Are Americans sleeping less at nights and drinking more caffeine during the day to rouse themselves to do the day's work, feeling drowsy and tired all the while?
The Center for Disease Control (CDC) has released the findings of a new study that indicates adults in America are not getting enough rest each night.
Of the adults interviewed for the study in Delaware, Hawaii, New York and Rhode Island, 70% said they did not get enough sleep or rest every day in the past month.
Younger adults slept less than the older ones, according to the study. Of those adults aged between 18 and 34, 13.3 percent lacked enough sleep every day, compared to 7.3 percent of adults over 55 who slept less.
The National Sleep Foundation prescribes 7-9 hours of sleep for adults each night for healthy living. The study shows that many adults are not getting that.
A National Health Interview Study shows that the number of adults sleeping an average of 6 hours or less in America, irrespective of their age group, has jumped from 20% to 30% from 1985 to 2006.
The CDC says that an estimated 50-70 million people suffer from sleep loss or sleep disorders. Most people surveyed did not realize that less sleep could affect their health.
The study also found that retirement improved people's sleeping time and adults in Hawaii got more sleep than their counterparts in the other three states that the study covered.
