Counting sheep might be one of the oldest sleep tricks in the book, but scientists say there’s a better way to tell your brain it’s time to power down.
It’s called cognitive shuffling, and it works by mimicking the weird, wandering thoughts your mind naturally creates as you drift off.
Instead of wrestling with anxious thoughts or forcing yourself to relax, this technique gives your brain something simple to do—something just boring enough to help you fall asleep.
Here’s how it works and why sleep experts are calling it a game-changer for people who can’t turn their minds off at night.

What Is Cognitive Shuffling?
Cognitive shuffling is a mental exercise designed to gently occupy your mind without actually stimulating it. The goal is to distract yourself from intrusive thoughts—the kind that keep you awake replaying conversations, worrying about tomorrow, or spiraling into stress.
The technique was developed more than 15 years ago by Luc P. Beaudoin, an adjunct professor at Simon Fraser University in British Columbia. He also calls it “serial diverse imagining,” and it’s built on a simple but clever idea: if you can replicate the random, scattered thinking your brain does naturally before sleep, you can trick yourself into falling asleep faster.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
How to Do Cognitive Shuffling
Start by choosing a random, emotionally neutral word. Something like “candle” or “garden” works well. Avoid anything that might trigger strong feelings or memories.
Once you have your word, take the first letter and mentally picture objects that start with that letter. For example, if your word is “candle,” you’d start with the letter c and visualize things like a cake, a car, a castle, a cat, a carrot—anything that comes to mind.
When you run out of images for that letter, move on to the next one. With “candle,” you’d go from c to a, then n, and so on, generating new mental pictures each time.
The images don’t need to connect or make sense. In fact, the more random and unrelated they are, the better.
Why It Works: The Push-and-Pull on Your Mind
According to Alanna Hare, a consultant and specialist in sleep medicine at Royal Brompton Hospital in London, cognitive shuffling works because it creates a unique push-and-pull effect on your brain.
The technique both nudges the brain toward sleep while also quieting the worries that can prevent it.
Essentially, you’re giving your mind a task that’s just engaging enough to distract you from anxious thoughts, but not so stimulating that it keeps you awake. It’s a sweet spot that mirrors what your brain does naturally as it transitions into sleep—jumping from one unrelated thought to another without logic or emotional weight.

This kind of cognitive distraction is backed by sleep science. The American Academy of Sleep Medicine has emphasized that intrusive thoughts and rumination are among the most common barriers to falling asleep, and recommends techniques that redirect attention away from stressors.
Better Than Counting Sheep
Counting sheep has been the go-to sleep trick for generations, but it’s not particularly effective. The problem? It’s repetitive and boring, but not distracting enough.
Your mind can easily wander back to whatever was keeping you awake in the first place. Cognitive shuffling, on the other hand, requires just enough mental effort to keep you focused without activating the parts of your brain responsible for problem-solving or emotional processing.
It’s also more flexible. You can adjust the difficulty by choosing longer or shorter words, or by challenging yourself to come up with more obscure images.
Who Should Try Cognitive Shuffling?
This technique is especially helpful for people who struggle with racing thoughts at bedtime. If you’re someone who lies awake replaying conversations, making mental to-do lists, or worrying about things you can’t control, cognitive shuffling offers a way to break that cycle.
It’s also useful for anyone dealing with stress or anxiety that makes it hard to wind down. Because the exercise is emotionally neutral, it doesn’t trigger the kind of heightened alertness that keeps you awake.

And unlike some sleep aids, cognitive shuffling has no side effects. It’s free, requires no equipment, and you can do it anywhere.
Tips for Getting Started
If you’re new to cognitive shuffling, here are a few tips to make it easier:
- Choose simple words: Start with shorter, neutral words like “table” or “piano” until you get the hang of it.
- Don’t overthink it: The images don’t need to be vivid or detailed. A quick mental flash of each object is enough.
- Be patient: Like any new habit, it might take a few nights before it feels natural.
- Use it consistently: The more you practice, the easier it becomes to slip into this mental state.
Why Random Thoughts Help You Sleep
One of the most fascinating aspects of cognitive shuffling is how closely it mirrors what your brain does naturally as you fall asleep. Research shows that as you transition from wakefulness to sleep, your thoughts become more fragmented and less logical.
By intentionally creating this kind of mental randomness, you’re essentially giving your brain permission to let go of structured thinking. You’re signaling that it’s safe to stop problem-solving and start shutting down for the night.
This is why cognitive shuffling feels different from other relaxation techniques. Instead of trying to clear your mind completely—which can be frustrating and counterproductive—you’re gently guiding it toward the kind of thinking that naturally precedes sleep.
A Simple Tool for Better Sleep
Cognitive shuffling won’t cure chronic insomnia or replace medical treatment for serious sleep disorders. But for many people struggling with occasional sleeplessness driven by stress or overthinking, it offers a practical, science-backed solution.

It’s a reminder that sometimes the best way to quiet your mind isn’t to fight your thoughts head-on, but to redirect them somewhere harmless and boring. Somewhere that doesn’t matter.
Next time you find yourself staring at the ceiling, skip the sheep and try shuffling instead. Your brain might just thank you for it.
