Lower Back Pain From Sitting: Why It Happens and What Helps
Many of the office workers we see in Centurion describe the same pattern: comfortable in the morning, aching by mid afternoon, better after a walk. That pattern is typical of load related back pain from sustained sitting.
Why the pain builds through the day
When you sit still, the tissues of the lower back stay under a constant low level load. Blood flow reduces, the discs and joints receive less variation in pressure and the muscles that support your spine slowly fatigue. The body responds with stiffness and ache. This is a signal to move, not usually a sign of damage.
A workable desk setup
Set your chair so your hips are slightly higher than your knees and your feet are supported. Bring the keyboard close enough that your elbows stay near your sides. Place the top of your screen roughly at eye level and about an arm's length away. If you use a laptop all day, add a separate keyboard and mouse so the screen can be raised.
The most useful habit: position changes
The best posture is the next one. Set a reminder every 30 to 45 minutes to stand, walk to fill your water bottle or do a couple of standing back extensions. A sit stand desk helps only if you actually alternate between the two.
If you're in Centurion or Midrand and want personal guidance, our physiotherapist offers same day appointments in clinic in Eco Park, Centurion, or at your home.

Frequently asked questions
Is sitting bad for my back?+
Prolonged unchanged sitting is the issue rather than sitting itself. Regular position changes make a bigger difference than any single chair.
Will a standing desk fix my back pain?+
It may help if you alternate positions, but standing all day can create its own symptoms. Variety is the goal.
How often should I get up from my desk?+
Every 30 to 45 minutes is a practical target, even if it is only for a minute or two.
Do lumbar support cushions help?+
Some people find them comfortable, particularly while driving, but they do not replace movement breaks and strengthening.
