How Much Sleep Is Needed?
The amount of sleep an individual gets can affect work performance, daily activities, mood and outlook on life in general.
In the survey, nearly 40% of adults report experiencing sleepiness to such a degree that it interferes with their daily activities at least a few days a month. Moreover, more than 1 in 5, or 22%, experience this level of daytime sleepiness on a weekly basis.
Alarmingly, more than half (53%) of adults in the U.S. report driving while drowsy in the past year, and nearly 20% have actually dozed off while driving. One in 100 claims to have had an accident while driving because tiredness or dozing off. Many catastrophic events have been attributed to falling asleep or inattentiveness due to sleepiness, including the Chernobyl nuclear disaster and the Exxon Valdez accident. This doesn't include the less publicized, but equally as devastating, motor vehicle accidents attributed to falling asleep while driving that claim the lives of thousands of people each year.
