About Insomnia

Insomnia is a serious worldwide condition that affects a large number of individuals. According to the National Sleep Foundation's Sleep in America Poll 2005, approximately 50 percent of the U.S. adult population reported experiencing at least one symptom of insomnia for several nights a week during the last year. This represents more than 100 million Americans, a figure supported by several reviews in Sleep Medicine. An estimated 30 percent to 40 percent of all adults complain of transient insomnia, generally defined as a complaint lasting up to three weeks, while 10 percent to 15 percent complain of chronic insomnia, generally defined as a complaint lasting approximately four weeks or longer. In addition, sleep maintenance insomnia, or the inability to stay asleep throughout the night, is significantly more prevalent than sleep onset insomnia.
