A timeboxed block of single-tasking: one task, a set time (often 25 minutes), notifications off and your phone out of reach, then a short break.

Why it may help

A time limit makes starting easier and protects the work from interruptions and switches, which cost more focus than they seem to.

When to use it

• you need to concentrate on something important
• a task keeps expanding or never finishes
• your day is full of interruptions

Helps with

• Focus
• Deep work
• Starting a big task

How to do it

1. Choose one task and decide what you will do in this session.
2. Put your phone in another room or a drawer, and close tabs you don’t need.
3. Work on only that task until the timer ends. If a thought pops up, jot it down and return. (about 1500 seconds)
4. Take a five-minute break away from the screen. (about 300 seconds)

What the evidence says

Practical technique: A widely used, low-risk practice drawn from established approaches, but not tested much on its own. Its value is mostly that it is simple and harmless to try.

What was found

Research shows switching between tasks has real costs, and single-tasking avoids them. Some studies suggest structured breaks reduce fatigue.

What is uncertain

The specific 25-minute format (the Pomodoro method) has little direct research; the best length varies by person and task.

Who it may not suit

If 25 minutes feels impossible, start with 10. Longer isn’t better if it means you won’t start.

Where this comes from: Attention and task-switching research; Procrastination research.

Afterwards, ask yourself

How much did you get done in one protected session?
