Adjustment insomnia is also known as transient, short-term, or acute insomnia. Causes can be divided into 2 broad categories: environmental and stress-related. Environmental etiologies include unfamiliarity, excessive noise or light, extremes of temperature, or an uncomfortable bed or mattress. Stress-related etiologies primarily involve life events, such as a new job or school, deadlines or examinations, or deaths of relatives and close friends.

Adjustment insomnia typically lasts 3 months or less. The insomnia resolves when the stressor is no longer present or the individual adapts to the stressor.
