Insomnia and CBT-I, the first-line treatment.

CBT-I is more effective than sleeping tablets for chronic insomnia — with lasting effects and no rebound. Here is what it involves, and how to access it.

    Sourced from evidence

    Every claim is checked against NICE, the AASM or a peer-reviewed source you can see at the end.

  • 03

    Practical, not preachy

    A clear-eyed look at what CBT-I actually involves — no vague advice, no supplement upsells.

Key facts

CBT-I at a glance.

The essentials, in plain English — what CBT-I is, who it helps, the evidence behind it, and how to access it in the UK.

  • What CBT-I is

    A structured 6-8 week cognitive-behavioural programme that retrains the sleep system — not a pill and not a relaxation tape.

  • Who it is for

    Adults with chronic insomnia — poor sleep for more than 4 weeks despite reasonable sleep habits.

  • The evidence

    Superior to hypnotics in head-to-head RCTs, with effects that last long after treatment ends and no rebound.

  • How to access it in the UK

    NHS-commissioned Sleepstation in many areas, digital apps (Sleepio), private clinics, and some direct NHS referrals.

  • The core techniques

    Stimulus control, sleep restriction, cognitive work on unhelpful sleep beliefs, and relaxation training.

  • When to escalate first

    If obstructive sleep apnoea is suspected — snoring, pauses, gasping — get a sleep study before starting CBT-I.

Why this guide matters

Chronic insomnia deserves the right treatment.

Sleeping tablets are still handed out as if they were first-line. CBT-I is — and the difference in long-term outcomes is stark.

  • Pills sedate; CBT-I retrains

    Hypnotics dampen arousal for a night. CBT-I rebuilds the sleep system, and the gains last.

  • The evidence is clear and consistent

    NICE, the AASM and the British Sleep Society all place CBT-I above hypnotics for chronic insomnia.

  • Access has improved dramatically

    Digital CBT-I means you no longer need a specialist appointment to start effective treatment.

The programme

What a CBT-I course actually looks like.

Seven steps that turn a chronic insomnia problem into a treatable, structured programme — typically over 6-8 weeks.

  1. 01

    Assess

    Confirm it is insomnia, not sleep apnoea

    Screen with STOP-BANG. Loud snoring, witnessed pauses or gasping mean a sleep study comes first — CBT-I will not fix OSA.

  2. 02

    Assess

    Keep a sleep diary for 1-2 weeks

    Bedtime, sleep-onset time, awakenings, wake time. This baseline drives every later decision.

  3. 03

    Assess

    Set a fixed wake time

    Same time every day — the anchor for the whole programme. No weekend lie-ins during CBT-I.

  4. 04

    Restrict

    Restrict time in bed

    To actual sleep + 30 minutes. Uncomfortable in week one; it consolidates sleep and rebuilds sleep drive fast.

  5. 05

    Restrict

    Apply stimulus control

    Bed for sleep only. If not asleep within 20 minutes, get up — return only when sleepy. Rebuilds the bed–sleep link.

  6. 06

    Consolidate

    Cognitive work on sleep beliefs

    Test catastrophic thoughts (‘I won’t function tomorrow’). Reduce sleep effort — trying harder makes it worse.

  7. 07

    Consolidate

    Gradually widen the sleep window

    Once sleep efficiency passes 85%, add 15 minutes back each week until you find your natural sleep need.

Typical duration: 6-8 weeks from first session to a settled sleep pattern.

Signs it affects you

Signs CBT-I is likely the right next step.

A quick self-check. Chronic patterns across several of these — beyond 4 weeks — are the CBT-I population.

  • Difficulty falling asleep

    Sleep-onset latency over 30 minutes on most nights.

  • Middle-of-night waking

    Long awake stretches in the small hours, unable to return to sleep.

  • Early-morning waking

    Waking hours before you need to, and not getting back.

  • Persistent daytime fatigue

    Tiredness that a good night’s sleep would fix — and never quite does.

  • Bedtime anxiety

    Dread of the bedroom, clock-watching, effort to fall asleep.

  • Reliance on sleeping tablets

    Nightly hypnotics for weeks or months — a signal to consider CBT-I.

  • Sleep-related rumination

    Looping thoughts about how little you’ve slept and what tomorrow will bring.

  • Red flag — OSA symptoms

    Loud snoring, witnessed pauses, morning headache — get a sleep study before CBT-I.

How CBT-I works

The components of a CBT-I programme.

Eight elements — the core CBT-I techniques plus the adjuncts that sometimes sit alongside them.

  • CBT-I programme

    Digital or in-person — Sleepstation is the main NHS-commissioned option in the UK. Typically 6-8 weeks.

  • Sleep restriction therapy

    Deliberately shrink time in bed to match actual sleep. The engine of CBT-I — hard for a week, then it works.

  • Stimulus control

    Bed for sleep only; the 20-minute rule. Rebuilds the automatic bed–sleep association.

  • Cognitive restructuring

    Identify and test catastrophic sleep beliefs. Reduces effort, reduces arousal.

  • Relaxation training

    Diaphragmatic breathing, progressive muscle relaxation, guided imagery. Lowers pre-sleep arousal.

  • Sleep-diary tracking

    Daily log throughout — the data that drives each week’s adjustment.

  • Time-limited hypnotic bridge

    Occasionally used short-term alongside CBT-I. Not a long-term answer.

  • Melatonin in over-55s

    Licensed short-term for adults over 55. Adjunct at best — not a substitute for CBT-I.

A quiet reminder

This guide is for information, not medical advice.

If insomnia is affecting your life or has lasted more than a month, please see your GP — a formal assessment and a referral to CBT-I is the usual next step.

Red flags

When something else needs treating first.

These signs point to a different or additional problem — CBT-I alone will not resolve them. Escalate.

  • Loud snoring with pauses

    Suggests obstructive sleep apnoea — get a sleep study before starting CBT-I.

  • Falling asleep while driving

    A legal and safety emergency — do not drive; seek same-day assessment.

  • Waking gasping

    Especially with morning headache — investigate for OSA first.

  • Insomnia with depression

    Treat the two together; insomnia is a maintaining factor for low mood.

  • Insomnia with new medication

    Steroids, stimulants, beta-blockers, some antidepressants — review with a GP.

  • Restless legs at night

    A creeping urge to move the legs — treatable, but a different diagnosis.

  • Acting out dreams

    Especially in older adults — can herald neurological conditions.

  • Chronic hypnotic use

    Nightly sleeping tablets for months — plan a supervised taper alongside CBT-I.

  • Insomnia in pregnancy

    Especially with snoring or restless legs — discuss with your midwife or GP.

Making it stick

The programme works if you work the programme.

Four principles that separate people who complete CBT-I successfully from people who abandon it in week two.

A quiet reminder

Adherence beats effort, every time.

Following the sleep window and diary daily — even when it feels rough — is what makes CBT-I work.

  1. 01 Commitment

    The first two weeks are hard

    Sleep restriction feels worse before it feels better. Sticking with it is the whole point.

  2. 02 Structure

    Work the programme, not around it

    Fixed wake time, fixed sleep window, daily diary — the structure is doing the work.

  3. 03 Expectations

    You are rebuilding sleep drive

    CBT-I retrains a dysregulated system. Effects last long after the programme ends.

  4. 04 Escalation

    If nothing shifts in 6-8 weeks

    Return to your GP — re-screen for OSA, mood, restless legs, or medication effects.

Frequently asked

Everything we get asked about CBT-I.

Quick answers on access, evidence, sleep restriction, and how CBT-I sits alongside medication.

  • What is CBT-I, actually?

    A structured 6-8 week programme combining sleep restriction, stimulus control, cognitive work on sleep beliefs, and relaxation training. It retrains the sleep system rather than sedating it.

  • Is CBT-I really better than sleeping tablets?

    Yes — head-to-head randomised trials show CBT-I matches or beats hypnotics in the short term and clearly outperforms them long-term. Effects persist after treatment ends, with no rebound insomnia.

  • How do I access CBT-I on the NHS?

    Sleepstation is commissioned by many NHS regions and takes GP referrals. Sleepio is available in some areas. Ask your GP what is funded locally — availability varies.

  • What if I cannot access an NHS programme?

    Digital CBT-I (Sleepio, Sleepstation self-pay) or a private clinical psychologist trained in CBT-I. Digital programmes have good evidence and cost far less than face-to-face.

  • Why does sleep restriction work?

    Restricting time in bed rebuilds sleep pressure and breaks the association between bed and being awake. The first week feels worse; by week two-three, sleep consolidates.

  • Do I have to stop sleeping tablets first?

    No — CBT-I can start alongside a stable dose. A supervised taper usually follows once sleep has improved. Do not stop hypnotics abruptly.
