What is Insomnia?

Insomnia is a common sleep disorder characterized by persistent difficulty in falling asleep, staying asleep, or achieving restorative sleep, despite having adequate opportunity to sleep. This condition leads to impaired daytime functioning and can significantly affect one’s quality of life, health, and well-being.
