Does the Pomodoro Technique work? What three recent studies found

The Pomodoro Technique works about as well as taking breaks whenever you choose, according to three recent experiments with university students. None of them found a difference in how much people got done or learned. Fixed breaks left people feeling better in one study and worse in another, so the schedule that suits you is worth testing.

What is the Pomodoro Technique?

The Pomodoro Technique is a way of working in short, timed rounds. In the form researchers test, you work for 25 minutes, take a 5-minute break, and after four rounds take a longer break of 15 to 30 minutes.⁵

Francesco Cirillo created it. On his official site he writes that he made it “in the 1980s with a tomato-shaped kitchen timer and a problem: I couldn’t focus on my university studies.”¹ Pomodoro is Italian for tomato.

Cirillo also says the method is “much more than a sequence of 25-minute sessions.”¹ His full version also covers planning your work, estimating effort and recording what happens. The studies below tested only the timing part: fixed work rounds with fixed breaks.

What did the studies find?

Three experiments compared fixed breaks with breaks people chose themselves, and none found a difference in output. They differed on how people felt. All three come from researchers at Maastricht University in the Netherlands, all used university students studying online, and each lasted one session or one day.

2023: fixed breaks felt better. Biwer and colleagues followed students through a day of their own studying. One group took a 6-minute break after every 24 minutes, one took 3 minutes after every 12, and one decided for itself. The self-deciders studied in longer stretches and took longer breaks. They also reported more fatigue and distraction, and less concentration and motivation. Task completion and mental effort did not differ.²

2025: no overall difference. Smits and colleagues gave psychology students two hours with their own study tasks. One group worked 25 minutes and rested 5. One chose freely. A third used “Flowtime”: stop when you want, with a break that grows with how long you worked. Productivity, task completion and flow came out the same. Across the two hours, fatigue rose faster and motivation fell faster with 25/5, but the averages for the session did not differ.⁵

2026: self-chosen breaks felt better. Göksu and colleagues had students read a text and then take a comprehension test. About half worked 12 minutes and broke for 3. The rest took breaks when they wanted. Test scores did not differ significantly. The self-chosen group felt more energised, more concentrated and more motivated, felt less distracted, and liked their way of taking breaks more.³

Why would fixed breaks help, and why might they not?

Fixed breaks take one decision off your plate, and that is also their cost. The 2026 authors suggest that a set schedule may help by “reducing the need for students to continually monitor and decide when to pause during learning.”³ The 2023 study fits that idea: students who chose for themselves worked longer stretches and reported more fatigue.²

The cost is interruption. A timer stops you whether or not you are in the middle of a thought. In the 2026 study, many students in the 12-minute group said the rounds were too short and broke their focus. One wrote:

“I found it [systematic short break] too short, my concentrations were broken each time”

Others in the same group liked the structure. One said it helped because “I told myself I ‘only’ had to focus for 12 min before I could do something fun.”³ So the same fixed round helped some students keep going and broke the concentration of others.

How long should a focus block be?

No study has found one best length, so 25 minutes is a reasonable place to start. In 2023, both the 24-minute and the 12-minute schedules came out ahead of free breaks on mood, with the same task completion.² The 12-minute schedule felt too short to many students in 2026, and its authors suggest testing longer formats.³ With the classic 25/5 in 2025, fatigue climbed faster over two hours than with free breaks.⁵

A practical reading of all three: if the bell keeps cutting into good work, lengthen your rounds to 40 or 50 minutes. If you fade well before the bell, shorten them. Both are guesses to test, and neither is a research finding.

What does research on breaks in general say?

Short breaks give a small, real lift in how you feel, and their effect on output is less clear. A 2022 meta-analysis pooled 22 samples, both employees and students, in labs and workplaces. It looked at “micro-breaks” of 10 minutes or less, and its authors note that the number of studies for each outcome was modest.⁴

• Breaks raised vigour a little and lowered fatigue a little.
• Overall performance did not improve significantly. It did improve on less demanding tasks.
• Longer breaks went with bigger gains in performance. The authors suggest that after very demanding work, you may need more than 10 minutes.

How do you test fixed against flexible breaks?

Run a two-week experiment on yourself: one week of fixed breaks, one week of flexible ones, with the same kind of work in both. The studies measured output, tiredness and distraction, so you can track the same three things. A kitchen timer or a phone timer is enough.

1. Week 1, fixed. Work 25 minutes, break 5, and take a longer break after four rounds. Stop when the timer says so.
2. Week 2, flexible. Work until you notice yourself fading, then break for 5 to 10 minutes.
3. Each evening, fill in one row of the table below.
4. At the end, compare the two weeks. Keep the one with similar output and lower tiredness. If they tie, keep the one you liked.
