Why is taking a short, planned break during work useful?

Correct answer: To reduce fatigue and restore focus

A brief, planned break gives the mind and body an opportunity to recover from continuous effort. Returning after a suitable break can improve attention and reduce careless errors, especially during long tasks. It should be part of a sensible schedule, not a way to avoid responsibility or postpone work indefinitely. Thus, reducing fatigue and restoring focus is the best answer.
