How to do it
- Choose a neutral word — a common one with no emotional charge. Something like BEDROOM, PICTURE, or MARKET works well.
- Take the first letter. Generate a word starting with that letter. Any word. Picture it for a moment.
- Move to the second letter, then the third, and so on.
- When you run out of letters, choose another neutral word and start again.
With BEDROOM: B — bed, bear, button. E — elephant, echo, engine. D — door, dog, dress. Then R, O, O, M. Do not try to make them connected. If the words stop coming, start a new word.
Why randomness matters
The thinking that keeps insomniacs awake is narrative — it has plot, consequence, and momentum. One worry leads to the next, and each one raises arousal a little more. Narrative thinking is what your brain does when it believes something needs solving.
Random word generation cannot form a narrative. Each word is unrelated to the last, so no thread develops, and the system that was scanning for problems gets a task it can complete without consequence. You are not suppressing thought — you are replacing an arousing mode with a neutral one, which is far easier.
Practical tips
- Practise during the day first. Learning it while tired and frustrated is harder.
- Do not worry about doing it right. Boring nonsense is the point.
- If the words become emotional or work-related, abandon that word and pick another.
- Combine with a body practice if your mind is racing because your body is tight — try Feldenkrais movement first, shuffling after.
- Use it at 3am too. See waking up at 3am.
Evidence status
Cognitive shuffling is newer than the established CBT-I techniques and has less research behind it — early work is encouraging, but it should not be treated as equivalent to stimulus control or sleep restriction. It costs nothing, takes two minutes, and some people find it dramatically effective. It is worth trying, and it is not worth arguing about.
If shuffling does not work for you
Some people find word generation mildly activating. Alternatives with a similar logic:
- Paradoxical intention — try to stay awake instead.
- Body scan — give attention a slow somatic task.
- Extended-exhale breathing — work on the autonomic side directly.
