Sleep
Sleep is upstream of almost everything. Here's what we know.
Reviewed by Shariq Refai, MD, MBA
Sleep sits underneath most mental health conditions. Anxiety disrupts it. Depression changes it. Bipolar episodes are sometimes triggered by it. This hub exists because sleep is often the most powerful variable in mental health treatment and deserves its own clinical landing page.
Sleep isn't a separate problem from mental health. It's part of the same system. When sleep breaks, anxiety gets louder, mood drops, attention scatters, and the threshold for everything else gets lower.
Sleep trouble also has its own diagnosable patterns: insomnia disorder, sleep apnea, circadian rhythm disorders, parasomnias. Many people have those AND a mental health condition, and treating either one alone usually doesn't work.
This hub maps the conditions, symptoms, and treatments where sleep is central. If sleep is what brought you here, start with the symptoms section.

Treatment Overview
The most effective treatment for chronic insomnia is cognitive behavioral therapy for insomnia (CBT-I), not medication. CBT-I produces sustained improvement that outlasts treatment, while sleep medications work only while you're taking them and often produce rebound insomnia when stopped. CBT-I includes stimulus control (reserving the bed for sleep), sleep restriction (matching time in bed to actual sleep time), and cognitive techniques. It can be delivered in person, via telehealth, or through validated self guided apps. When medication is needed short term, lower risk options are nonbenzodiazepine hypnotics (Z drugs like zolpidem and eszopiclone) for limited periods, dual orexin receptor antagonists (suvorexant, lemborexant, daridorexant) which have lower dependence risk, ramelteon, low dose doxepin, or trazodone. Benzodiazepines are usually avoided for chronic insomnia because of dependence risk and morning impairment. Sleep apnea, restless legs syndrome, and circadian rhythm disorders are distinct conditions that need their own evaluation; a sleep study is appropriate when sleep apnea is suspected. Treating co occurring anxiety, depression, or substance use often improves sleep substantially.
