Friday marks World Sleep Day

In honor of World Sleep Day, here are a few fun facts about who gets the most Zs. A study by the Centers for Disease Control show about one-third of Americans sleep less than seven hours a night. On the other hand, about the same amount say they got enough sleep "every day" last month.

Where you live seems to matter.

More than 19 percent of West Virginians report frequent trouble sleeping. People in North Dakota have the least amount of trouble getting a good rest -- just under 7.5 percent.

If you think Americans in general sleep less than others around the world, you're wrong. Although the French sleep the most -- about nine hours a day -- America comes in second, at about eight and a half. South Koreans get the least sleep.

Also, in the United States, women are more likely to report sleep problems than men, along with people between the ages of 25-34. And the higher your level the education, the less likely you are to get a good night's rest.


According to several studies, we have about five dreams a night but remember very few of them.

The most common subjects in dreams include falling, being chased, teeth falling out, being back in school and a spouse cheating on you.

There are many different interpretations of what these dreams mean. But of course most focus on stress, poor communication and other daytime pressures that come to life in such bizarre ways at night.
