Insomnia Overview

Most adults have experienced insomnia or sleeplessness at one time or another in their lives. An estimated 30%-50% of the general population are affected by insomnia, and 10% have chronic insomnia.

Insomnia is a symptom, not a stand-alone diagnosis or a disease. By definition, insomnia is "difficulty initiating or maintaining sleep, or both" or the perception of poor quality sleep. Insomnia may therefore be due to inadequate quality or quantity of sleep. Insomnia is not defined by a specific number of hours of sleep that one gets, since individuals vary widely
