“Inadequate sleep impairs brain functioning, including working memory and long-term memory, attention, decision-making, hand-eye coordination, calculation accuracy, logical reasoning, and creativity.20 People who’ve been awake for nineteen hours (say, woke up at 7 A.M. and now it’s 2 A.M.) are as impaired in their cognitive and motor functioning as a person who is legally intoxicated.21 People who’ve slept just four hours the previous night are similarly impaired, as are those who’ve slept six or fewer hours every night for the last two weeks. Anything you wouldn’t do drunk—drive, lead a work meeting, raise a child—don’t try it if you’ve been awake for nineteen hours, slept only four hours the previous night, or slept fewer than six hours every night for two weeks.”
