How to Deal With Constant Interruptions at Work

The cost of an interruption is not just the time it takes. It is the time needed to get back to where you were. Research by Gloria Mark at UC Irvine found that after a distraction, it takes around twenty-three minutes to fully resume a complex task. Most people have no idea the number is that high, which is why the impact of a fragmented day is so consistently underestimated.

If you are being interrupted a dozen times a day, you are potentially spending several hours just recovering. Not in any visible way — you are still sitting at your desk, still appearing to work — but the depth of attention available for anything difficult is dramatically reduced.

Two types of interruption, two different fixes

It helps to separate interruptions into two categories. External ones come from other people: colleagues stopping by, messages arriving, someone asking a question. Internal ones come from you: the urge to check email, the sudden memory of something you need to do, the pull toward an easier task.

Both are real problems, but they need different responses. External interruptions are primarily a communication and boundary challenge. Internal ones are an environment and habit challenge.

Protect specific blocks of time, not the whole day

Trying to be uninterruptible for an entire day is rarely practical and often creates resentment from colleagues who legitimately need access to you. A more sustainable approach is protecting specific windows and being fully available outside them.

Two or three hours of focused time in the morning, clearly communicated to anyone who works with you, is enough to do meaningful work. The rest of the day can accommodate collaboration, messages, and whatever else arrives. When people know when you are available and when you are not, they plan around it rather than interrupting constantly.

Make the signal clear

Visible cues reduce interruptions without requiring a conversation every time. Headphones on, even without music, is widely understood as a focus signal. A status update on Slack or Teams that says "focused until 11am" sets expectations. Some people use a physical indicator at their desk.

The signal matters because most interruptions are not urgent. People stop by because it is convenient, not because it cannot wait. A clear signal invites them to make the judgment call about whether it is actually worth interrupting. Most of the time they decide it is not.

Handle internal interruptions with a capture list

A lot of mid-task wandering happens because something occurs to you and you do not want to lose it. A short list — a notepad or a plain text file — gives your brain somewhere to park these things immediately. You write it down in three words and return to the task.

The list matters because the brain treats unresolved things as open loops that demand attention. Writing something down closes the loop temporarily, which is enough to let you continue. At the end of the session you decide what on the list is actually worth acting on.

Build it into your weekly plan

A week planned without focused blocks built in will not have focused blocks. They will be crowded out by meetings, messages, and other people's priorities. The Sunday planning session is where you look at the week ahead and explicitly protect the time you need for the work that actually requires your full attention. Without that step, the intention to focus stays an intention.
