Anxiety is an understandable response to perceived threat or experienced stress, and is usually fleeting and feels controllable: it represents an ‘alarm’, facilitating physical and psychological responses to perceived danger. Anxiety symptoms are mostly mild and transient, but many people experience severe and persistent symptoms that cause distress and impair everyday function. An anxiety disorder can be diagnosed when distressing and impairing anxiety exceeds specified severity thresholds and persists beyond minimum duration requirements, providing symptoms are not explicable by another condition. Insomnia is a common disorder in which sleep is reduced in amount or quality so that daytime well-being and functioning is impaired.
