Sleep is vital to our health and well being. Yet millions of us are not getting enough sleep, or are suffering from other sleep problems. For example, surveys conducted by the National Sleep Foundation reveal that 60 percent of adults report having sleep problems a few nights a week or more. In addition, more than 40 percent of adults experience daytime sleepiness severe enough to interfere with their daily activities at least a few days each month - with 20 percent reporting problem sleepiness a few days a week or more.

At least 40 million Americans suffer from sleep disorders, yet more than 60 percent of adults have never been asked about the quality of their sleep by a physician and fewer than 20 percent ever initiated a discussion.

Poor sleep has a price. Millions of individuals struggle to stay alert at home, in school, on the job - and on the road. Tragically, fatigue contributes to more than 100,000 police-reported highway crashes, causing 71,000 injuries and 1,500 deaths each year in the United States alone.
