Is 25 minutes too short? The Pomodoro debate

Quick answer

A common complaint: you don't really get anything done in 25 minutes, and 5 minutes is too short for a real break. Many people switch to 50/10. Do they have a point?

What a study found

A 2023 study compared students taking a 6 minute break every 24 minutes, a 3 minute break every 12 minutes, or breaks whenever they chose. Those who chose their own breaks studied in longer stretches but reported more fatigue and distraction and less concentration and motivation. Task completion was about the same, and the fixed-break groups got there in less time (a 2023 study on study breaks).

Where the critics are right

Deep work like writing or coding takes time to warm up.
A timer that cuts you off mid-flow can be annoying.
Five minutes isn't always enough to reset.

What the study suggests

Fixed breaks seem to protect mood and focus, whatever the length.
Letting yourself 'just keep going' often leads to longer, more tired sessions.

Pick your length

Starting is hard: 15/5 or 25/5.
Deep work: 45/10 or 50/10.
Keep the break fixed, whatever block you choose.
