@Gimmick @Bonnot More specifically, our brains continue working "in the background" even when we stop a task; it's why people suggest going outside for a walk or something when you're unable to progress in a particular task - because by "going for a walk" you're giving your brain time to consolidate, reorganize and work out what it's dealt with so far.
Basically, taking a break is like defragmenting your brain.

sometimes the best course of action is to take a break. Brains are funny like that.
