Feeling drowsy? A new study suggests most Americans aren't getting enough sleep.
Researchers at Ball State University say about 36 percent of working adults get less than seven hours of sleep per night - up more than five percent since 2010.
Even more alarming? Those numbers increase to 50 percent for police officers and health care workers - people responsible for saving lives.
- Researchers say sleep deprivation has been going up since the mid-80's and blame stress as the biggest factor.
