Background
What is the Pomodoro Technique?
The Pomodoro Technique is a time management method of alternating focused work intervals with short breaks, developed by Francesco Cirillo in the 1980s. Typically, one set consists of 25 minutes of work and 5 minutes of rest, with a longer 15-30 minute break after every 4 sets.
Why 25 minutes work and 5 minutes break?
25 minutes is a widely used benchmark that balances staying focused before concentration drops with allowing enough time to complete meaningful work. Longer breaks between sets address fatigue that short breaks alone cannot relieve. Time intervals can be adjusted based on the nature of your work.
