CBT-I: The Insomnia Treatment That Outperforms Medication
Cognitive Behavioural Therapy for Insomnia is the clinical gold standard. Here is what actually happens across six weeks of treatment.
Sleeping pills work — for a few weeks. After that, tolerance builds, the underlying problem remains, and stopping the medication often makes insomnia worse than it was before. CBT-I (Cognitive Behavioural Therapy for Insomnia) is the only treatment shown, in head-to-head trials, to outperform medication at six months and beyond.
What CBT-I actually does
CBT-I retrains two things: the behaviours that keep you awake, and the thoughts that make staying awake feel catastrophic. It typically runs for six sessions, one per week.
Week 1–2: Sleep restriction
Counter-intuitively, we shorten your time in bed. If you sleep 5.5 hours but spend 8 in bed, we compress your window to 6. This builds sleep pressure and consolidates fragmented sleep into a solid block.
Week 3–4: Stimulus control
The bed becomes a cue for sleep only — no scrolling, no working, no anxious lying. If you are awake more than 15 minutes, you get up.
Week 5–6: Cognitive restructuring
We dismantle the thought spirals — 'I'll be useless tomorrow', 'I must get eight hours' — that turn one bad night into a chronic problem.
What the evidence shows
- 70–80% of patients see meaningful improvement after six weeks.
- Gains hold at 12-month follow-up, unlike pharmacotherapy.
- It is recommended as first-line treatment by the American College of Physicians and the European Sleep Research Society.
If you have battled insomnia for more than three months, CBT-I is almost certainly the intervention you have not yet tried.
