The core components
Stimulus control (bed = sleep). Sleep restriction (compress time in bed to current actual sleep, then expand). Cognitive work on unhelpful beliefs about sleep. Sleep hygiene. Relaxation training. Most programmes run 4–8 weeks.
Why it outperforms pills long-term
Medication can help short-term but the effect ends when the drug stops. CBT-I retrains the sleep system, so benefits persist months and years after the programme ends.
Getting it
Ask your GP or doctor for referral. Free or low-cost digital CBT-I programmes are available in several countries. The NHS in England offers Sleepio in some regions.
