Microbreaks: how often to move during the workday

Microbreaks are short pauses from screen work, from under a minute to a few minutes, taken often through the day. Almost every ergonomics body recommends them. Where they differ is the number: every 20 minutes, every 30, every hour. This page looks at where those numbers come from, what the trials found, and how sit-stand desks and reminder apps fit in.

What counts as a microbreak?

Anything that interrupts sitting still at the screen. The UK Health and Safety Executive (HSE) says breaks or changes of activity “should allow users to get up from their workstations and move around, or at least stretch and change posture” (HSE). It points out that in most jobs you can switch to other tasks, such as meetings or phone calls, and that these changes count.

OSHA’s list is similar: small adjustments to your chair or backrest, standing up and walking around for a few minutes, and doing some tasks standing, such as reading, phone calls and meetings (OSHA). Cornell University adds that “simply standing is insufficient” and that moving is what matters (Cornell).

Looking away from the screen also counts as a break for your eyes, even if you stay seated. That is covered further down.

How often should you take microbreaks?

The guidance converges on “short and often”, with different numbers:

• UK HSE: there is “no legal guidance about how long and how often breaks should be”, but “5 to 10 minutes every hour is better than 20 minutes every 2 hours”. Ideally, you choose when (HSE).
• US OSHA: “Every hour, take a five-minute break from computer tasks”, and frequent short breaks are desirable (OSHA).
• Cornell University: about every 20 to 30 minutes, take a posture break and stand and move for a couple of minutes. As a pattern, Cornell suggests 20 minutes sitting, 8 minutes standing and 2 minutes moving (Cornell).
• CDC/NIOSH: studies show short breaks every hour help reduce discomfort for computer workers (CDC).
• WHO: recommends reducing sedentary behaviour for everyone, but found the evidence was not enough to set a threshold (Bull et al., 2020).

None of these numbers comes from a large trial comparing intervals head to head. A Cochrane review found no trials at all comparing different break lengths (Luger et al., 2019). A reasonable reading of all of this: change position at least every half hour, get up properly at least once an hour, and don’t worry about the exact minute. HSE’s other piece of advice is worth keeping in mind: change activity before you get tired, rather than to recover (HSE INDG36).

What the research on microbreaks shows

The best evidence is for short-term comfort, and it is fairly consistent:

• NIOSH field trials. In a study of 42 data-entry workers, adding a five-minute break to each hour that had none (20 extra minutes a day) lowered discomfort in several parts of the body and eye strain, without reducing data-entry performance (Galinsky et al., 2000). A follow-up with 51 workers found the same, and data-entry speed rose enough that output held up despite 20 fewer minutes of work time (Galinsky et al., 2007).
• Break timing. In a trial of keyboard workers, microbreaks reduced discomfort in all the body areas studied, particularly when taken every 20 minutes, and did not hurt productivity (McLean et al., 2001).
• Energy and tiredness. A meta-analysis of 22 study samples with 2,335 people found that microbreaks gave small boosts to vigour and small reductions in fatigue. The effect on overall performance was not statistically significant (Albulescu et al., 2022).
• New pain. In a trial of 193 office workers in Bangkok at high risk of neck and back pain, new neck pain over six months affected 17% of those encouraged to take active breaks, 17% of those encouraged to shift posture, and 44% of the control group (Waongenngarm et al., 2021). It is one trial, mostly of women, and needs repeating.

The evidence for long-term prevention is weaker. A Cochrane review rated the evidence that supplementary breaks reduce neck and arm discomfort as very low quality (Hoe et al., 2018). Another, looking only at workers without symptoms, found six small trials with 373 people, all at high risk of bias, and low-quality evidence that extra breaks may make no considerable difference to pain or discomfort. Active and passive breaks did not clearly differ either (Luger et al., 2019).

The fair summary: in the short term, breaks tend to make long days at a screen less uncomfortable and less tiring without costing output, though the trials are small. Whether they prevent neck pain or lower back pain over years is not yet shown. What you do with a break may matter. The evidence that short, regular strengthening helps the neck and shoulders is in is two minutes of exercise enough?, and the evidence on stretching is in do stretches help neck pain from desk work?

Do sit-stand desks help?

They are very good at one thing: cutting sitting time.

• A Cochrane review of 34 studies found sit-stand desks reduced sitting at work by about 100 minutes per workday in the first three months, and by about 57 minutes at three to twelve months. The evidence was low quality, and there was none beyond a year (Shrestha et al., 2018).
• In a trial with 146 office workers in an NHS trust in England, the intervention group got a height-adjustable desk plus coaching, feedback and goal setting. At 12 months they sat about 83 minutes less per workday than the control group, and fewer reported neck and upper limb problems in the previous week, though the proportion with problems over the whole year did not differ (Edwardson et al., 2018).

The effect on pain is smaller and less certain:

• A meta-analysis of eight studies found a small reduction in low back discomfort among pain-free workers using sit-stand desks (Agarwal et al., 2018).
• In 23 office workers with overweight or obesity, switching between sitting and standing every 30 minutes for five days in a simulated office, compared with sitting all day, reduced fatigue and cut low back discomfort by about a third (Thorp et al., 2014).
• The one sit-stand trial in the Cochrane review of neck and arm problems found no effect on upper limb pain (Hoe et al., 2018).

Cornell adds two cautions. Standing takes about 20% more energy than sitting and is more tiring, and in its experience many people end up standing for 15 minutes or less a day, with most back to sitting all the time after a month (Cornell). The SMArT Work trial suggests support and coaching can keep the habit going.

So treat a sit-stand desk as a tool for changing position, not a goal to stand all day. Set it up properly at both heights; the desk height calculator gives a starting point for each.

Do reminders and apps help?

A little, and they are cheap.

• A 2025 review of 18 trials with 1,164 office workers found that computer prompts reduced sitting by about 12 minutes per workday and added about 1,000 steps. Effects on musculoskeletal and other health outcomes leaned the right way but were not statistically significant (Leppe-Zamora et al., 2025).
• The Cochrane review on reducing sitting found mixed results for computer prompts, with one trial showing a larger reduction at three to twelve months (Shrestha et al., 2018).
• HSE notes that break-monitoring software can remind people to take breaks, but employers are still responsible for planning work so that breaks happen (HSE). The Chartered Society of Physiotherapy suggests simply setting an alarm (CSP).

What about the 20-20-20 rule for your eyes?

The rule says to look at something about 20 feet (6 metres) away for 20 seconds every 20 minutes. The evidence is mixed. In 29 computer users with eye symptoms, software reminders based on the rule reduced eye strain and dry eye symptoms over two weeks, but the benefit was gone a week after the reminders stopped (Talens-Estarelles et al., 2023). In 30 young adults doing a demanding 40-minute reading task, 20-second breaks every 5, 10 or 20 minutes made no difference to symptoms (Johnson & Rosenfield, 2023). Cornell suggests looking away from the screen for a minute or two every 15 minutes (Cornell), and HSE says to look into the distance from time to time and blink often (HSE INDG36). Glare and screen position matter too; see how to set up your monitor.

How to make microbreaks a habit

• Use the breaks you already have. Phone calls and meetings count as changes of activity (HSE), and so does a walk to refill your water. Taking calls away from the desk is one the CSP suggests (CSP).
• Make standing the default for some tasks. Reading, calls and short meetings are the easiest (OSHA).
• Tie a reminder to an action. A prompt only helps if you act on it, so give each one a job, such as standing up for the next call.
• Plan more at home. Working from home removes many of the natural breaks of an office; the home office guide covers that.
• Plan for your busiest weeks. Breaks are easiest to drop when the work piles up, as it does for accountants in busy season or for graphic designers close to a deadline. Decide on them before the crunch starts.
• If you manage a team, HSE’s point is that breaks have to be planned into the work, not left to willpower. See Bavelu for teams.

If you want your breaks to be more than standing up, Bavelu has desk routines of two to four minutes, guided by your AirPods’ motion sensor and designed and filmed by physiotherapists. The same AirPods can let you know when your head starts leaning towards the screen between breaks (how AirPods posture tracking works).
