Researchers at Simon Fraser University have designed an iOS app to help people fall asleep. The app makes use of cognitive science to hijack thoughts so that the brain stops trying to make sense out of them, reports the International Business Times.

The app, mySleepButton, works by reading out a stream of random, unrelated things or scenes that people are asked to imagine. The app might suggest a user thinks of a baby, then a football game, then London, then a bird on a branch.
