Working from home often means sitting longer and moving less than you did at an office. The most useful fix isn't a new chair — it's breaking up the sitting.
The short version
- An office day has movement built into it that quietly disappears at home.
- Research links longer sitting time, fewer breaks, and sitting very still with more low back pain.
- The problem is usually holding any position too long, rather than one "wrong" posture.
- Getting up every 30 minutes does more than the rest of the list put together.
Why it happens
An office day has movement built into it that you barely notice. Walking to the station. Going to find someone. Standing in a queue at lunch. At home, all of that quietly disappears. You can go from bed to desk in thirty seconds and stay there.
The research points at the amount of sitting, not just how you sit. A review of studies on office workers found that longer sitting time, fewer breaks, and sitting very still were all linked with more low back pain. A study of nearly 45,000 employees found that sitting almost all the time at work, without breaks, was linked with more reported back and neck pain.
Which brings us to posture. It's tempting to blame the way you sit, and a badly set up desk really can make you uncomfortable. But no single "correct" position holds up for hours. The problem is usually holding any position too long. A trial in office workers found that active breaks and changing position helped with neck and low back pain — the change itself was doing the work. The same thing turns out to be true higher up the spine, as our piece on posture and neck pain explains.
⚠️ When to see a doctor in person
Get medical help the same day if you have numbness around your groin, bottom, or inner thighs, if you've lost control of your bladder or bowels, or if your legs feel weak or are getting weaker.
- Book an appointment if the pain runs down your leg past the knee, or your foot feels numb or heavy
- Book an appointment if you have a fever or unplanned weight loss
- Book an appointment if it isn't improving after about 6 weeks of staying active
Desk-related back pain usually settles once you move more.
Starter routine
None of this needs equipment. The point is variety, not effort.
Set a timer if you need to. Stand, walk to another room, and come back. This one change does more than the rest put together.
From your desk chair, stand up and sit down slowly, about 3 seconds each way. Keep your knees pointing over your middle toes.
Stand up, put your hands on your lower back, and lean gently backwards. Hold 2 seconds. Small movement, no forcing.
Lie on your back, knees bent, feet flat. Let both knees drop slowly to one side, then the other. Good at the end of the day.
The easiest movement you'll add all week.
Mild discomfort that settles quickly is fine. Sharp pain means ease off.
A word on the desk itself
You don't need to spend money. Getting your screen up to roughly eye level, your feet flat on the floor, and your forearms level with the desk will cover most of it. A stack of books works as a monitor stand. If you have a standing desk, use it in blocks — swapping between sitting and standing is more useful than picking one and staying there.
Progression note
Start with the 30-minute break rule for a week before adding anything else. It's the change most likely to stick and the one with the clearest link to how you feel. After that, build up walking — aim for a short walk at the start and end of your working day, roughly where your commute used to be.
The bottom line
Back pain that showed up when you started working from home is usually about how much you sit, not how badly. Breaking up long sitting with short, frequent movement is the change with the best support behind it. If mornings are the worst part, see lower back stiffness after sleeping. Get checked in person if you have leg weakness, numbness around the groin, bladder or bowel changes, or pain that isn't settling.
