(CNN) - Americans simply don't get enough sleep. Missing out on your zzzz's can take a toll on your productivity and your health.
"You need more sleep." You've heard your mother say that, and many folks have listened, but according to a new survey, Americans, even really sleepy ones, aren't doing anything about it.
Well wake up and smell some facts. The centers for disease control has called not getting enough sleep a " Public Health Epidemic."
Why? Because those who don't sleep enough are more likely to be depressed, overweight, less productive, and many simply don't look as good as when they're sleeping enough. Don't you want to be beautiful?
The better sleep council reports that nearly half the people in America say they don't get enough sleep, but fewer than half of them take specific action to catch some zzzz's. That could be because many simply don't believe a lack of sleep is bad for you.
45% of guys, for instance, say that people can learn to live with less sleep. The council, a non-profit group supported by the mattress industry, calls that a myth. 80% of Americans say they get stressed or have trouble concentrating when they're sleepy. But fewer than 30% of them believe a lack of sleep can contribute to memory problems, heart problems, or diabetes. It can.
So how much sleep do we need? For kids, it's 10 to 11 hours a night. Teenagers should aim for 8-and-a-half hours or more. And adults: 7 to 9 hours a night.
If you're not serious about getting enough sleep, the council is hoping this will be a wake-up call.
