The Pomodoro technique is a timebox mechanism, so it has benefits beyond triggering the state of relaxed focus. The sudden-death nature of a microtimebox like 25/5 and 48/12 is what forces you to eliminate the unnecessary. A person can stay in the flow and do lots of unimportant things beautifully. A timebox often means you make choices and then you keep going, staying in the present. Second-guessing is another form of distraction, as much as falling under Sunk Cost Fallacy. Another important note: it isn't so much that you avoid distractions as much as you stay in the present moment. Hindsight and foresight may guide your actions, however, you can only act in the present moment.
