Healthy sleep helps to regulate your mood and emotional health. Sleep problems often occur together with mood disorders such as depression. Anxiety disorders also can involve sleep problems. Sleeping at least 7 hours nightly and getting help for a sleep problem can improve your mood and emotional health.


  • Adults should sleep 7 or more hours per night on a regular basis to promote optimal health.
  • Insomnia often occurs along with depression and anxiety.
  • Untreated sleep disorders such as obstructive sleep apnea can impair your mood.
  • Cognitive behavioral therapy and other treatments can improve both your sleep and mood.

Am I At Risk:

Adults who sleep less than 7 hours nightly have a higher risk of mood problems. Sleep disorders that disrupt your sleep also can have a negative impact on your mood. Insomnia, depression and anxiety share many common risk factors. These include:

  • Traumatic or stressful events
  • Major life changes
  • Medical problems, such as cancer or chronic pain
  • Side-effects of certain medications
  • Drug or alcohol use


Sleep is important for your mood and emotional health. Sleeping less than 7 hours nightly increases your risk of depression and other mood disorders. Depression involves a sad mood that interferes with your daily functioning. Ongoing sleep loss also increases your risk of having suicidal thoughts. Anxiety involves worries or fears that have a negative impact on your daily life. Insomnia can cause depression and anxiety, and depression and anxiety can cause insomnia.

By disrupting your sleep, an untreated sleep disorder also can disturb your mood. Common sleep disorders that can increase your risk of depression include obstructive sleep apnea and shift work disorder. People with restless legs syndrome have a higher risk of depression and anxiety. Nightmares, insomnia, depression and anxiety are all common in people who have post-traumatic stress disorder (PTSD).


Cognitive behavioral therapy for insomnia (CBT-I) is the most effective, long-term treatment for chronic insomnia. CBT-I teaches you to change negative thoughts and attitudes about sleep. You also develop relaxation skills and learn how to change behaviors that interfere with sleep. By reducing insomnia symptoms, CBT-I also can improve your mood.

Sleeping pills are a short-term treatment option for insomnia. Like all medications, these drugs can cause a variety of side-effects. You should take a sleeping pill only when supervised by a doctor. Some pills are used to treat both insomnia and either depression or anxiety.

Treating insomnia, depression or anxiety also may involve treating an underlying medical problem, such as chronic pain. Changing medications also may improve your sleep and mood.

Bright light therapy is a treatment option for some circadian rhythm sleep-wake disorders. Light therapy also can provide a boost to your mood.
