CBT for Insomnia (CBT-I): What It Is, How It Works and Where to Get It

CBT for insomnia, usually called CBT-I, is the treatment Australian GPs are advised to try first for long-term trouble sleeping. It isn't a pill or a gadget. It's a short, structured program that changes the habits and thoughts that keep insomnia going. This guide covers what CBT-I is, its main parts, what a course looks like, how well it works, and how to get it in Australia, including free online options.

The short answer: CBT-I is a structured program, usually four to eight sessions, that retrains your sleep using techniques like sleep restriction, stimulus control, relaxation and changing unhelpful thoughts about sleep. The Royal Australian College of General Practitioners recommends it as a first treatment for insomnia. It helps most people who complete it, and unlike sleeping tablets, the benefits last after it ends. You can do it with a psychologist, in a group or through free online programs. Start by talking to your GP.

This guide is general information, not medical advice.

What CBT-I is

The Sleep Health Foundation describes CBT-I as a way to help people with insomnia sleep better by working on the thoughts, behaviours and processes that cause sleep problems. It has been recommended as a best first treatment by the Royal Australian College of General Practitioners and the American College of Physicians (source).

Healthdirect puts it simply: CBT helps you change how you think about sleep and feel less anxious or worried about it, and it's usually the first type of treatment to try when other strategies haven't worked (source).

The idea behind it is that whatever started your insomnia (stress, illness, a new baby, shift work) is often not what keeps it going. What keeps it going is what you do in response: lying in bed longer to "catch up", worrying about tomorrow, napping, checking the clock. CBT-I targets those.

The main parts of CBT-I

Part	What it involves	Why it helps
Education	Learning how sleep works and what keeps insomnia going	Takes the mystery and some of the fear out of bad nights
Sleep restriction	Temporarily limiting time in bed to roughly the time you actually sleep	Builds sleep pressure so sleep becomes deeper and more solid
Stimulus control	Bed only for sleep (and sex); get up if you can't sleep	Retrains your brain to link bed with sleeping, not lying awake
Relaxation	Breathing, imagery, progressive muscle relaxation	Lowers the arousal that keeps you awake
Cognitive work	Spotting and challenging unhelpful thoughts about sleep	Reduces the "I'll never sleep" spiral
Sleep diary	Recording your sleep each morning	Tracks patterns and guides each step

Sleep restriction sounds harsh, and the first week or two can leave you more tired. The Sleep Health Foundation describes the goal as spending about 85 per cent of your time in bed actually asleep. Your time in bed is then gradually extended as sleep improves. Because it causes extra sleepiness early on, it's best done with guidance, and take care with driving and machinery while you adjust.

A fixed wake-up time is the anchor for most of this. See why a fixed wake-up time works.

What a course looks like

According to the Sleep Health Foundation, CBT-I typically involves four to eight sessions, held weekly or fortnightly. Sleep diaries are the "homework" between sessions, so you and your therapist can see what's changing. Our guide on how to keep a sleep diary shows you what to record.

A typical course runs something like this:

1. Assessment. Your sleep history, health, medicines, mood and a week or two of diary entries.
2. Setting a sleep window. A fixed wake-up time and a later bedtime, based on your diary.
3. Stimulus control. Clear rules for what to do when you can't sleep.
4. Adjusting the window. Each week, your time in bed is adjusted based on how much you slept.
5. Working on thoughts. Tackling worries such as "if I don't get eight hours, tomorrow is ruined". Racing thoughts at night covers some of these techniques.
6. Relapse planning. What to do if a bad patch returns.

How well it works

The Sleep Health Foundation reports that CBT-I has been shown to improve insomnia symptoms in up to 80 per cent of people, and that 90 per cent of them also reduce or stop using sleep medications. It also notes the benefits of CBT-I don't stop when therapy ends, because you keep using the strategies.

The Foundation's insomnia fact sheet adds that CBT-I has been shown to be more effective in the medium and long term than sleeping tablets (source). It says sleeping pills taken occasionally can give you a good night, but taken often, you get used to them and they work less well. If you're considering other options, our guide to melatonin in Australia explains where that fits.

How to get CBT-I in Australia

You have several routes:

• Your GP. Talking to your GP is the starting point. They can point you to local sleep services, and may be able to set up a mental health treatment plan, which the Sleep Health Foundation notes can cover up to 10 Medicare-subsidised psychology sessions a year.
• A psychologist with training in sleep. Ask whether they offer CBT-I specifically, not general CBT.
• Free online programs. The Sleep Health Foundation lists This Way Up's Managing Insomnia course, the MindSpot Sleep Course (eight weeks) and the CBT-I Coach app as free options, along with other digital programs.
• Group programs run in some cities, such as Brisbane, Sydney and Perth.

When to see your GP

See your GP if you've had trouble sleeping for more than a few weeks, if poor sleep is affecting your mood, work or driving, or if you snore loudly, stop breathing in your sleep or have restless legs. Those may need different treatment, and CBT-I works best once other causes have been checked. For a broader look at options, see insomnia: what helps.

Where the Sovune Nudge fits

We make the Sovune Nudge, a silent alarm wristband, so we're not neutral. It isn't a treatment for insomnia. But CBT-I depends on getting up at the same time every day, and a reliable alarm that doesn't involve your phone makes that easier.

• Set on the band itself. No app, no phone, no pairing, so the phone can stay out of the bedroom.
• Three separate alarms, useful for a fixed wake-up time plus a reminder to start winding down.
• Wakes you with vibration on your wrist, starting as a gentle tap and building through three intensity levels over a full minute.
• No light in the room except a small display when you press the button, so there's no clock glowing at you at 3am.

It comes with a 30-day money-back guarantee.

Quick answers

How long does CBT-I take? Usually four to eight sessions, weekly or fortnightly, with diary homework between sessions.

Can I do CBT-I on my own? Yes, through structured online programs such as This Way Up or the MindSpot Sleep Course. Some people do better with a therapist.

Is CBT-I better than sleeping pills? For long-term insomnia, it has been shown to work better in the medium and long term, and its effects last after treatment ends.

Why do I feel more tired at first? Sleep restriction cuts your time in bed early on to build sleep pressure. The tiredness usually eases as your sleep consolidates.
