New research shows that 'super sleepers' may be more tired than they think

NEW YORK (WABC) -- Have you ever envied people who say they can sleep for just a few hours a night and still feel fresh the next day?

According to new research, they may actually be more drowsy than they feel.

Researchers at the University of Utah ran a sleep study where they split participants into two groups: those who said they were drowsy and those who said they weren't.

The participants were given fMRI brain scans and found that those who claimed not to feel drowsy did show signs of drowsiness and increased connectivity in other parts of the brain.

These results suggest that external stimuli can make people think they are more awake than they actually are.
