NYT: The summer vacation is more than a quaint tradition. If you’re feeling overwhelmed, there’s a reason: The processing capacity of the conscious mind is limited. Every status update you read on Facebook, every tweet or text message you get from a friend, is competing for resources in your brain with important things.

Taking breaks is biologically restorative. Naps are even better. In several studies, a nap of even 10 minutes improved cognitive function and vigor, and decreased sleepiness and fatigue. If we can train ourselves to take regular vacations — true vacations without work — and to set aside time for naps and contemplation, we will be in a more powerful position to start solving some of the world’s big problems. And to be happier and well rested while we’re doing it.
