Cognitive Behavioral Therapy for Insomnia (CBT-I) is a structured psychological treatment that helps people change thoughts and behaviors that interfere with sleep. It focuses on identifying patterns—such as worrying about sleep, spending too much time in bed awake, irregular sleep schedules, or habits like late-night screen use—that condition the brain to stay alert rather than sleep. Through techniques such as sleep restriction, stimulus control (associating the bed only with sleep), relaxation training, and cognitive restructuring, CBT-I helps retrain the mind and body to develop a stronger, more consistent sleep–wake rhythm.

CBT-I is effective because it addresses the underlying causes that maintain chronic insomnia rather than simply masking symptoms. Insomnia often persists due to learned associations (e.g., the bed becoming linked with frustration) and unhelpful beliefs about sleep that increase anxiety at night. By correcting these patterns, CBT-I reduces physiological and mental arousal, improves sleep efficiency, and strengthens the brain’s natural sleep drive. It is now the gold standard treatment for insomnia. Research shows it produces long-lasting improvements and is often as effective as sleep medications in the short term, while providing more durable benefits after treatment ends.
