During 5-minute short breaks: Step away from your computer, stretch your body (especially neck, shoulders, and back), walk around, get a drink of water, do deep breathing exercises, or look out a window to rest your eyes. Avoid checking email, social media, or news - these don't give your brain true rest and can derail your momentum. During 15-30 minute long breaks: Take a real mental break - go for a short walk, have a snack, chat with someone, do light exercise, meditate, or engage in a hobby. The goal is to give your prefrontal cortex (the thinking part of your brain) a rest so it can recharge for the next session. Research shows that proper breaks improve subsequent performance and prevent decision fatigue. Don't skip breaks to "get more done" - this leads to burnout and reduced quality of work.
