Read something, an article or a book which is more short snippets (try Marcus Aurelius' Meditations, those five minutes will change your life). I have a list with a whole bunch of tech topics that I could read a quick MDN/wikipedia/whatever article on. If its a quick game, Call of Duty or some racing game where a race only takes a few minutes. I actually find taking a break and then gaming for five/ten minutes to be really good for my attention since it really forces me to focus completely for that time. Otherwise, just stand outside with your coffee and breathe.
