Insomnia, also known as sleeplessness, is a sleep disorder where people have difficulty sleeping.[1][11] They may have difficulty falling asleep, or staying asleep for as long as desired.[1][9][12] Insomnia is typically followed by daytime sleepiness, low energy, irritability, and a depressed mood.[1] It may result in an increased risk of accidents of all kinds as well as problems focusing and learning.[9] Insomnia can be short term, lasting for days or weeks, or long term, lasting more than a month.[1] The concept of the word insomnia has two distinct possibilities: insomnia disorder (ID) or insomnia symptoms, and many abstracts of randomized controlled trials and systematic reviews often underreport on which of these two possibilities the word refers to.[13]

Insomnia can occur independently or as a result of another problem.[2] Conditions that can result in insomnia include psychological stress, chronic pain, heart failure, hyperthyroidism, heartburn, restless leg syndrome, menopause, certain medications, and drugs such as caffeine, nicotine, and alcohol.[2][8] Insomnia is also common in people with ADHD,[14] and children with autism.[15] Other risk factors include working night shifts and sleep apnea.[9] Diagnosis is based on sleep habits and an examination to look for underlying causes.[3] A sleep study may be done to look for underlying sleep disorders.[3] Screening may be done with questions like "Do you experience difficulty sleeping?" or "Do you have difficulty falling or staying asleep?"[9]

Although their efficacy as first line treatments is not unequivocally established,[16] sleep hygiene and lifestyle changes are typically the first treatment for insomnia.[5][7] Sleep hygiene includes a consistent bedtime, a quiet and dark room, exposure to sunlight during the day and regular exercise.[7] Cognitive behavioral therapy may be added to this.[6][17] While sleeping pills may help, they are sometimes associated with injuries, dementia, and addiction.[5][6] These medications are not recommended for more than four or five weeks.[6] The effectiveness and safety of alternative medicine are unclear.[5][6]

Between 10% and 30% of adults have insomnia at any given point in time, and up to half of people have insomnia in a given year.[8][9][10] About 6% of people have insomnia that is not due to another problem and lasts for more than a month.[9] People over the age of 65 are affected more often than younger people.[7] Women are more often affected than men.[8] Descriptions of insomnia occur at least as far back as ancient Greece.[18]
