Sleep Facts & Stats - Insomnia and Treatments

A majority of American adults (63%) do not get the recommended eight hours of sleep needed for good health, safety, and optimum performance. In fact, nearly one-third (31%) report sleeping less than seven hours each week night, though many adults say they try to sleep more on weekends. (2001 Sleep in America poll).

More than half of adults surveyed in the 2002 Sleep in America poll said they experienced one or more symptoms of insomnia at least a few nights a week. Insomnia is characterized by difficulty initiating sleep, difficulty maintaining sleep, or waking too early.

Up to 40% of adults report at least occasional difficulty sleeping; chronic and/or severe insomnia affects about 10-15% of adults, according to the National Institutes of Health (NIH). Direct costs of insomnia, which include dollars spent on insomnia treatment, healthcare services, hospital and nursing home care, are estimated at nearly $14 billion annually. Indirect costs such as work loss, property damage from accidents and transportation to and from healthcare providers, are estimated to be $28 billion.

Sleep apnea, a breathing disorder characterized by brief interruptions of breathing during sleep, affects as many as 18 million people, according to NIH. Estimates indicate that untreated sleep apnea may cause $3.4 billion in additional medical costs (SLEEP, 1992).

Approximately 12 million Americans have restless legs syndrome, a sleep and movement disorder characterized by unpleasant (tingling, crawling, creeping and/or pulling) feelings in the legs, which cause an urge to move in order to relieve the symptoms.
