But what do you *do* during those mini-breaks? I'm speaking from experience and intuition here, without data to back me up, but I doubt you would find yourself any more prepared to tackle the task if you were switching to another of similar importance & difficulty, as opposed to doing something relaxing. I find there is a big difference between a conscious decision to take a break from doing something, and having things intrude on your time and attention in an uncontrolled manner.
Concentrating on something for a long time, taking a break, then coming back to it is not the same thing as trying to concentrate on multiple things at once, or having a constant stream of distractions.
