What CBT-I is
Cognitive behavioral therapy for insomnia, or CBT-I, is a short, structured treatment that works on the habits and thoughts that keep poor sleep going. It isn’t general advice about sleep, and it doesn’t rely on medication.
What the guidelines say
The American College of Physicians recommends CBT-I as the first treatment for chronic insomnia in adults, and the American Academy of Sleep Medicine strongly recommends it. The European Insomnia Guideline does the same. Medication still has a place for some people, and that is a decision to make with a prescriber.
The parts
CBT-I is usually taught over four to eight sessions, with a clinician, in a group, or through a structured program. Most versions include these parts. Sleep Toolbox has a tool or a short read for each one.
- A sleep diary. A few minutes each morning on the night before.
- Stimulus control. A small set of rules that help the bed and sleep go together again.
- Sleep restriction, which Sleep Toolbox calls the sleep window. Time in bed is matched to how much you’re sleeping now, then grows as sleep fills it.
- Cognitive work. A look at worries and beliefs about sleep that make nights harder.
- Relaxation. Ways to lower the tension many people carry into bed.
- Education. How sleep works, and which habits matter.
The guidelines recommend the parts together. Stimulus control, the sleep window, and relaxation also have support on their own. Sleep habits alone aren’t recommended as a treatment for insomnia.
Why the diary comes first
Memory is a poor judge of sleep. A bad night stands out, and the good ones blur together. People with insomnia often underestimate how much they sleep, and sometimes overestimate it.
A week or two of diary gives a fairer picture. It shows how long you spend in bed, how much of that time you’re asleep, and how the nights vary. The sleep window is built straight from those numbers, so it can only be as good as the diary.
The diary isn’t a test. Rough guesses are fine, and a night you missed can be added for up to two days afterward.
What it’s like
CBT-I asks for effort, and the first couple of weeks of the sleep window are often hard. Many people feel sleepier during the day before their nights settle. It helps to know that going in, and to plan the start for a stretch of weeks without big deadlines or travel.
On your own or with a clinician
Many people work through CBT-I on their own with a book or an app, and research on self-guided versions is encouraging. A clinician trained in behavioral sleep medicine can tailor the steps, check for other sleep problems, and help when things stall. If you have a health condition, take medication that affects sleep, or drive for work, talk with a health care provider before you start the sleep window.
