Most of us know, on some (sometimes very overt) level), that sitting all day isn’t great for us. And yet here we are, hunched over a laptop, phone wedged between ear and shoulder, wondering why our backs feel like they’ve aged thirty years since we started working from home.
Would you believe us if we told you that the simple act of sitting isn’t actually the villain. It’s sustained, uninterrupted sitting that causes the problem. And once you understand what’s happening in the body, it’s a lot easier to do something about it.
Your body was built to move
We’re not designed for static positions. When you stay still for long periods, your circulation slows down, oxygen and nutrients aren’t delivered to your tissues as efficiently and your muscles - which normally help keep fluid moving around the body - start to switch off. What happens then is that stiff, uncomfortable, end of the day heaviness that (shockingly) no amount of sofa time sorts out.
What’s actually happening in your spine
When you’re standing, your spine has a natural S-curve that spreads out the load across the whole structure. When you sit – especially with any kind of slump – that curve flattens and more force gets concentrated in your lower back. Do that for eight hours a day, five days a week (a most UK desk workers are) and it really does add up.
Let’s not forget what happens at your hips too. Your hip flexors – including that all important psoas, the deep muscle that connects your spine to your legs – sit in a shortened position whenever you’re seated. Over time, this can contribute to pelvic changes that place even more strain on the lower back. It’s a chain reaction and it starts the moment you sit down.
And it’s not just your back
Desk work tends to pull everything forwards: head, shoulders, chest. Over time, muscles develop memory and start to hold these positions even when you stand up. Which can then start to affect your breathing, create tension in your neck and upper back and alter how you move through everyday life – without you even notice it’s happening.
The ‘perfect posture’ myth
Before you leg it off to buy a lumbar support and sit bolt upright for the rest of your career, it’s worth knowing that there’s no one posture that’s better than all others. Holding any position for too long creates strain. Even standing all day long can cause problems.
What actually helps in movement variability – changing position regularly, distributing load across different tissues and giving your body the variety it was built for.
Small shifts, big difference
You don’t need to overhaul your entire working day. A few small but consistent habits go a long way:
Stand up every 30-60 minutes, even briefly
Walk during phone calls
Take the stairs, walk to get water – the small stuff adds up
If you have a sit-stand desk, actually use it
Notice when you’ve been static for too long – being aware is often enough to kick the habit into action (and if not, set yourself an hourly reminder in your calendar).
When to get some support
Movement changes help a lot of people. But if your back pain is persistent, getting worse, affecting your sleep, or just not shifting despite your best efforts, it's worth getting assessed properly. Back pain treatment can include osteopathy, sports massage, and rehabilitation exercises and a proper assessment makes everything more objective, so you're addressing what's actually going on rather than guessing.
Pain that's been there long enough starts to feel normal. It isn't. And you don't have to just live with it. Give team Fire & Earth a call today and let’s get your back back on track.
