along that line can cause numbness, and which fingers are affected tells us a lot about where the problem sits.

• At the wrist (carpal tunnel): tingling in the thumb, index and middle fingers, classically worse at night, often eased by shaking the hand out. Confirmed carpal tunnel affects roughly 3 per cent of adults, though closer to one in seven report symptoms at some point (Atroshi et al., JAMA, 1999).
• At the neck (cervical radiculopathy): a pinched nerve where it exits the spine, with numbness running in a strip down the arm into specific fingers, often alongside neck stiffness. It affects around 83 people per 100,000 each year and peaks in the 50s (Radhakrishnan et al., Brain, 1994). Reassuringly, in that same study about 90 per cent of people were symptom-free or only mildly affected at follow-up. Managed well, it usually settles.
• At the elbow (ulnar nerve): tingling in the ring and little fingers, stirred up by leaning on the elbow, holding a phone to the ear, or sleeping with the elbow bent tight.

A few simple self-checks

• Do I wake at night and shake my hands to get the feeling back? That is a common carpal tunnel pattern.
• Does the same patch of my hand go numb during specific activities, like cycling, driving or scrolling? A repeating pattern usually means a specific nerve is involved.
• Am I dropping things, or does my grip feel weaker? Weakness can mean the nerve has been under pressure for a while, so it is worth having it looked at sooner rather than later.
• Is it both hands at once, or numbness along with balance or walking changes? That combination is best taken to your GP promptly.

What I do about it

The first step is a proper assessment to find where along the line the nerve is being affected. I check the neck, shoulder, elbow and wrist, test how the nerve slides and how it tolerates load, and map exactly which fingers are involved. Treating the wrist when the real restriction is in the neck does not get results.

From there the plan is movement based. Restore motion in the stiff segments, take load off the compression point, and give you specific exercises and simple workstation changes so the nerve keeps gliding the way it is meant to between visits. I will always be upfront about what responds well to this and what does not. Established carpal tunnel, for example, sometimes needs more than hands-on care, and if your symptoms do not behave the way a straightforward compression should, I will refer you for nerve conduction studies or back to your GP. Some hand numbness has medical causes worth ruling out, including diabetes and thyroid conditions.

The bottom line

Occasional, explainable numbness is nothing to worry about. Numbness with a pattern is your body letting you know that something has stopped moving well, and it is much easier to sort out early than late. If your hand has been going numb on and off for weeks or months, it is worth finding out why. The fix is usually not less movement. It is the right movement.

Book an assessment and we will work out exactly where it is coming from.
