Cognitive Behavioral Therapy for Insomnia (CBT-I) is a structured program designed to help individuals overcome sleep difficulties. It focuses on changing negative thoughts and behaviors related to sleep, teaching patients to develop healthier sleep habits. CBT-I typically includes techniques such as sleep restriction, stimulus control, and cognitive restructuring. The therapy is usually delivered over several sessions with a trained therapist or through self-help materials. Research shows that CBT-I is effective for many people, often leading to long-lasting improvements in sleep quality without the need for medication.
