People with insomnia usually experience one or more of the following symptoms: fatigue, energy deficiency, difficulty concentrating, mood swings, and reduced performance at work or at school.

Insomnia can be characterized by its duration of acute and chronic.

Bitter insomnia is short and is often a consequence of some life circumstances (for example, when you can not fall asleep before the exam, under stress or bad news). Many people may have experienced this type of insomnia, which normalizes itself without treatment.

Chronic insomnia is a disturbed sleep that occurs at least three nights a week and lasts for at least three months. Chronic insomnia can be caused by various factors. Changes in the environment, unhealthy sleep patterns, shift work. Clinical diseases and some drugs can lead to a long-term pattern of inadequate sleep.
