There’s a good chance that when you woke up this morning, your first thought was to go back to bed. But it’s also likely that you had so many obligations pulling you out from under the covers—work to do, food to cook, friends to see—that you started your day, even if you didn’t get your seven to eight hours of recommended shuteye.
It’s common to try to cram more waking hours into each day. About half of people worldwide get less than six hours a night, according to the Guardian.
