Insomnia is usually a transient or short-term condition. In some cases, however, insomnia can become chronic.

Acute insomnia lasts up to 1 month. It is often referred to as adjustment insomnia because it most often occurs in the context of an acute situational stress, such as a new job or an upcoming deadline or examination. This insomnia typically resolves when the stressor is no longer present or the individual adapts to the stressor.

However, transient insomnia often recurs when new or similar stresses arise in the patient’s life. [7] Transient insomnia lasts for less than 1 week and can be caused by another disorder, changes in the sleep environment, stress, or severe depression.
