Sit for long enough and a joint stops behaving like a joint. It behaves more like something in storage. The cartilage that cushions your knees and hips relies on movement to stay lubricated — synovial fluid moves through the joint as you bend and straighten it, and when that stops happening for hours at a stretch, the joint stiffens. Stand up after a long stretch at a desk and the first few steps often feel wrong in a way that has nothing to do with age and everything to do with stillness.

Sitting for several hours a day does something specific to the joints: they stiffen. Not from damage, but from disuse. Cartilage in the knees, hips, and ankles gets its nutrients not from blood vessels — it has none — but from the compression and release of movement. When you sit still for a long stretch, that exchange slows down, and tissue that needs regular loading to stay healthy simply doesn’t get it. The stiffness that sets in after a long car journey or an afternoon of reading isn’t just discomfort. It’s the body’s way of signalling that it needs

Muscles change after the age of 60 in ways that aren’t always obvious at first. They recover more slowly. Tissue that was once pliable starts to feel like it’s pulled tighter overnight. A walk that left you feeling loose before might now leave your calves stiff for a day or two. None of this is unusual — it’s partly a shift in how fascia, the connective tissue surrounding muscle fibres, responds to loading and rest. But understanding what’s happening makes it easier to do something practical about it. This article is for information only and does not constitute medical

Some people move into their seventies with relatively little fuss — still walking purposefully, managing stairs without hesitation, carrying shopping without thinking twice about it. Others hit 65 feeling like their body has started a negotiation they did not agree to enter. The difference is rarely about exceptional genetics or unusual discipline. Research tracking older adults in England found that today’s over-65s show higher levels of physical and mental functioning than previous generations did at the same age — which suggests the gap between those who stay mobile and those who do not is at least partly about choices

Most people understand that exercise is good for joints. What gets less attention is what happens on the days in between — and why those days matter as much as the workout itself. After 60, muscle repair slows, connective tissue takes longer to recover, and the gap between doing too much and doing too little becomes narrower. How you spend your rest days has real consequences for how your joints feel the rest of the week. This article is for information only and does not constitute medical advice.

Most people who develop knee pain start looking at the knee. Most people with a stiff hip assume the problem is in the hip. It often isn’t — or at least, not entirely. The ankle is where many of these problems begin, and it’s also the joint that gets the least attention until something goes noticeably wrong.

Somewhere in your fifties, exercise starts to feel like a different conversation. Not because you’ve stopped being capable, but because what you’re trying to preserve has shifted — from building fitness to keeping the body reliable. The knees are more of a consideration. Recovery takes longer. And a lot of the advice out there is written for people twenty years younger, with nothing to lose. This article is for information only and does not constitute medical advice.

Most people notice it in small ways first — the knees that take a moment to warm up in the morning, the hip that complains after a long drive, the shoulder that starts registering things it used to ignore. These are not dramatic events, and they rarely prompt an immediate trip to the GP. Instead, people quietly adjust: they stop going down stairs quite so freely, they give up the allotment work they enjoyed, they choose a different chair. The adjustments accumulate. What current clinical guidance now reflects is that regular, appropriate movement — the kind a physiotherapist would

There is a particular kind of loss that happens quietly — not all at once, but in small adjustments. You stop taking the stairs without quite deciding to. You park closer than you used to. A walk that once felt comfortable now requires a day’s recovery. Mobility does not tend to disappear suddenly; it retreats in increments small enough that each one feels manageable. By the time the cumulative effect is obvious, the gap between where you are and where you were can be considerable. Research published in the BMJ found that a structured physical activity programme reduced major

Joint pain and poor sleep tend to arrive together, and most people assume the pain comes first — that aching knees or hips are simply what keeps them awake. The research tells a more complicated story. There is now reasonable evidence that disrupted sleep does not just follow joint deterioration; in a significant proportion of cases, it may precede and contribute to it. A large study drawing on data from hundreds of thousands of adults found that people sleeping fewer than six hours a night were 41% more likely to develop knee osteoarthritis than those sleeping seven hours —
