Insomnia: Causes, Consequences, and Treatment

Insomnia is the most common sleep disorder, affecting approximately one-third of adults with at least occasional symptoms and about ten percent with chronic insomnia disorder. It is characterized by difficulty falling asleep, staying asleep, or waking too early, resulting in inadequate or non-restorative sleep that impairs daytime functioning. Chronic insomnia has significant consequences for health, including increased risk of depression, cardiovascular disease, diabetes, impaired immune function, and cognitive decline. Insomnia commonly co-occurs with and is often perpetuated by other conditions including depression, anxiety, chronic pain, sleep apnea, restless legs syndrome, and numerous medical conditions. Medications including stimulants, beta-blockers, corticosteroids, and decongestants can disrupt sleep. Identifying and addressing contributing factors is an important part of insomnia management. Cognitive behavioral therapy for insomnia, known as CBT-I, is the most evidence-supported treatment and is recommended as first-line therapy ahead of medications. CBT-I addresses the thoughts and behaviors that perpetuate insomnia through components including sleep restriction therapy, stimulus control, relaxation techniques, sleep hygiene education, and cognitive restructuring of unhelpful beliefs about sleep. Research shows that CBT-I produces more durable improvement than sleep medications without risks of dependence. Digital and telehealth-delivered CBT-I programs have expanded access significantly.

Sleep hygiene practices support better sleep but are insufficient alone for chronic insomnia. Maintaining a consistent sleep schedule, keeping the bedroom cool, dark, and quiet, avoiding stimulating activities near bedtime, limiting caffeine and alcohol, and avoiding screens in the hour before sleep all contribute to better sleep opportunity. Medications for insomnia include both over-the-counter options such as diphenhydramine and prescription medications including benzodiazepines, Z-drugs, suvorexant, and low-dose doxepin. Medications are generally recommended for short-term use or as a bridge while initiating CBT-I.
