Insomnia is the most common sleep complaint. It occurs when you have trouble falling asleep or staying asleep even though you had the opportunity to get a full night of sleep. The causes, symptoms and severity of insomnia vary from person to person. Insomnia may include:
Difficulty falling asleep
Difficulty staying asleep throughout the night
Waking up too early in the morning
Insomnia involves both a sleep disturbance and daytime symptoms. The effects of insomnia can impact nearly every aspect of your life. Studies show that insomnia negatively affects work performance, impairs decision-making and can damage relationships. In most cases, people with insomnia report a worse overall quality of life.
