Sleep and mood affect each other in every way; poor or inadequate sleep can cause irritability and stress, while healthy sleep can help our well-being.
Chronic insomnia may increase the risk of developing a mood disorder, such as anxiety or depression.
Poor sleep and feelings of depression or anxiety can be helped through a variety of treatments, starting with improved sleep habits, and, if needed, extending to behavioral interventions and an assessment for a sleep or mood disorder.
