Microsoft CEO Satya Nadella doesn’t skimp on sleep

There’s a perception that most successful people are early risers. Apple CEO Tim Cook and Disney CEO Bob Iger both wake up at 4:30 am, for example. That’s not the case for Satya Nadella — the Microsoft CEO usually wakes up at 7 am, he said during a rapid-fire Q&A with ABC.

Nadella also said he gets eight hours of sleep, which is likely more than most CEOs.

In 2011, for instance, Square CEO and Twitter co-founder Jack Dorsey told Kara Swisher that he would spend eight to 10 hours a day at Twitter, and eight to 10 hours a day at Square. That would leave him with between four and six hours of sleep, since he said he gets up at 5:30 am to jog each morning.

The Guardian reported that Yahoo CEO Marissa Mayer only needs between four and six hours of sleep each night.
