The stiffness that greets you before you've even sat up
You know the feeling before your eyes are properly open. You go to roll over and your neck won't quite turn. Or you sit up and your lower back takes a few seconds to agree to it. By the time you've had a cup of tea it's usually easing off, but it's an odd way to start the day.
Most people assume this is just age, or a bad mattress, or sleeping funny. Sometimes it's one of those. But the position you settle into for hours at a time, and how much you move while you're there, plays a real part too.
Why lying still for hours is different from sitting still for hours
When you're awake, you shift your weight constantly without thinking about it. You lean, stretch, cross and uncross your legs. Asleep, you do move, but far less deliberately, and for long stretches you can end up holding one position for much longer than you would ever choose to sitting in a chair.
Joints and muscles generally cope fine with sustained positions for a while. The trouble tends to come when a position puts one part of you under more strain than the rest, night after night, without much variation. A neck bent sideways against a pillow for seven hours, or a lower back twisted against a mattress, can leave you feeling it in the morning even if it caused no bother at all the evening before.
Front, side and back: what tends to happen with each
Sleeping on your front usually means your head is turned to one side for hours, which asks a lot of the muscles on one side of your neck. It also tends to flatten the natural curve of your lower back against the mattress, which some people notice more than others.
Sleeping on your side is common and often comfortable, but if your neck is angled up or down rather than roughly level, or if your top leg is dragging your hip and spine round, you can wake up with stiffness through the neck, shoulder or lower back on one side in particular.
Sleeping on your back generally keeps the spine in a more neutral line, which is why it's often mentioned as easier on the neck and lower back. It's not the right position for everyone, though, and plenty of people who sleep well and wake up fine do so on their side or front. There's no single correct way to lie.
Pillows, mattresses, and small things that actually make a difference
A pillow's job is to keep your neck roughly in line with the rest of your spine, whatever position you sleep in. Too high or too thick, and your neck is bent up all night. Too flat, and it drops back. If you sleep on your side, a slightly firmer or thicker pillow that fills the gap between your ear and shoulder is often more comfortable than one that works for someone sleeping on their back.
A mattress that's sagged in the middle, or one that's simply worn out, can let your hips or shoulders sink lower than the rest of you, which pulls the spine out of a neutral line for the whole night. You don't need to spend a fortune working this out. If you wake up with an outline of the mattress's dips pressed into you, or if it's several years old and visibly sagging, that's worth paying attention to.
Small adjustments help too. A pillow between the knees if you sleep on your side can stop the top leg twisting your hips. A thin pillow under the stomach if you sleep on your front can ease some of the strain on your lower back. None of these are fixes for everyone, but they're worth trying.
When it's more than just a stiff morning
Stiffness that eases within half an hour or so of getting up and moving about is a very ordinary thing, and most people experience it from time to time. It becomes worth a proper look when it doesn't ease, when it's getting worse over weeks, when it's accompanied by pain running down an arm or leg, numbness, or pins and needles, or when it's disturbing your sleep itself rather than just greeting you at the end of it.
Any of those are worth mentioning to a doctor, particularly numbness, weakness, or pain that spreads. For stiffness that's more of a persistent nuisance than an alarm bell, an osteopath can have a look at how your neck, back and joints are moving and whether anything there seems to be contributing.
What to do next
If mornings routinely start with stiffness that takes a while to shift, it's worth looking at your pillow, your mattress, and the position you tend to wake up in. If it isn't easing or is joined by numbness, weakness or spreading pain, see a doctor; for ongoing stiffness without those signs, our osteopaths can take a look and can be reached on 0747 124 8330.
