WORKING OUT—WHETHER YOU’RE sweating under some iron, going for a quick run, or busting out a quick 20 pushups—is often a good way to clear your head. In a sense, your old high school gym coach’s “get your blood pumping” tactic really can help you get some perspective on a problem or issue with which you’ve been dealing.

In fact, you don’t even need to get your blood pumping that hard. Just a 10-minute session of aerobic exercise can give your brain a jolt, boosting your decision-making process and improving your focus, according to a new study published in Neuropsychologia.
