Sleep deprivation is no joke.
Even moderate fatigue can hit you as hard as alcohol intoxication, according to a helpful chart from the Harvard Business Review.
However, many top executives and leaders seem to swear by skimping on shut eye.
Some of them might be part of the “sleepless elite.” Others are probably just good at masking the effects of exhaustion.
Unless you’re one of those lucky people who doesn’t get tired, your best bet is to avoid emulating these individuals when it comes to your sleep routine:
Twitter cofounder and CEO and Square CEO and founder Jack Dorsey sleeps four to six hours a night
Being at the head of two exciting tech startups doesn’t leave too much time for rest. In 2011, Dorsey told Kara Swisher that he was spending eight to 10 hours a day at Square, and eight to 10 hours a day at Twitter.
That left him somewhere around four to six hours a night to sleep, possibly less when travel time is factored in. He still manages to get up at 5:30 every morning to take a jog.
President Donald Trump gets three to four hours of sleep a night
“How does somebody that’s sleeping 12 and 14 hours a day compete with someone that’s sleeping three or four?” he asked the Daily News.
PepsiCo Chairperson and CEO Indra Nooyi gets four hours of shut eye each night
She’s no stranger to long hours, having worked the graveyard shift as a receptionist while getting her Master’s at Yale.
