What is Insomnia?
Insomnia is a serious sleep disorder. It can mean the inability to fall asleep or stay asleep throughout the night, or the tendency to wake too early before having gotten enough sleep. Insomnia is often used to describe the condition of waking up not feeling well-rested or restored, and is the most common reported sleep disorder among Americans. According to the National Sleep Foundation, between 30 and 40 percent of adults say they experience some symptoms of insomnia within a given year, and a recent study by the Centers for Disease Control and Prevention found the majority of Americans experience difficulty sleeping at least once a month.
