Americans Need More Sleep

Most of Americans sleep less than recommended by experts.
The Center for Disease Control surveyed 19589 adults in the states of Delaware, Hawaii, New York and Rhode Island. They were questioned about how many days within the past month they slept less than needed. The survey found that 70% of questioned adults lack daily sleep. 10% reported lack of sleep for every single day of the past month. 38% reported lack of sleep for 7 days of the past month.
13.3% of questioned younger adults aged from 18 to 34 reported lack of sleep, compared to 7.3% adults of age of 55 and older. Surveyed adults from Hawaii appeared to have less sleepless nights, compared to the rest of surveyed people. However, the survey didn't ask how many hours a day adults sleep.
CDC also examined data during the period from 1985 to 2006 about how many hours adults lack in sleep. Data showed that Americans lacking sleep increased during this period from 1985's 20% to 2006's 30%. These adults were having an average of 6 hours or even less daily sleep.
The survey showed no difference in sleep graphic between genders and different racial groups. All of them suffer from sleep disorders equally. However, those who have retired or are not able to work because of health conditions have better sleeping habits. Most of them reported to sleep normally every night.
National Sleep Foundation recommends from 7 to 9 hours of daily sleep for adults, from 8.5 to 9.5 hours for those aged from 11 to 17, and from 9 to 11 hours for those aged from 5 to 12.
Experts worn that sleep disorders may lead to 'obesity, diabetes, high blood pressure, stroke, cardiovascular disease, depression, cigarette smoking, excessive drinking.'
Experts urge everyone to sleep the recommended hours daily, because sleep is an important factor affecting health. Everyone must consider healthy sleeping as an important part of healthy lifestyle.
