Is caffeine is a staple in your diet?  Do you find yourself dragging during the day?

According to a new study released by the Center for Disease Control (CDC), you may not be getting enough sleep, and you’re not the only one.

The study, which surveyed adults in Delaware, Hawaii, New York and Rhode Island, found that adults are not getting enough rest each night. And of those questioned, 70 percent said they had not gotten enough rest or sleep every day of the past month.

The study also discovered that a lack of sleep is a particular problem for younger adults. Of those between 18 and 34, 13.3 percent lacked enough sleep every day, compared to 7.3 percent of adults over 55. The study did not find much difference between races or genders.

The National Sleep Foundation says that most adults need 7-9 hours of sleep each night, but many are not getting that. 

According to a National Health Interview Study, adults nationwide averaged six hours or less of sleep a night increased in all age in groups from 1985 to 2006.  For example, in 1985, about 20 percent of men and women ages 45-64 reported sleeping an average of six hours or less. By 2006 that number had jumped to 30 percent.

The CDC also says an estimated 50-70 million people suffer from constant sleep loss or sleep disorders.

There is some good news. The CDC found that individuals who were retired or no longer working were twice as likely to report they got a full night.  Those who are unable to work at all, perhaps because of medical or mental issues, were the most likely to indicate 30 days of inadequate rest.

The study found those who lived in Hawaii apparently got more sleep than their counterparts in the other three states studied. Lifestyle choices, such as late-night television watching, Internet use, or caffeine and other stimulant intake, can also affect sleep patterns, the study said.
