Many of us know what it's like to feel deprived on a good night's rest, but did you know that 1% to 3% of the population can actually live happily with just a few hours of sleep per night?


What other superhuman qualities do these members of 'The Sleepless Elite' have? According to researchers, they don't need caffeine, and are energetic and upbeat despite having only a few hours of sleep. They tend to be thin, thanks to a fast metabolism, and they have a high tolerance for physical and psychological pain!

However, before you decide that you want to be a member of the sleepless elite, psychiatrists give this warning:
Out of every 100 people who believe they only need five or six hours of sleep a night, only about five people really do, Dr. Buysse says. The rest end up chronically sleep deprived, part of the one-third of U.S. adults who get less than the recommended seven hours of sleep per night, according to a report last month by the Centers for Disease Control and Prevention.

To date, only a handful of small studies have looked at short sleepers—in part because they're hard to find. They rarely go to sleep clinics and don't think they have a disorder.
