For one, when you’re conducting a sleep survey, you have to make sure you’re asking the right questions, as Jim Horne, Ph.D., professor emeritus of psychophysiology at Loughborough University in England and the author of Sleeplessness , explains. “If you ask someone: ‘Would you like to get more sleep?’ the answer is probably yes,” Horne says. “Of course they want more sleep. The better question is how many people would forego what they do when they’re awake to sleep more?” It’s like asking someone if they’d like to live in a bigger house or have more money. The answer is probably sure, why not? But it doesn’t mean there’s anything wrong with their current house or bank account.
