This Is How Much Successful CEOs Actually Sleep

Genevieve Fish

There never seem to be enough hours in the day, so sleeping less—even by just a couple of hours—to maximize your time can feel like a formula for success. Yet doctors like Dr. Frank Lipman continue to argue that people function best with seven hours of sleep. “Only about five percent of the population can get by just fine on six hours of sleep,” says Ying-Hui Fu, a professor of neurology at the University of California, San Francisco. There’s a reason sleep deprivation used to be a torture tactic: At its best, less sleep causes fatigue, irritability, and difficulty concentrating, and at its worst, it can cause disorientation, apathy, and hallucinations. So why is it that more than 83.6 million people aren’t getting enough sleep? And are today’s intellectual elite following suit?

Curious, we decided to examine the most highly functional, highly successful businesspeople of the modern age (think Elon Musk, Arianna Huffington, and Marissa Mayer) to determine what really works. Ready for a dose of reality? Here’s how many hours today’s top-performing CEOs actually sleep.
