You block out the morning for the one piece of work that actually matters. By eleven you have answered fourteen messages, sat through a call that could have been three lines of text, and touched the real task twice. Nothing went wrong. That was a normal day.
Focusing at work is a harder problem than focusing anywhere else, and most advice skips the reason. At home you can put the phone in a drawer and shut the laptop. At work the laptop is the job, the messages are the job, and the person breaking your concentration is a colleague you need something from on Thursday. Here is what research inside real workplaces found, and what to do with it.
Work is fragmented by design
Gloria Mark and her colleagues at the University of California, Irvine observed 24 information workers minute by minute in their own offices. People spent about 11 minutes in one working sphere, meaning a single coherent thread of work, before switching to another, and 57% of those stretches were interrupted before they ended.
That is a description of the environment, not a verdict on the people in it. A job is a set of open threads, each with a deadline and a queue of people needing something from it. Fragmentation is the resting state, and concentration runs against the grain of the room. The full price of a single interruption is here.
The open office interrupts you twice
The obvious cost of an open office is the colleague at your shoulder. The measured cost is stranger.
Laura Dabbish, Gloria Mark and Victor González analysed 889 hours of observed task switching from 36 people across three technology companies. They found that people in open office environments interrupt themselves at a higher rate. Not that they were interrupted more often by others. That they generated more of their own interruptions.
The mechanism showed up in the same data: external interruptions in one hour significantly increased self-interruptions in the following hour. Being pulled away teaches you to pull yourself away. An hour after the tap on the shoulder you are producing the interruptions on your own, and the room no longer has to do anything.
So the honest answer to how do I focus in an open office is not headphones. The room has trained a habit into you, and by mid-morning that habit is the larger half of the problem.
Punti chiave
- Work is fragmented by default: about 11 minutes on one thread before switching, and 57% of those stretches interrupted.
- Open offices raise self-interruption, so the habit outlasts the noise.
- Batching messages is tied to higher rated productivity, but not to lower stress.
- Distance beats resolve: another room beats a bag, which beats the desk.
- Defend one protected stretch rather than the whole day.
Four things that hold
None of it is exotic, and all four get decided while you are calm, before the day tests them.
1. Pick one goal you could say out loud
Not "work on the deck." One sentence a colleague would understand: the pricing section, finished well enough to send. A session with a stated target is much harder to drift out of, because drifting becomes visible while it is happening. Without one, every arriving message looks like a reasonable next thing to do, because nothing is competing with it.
2. Batch your messages instead of grazing them
Mark and colleagues tracked 40 information workers for 12 workdays using computer logs, biosensors and daily surveys. The longer the daily time on email, the lower people rated their own productivity and the higher their measured stress. Checking in defined blocks rather than continuously was associated with higher rated productivity.
One honest caveat from the same study: despite the widespread claim, the researchers found no evidence that batching lowers stress. Treat it as a way to get more done, not as a way to feel calmer. Two or three checks across a morning covers almost any role, and anything that genuinely cannot wait will reach you by phone.
3. Make the block visible to other people
A closed door is a signal. In an open office you have to build one: a recurring block in the shared calendar with a real name on it, a status that says when you are back, headphones the team has agreed mean not now. A colleague should be able to tell at a glance that interrupting you costs something, and the public commitment makes it awkward to abandon quietly.
Say when you will be available rather than that you are unavailable. "Back at 11" gets respected. "Do not disturb" gets tested.
4. Put the phone where reaching it costs you a walk
Researchers at the University of Texas at Austin ran experiments with nearly 800 people, measuring available cognitive capacity while a silenced phone sat on the desk, in a pocket or bag, or in another room. Another room scored best, pocket or bag next, the desk worst. Face up or face down made no measurable difference, and neither did switching the phone off.
At work, another room usually means a locker, a drawer on the far side of the floor, or a bag you must stand up to reach. The distance does the work, not the gesture. The same evidence applied to revision is here.
What one protected stretch is worth
Mark, Stephen Voida and Armand Cardello cut email off entirely for five workdays for 13 people inside an organisation, tracking them with computer logs and wearable heart rate monitors. Without email, people switched windows less often and stayed in each one longer, and stress measured through heart rate variability was lower.
Nobody is suggesting you cut off email for a week; the study did it so you would not have to. What it establishes is the size of the prize, and that it comes in fractions. One protected hour is a smaller version of the same effect.
The part you cannot fix
Slack and email are not distractions in your job, they are part of it, and other people depend on them. No setup makes them disappear, and advice telling you to block them comes from someone who has not seen your calendar. The realistic target is not a day without messages. It is one or two protected stretches inside a day that otherwise stays open.
The limitation nobody mentions
Mark, Mary Czerwinski and Shamsi Iqbal ran a field study in which 32 information workers used software to block online distractions for a week of ordinary work. Focus rose significantly on a validated measure, and in interviews people named the thing that had stopped: rabbit-holing, the message that becomes an article that becomes a reply that becomes twenty minutes. The software did not make anyone stronger. It removed the first step of the chain.
The results were not unanimous, and the paper says so plainly: 17 people reported more benefits, 10 more costs, 4 were neutral, and enjoyment went down. Some, mostly those already in control of their work, took fewer breaks and reported more strain.
Underneath all of it sits a structural problem no study can solve for you. Almost every block you install at work runs on the machine you work from, which is the same machine you undo it on. Four seconds, one dialog, the same person lifting the limit the moment it starts to bite. That is not a block, it is a note to yourself, and it fails at the only moment it was ever needed: the ten minutes before the meeting you are dreading. Why the built-in tools have this shape is here.
Norma is one way to close that gap. It is a stainless-steel disc you keep on the desk: scan it with your iPhone and the apps you chose disappear, scan it again and they come back. Because the off switch is an object rather than a menu on the phone, leaving the disc in a drawer is the whole enforcement mechanism. It blocks distracting sites on a Mac too, which is the half most workplace advice skips, since the tab you lose an afternoon to is on the computer you were hired to use. One purchase, no subscription.
Protect one block of the day.
Scan the disc, and the apps and sites that cost you disappear until you scan again.

- How do I focus at work?
- Decide one goal you could say out loud, protect a single stretch of the day for it rather than the whole day, batch your messages into two or three defined checks instead of grazing them, and put your phone somewhere that costs you a walk. Focus at work is mostly a property of the setup, not of the person, because the environment is built to fragment attention by default.
- How can I stop getting distracted at work?
- Work on the chain rather than the individual distraction. In a field study at UC Irvine and Microsoft Research, information workers who used blocking software for a week described the thing that stopped as rabbit-holing: the message that becomes an article that becomes a reply. Remove the first step and the rest of the chain does not happen. Trying to stop yourself at step four almost never works, because by then you are already somewhere else.
- How do I focus in an open office?
- Headphones and a booked room help less than people expect. Research analysing 889 hours of observed task switching across three technology companies found that people in open offices interrupt themselves at a higher rate, and that being interrupted in one hour significantly raised self-interruptions in the next. The room trains a habit into you, so the fix has to address your own switching, not only your colleagues': one stated goal, a visible signal that says when you are back, and messages checked in blocks.
- How do I do deep work when my job is full of meetings?
- Stop trying to defend the whole day and defend one stretch of it. A study that cut email off entirely for five workdays found people switched windows less, stayed in each one longer, and had lower stress measured through heart rate variability. Nobody can work like that permanently, but it shows what a protected block is worth, and blocks are available in fractions. Ninety minutes in the calendar with a real name on it beats an aspiration to be undisturbed.
- How do I stop checking my phone at work?
- Distance does more than willpower. Experiments at the University of Texas at Austin with nearly 800 people found that those whose phones were in another room scored best on measures of available cognitive capacity, ahead of pocket or bag, ahead of the desk. Every phone was silenced, and it made no measurable difference whether the phone was face up or face down, or on or off. At work that usually means a locker, a bag you would have to stand up to reach, or a block you cannot lift from the phone itself.
- Why can't I concentrate at work anymore?
- Because the job is structured to prevent it. Observing 24 information workers in their own offices, researchers at UC Irvine found people spent about 11 minutes in one thread of work before switching, and that 57% of those stretches were interrupted before they ended. That is not a discipline problem, it is a description of the environment. Concentration at work is something you have to build against the grain rather than something the day gives you.
