⏱
The Pomodoro Cycle
Work 25 min → short break 5 min → repeat × 4 → long break 15 min. After 4 focus blocks, you earn a proper 15-min break. The cycle then restarts.
🔔
Silent Office Mode
Enable browser notifications once — Chrome shows a pop-up in the bottom right corner when time's up, no tab switch needed. Uncheck the sound box for completely silent operation.

Why 25-Minute Blocks
Research on cognitive load (Cirillo, 1992) shows the brain sustains peak attention for 20–30 minutes. Forced micro-breaks prevent decision fatigue that compounds across the day.

What to Do on Breaks
Stand up, refill water, look at something >6m away (20-20-20 eye rule), or do 5 shoulder rolls. Don't scroll your phone — that's not a cognitive break, it's a context switch.

The NHS recommends breaking up sitting every 30 minutes. Prolonged sitting is linked to lower back pain, reduced circulation, and long-term metabolic risk. Standing up is non-negotiable.
