You know you should be getting 7-9 hours of sleep every day -- but who says it has to happen during one marathon snoozing session?
David K. Randall, author of Dreamland: Adventures in the Strange Science of Sleep, points to a growing body of evidence suggesting that getting enough "deep" sleep during the course of the day -- rather than in one eight-hour chunk -- might be just as beneficial from a performance point of view. For example, taking a "power nap" at work (if it's OK with your boss!) might be just as restorative as sleeping peacefully all night long.
Do you ever break up your sleep into smaller chunks? Or do you need 7-9 consecutive hours to feel like a human being in the morning (as opposed to a cranky $#^$%)?
