What is insomnia?
Key points
Insomnia is difficulty initiating or maintaining sleep, or poor sleep quality, despite opportunity to sleep, with daytime impact such as fatigue, irritability, or reduced concentration.
Acute insomnia may follow stress, travel, or illness. Chronic insomnia lasts for months and often needs a structured plan. Occasional bad nights are common and not automatically a disorder.
