Focus Duur Calculator

The Pomodoro Technique uses 25-minute work blocks followed by 5-minute breaks. After four blocks, you take a longer 15-30 minute break. It was developed by Francesco Cirillo in the late 1980s and remains popular for its simplicity.

Most people can sustain deep focus for 25-90 minutes before needing a break. The Draugiem Group study found 52 minutes work + 17 minutes rest was highly productive, while ultradian rhythm research points to 90-minute cycles.

Each time you switch tasks, your brain needs 15-25 minutes to fully re-engage. Frequent context switching can reduce productive time by up to 40%. Matching your work blocks to your natural focus span means fewer forced switches.

Start with blocks that match your current attention span, then increase by 5 minutes per week. Remove distractions before starting. Regular exercise, quality sleep, and hydration all improve baseline focus capacity.
