Here’s the thing: I’m tired. Because no matter how much we are told we need more shuteye, we’re still not getting enough. In fact, a good night’s sleep is such a precious commodity that in the past three months alone, more than 20 books on the subject have been published. We’re officially knackered, and brands are racing to help us rest better: the less we sleep, the more we’re willing to pay to try. While we lie awake counting sheep, businesses are counting the money, turning sleep into a global industry that will be worth an estimated £60bn by 2022, according to Persistence Market Research.
