What is the Pomodoro Technique?

A time-management method by Francesco Cirillo (1980s) that alternates 25 minutes of focused work with 5 minutes of rest. Every 4 cycles, take a longer 15–30 minute break. The rigid time-boxing helps sustain focus and reduces mental fatigue compared to marathon sessions.

Why 25 minutes specifically?

It's short enough to sustain full concentration without willpower fatigue, and long enough to make meaningful progress on a task. Research on sustained attention consistently shows focus breaks down past 30–45 minutes of continuous task demands — 25 minutes comfortably fits inside that window.

Should I adjust the timer length?

Yes, if 25/5 doesn't match how you work. Deep writing or coding may benefit from 50/10. Reading or rote study may do well at 20/5. The pattern matters more than the exact numbers — work, break, repeat.
