Insomnia

Insomnia can cause problems during the day, such as excessive sleepiness, fatigue, trouble thinking clearly or staying focused, or feeling depressed or irritable. It is not defined by the number of hours you sleep every night. Although the amount of sleep a person needs varies, most people need between 7 and 8 hours of sleep a night.

What is Insomnia?

Insomnia is a condition in which it is difficult to get to sleep, or to remain soundly asleep, resulting in too short and too low-quality sleep which affects normal functioning. It causes fatigue and daytime sleepiness. It may be classified as acute, lasting a few days or weeks, or chronic, when it lasts longer than a month.
