Insomnia is a sleep disorder defined by persistent difficulty falling asleep, staying asleep, or waking too early, along with daytime impairment (fatigue, mood changes, reduced concentration). Insomnia can be short-term (acute) or long-term (chronic), and it can significantly affect quality of life, safety, and performance at work or school.
