Insomnia, depression and anxiety: what to know

Anxiety may keep your body and thoughts alert at bedtime. Depression may bring early waking, sleeping too much, low motivation or loss of interest, and insomnia can add irritability and fatigue. These symptoms can overlap without proving which condition came first. Changes in appetite, energy, enjoyment, concentration and sleep are useful details for assessment.

Notice the pattern across days rather than judging yourself after one poor night. A clinician can consider mental health, physical illness, substances, medicines and other sleep conditions together.

Keep a steady wake time, seek daylight early in the day and use a calm pre-sleep routine. Write worries down before bed, then choose a simple morning task to protect activity and structure. Avoid using alcohol or non-prescribed medicines to force sleep. Record mood, anxiety, sleep, energy and daytime functioning to share at an appointment.

Treatment may involve talking therapy, cognitive behavioural methods for insomnia, treatment for depression or anxiety, or a combination. Do not stop or change prescribed medicine without guidance, because some medicines affect sleep and need a planned review.

Arrange prompt medical support if low mood, anxiety or insomnia persists, limits daily activities, or causes unsafe sleepiness. Seek urgent help for thoughts of self-harm, a plan to harm yourself, feeling unable to stay safe, severe confusion or extreme agitation. Tell someone you trust while arranging help.

Could depression or anxiety be contributing to my sleep? Which treatment should we address first? Could my medicines or physical health affect the pattern? What support is available if my safety changes?
