The truth about people who brag they don't need much sleep
For most of us, skimping on sleep means feeling cranky and foggyheaded the next day, but we all have that one friend who claims she can survive—even thrive!—on just a few hours a night.

Now, a new study suggests that people like that may indeed function better on less sleep—but they also may be more tired than they realize. In fact, they may be falling asleep throughout the day without even knowing it.

The research, conducted by University of Utah psychologists, radiologists, and neurologists, looked at MRI scans of about 900 people. The participants were split into two groups: those who reported getting a normal amount of sleep in the last month, and those who got six hours or less a night. People in the short-sleep group were then divided further, based on whether they reported daytime dysfunction—such as feeling too drowsy to perform common tasks—or said they generally felt fine.
