If you’ve struggled with insomnia for months, there’s a good chance no one has mentioned CBT-I. That’s a shame: the American College of Physicians recommends it as the first-line treatment for chronic insomnia in adults — ahead of medication.
What CBT-I is
CBT-I is a structured program, usually four to eight sessions, that targets the thoughts and habits that keep insomnia going. It can be delivered by a therapist, in groups, or through validated digital programs.
The core components
Sleep restriction. Counterintuitive but powerful: you temporarily limit time in bed to roughly the time you actually sleep. This builds sleep pressure, so sleep becomes deeper and more consolidated. Time in bed is then gradually extended.
Stimulus control. The bed is for sleep (and sex) only. If you’re awake for what feels like more than about 20 minutes, get up, do something calm in dim light, and return when sleepy. Over time, the brain relearns that bed means sleep.
Cognitive work. Insomnia is fuelled by worries like “If I don’t sleep, tomorrow will be a disaster.” CBT-I helps examine and soften these thoughts, which lowers the arousal that keeps you awake.
Sleep hygiene and relaxation. Consistent wake times, a wind-down routine, and techniques to calm the body round out the program.
How well it works
Most people who complete CBT-I see meaningful improvement in how quickly they fall asleep and how long they stay awake at night. Unlike sleeping pills, the benefits tend to last after treatment ends. Studies in women going through menopause show it helps there too — including when night sweats are part of the picture.
The catch
The first two weeks can be hard: sleep restriction often makes you sleepier during the day before things improve. That’s expected and temporary. People with certain conditions, such as bipolar disorder or seizure disorders, should do sleep restriction only under supervision.
Ask your clinician for a referral, or look for a digital CBT-I program with published evidence behind it.
