Sleep Disorders and Anxiety

Anxiety can cause, or be a symptom of, many sleep disorders. Commonly seen sleep disorders include:


  • insomnia
  • REM behavior disorder, including panic attacks and sleep paralysis

Insomnia is the most universal, and while anxiety is known to induce insomnia, insomnia can also cause or worsen anxiety. Many people with anxiety find themselves awake at night due to fear, worry, obsessive thoughts, nightmares or gastrointestinal problems.

Some antidepressants prescribed for anxiety can also worsen sleep disorders.
