Sleep and Depression
Most people experience mild irritability or mood changes when they have insomnia, but sleep deprivation can have an even greater impact on those with mood disorders.
Chronic sleep deprivation and irregular sleep habits not only worsen depression but may also interfere with its treatment. Sleep disturbances can even trigger a manic episode in some people.
Focusing on getting regular, adequate sleep is a crucial part of controlling symptoms and increasing the benefits of other mood disorder treatments. (In some depressed people, controlled sleep deprivation may result in very brief, temporary improvements in depressive symptoms.)
