When sleep tips stop helping: understanding CBT-I

There is a particular frustration in doing all the things you were told would help and still watching the night pass. You buy the curtains. You stop answering emails in bed. Someone mentions a tea, an app or an earlier bedtime, and you wonder whether you have simply missed the right trick.

If that sounds familiar, it helps to know that persistent insomnia has treatments that go beyond general sleep tips. One of them is cognitive behavioural therapy for insomnia, usually shortened to CBT-I. The name can sound technical. The conversation it starts is very practical: what is happening around your sleep, and what can be changed with the right support?

What CBT-I is trying to change

CBT-I brings together several approaches to the thoughts and behaviours that can maintain insomnia. The American Academy of Sleep Medicine strongly recommends this combined treatment for adults with chronic insomnia. It also advises against offering sleep hygiene alone as the treatment. That distinction matters if familiar advice about light, caffeine and routines has become a list you follow without getting relief. ^[1]

The word “behavioural” can feel like an accusation. It shouldn’t. Discussing habits and responses is a way to find things a treatment can work with; it does not mean you chose the problem or should have solved it already.

For example, imagine beginning each evening by calculating how much sleep you need to cope with tomorrow. By bedtime, you are checking whether you feel sleepy enough. If you wake, you start the calculation again. That is a useful pattern to describe to a practitioner, even if you have no idea how to change it yourself.

What might happen in a programme?

The NIH describes a programme that may include working with sleep-related worries, rebuilding the connection between bed and sleep, relaxation, and changes to the amount of time spent in bed. Delivery can be in person, by telephone or online. The details should be discussed with someone qualified to provide the treatment. ^[2]

There is more to this than receiving a handout. Before agreeing to a programme, it is reasonable to ask what the sessions involve, what you will practise between them, how progress will be reviewed and who you can contact if something is difficult. Those questions are especially useful when a website or app describes itself as CBT-I.

One component you may hear about is sleep restriction: a planned adjustment to time in bed. Reading the name without the context can make it sound like an instruction to deprive yourself of sleep. It belongs within a treatment plan. Avoid inventing an aggressive sleep schedule from a few lines online; ask how any change would fit your health, work and safety needs. ^[2]

Why the ordinary advice can feel so inadequate

A comfortable room and a workable routine still have a place. But someone who has struggled for months may already have tried those things repeatedly. Being told to buy better bedding can feel dismissive when the real question is how to stop spending so much of the night awake.

It may help to explain that gap directly at an appointment: “I know the basic advice. I’m doing much of it, but this is still affecting my day.” You do not have to arrive with the correct clinical vocabulary. Bring a clear account of what is happening and ask what the next level of support looks like.

Medication may also be part of a discussion. The AASM’s 2026 guidance conditionally favours CBT-I with medication over medication alone, while generally favouring CBT-I alone over routinely adding medication. These are decisions to make with a clinician, taking preferences and circumstances into account. They are not a reason to change an existing prescription yourself. ^[3]

Bring a picture of your week, not a perfect spreadsheet

The NIH suggests keeping a sleep diary for one to two weeks before an assessment. Approximate sleeping and waking times, time awake, daytime sleepiness and relevant habits can help a clinician see the pattern. ^[4]

A few honest notes are more useful than spending the night monitoring yourself. An entry might read: “Went to bed around eleven. Took a while to settle. Woke before the alarm and felt worn out in the afternoon.” Add what you have tried and whether it seemed to make any difference. The point is to give the conversation something concrete to work with.

If your schedule changes, say so. Early starts, overnight responsibilities and irregular shifts are part of the situation a plan has to fit. A plan that only works on an imaginary quiet week is difficult to use.

A more useful question than “What else can I buy?”

Try asking: “Is CBT-I suitable for this problem, and how can I access a supported programme?” Follow that with questions about the provider, the format, the time commitment and what happens if you need help adapting it.

There may be waiting lists or practical barriers. It is still worth naming the treatment you want to discuss instead of leaving with another vague instruction to relax. You can also read our guide to preparing for a sleep appointment.

You do not need to prove that you have exhausted every pillow, playlist and evening routine before asking for help. Describing what your nights are like, and what they are costing you during the day, is a sensible place to begin.
