Here's How Many Americans Actually Sleep 7 Hours

The Centers for Disease Control and Prevention, which conducted the study, recommends that adults ages 18 to 60 get at least 7 hours of sleep per night. Too little sleep increases the risk for a number of health conditions, including obesity, diabetes, high blood pressure, heart disease, stroke and frequent mental distress, the CDC said. The new findings suggest "an ongoing need for public awareness and public education about sleep health," the report said.
