Cognitive behavioral therapy for insomnia, often shortened to CBT-I, is the first-line treatment recommended by sleep specialists. It works at least as well as medication in the short term and continues to work after the sessions end.
Why CBT-I comes first
Sleep medications can help with a short crisis. For chronic insomnia, the benefit tends to fade once the medication stops. CBT-I changes the behaviors and thoughts that keep insomnia going, so the benefit lasts.
The parts of a CBT-I program
A full program covers four areas:
- Sleep window — keeping the same wake time every day, including weekends, and only going to bed when sleepy.
- Stimulus control — using the bed only for sleep, and leaving the bed if you are awake for more than twenty minutes.
- Cognitive work — examining the thoughts that arrive at 3am (“I will not function tomorrow”) and replacing them with more accurate ones.
- Sleep hygiene — light, caffeine, alcohol, and screen habits that affect sleep.
What to expect
A program runs for six to eight sessions, usually weekly. Some patients see meaningful improvement after two sessions. Improvement is measured by sleep efficiency — the share of time in bed that you are actually asleep.
What to track before the first visit
Bring two weeks of records. For each day, note:
- Time you got into bed.
- Time you estimate you fell asleep.
- Number and length of awakenings.
- Time you got out of bed.
A paper notebook is fine. The data does not need to be exact.
When medication is added
Medication is sometimes used alongside CBT-I, particularly when the insomnia is tied to another condition. The combination is decided with a clinician, not added on your own.
