READING TIME: 1 MINUTE
Insomnia, which is Latin for “no sleep,” is the inability to fall asleep or stay asleep. Insomnia is also used to describe the condition of waking up not feeling restored or refreshed.
Insomnia is the most common sleep complaint among Americans. It can be either acute, lasting one to several nights, or chronic, even lasting months to years. When insomnia persists for longer than a month, it is considered chronic. According to the National Center for Sleep Disorders Research at the National Institutes of Health, about 30-40 percent of adults say they have some symptoms of insomnia within a given year, and about 10-15 percent of adults say they have chronic insomnia. More often, people experience chronic-intermittent insomnia, which means difficulty sleeping for a few nights, followed by a few nights of adequate sleep before the problem returns.
Insomnia can be a disorder in its own right, but often it is a symptom of some other disease or condition. In the case of stress-induced insomnia, the degree to which sleep is disturbed depends on the severity and duration of the stressful situation. Sometimes this may be a disturbing occurrence like loss of a loved one, loss of a job, marital or relationship discord or a tragic occurrence. Anticipation of such things as weddings, vacations, or holidays can also disturb sleep and make it difficult to fall asleep or remain asleep. Insomnia can also occur with jet lag, shift work and other major schedule changes.
