What is the relationship between sleep disturbance and mental health symptoms?

• A. Sleep disturbances can worsen mood and anxiety and are often a symptom or a precipitating factor in mental illness
• B. Sleep has no impact on mental health
• C. Sleep disturbances solely cause psychosis
• D. Sleep improves mental health

Answer: (A)

Sleep problems and mental health influence each other in a two-way way. When sleep is disturbed, mood tends to worsen, anxiety can increase, and thinking and impulsivity can suffer. This makes sleep disturbances either a symptom of a mental illness or a factor that can precipitate or aggravate it. At the same time, many psychiatric conditions disrupt sleep through ongoing worry, mania, mood dysregulation, or effects of medications. Because of this bidirectional link, addressing sleep problems is often a key part of improving overall mental health. Sleep loss can also act as a trigger for symptoms in vulnerable individuals, especially in mood disorders, but sleep disturbances do not by themselves cause all cases of psychosis or other mental illnesses. And while good sleep supports well-being, it is not a universal cure for mental health conditions.
