Back pain can be frustrating when much of your working day is spent at a desk. It can be tempting to blame your chair, your posture or simply the number of hours you spend sitting.
But the relationship between office work and low back pain is more complicated than that.
Research in office workers has found associations between low back pain and factors such as longer sitting periods, fewer breaks and spending more time sitting relatively still. However, findings for total sitting time are inconsistent, and an association does not mean that sitting is damaging your back.
So, what should you actually do if your desk job and your back aren't getting along?
Does sitting all day cause low back pain?
Not necessarily.
A 2025 review of 22 studies involving more than 7,800 office workers found mixed results for total sitting time and low back pain. The relationship was more consistent for sitting behaviours such as taking fewer breaks and spending longer periods relatively still.
Importantly, much of this research is observational. It can identify associations, but it cannot establish that prolonged sitting itself causes low back pain.
That doesn't mean sitting can't make your back uncomfortable. If your symptoms increase after being in one position for a long time, changing position or moving around may help. But discomfort after sitting doesn't necessarily mean you are damaging your spine.
Is there a ‘correct’ sitting posture?
Probably not one that everyone needs to use.
You may have been told to sit perfectly upright, keep your shoulders back or maintain a particular curve in your low back.
Research has found some differences in posture between people with and without low back pain, but results vary considerably between studies and do not establish that a particular posture causes pain. A recent systematic review and meta-analysis concluded that no firm conclusions could be made about most static postural differences.
Rather than trying to hold one supposedly perfect posture all day, aim for working positions that feel comfortable and change position when you want to.
Should you take breaks from sitting?
Regularly changing position is reasonable, particularly if sitting still for a long time makes you uncomfortable.
Research in office workers suggests that fewer breaks and more static sitting may be associated with low back pain. However, there isn't good evidence for a ‘magic’ schedule, such as needing to stand up every 20 or 30 minutes.
Practical options include:
- getting up to refill your water bottle
- walking while taking a phone call
- standing during part of a meeting
- taking a short walk between tasks
- simply changing your sitting position.
The goal isn't to constantly interrupt your work because sitting is dangerous. It is simply to give your body some movement and variety throughout the day.
Do standing desks help?
They can be useful, but they aren't a cure for low back pain.
Sit–stand desks can reduce sitting time and may reduce low back discomfort for some people. However, prolonged standing isn't necessarily better for your back than prolonged sitting.
A standing desk is therefore best thought of as another position you can work in, rather than a healthier posture that needs to replace sitting.
What about ergonomics?
It makes sense to have a workstation that allows you to work comfortably.
This might involve adjusting your chair, desk, screen, keyboard or mouse if their current positions are uncomfortable or make your work unnecessarily difficult.
However, there is limited evidence that any particular chair or ergonomic setup can prevent back pain. Workplace interventions tend to have modest or uncertain effects, and relying on ergonomics alone is unlikely to be the answer.
So, make your workstation comfortable – but don't feel that you need millimetre-perfect positioning to protect your back.
What exercises are best for office workers with low back pain?
There is no single ‘best’ exercise for low back pain.
For persistent low back pain, exercise is recommended by major clinical guidelines and should be individualised to your preferences, abilities and goals.
This could include:
- walking
- running
- cycling
- swimming
- Pilates
- resistance training
- sport.
You don't necessarily need special ‘back exercises’. For many people, improving their overall strength, fitness and physical capacity is a useful goal.
What you enjoy, what you want to get back to doing and what you can perform consistently all matter.
What if your low back pain has only just started?
You don't necessarily need a complicated exercise program.
For acute non-specific low back pain, specific exercise therapy does not appear to provide a clinically important benefit compared with no treatment or placebo.
That doesn't mean you should rest.
Australian clinical guidance recommends staying active and continuing or returning to your usual activities, including work, as soon as reasonably possible. Prolonged bed rest should be avoided.
You may temporarily modify activities that are particularly uncomfortable and gradually build them back up as your symptoms settle.
When should you see a physiotherapist?
Many episodes of low back pain improve over time without intensive treatment.
However, seeing a physiotherapist may be useful if your back pain:
- isn't improving
- keeps returning
- significantly affects your work or daily activities
- stops you from exercising or doing things you enjoy
- leaves you unsure about what you can safely do.
A physiotherapist can assess your individual situation and help you understand your symptoms, stay active and gradually restore your confidence and capacity.
When should back pain be checked more urgently?
Most low back pain isn't caused by a serious medical condition.
However, seek appropriate medical assessment if you develop concerning symptoms such as significant trauma, fever or feeling systemically unwell, unexplained weight loss, progressive weakness or neurological symptoms, or new changes to bladder or bowel control or sensation around the groin.
If you're concerned about your symptoms or unsure what they mean, speak with an appropriately qualified health professional.
The bottom line
If you work at a desk and have low back pain, you probably don't need to find the perfect chair, sit perfectly straight or avoid sitting altogether.
Instead:
- find comfortable working positions
- change position and move throughout the day when practical
- stay physically active
- exercise regularly, particularly if symptoms persist
- continue or gradually return to your usual activities
- seek individual assessment if your symptoms aren't improving or you're concerned.
The goal is generally not to protect your back from normal movement, but to stay active and gradually build your tolerance and capacity.
If low back pain is affecting your work, exercise or daily life, we can help assess your individual situation and develop a plan to get you moving confidently again.
