Clutter in the office: why your brain gets tired without you realising it
You started the day early. The coffee was hot, and the first meetings weren’t due until ten o’clock. And yet, by midday, your teams already seem exhausted, for no apparent reason. A few overflowing files, cables lying about, a meeting table that’s never really been cleared. Nothing dramatic. And yet, clutter in the office isn’t neutral for the brain. It constantly demands the brain’s attention, even when nobody notices.
A study published in the *Journal of Neuroscience* by researchers at the Princeton University Neuroscience Institute clearly shows that a cluttered visual environment forces the visual cortex to continuously process irrelevant information, thereby reducing the cognitive resources available for the main task. This is not just a feeling. It can be measured using functional MRI.
What your brain actually does when faced with disorder
The brain does not sort visual information before receiving it. It receives everything, then decides what to process first, and this decision costs energy. This is what McMains and Kastner demonstrated in 2011: when several objects are present in the visual field, they compete for neural representation in the visual cortex. They cancel each other out, which reduces the attention available for each of them, including the screen or document you are trying to focus on.
The more visually cluttered the environment, the more energy the brain has to expend to filter out what it isn’t supposed to be looking at. This process is automatic and unconscious. No one in the team experiences it as ‘I’m distracted by the letter tray’, but the neurological cost is very real.
The study also confirmed that people working in organised spaces are less irritable, process information more efficiently and maintain their level of concentration for longer throughout the day.

The invisible cognitive burden: how clutter wears you out without warning
The term ‘cognitive load’ refers to the amount of mental effort a task demands of working memory. This memory is limited: it can only handle a small number of items at any one time. When part of this capacity is taken up by passive visual filtering (processing and discarding what clutters the desk), there is less left for thinking, decision-making, writing and analysing.
This is what researchers call extrinsic cognitive load: a drain on mental energy that does not contribute to the task at hand, but is imposed by the environment. In a visually cluttered workspace, this load can build up throughout the day without anyone recognising it as such.
The practical consequences are well documented: reduced accuracy, less persistence when faced with obstacles, and earlier onset of mental fatigue. This phenomenon is all the more pronounced in open-plan offices, where the field of vision encompasses not only one’s own workstation, but also all neighbouring desks, walkways, noticeboards and communal areas. For teams working to tight deadlines or making frequent decisions, the impact is significant.
5 practical tips for reducing the cognitive load in your space
How Wooh incorporates visual order into its interior design projects
At Wooh, the issue of visual organisation is not treated as a purely aesthetic concern at the end of a project. It forms part of the initial brief that the interior designers draw up with each client. What are the workflow patterns? Who needs to concentrate, and who is in constant contact with others? What needs to remain visible, and what can be tidied away?
The solutions offered vary according to requirements: furniture with built-in storage from Narbutas or Fantoni, partitions to define areas without closing off the space, recessed electrical fittings to eliminate surface cables, and floor coverings to delineate different zones of use. The result is not just more attractive. It is also less cognitively taxing, and this benefit is measurable over time. This approach is reflected in the projects carried out by our design team, where the layout always precedes the choice of furniture.
Frequently Asked Questions
Does a minimalist office really improve work performance?
Yes, and not just because of the motivational effect. The Princeton University study published in the *Journal of Neuroscience* shows that visual clutter forces the visual cortex to process irrelevant information, reducing the cognitive resources available for the main task. An organised space reduces this extrinsic load and allows the brain to devote more energy to what really matters.
How can you organise a professional office to improve concentration?
Start by minimising what is visible on your desk: only items you need during the day should remain within sight. Next, move on to storing documents and accessories out of sight. If space allows, create separate zones for different types of tasks. Finally, tidy away any visible cables and connections: removing them has an immediate impact on the visual clarity of a space.
Is visual clutter more of a problem in open-plan offices than in private offices?
In an open-plan office, one’s field of vision encompasses not only one’s own workstation but also the entire environment: neighbouring desks, aisles and communal areas. This intensifies the competition for neural representation. That is why the design of open-plan offices benefits from including defined areas, enclosed furniture and clear visual focal points.
What types of storage furniture would you recommend for a professional office?
The most effective solutions combine accessibility and discretion: under-desk units with doors, closed mid-height cabinets, and storage built into the workstation itself. The Narbutas and Fantoni brands, available from Wooh, offer comprehensive ranges tailored to SME environments, with finishes that complement the rest of the office furniture.
