What Is Insomnia?
Insomnia is a common sleep disorder characterised by a person's difficulty falling asleep, staying asleep, or waking up too early and being unable to return to sleep. It affects both the quantity and quality of sleep, leading to daytime tiredness, irritability, and difficulty concentrating. Insomnia can be short-term, triggered by stress or routine changes, or long-term, lasting for weeks or months due to underlying medical, psychological, or lifestyle factors.
