Without sleep, a vicious cycle takes place. Because your sense of control is weakened by a lack of sleep, the more tired you are, the harder it is to get yourself to go to bed, and the more tempting it is to just stay where you are and watch one more episode of Homeland. Your ability to inhibit your YouTube binge-watching habit or to stop yourself from checking your phone evaporates. You’re also much more likely to eat an entire pint of ice cream at 11:00 P.M., when you’re tired, than at 9:00 A.M., when you’re fresh. Our bad habits are exacerbated by insufficient sleep.
