In one study, scientists instructed insomniacs to get into bed only when they were tired. If they couldn’t fall asleep, they were told to sit in a different room until they became sleepy. Over time, subjects began to associate the context of their bed with the action of sleeping, and it became easier to quickly fall asleep when they climbed in bed. Their brains learned that sleeping — not browsing on their phones, not watching television, not staring at the clock — was the only action that happened in that room.
