The short answer: Change position about every 30 minutes: stand, walk, or stretch for one to two minutes. The UK Health and Safety Executive prefers short, frequent breaks, such as 5 to 10 minutes every hour, to long, rare ones. Research does not pin down one perfect interval, so breaking up long spells matters most.
Key takeaways
- A break about every 30 minutes is a sensible rule of thumb, not a proven threshold.
- Short, frequent breaks beat occasional long ones, according to HSE guidance.
- Active breaks may help back pain, but the evidence is still limited.
- Standing all day is not the aim. Changing position is.
- Back pain with numbness, bladder or bowel changes, or after a fall needs medical help.
How often should you stand up from your desk?
About every 30 minutes, for one to two minutes. That is a practical target, not a proven cut-off. The HSE gives no fixed timing but advises short, frequent breaks over longer, rarer ones, with 5 to 10 minutes every hour as its example [1].
In one study covered by a Cochrane review, short breaks of 1 to 2 minutes every half hour cut sitting by about 40 minutes per working day [5]. The evidence was low quality, so treat it as encouraging, not settled.
Here is a schedule you can copy:
Phone calls and meetings make natural break points [1]. For more on this, see our guide for desk workers.
How long can you sit before it becomes a problem?
There is no single safe number. The better question is how long you sit without interruption.
The UK Chief Medical Officers advise adults to minimise sedentary time and, where physically possible, to break up long periods of inactivity with at least light physical activity [3].
One large US study followed 7,985 adults aged 45 and over. Those whose sitting came in the longest uninterrupted stretches had a higher risk of death from any cause than those with the shortest (hazard ratio 1.96, 95% confidence interval 1.31 to 2.93) [6]. It measured death risk, not back pain, and it was observational, so it cannot prove cause.
Does standing up actually help back pain?
It may help, particularly if the break involves moving. A systematic review of 11 trials in office workers (Waongenngarm and colleagues, 2018) found moderate-quality evidence that active breaks with a change of posture benefit pain and discomfort. Evidence on pain overall was low quality and mixed. Breaks did not harm productivity [7].
A later trial of 193 office workers at high risk of back pain, in Thailand, followed them for six months. New low-back pain developed in 9% of the active-break group and 7% of the posture-shift group, compared with 33% of the control group [8].
What this means: breaks look promising, but this was one small trial in one country using a purpose-built device. It is not a guarantee.

Is it better to stand all day instead?
No. Sit-stand desks helped people sit less (by about 100 minutes per workday in the short term and 57 minutes over 3 to 12 months), but the evidence was low quality. The Cochrane review found no data on health outcomes such as back pain [5].
Standing still ties you to one position too. Aim for variety: sit, stand, walk, repeat. Our guide to whether a standing desk is good for back pain goes deeper.
What should you do on a break?
Walking is the simplest option. If you only have two minutes and want to loosen up, try this reset. It is a starting point for review.
- Seated cat-cow. Hands on your knees, arch your back gently, then round it. Do 8 slow repetitions. See our cat-cow exercise.
- Seated thoracic rotation. Arms crossed over your chest, turn your upper body to one side, then the other. Do 5 each way. See our thoracic rotation exercise.
- Standing hip flexor stretch. Take a long step back, tuck your pelvis under and lean forward until you feel a mild stretch at the front of the hip. Hold 20 to 30 seconds each side. See our hip flexor stretch.
Stop if you feel sharp pain, pins and needles, or pain spreading down a leg.
Kai, Loosn's AI physio coach, can suggest break moves that suit your pain and remind you to take them. A timer on your phone works just as well.
Hard to remember? Tie breaks to something you already do: a finished email, a new call, a drink. For a stiff back, see why your back aches after a day at your desk. For a stiff neck, try these tech neck exercises. Muscle stiffness after a long sit is common.
When to get medical help
Sitting breaks do not treat serious causes of back pain.
Call 999 or go to A&E if back pain comes with [9]:
- pain, tingling, weakness or numbness in both legs
- loss of feeling around your genitals or anus
- changes in bladder or bowel function, such as difficulty peeing or losing control
- chest pain
- pain that started after a serious accident, such as a car crash or a significant fall
Call 111 or ask for an urgent GP appointment if back pain comes with [9]:
- feeling hot, cold, shivery or generally unwell
- sudden severe pain, or pain that is getting worse quickly
See a GP if your back pain [9]:
- has not improved after a few weeks of home treatment
- does not improve with rest, or is worse at night
- comes with numbness or weakness in one leg, or pain down the leg past the knee
- comes with unexplained weight loss, or you are worried about it
Loosn is not a substitute for assessment when symptoms are severe, getting worse or unusual.
FAQ
Are employers required to give desk workers breaks?
For people who use display screen equipment, the HSE says employers must plan work so there are breaks or changes of activity. It adds that there is no legal guidance on how long or how often breaks should be. Short, frequent breaks are preferred, and users should ideally choose when to take them [1].
What counts as a break from sitting?
Anything that gets you out of the same position: standing, walking, climbing stairs, or at least stretching and changing posture [1]. Light physical activity is what the UK Chief Medical Officers advise for breaking up long inactive spells [3]. A one- to two-minute walk counts.
How long should I stand at a standing desk?
Experts writing in the British Journal of Sports Medicine suggest desk workers build up to about 2 hours a day of standing and light activity, then work towards 4 hours [4]. That total is spread through the day, not done in one go. Mix it with walking and sitting.
Is it enough to exercise after work if I sit all day?
Exercise matters, but it may not cancel out long, unbroken sitting. The NHS says you can meet your weekly activity target and still be at risk of ill health from sitting too much [2]. Doing both helps: regular activity and regular breaks during the working day.
