Does the Pomodoro Technique work?

What the research says · By Ilia Usatov · November 2026 · 6 min read

The Pomodoro Technique is the most famous focus method there is: work for 25 minutes, rest for 5, repeat. Millions of people use it, and plenty of others say it breaks their flow. A few recent studies have tested it properly. The short version: planned breaks seem to keep you fresher than breaks you take whenever you feel like it, but the exact 25 minutes are not special.

What the technique is

Francesco Cirillo came up with it as a university student in the late 1980s, using a tomato-shaped kitchen timer. Pomodoro is Italian for tomato. The basic loop:

  1. Pick one task.
  2. Set a timer for 25 minutes and work only on that task.
  3. When it rings, take a short break of about 5 minutes.
  4. After four rounds, take a longer break of 15 to 30 minutes.

Cirillo’s full method goes further than the timer. It also covers handling interruptions, estimating how many rounds a task will take and planning the day and week. Most people only use the timer part, and that is the part researchers have tested.

Study 1: planned breaks against breaks on a whim

In 2023, Biwer and colleagues at Maastricht University followed 87 students during their own study time. One group took breaks whenever they wanted. Two groups had fixed breaks: 6 minutes after every 24 minutes, which is close to a classic pomodoro, or 3 minutes after every 12.

Students who chose their own breaks studied in longer stretches and took longer breaks. They also reported more fatigue and distraction, and less concentration and motivation. All groups got through about the same amount of work. The authors concluded that fixed breaks were better for mood and looked more efficient, since students finished the same tasks in less time.

Study 2: Pomodoro against Flowtime

A 2025 study by Smits, Wenzel and de Bruin compared three approaches in a two-hour study session with 94 students: classic Pomodoro (25 minutes on, 5 off), Flowtime (you work until you lose focus, then rest for a length based on how long you worked) and breaks whenever you like.

This time the results were mixed. All three groups were equally productive, finished the same share of their tasks and reported the same level of flow. In the Pomodoro group fatigue rose faster and motivation fell faster than when students chose their own breaks, but by the end of the session those differences hadn’t changed the overall outcome.

What the wider research on breaks says

A 2022 meta-analysis by Albulescu and colleagues pooled 22 samples with 2,335 people to look at micro-breaks of 10 minutes or less. Such breaks gave a small but reliable boost in energy and a drop in fatigue. The effect on performance overall was too small to be sure of. It showed up for easier tasks, but not for demanding ones. Longer breaks helped performance more, and the authors suggest that recovering from really draining work may need more than 10 minutes.

So does it work?

  • Deciding breaks in advance helps. When students left breaks to chance, they tended to push on until they were tired. A timer removes that decision.
  • 25 minutes isn’t magic. No study shows it beats other lengths. Biwer’s study also tested 12-minute blocks, and the benefits it reported were for fixed breaks in general, not for one particular length.
  • Hard work needs real breaks. For demanding tasks, 5 minutes may not be enough. Use the long break, or try 50 minutes on and 10 off.
  • Don’t expect a productivity miracle. In both studies, total output was about the same. The gain was in how people felt while doing it.

Try it this way: run the classic 25 and 5 for a week. If the timer keeps cutting you off in the middle of deep work, make the blocks longer, but keep the breaks planned. That seems to be the part that matters.

A Pomodoro timer you can watch

Timefall’s Pomodoro mode splits your time into focus, short break and long break. Time falls as particles, so you can see how much is left at a glance, and Live Activities keep it on your Lock Screen.
