Trying to focus for four hours straight without a break is like trying to sprint a marathon. Your brain loses sharpness after 30 minutes of intense concentration, leading to distraction and slow execution.
The Mechanics of 25-Minute Sprints
Set a timer for 25 minutes. Work on one single task with zero tab-switching. When the timer rings, step away from your desk for 5 minutes. Walk, stretch, or drink water. Repeat four times, then take a longer 20-minute break.
Why Short Breaks Reset Focus
Short breaks clear working memory and prevent decision fatigue. When you return to your desk, your mind feels fresh and ready for the next interval.
