Stand up stretch, do some cross crawls (particularly helpful if you are getting bogged down.) Cut up an apple to chew while studying (chewing brings oxygen to the brain and helps the learning process) Or unwrap sugar free gum. Refill your water glass. Pat the cat, take a fluid adjustment break, toss the ball for the dog, get the meat out of the freezer for dinner, get your mail from the letter box (sort through it the next break).
Anything that just gets you out of the seat for a few minutes is enough, the 5 minute break doesn't need to be a full 5 minutes and surprisingly enough most of the examples will take at least 2 or 3 minutes. When you sit down again and review you might still be on the break however you've changed your state. Taken time to check that you are still on track to your goal / desired outcome.
