You’ve had a busy morning. Your brain feels foggy. You step away from your desk, pick up your phone, scroll through social media for ten minutes, and go back to work feeling… pretty much exactly the same. Maybe even worse.
If that sounds familiar, you’re not doing anything wrong – but you might be doing the wrong kind of break.
Research suggests that how you spend your downtime at work matters far more than simply having downtime at all. And the things most of us default to – checking our phones, browsing news headlines, catching up on messages – often don’t give our brains the recovery they actually need.
The Science of Effective Rest
Dr Alejandro Lleras, a psychology professor at the University of Illinois, has studied how attention works and why it fades. His research suggests that our ability to focus isn’t like a battery that drains and needs recharging – it’s more like a muscle that stops responding to the same stimulus over time.
What that means in practical terms is that simply stopping work isn’t enough. Your break needs to give your brain something genuinely different to do. If you’ve spent the morning staring at a screen, switching to a smaller screen (your phone) isn’t really a change – your brain is still processing text, images, and decisions. It’s like swapping one treadmill for another.
What Actually Works
The research points to a few types of breaks that genuinely help:
Movement. Even a short walk – five or ten minutes – makes a measurable difference. A study published in the International Journal of Behavioural Nutrition and Physical Activity found that brief walking breaks during the working day improved mood, reduced fatigue, and increased feelings of energy. You don’t need a full workout. A lap around the building or a walk to make a cup of tea counts.
Nature. Looking at or being in green spaces has a surprisingly strong restorative effect. Research from the University of Melbourne found that even looking at an image of a green roof for 40 seconds improved concentration and reduced errors on subsequent tasks. If you can get outside, even better – but a window view or a few minutes in a garden helps too.
Social connection. A genuine conversation with a colleague – not about work – can be one of the most effective break activities. It shifts your brain into a completely different mode and gives you the social interaction that desk-bound work often lacks.
Pro Tip: The 20-20-20 rule is worth trying if you spend long periods at a screen. Every 20 minutes, look at something 20 feet away for 20 seconds. It’s not a full break, but it gives your eyes and your attention a regular micro-reset that adds up over the day.
When to Take Your Break
Timing matters too. Research by organisational psychologists suggests that breaks taken earlier in the day tend to be more restorative than those taken later. By mid-afternoon, fatigue has already built up to the point where a short break is less effective at turning things around.
The practical takeaway? Don’t save your break for when you’re desperate. Take it before you feel you need it. A well-timed 15-minute break mid-morning can do more for your afternoon productivity than a guilty 30 minutes scrolling your phone at 3pm.
What to Avoid
Not all break activities are equal. Research consistently finds that certain activities don’t provide genuine recovery:
Phone scrolling – it keeps your brain in “information processing” mode rather than resting it. Work chat – talking about deadlines and problems during your break isn’t a break at all. Eating at your desk – even if you’re technically on a break, staying in the same environment keeps your brain in work mode.
The common thread? Effective breaks involve a genuine change – in activity, in environment, or in the kind of thinking you’re doing. The bigger the shift from what you were doing before, the more restorative the break tends to be.
Making It Practical
You don’t need to overhaul your entire routine. Start by noticing what you currently do during breaks and asking honestly: does this actually help? If the answer is no, try one small change this week. Walk outside for five minutes instead of checking your phone. Have a chat with someone about something that isn’t work. Stand by a window and look at something green.
Small changes, consistently applied, add up. And the payoff – better focus, more energy, and less of that 3pm slump – is worth the experiment. The NHS recommends adults aim for at least 150 minutes of moderate activity a week – and building short walking breaks into your working day is one of the easiest ways to get there.
