Cognitive-behavioral therapy for insomnia, often abbreviated as CBT-I, is a structured program designed to help individuals overcome sleep difficulties. It focuses on changing thoughts and behaviors that contribute to insomnia, teaching patients to develop healthier sleep habits and improve their sleep environment. The therapy typically includes techniques such as sleep restriction, stimulus control, and cognitive restructuring. By addressing the underlying issues related to sleep, CBT-I aims to reduce anxiety about sleep and promote more restful nights, making it a preferred treatment option for chronic insomnia without relying on medication.
