Definition
Acute insomnia lasts for less than three months and is often related in time to an identifiable cause. Insomnia is present when there is difficulty initiating or maintaining sleep or when the sleep that is obtained is non-refreshing or of poor quality. It may be associated with early morning awakenings. These problems occur despite adequate opportunity and circumstances for sleep and they must result in problems with daytime function. Other sleep problems of this duration include circadian rhythm sleep disorders such as jet lag and potentially shift work, as well as high altitude insomnia.
Synonyms

Symptoms
There are many common symptoms of acute insomnia, including:
Difficulty falling asleep Difficulty staying asleep Early morning awakenings Fatigue or daytime sleepiness Poor attention or concentration Mood changes (including worry or reduced motivation or energy) Social or vocational dysfunction (including increased errors or accidents) Tension, headache, or stomach symptoms
Causes
There are many potential causes of acute insomnia, ranging from physical to psychological to social to environmental. In most cases, the condition resolves when the affected person adapts or no longer is subject to the cause. These potential causes include:
Changes in noise, lighting, temperature, or other conditions of the sleep environment Medications (especially those with stimulant properties) Use of caffeine or nicotine or withdrawal from alcohol or sedating medications Pain Stress (varying from routine stressors to job loss, grief reactions, and divorce) Nocturia (nighttime urination)
Diagnosis
Insomnia does not require any special testing in order for a diagnosis to be established. In fact, a diagnosis can be made by a healthcare provider who performs a careful history and physical examination. It is important that coexisting medical condition, psychiatric and neurologic disorders, sleep disorders, and medication or drug causes be considered. Sleep apnea and restless legs syndrome are the most common triggers of secondary insomnia. In some cases, additional testing may be indicated, though this is not often the case.
Treatments
If insomnia lasts more than three months, it may be labeled as chronic insomnia. When this occurs, it may be necessary to pursue treatment with sleeping pills or cognitive behavioral therapy for insomnia (CBTI).
A Word From Verywell
It is incredibly frustrating to experience insomnia. Fortunately, simple changes may be hugely beneficial. If you are struggling to fall asleep one night, get up after 20 minutes. Find a quiet place to relax. Read, listen to music, or watch a familiar movie or television show. Once you start to feel drowsy, return to bed. Repeat this as often as is necessary. This can be a helpful way to reset a bad night of sleep. If you have persisting difficulties, consider speaking with a board-certified sleep specialist. Our Doctor Discussion Guide below can help you start that conversation with your healthcare provider.
