Insomnia is the No. 1 health-related problem in the U.S. More than one-third of the adult population has problems falling asleep or with daytime sleepiness.
Despite all the Internet advice and the prevalence of CPAP machines, the problem is getting worse, not better. The number of adults ages 20-44 using sleeping pills doubled between 2000 and 2004, and reached 56 million in 2008. The number of youth ages 1-19 who take prescription sleep remedies jumped 85 percent during the same period.
