Cognitive Shuffle: The Simple Sleep Technique To Help You Fall Asleep Faster

Sleep is becoming an increasingly elusive beast. Research shows that nearly half of the UK population struggles to fall asleep at least once a month, with 36 per cent experiencing that very specific frustration at least once a week. If you’re one of them, may we suggest the “cognitive shuffle”?

While it might sound like a niche dance routine, the cognitive shuffle is actually a pre-sleep method which helps to encourage the brain into the calm, lucid state that precedes dropping off into the land of nod. “Sleep researchers have found that, as people fall asleep, they often experience visual images and ‘micro-dreams’ [which] may help them fall asleep,” the cognitive scientist behind the technique, Luc Beaudoin, says. “In contrast, continuing to think in a verbal, analytic, problem-solving mode can delay sleep onset.”

Since modern life is so stimulating – and we are so often in a high state of alertness – it can be tricky to move out of this mode and assist our brains in switching off for the night. What cognitive shuffling does is scramble the thoughts – as you focus on picturing a sequence of random objects in your mind – so that the brain cannot make sense of them, and therefore worry and anxieties are kept at bay.

These scrambled thoughts not only seem to trick the brain’s sleep regulators into thinking it’s time to fall asleep, but Beaudoin also argues that it distracts the brain from the worries at hand. Another reason this technique works, he says, is because the brain has evolved to constantly be alert to potential danger. When it checks if it’s safe to fall asleep at night – and its cortex doesn’t seem to be weighing up perceived dangers – it’s time to relax and fall into slumber. It is an excellent trick to try if you find yourself anxiously reliving embarrassing moments from the day, or worrying about the fact you forgot to call your parents.

Unlike counting sheep, which can actually trigger more worries due to the mundanity of the exercise, the cognitive shuffle, Beaudoin explains, “gives your brain just enough toys to play with, but not enough coherent information to stir executive functioning”. So, how do you do it? Your simple five-step guide is below.

  1. Pick a letter at random.
  2. Visualise a word that starts with that letter, ensuring that it is emotionally neutral and consists of at least five letters. Slowly spell it out in your mind.
  3. For each letter of the word, think of new words that start with that letter. For example, if you chose “bottle”, you might picture a broomstick, bin, bat or ball. Beaudoin recommends pausing and imagining each word, instead of racing through them.
  4. Once you’ve exhausted your letter, move onto the next letter of the word and do the same.
  5. Continue until you fall asleep, which should take no longer than 15 minutes.
