Cognitive Shuffling: The Random-Word Trick for a Busy Mind
Cognitive shuffling is a bedtime trick for a mind that won’t stop talking: you pick a plain word, and for each of its letters you think of random, unconnected things starting with that letter, picturing each one for a moment. Kursi, kela, kabootar. Worry needs a story to run on; a stream of unrelated pictures gives it nothing, and the brain drifts off the way it does naturally before sleep.
In brief
- What: random, unrelated words and images, one letter at a time
- Who it’s for: people who replay conversations, plan tomorrow, or worry in bed
- Time: 5 to 15 minutes, no app needed
- Evidence: a newer technique from a Canadian sleep researcher; small trials, promising, not proven
- Won’t fix: caffeine, heat, a late nap, or chronic insomnia on its own

What cognitive shuffling is and where it came from
The method was developed in the 2010s by Luc Beaudoin, a cognitive scientist at Simon Fraser University in Canada, who noticed something about how people fall asleep normally: in the last minutes before sleep, thinking loses its thread, images float up unconnected, and nobody minds. A worried brain keeps its thread tight. It rehearses, plans and argues. Beaudoin’s idea was to imitate the natural drift on purpose, feeding the mind harmless, disconnected pictures until it stops steering.
He called it “serial diverse imagining”. The internet renamed it cognitive shuffling, and that’s the name that stuck. There is an app version, but the do-it-yourself form needs nothing but a word.
How to do cognitive shuffling, step by step
- Get comfortable first: lights off, phone across the room, 2 to 3 slow breaths. Don’t start while you’re still fidgeting.
- Choose a seed word: a neutral one, 5 to 8 letters, with no repeated letters if you can, and nothing emotional. “Kitaab”, “darwaza”, “bottle”, “garden” all work. Avoid your boss’s name.
- Take the first letter: for K, think of a word starting with K and picture it for 2 to 4 seconds. Kursi: see a chair. Then another K word, no link to the last: kela, a banana. Kabootar, a pigeon on a ledge. Kite. Kettle. Karachi.
- Keep the pictures short and dull: you’re not building a scene. One object, a second or two, next.
- Move to the next letter: when K runs dry (usually after 6 to 10 words), go to I. Imli, ice, island, ink. Then T, then A, and so on.
- Mix languages freely: Urdu, English, Punjabi, Sindhi, anything. More languages means more words and less effort.
- If you finish the word: pick another seed and go again. Most people don’t finish; they’re asleep somewhere around the third letter.
The rules are loose on purpose. Skip letters that are hard (X, Q, Z). Allow repeats if they come. If a picture is pleasant, enjoy it for a second, then move on. The only rule that matters is that the words don’t connect. “Kursi, kela, kabootar” is right. “Kursi, kitchen, kettle, khana, then what’s for lunch tomorrow” is your mind sneaking back into planning.
Why random words switch off a busy mind
A worry loop has a structure: a problem, a possible outcome, a plan, a fear about the plan, back to the problem, and it keeps going because each thought hands the baton to the next. Cognitive shuffling breaks the baton. Pigeons, bananas and chairs don’t lead anywhere; each image is a dead end, and the brain, which likes to follow threads, finds nothing to follow.
The second thing it does is occupy the part of the mind that generates language and imagery, so there’s less capacity left for the inner monologue, much like handing a restless child a jigsaw, not because the jigsaw matters but because busy hands stop pulling at the tablecloth. And the pictures resemble sleep onset anyway. Brains produce exactly this kind of random, fragmentary imagery on their own as they slide under. Shuffling doesn’t force anything. It starts the slide from the top.
Worry is a story. Give the mind a heap of unrelated pictures and the story has nowhere to go.
When the mind drifts back to work
It will. That is not failure; it’s the whole reason you’re doing this. The move is simple: notice it, don’t argue with it, go back to the letter you were on and pick the next word. No punishment, no “I’m doing it wrong”. Some nights you’ll return to the letter ten times. Each return is a small win, and the returns get rarer with practice.
Three adjustments help when the drift is strong:
Make the images more concrete. Not “kite” as a word, but a red kite on a Basant sky, the string tugging. Vivid pictures crowd out talk better than pale ones.
Slow the pace. Rushing through words turns the exercise into a task. Two to four seconds a picture is about right.
Write the worry down first. If the same thought keeps barging in, it’s usually a genuine loose end. Sit up, write it on a pad kept by the bed (“call the bank re: fee”), then lie down and start again. The mind can let go of a thing once it’s parked on paper. If worry is the main event most nights, the notebook deserves a routine of its own, and so does the 20-minute rule: awake for what feels like that long, get up, sit in dim light, come back when sleepy.
Where it fits among the other tricks
Shuffling suits people whose problem is mental noise. If your body is tense rather than your head, a top-to-bottom muscle release does more. If your heart is racing, slow breathing with a long out-breath is quicker, and the five-minute method in our bechaini at night guide is built for exactly that. Plenty of people do both: four slow breaths, then start on the letters. Our calm wind-down guide covers the room, the dinner and the phone, which no bedtime trick can compensate for.
It won’t outrun caffeine (a cup of chai is around 40 to 60 mg, and a 9 pm cup is still at work at 2 am), it won’t beat a hot room or a 6 pm nap, and it isn’t a treatment for insomnia that has settled in. For that, the habits with real evidence are the boring ones. Same wake time daily. Bed only for sleep. No clock in view.
Grandmothers had their own version of this. Counting sheep is the famous one, but in desi homes it was often reciting something long and familiar by heart, listing the names of relatives, or telling a child to imagine every shop on the way to the bazaar. All of them work the same way: a dull, repetitive task for the talking mind. Shuffling just removes the sequence, so there’s even less to hold on to.
Cognitive shuffling is harmless, but the thing it’s masking may not be. Worry that keeps you awake 3 or more nights a week for 3 months or longer, or sleep that changed suddenly along with low mood, loss of interest, or thoughts of hurting yourself, is a reason to talk to a doctor; anxiety and depression are both treatable, and no word game replaces that. So is snoring with pauses or gasping, dozing off at the wheel, or restless legs that wreck the night. Melatonin, antihistamines and herbal sleep aids aren’t a self-service add-on either; ask a pharmacist or doctor whether any of them suits you.
Cognitive shuffling: questions readers ask
Does cognitive shuffling really work?
For many people with a busy mind at bedtime, yes, and it costs nothing to try. The research is small and early, so it’s fair to call it promising rather than proven. Give it two weeks of nightly use before judging.
What word should I start with?
Anything neutral with 5 to 8 letters and few repeats: “kitaab”, “darwaza”, “garden”, “bottle”. Avoid names, work words or anything with a feeling attached. Change the seed word whenever you like; there’s no special one.
Can I do it in Urdu or Punjabi instead of English?
Do it in whichever language gives you the most words, and mix them freely. Kursi and kettle can sit side by side. More languages means more pictures and a smoother drift.
What if I keep thinking about work?
Notice it without arguing, return to your letter and pick the next word. If the same task keeps intruding, sit up and write it on a pad by the bed, then start again. Returning ten times in a night is normal at first.
How long does it take to fall asleep with it?
Most people report drifting off within 10 to 20 minutes, which is the normal range for a healthy adult anyway. If you’re still wide awake after roughly 20 minutes, get out of bed for a while rather than shuffling for an hour.
Is it the same as counting sheep?
Same family, better design. Counting sheep is a sequence, and sequences are easy for the mind to run in the background while it worries. Random pictures have no order, so there’s nothing to run alongside.
Do I need the app?
No. The app reads words to you, which some people prefer, but the self-made version works the same way and keeps the phone out of the bedroom, which is a bigger win.
Can children use cognitive shuffling?
School-age children usually love it as an “alphabet pictures” game, and it’s a kind way to settle a worrier at bedtime. It isn’t for babies or toddlers, who need a routine and safe sleep on the back, not a technique.
Can I use it when I wake at 3 am?
It’s one of the better tools for that, because it needs no light and no movement. Keep the phone off. If you’re still fully awake after about 20 minutes, get up briefly, sit somewhere dim, and return when sleepy.
Why does it sometimes make me more awake?
Usually because the pictures got interesting or connected, or you were racing through them like a test. Slow down to two to four seconds per image and keep them dull. If it consistently wakes you up, switch to a body scan instead; not every trick suits every mind.
Is cognitive shuffling a treatment for insomnia?
No. It’s a bedtime aid. Long-term insomnia (3 or more nights a week for 3 months) is treated with a structured programme called CBT-I, which a doctor or psychologist can arrange, and sometimes with short-term medicine they choose. Shuffling can sit alongside that, not replace it.
