“The Sleepless Elite”

Are you a short sleeper? The Wall Street Journal says that’s an actual medical condition affecting one to three percent of the population. “Night owls and early birds simultaneously,” short sleepers only need five or six hours of sleep a night and are described as “unusually energetic and outgoing.” Researchers think the condition might be a mild form of mania.  Not a lot is known about short sleepers—they often don’t sign up for sleep studies or seek medical attention because they don’t think they have a problem—but a fairly recent study pinpointed a gene variation that, when replicated in a group of mice, produced several short sleepers.
