CBT-I
The first-line treatment for chronic insomnia. Not a list of tips, a structured plan that changes how your brain treats the bed.
In short
- CBT-I is the first-line treatment for chronic insomnia (AASM strong recommendation; ACP first-line).
- It’s a package: stimulus control, sleep restriction, cognitive work, relaxation, and some sleep education.
- Typically 4–8 sessions. Most people sleep better within a few weeks and keep it after treatment ends.
- Sleep hygiene alone isn’t enough.
Does it work?
Trauer 2015 meta-analysis. Gains held at later follow-ups, with no adverse outcomes reported. Total sleep time rose a little (about 8 minutes, not statistically significant). The big change is less time lying awake.
Who recommends it
The American Academy of Sleep Medicine gives multicomponent CBT-I a strong recommendation; individual pieces like stimulus control, sleep restriction and relaxation get conditional ones. The American College of Physicians says use CBT-I first. The 2023 European guideline calls it first-line at any age, including people with other conditions, in person or digital. (AASM 2021; ACP 2016; Riemann 2023)
How long it takes
The AASM patient guide puts it at 4–8 sessions, with brief versions in 1–4. Their provider sheet describes full CBT-I as 6–10 hour-long sessions over 6–20 weeks, and Brief Behavioral Treatment for Insomnia as 4 weekly sessions. In person, by telehealth, or digital. (AASM patient guide; AASM BBTI fact sheet)
Stimulus control
Re-teach your brain that bed means sleep.
The rules
- Go to bed only when sleepy (eyes heavy, nodding), not just tired.
- Use the bed for sleep and sex only. No scrolling, work or worrying there.
- If you can’t sleep in about 20 minutes, get up. Go somewhere dim, do something calm, come back when sleepy. Repeat as needed. Judge it by feel, don’t watch the clock.
- Get up at the same time every day, weekends included.
- Cut back on daytime naps, especially long ones.

Sleep restriction (your sleep window)
Less time in bed, at first, to get better sleep.
The idea
If you’re in bed 8½ hours and asleep for 5½, you’re spending 3 hours a night practicing being awake in bed. Shrinking time in bed to about your real sleep time builds sleep pressure, so sleep gets deeper and more solid. Then you widen the window week by week. (Spielman et al. 2011; Spielman 1987)
How it’s set
Keep a sleep diary for 1–2 weeks. Sleep efficiency = time asleep ÷ time in bed. Restriction is used when it’s under 85% (80% for older adults). The window starts at your average sleep time, never under 5 hours, with a fixed rise time. Then adjust weekly by the rule below. (Spielman et al. 2011)
Expect this
The first week or two you’ll likely feel sleepier. That’s the mechanism working. Be careful driving. Skip it, or get medical input first, if you have untreated sleep apnea, epilepsy, parasomnias, or a safety-sensitive job. (Spielman et al. 2011)

Sleep efficiency & your starting window
Use your average from 1–2 weeks of a sleep diary. Drag the sliders.
Weekly adjustment rule
- Under 85%: cut the window 15–30 min (not below 5 h).
- 85–89%: hold steady.
- 90% or more: add 15–30 min.
Rules from Spielman, Yang & Glovinsky (2011): window starts at your average sleep time, minimum 5 hours; older adults use 80/85%. Sleep restriction isn’t for people with untreated sleep apnea, epilepsy, parasomnias, or safety-sensitive jobs like driving. Do this with a CBT-I clinician.
The thinking side
What we work on
- Catastrophic predictions (“If I don’t sleep tonight, tomorrow is ruined”). Test them against your diary.
- Trying hard to sleep. Effort is arousal. The goal is to let sleep come.
- Clock-watching. Turn the clock away.
- Safety behaviors: cancelling plans, extra caffeine, napping. They keep the fear going.
- Worry in bed. Give it a slot earlier in the evening: write it down, plan a next step, close the notebook.
(Harvey 2002)
Relaxation
Options
Progressive muscle relaxation, slow breathing, meditation. Practice in the day first so it works at night. Use it to settle, not to force sleep. (AASM patient guide)
Sleep hygiene
Fine to do, weak on its own.
The honest version
Cut caffeine after midday, keep alcohol away from bedtime, keep the room dark, cool and quiet, keep the evening calm. Helpful habits. But the AASM recommends against hygiene as the only treatment for chronic insomnia, and its patient guide says most people need more than that. (AASM 2021; AASM patient guide)
