Pomodoro Technique: How It Works and What to Do on Breaks

How the Pomodoro Technique works

Francesco Cirillo started developing the method in the 1980s as a university student. He challenged himself to focus for a short stretch using a tomato-shaped kitchen timer, and "pomodoro" is Italian for tomato. Penguin Random House published his book on the method in 2018.

The basic cycle looks like this:

1. Pick one task. Write down what you will work on.
2. Set a timer for 25 minutes. That interval is one "pomodoro."
3. Work only on that task until the timer rings.
4. Take a 5 minute break.
5. Repeat. After four pomodoros, take a longer break, usually 15 to 30 minutes.

Part of the cycle	Classic length	What you do
Pomodoro	25 minutes	One task, no switching
Short break	5 minutes	Step away from the work
Long break	15 to 30 minutes, after four pomodoros	Rest properly, eat, walk

The official Pomodoro Technique site describes the method as three habits: plan your work and estimate how much effort it needs, focus on one activity at a time with regular breaks, and reflect by comparing your estimates with what really happened. The timer is the part most people know, but the planning and reflection are what help you get better at estimating your work over time.

Why people use it

The appeal is simple. A 25 minute block is short enough to start even when a task feels big or dull, and the timer gives you a clear finish line. Counting pomodoros also shows you how long tasks really take, which makes planning the next day more honest.

The fixed rhythm also takes one decision off your plate. You don't have to judge when you have earned a break. The timer decides.

What research says

There is surprisingly little direct research on the Pomodoro Technique, and the best recent study is a useful reality check.

In a 2025 experiment, Smits, Wenzel and de Bruin had 94 university students study for two hours. One group used Pomodoro breaks (four 25 minute blocks, each followed by a 5 minute break), one used Flowtime (work as long as you can focus, then take a break sized to the block), and one took breaks whenever they wanted.

• Productivity: no significant difference between Pomodoro and self-chosen breaks. Task completion was about 69% with Pomodoro and 70% with self-chosen breaks.
• Flow: no significant difference between the groups.
• Fatigue and motivation: in the Pomodoro group, fatigue rose faster and motivation dropped faster over the session than in the self-regulated group.

The authors point out limits: a small sample that was mostly women, and a session of only two hours. So the fair summary is this: the 25/5 rhythm isn't magic, and taking breaks when you need them worked at least as well in this study. Pomodoro is still useful if you tend to skip breaks or struggle to start, because it makes both automatic.

If the fixed rhythm feels wrong for your work, look at Pomodoro alternatives like 52/17, Flowtime and time blocking.

What to do on your breaks

Here is where most people waste the technique. Checking messages or scrolling your phone during a 5 minute break keeps you seated and keeps your attention on screens.

A 2022 meta-analysis of 22 study samples found that micro-breaks of 10 minutes or less raised vigor and lowered fatigue. Several of the breaks studied were physical, such as stretching and Qigong. The same review found no overall effect on performance, though breaks helped more on some kinds of tasks than others. For more on that, see how micro-breaks at work lower stress.

Good break activities:

• Stand up and stretch. Neck, shoulders, wrists and hips take the most strain at a desk.
• Walk. To the kitchen, around the room, outside if you can.
• Look at something far away. Give your eyes a rest from the screen.
• Refill your water. It also gets you moving.

Activities to skip during short breaks: email, chat, news and social media. Save them for a planned slot or your long break.

Breaks are also a natural cue to stop sitting. If you want a target, read how often to get up from sitting.

How to start today

1. Choose a timer. A phone timer works. A dedicated app saves you from resetting it each round. Pomodoroll is a free Pomodoro timer with guided desk stretches between focus and break: after each focus session it walks you through a short stretch, most of them 60 seconds, before your break starts.
2. Make a short list of tasks for the day. Break anything large into pieces that fit in one or two pomodoros.
3. Run your first four rounds and note how many pomodoros each task took.
4. Adjust. If 25 minutes cuts you off too often, try 40 or 50. If you can't stay on task for 25, start with 15. In Pomodoroll you can change the focus and break lengths in Settings. Its default long break is 10 minutes after every four focus sessions, a bit shorter than the classic 15 to 30, so lengthen it if you need more rest.

If you work at a standing desk, alternating between sitting and standing pomodoros is an easy rhythm. Pomodoroll's Start button has a sit/stand switch so you can log which ones you did standing. For how long to stand at a time, see how long to stand at a standing desk.

Common problems and fixes

"The timer breaks my concentration." When you are deep in a task, a ring at minute 25 can feel like an interruption. Lengthen the focus block for that kind of work, or finish your current sentence or thought before you stop. Read how to get into a flow state for more on protecting deep work.

"Some tasks don't fit into 25 minutes." They don't need to. A pomodoro is a unit of effort. A big task takes several, and that count is useful data for planning.

"I skip the breaks." This is the most common way the technique fails. Treat the break as part of the work. Stand up as soon as the timer rings, before you can talk yourself out of it.

"I get interrupted." Write the interruption down and deal with it after the pomodoro, unless it is truly urgent. If you have to stop, restart the timer when you come back.
