Insomnia
Insomnia includes having trouble falling or staying asleep. It's one of the most common medical complaints. With insomnia, you usually awaken feeling unrefreshed, which takes a toll on your ability to function during the day. Insomnia can sap not only your energy level and mood, but also your health, work performance and quality of life.
How much sleep is enough varies from person to person. Most adults need seven to eight hours a night. More than one-third of adults have insomnia at some time, while 10 to 15 percent report long-term (chronic) insomnia.
