Let me talk to you about knee pain.

It’s the time of year when I see more chronic knee pain victims than any other and it happens for two reasons – which I’m going to tell you all about.

If you're in your late 50s or 60s, there’s a good chance you've already experienced something strange happening to your joints when the temperature begins to drop.

They suddenly get that bit more annoying, nagging and painful, on a daily basis. If you’re struggling to put your finger on why it happens every year at the same time, I can assure you you’re not the only one it’s happening to.

The sensation that knee joints appear to become more stiff, ache more, clunk more and even swell more when the temperature drops is one that many men and women aged 50+ can hold their hands up to having suffered from.

There are many reasons why your joints appear to be more problematic in winter. Two reasons are the low temperature, which naturally restricts your circulation, and the fact that you’re much less likely to be active in winter, further restricting the blood supply. Yet keeping joints mobile by being active is the equivalent of spraying WD40 on the stiff and rusty joints of an old bike or car – it’s essential oil that makes the ride much easier and smoother.

And here’s the thing that many people in their 50s and 60s fail to grasp - the long winter months and a sustained period of inactivity can be the root cause of what I call ‘all of a sudden’ lifelong knee pains. You see, if your muscles get a long rest in winter, there’s a chance they’ll waste away to the point where they will not be able to support your knees as they once could when you start up again in the spring, when you feel more like being active. And without the support of the muscles, knees are much more likely to end up arthritic.

Here's what goes on: after a long winter of inactivity and hibernation, the temptation is to automatically begin to exercise again when the good weather and light nights come around.

But your muscles may not be strong enough to suddenly start exercising again safely after so much rest. Not if you’ve shut down these muscles down for six whole months!

The harsh reality for many knee pain victims is that most of their problems will be added to by a long winter break from activity. First you experience a lull in your exercise and then you think it’s okay to go back to doing all the things you did before the break. So, with that in mind, here’s a big tip to help you avoid making this mistake.

Seize any and every opportunity you have during winter to get active, keep joints mobile and vital muscles strong – things like swimming, bike-riding, yoga and pilates will help.

If you’re lucky, you’ll never get to know what life with “dodgy knees” is like if you hadn’t. It’s definitely something to think about over the next few weeks as you most likely spend more time doing less as the temperature drops even lower. Have a wonderful Christmas and I wish you all the very best for 2015.
