Have trouble falling or staying asleep? Try cognitive shuffling.
Start by thinking of a word something neutral or positive, like the word house. Then, think of as many words as you can that start with the first letter: horse, harmonica, honey. Try to picture each object or idea for 5 to 15 seconds, maybe even imagining a scene with yourself in it. (Youre riding a horse. ... Youre playing the harmonica. ... Youre harvesting honey!)
Beaudoin recommends against finding connections between the words. Just let the images wash over you. Whenever you find yourself having a hard time coming up with another word, move on to the next letter in this case, o owls, oasis, ocean and so on. Come up with images for each letter in your original word until you fall asleep. If you run out of letters before you fall asleep, pick a new word.
Its hard to think of random material, but this little technique helps people, Beaudoin said. (He also developed an app called MySleepButton for people who want help with the technique.)
In addition to mimicking the kind of thinking that happens right before sleep, the method also requires a certain amount of brain power enough to interrupt the worrying or problem-solving that often keeps us awake.
