Intro

Cognitive Behavioral Therapy for Insomnia (CBT-I) is the most effective long-term treatment for chronic insomnia. Unlike sleeping pills, which only mask symptoms, CBT-I helps people change the thoughts and behaviors that perpetuate sleeplessness. It is recommended as the first-line therapy by major sleep and medical organizations worldwide.

Key Points

CBT-I is the gold standard treatment for persistent insomnia.
It usually involves 6–8 sessions with a therapist or validated online program.
Techniques include sleep restriction, stimulus control, cognitive restructuring, relaxation training, and sleep hygiene.
Results are long-lasting, with most patients improving within 6–8 weeks.
Available in person, via telehealth, and through digital programs.

Background

Insomnia affects up to one-third of adults at some point, with 10% experiencing chronic insomnia. CBT-I was developed to directly target the underlying psychological and behavioral causes of insomnia rather than just providing temporary sedation.

How CBT-I Works

CBT-I combines behavioral and cognitive techniques to break the cycle of sleeplessness:

Sleep Restriction
Reducing time in bed to match actual sleep duration, then gradually extending it as sleep improves.
Stimulus Control
Training the brain to associate bed only with sleep and sex — not wakefulness, worry, or screens.
Cognitive Restructuring
Identifying and challenging anxious or unrealistic sleep-related thoughts.
Relaxation Training
Learning calming techniques such as progressive muscle relaxation, breathing exercises, or mindfulness.
Sleep Hygiene
Optimizing the sleep environment and daily habits (light, temperature, caffeine, screens).
