CBT and CBT-I share the same core principles, but they aim at different things: general CBT teaches us to deal differently with life — work, relationships, anxiety, depression — while CBT-I teaches us to deal differently with the night and with sleep. CBT-I applies cognitive and behavioural tools in a highly precise, goal-directed way, focused on sleep and only sleep. It is the NICE-recommended first-line treatment for chronic insomnia.
If you have tried sleeping tablets, kept to good sleep hygiene, and perhaps found it helped a little — but only for a short while — it is natural to ask: so what actually works for insomnia?
The answer leading the field of sleep medicine today, recommended by international sleep bodies as well as NICE and the NHS, is cognitive behavioural therapy for insomnia (CBT-I).
What is CBT-I?
It is important to understand: CBT-I is not “just another talking therapy”. It is a structured, focused treatment — a kind of training programme for the brain and body — designed to systematically dismantle the insomnia cycle: the habits that build up around sleep, the thoughts that raise arousal, the fear of the night, and the problematic link that forms between the bed and wakefulness and tension.
Because of its high effectiveness, CBT-I is considered the gold standard — the treatment of choice for chronic insomnia.
How is CBT-I different from general CBT?
Most people have heard of “regular” CBT, a common treatment for anxiety, depression or stress. CBT-I uses the same basic principles — but applies them in a very precise, goal-directed way: for sleep, and only sleep.
In general CBT, the work focuses on broad patterns of thinking and behaviour: work, relationships, self-image, general anxiety or depression. It deals with everyday worries and beliefs about ourselves and the world, using tools such as exposure, habit change and stress reduction.
In CBT-I, by contrast, all the attention is directed at patterns connected directly to sleep:
- The thoughts around sleep (“I must get eight hours”, “if I don’t sleep, my day is ruined”)
- What happens in the bed itself (staring at the clock, scrolling on the phone, trying to “force” sleep)
- The link that forms between the bed and tension, frustration and arousal
CBT-I uses particularly powerful behavioural tools, such as stimulus control and sleep restriction, while at the same time working in a focused way on changing thoughts and beliefs around sleep.
You can think of it like this: general CBT teaches us to deal differently with life. CBT-I teaches us to deal differently with the night and with sleep.
The three pillars of CBT-I
CBT-I rests on three main components that work together:
- The behavioural pillar — changing the habits that strengthen insomnia over time.
- The cognitive pillar — changing how we relate to thoughts and pressure around sleep.
- The educational pillar — a deep yet simple understanding of how sleep really works, and what truly affects it.
If you want to understand which approach fits your situation, take a short insomnia self-assessment or book a consultation with Dr Jonathan Kushnir, clinical psychologist (HCPC PYL042430).
