The mentality that hard work should be prioritised over sleep for the reward of success is fast becoming an outdated approach, given the research that has emerged on sleep – along with nutrition and exercise – and its critical role to our overall health.
The American Academy of Sleep Medicine advises that seven hours is the minimum amount of sleep recommended for adults, which is not achieved by more than a third of Americans.
"Our Consensus Panel found that sleeping six or fewer hours per night is inadequate to sustain health and safety in adults, and agreed that seven or more hours of sleep per night is recommended for all healthy adults," says Dr Nathaniel F Watson.
It’s also ideal to get into a rhythm when it comes to sleep patterns, which is why many of the world’s top business leaders have a consistent routine in place.
"The recommendation right now is to get consistent sleep. Whether it’s the weekend or a weekday, keep doing that consistently," explains Matthew Walker, author of the international bestselling book Why We Sleep and Professor of Neuroscience at the University of California, Berkeley.
He goes on to say that "sleep bulimia", where you make up for lost sleep during the week on the weekends, is not a solution.
"Unfortunately, sleep is not like a credit system. Sleep is not like the bank in the sense that you can’t accumulate a debt and then hope to pay it off at a later point in time."
The sleeping habits of highly successful people

In the morning, rather than check her phone, Winfrey brushes her teeth and cares for her dogs before heading to her home gym.
"I have never set an alarm, I don’t believe in them. My first thought in the morning is, ‘Oh, I’m alive. Thank you!’" she told The Hollywood Reporter.
"I usually get into bed and I have volumes and volumes of gratitude journals by the side of my bed. The last thing I do before I go to sleep is write five things that gave me great pleasure or that I was grateful for."
This routine is most likely inspired by the advice of her sleep doctor Dr Michael Breus, who believes: "The secret to sleep is to pay attention to what you’re doing in those precious hours before bedtime."

"Anything that’s going to be really mentally challenging is a 10am meeting," he said. "Because by 5pm I’m like, ‘I can’t think more about this issue today. Let’s try this again tomorrow at 10am.’"
His mornings are spent doing leisurely activities like reading the newspaper and drinking coffee with his family.

The international media mogul and author of The Sleep Revolution learned the hard way the value of sleep after experiencing a collapse.
"I fainted from exhaustion. I hit my head on my desk. I broke my cheekbone, I got five stitches on my right eye. And I began the journey of rediscovering the value of sleep," she explained in her 2010 TED Talk ‘How to succeed? Get more sleep’.
Huffington believes it’s the key to a more productive, more inspired and joyful life. "We’re living as a culture under the collective delusion that in order to succeed we have to burn out along the way," she told CNBC.
Achieving eight hours of sleep, her bedtime routine requires a certain level of discipline.
"The transition I practise involves turning off all the devices and gently escorting them out of my bedroom. Then I’ll only read a physical book before bed – no screens – and books that have nothing to do with work."
The Founder and CEO of ecommerce company Shopify is an advocate for maintaining a work–life balance and sticking to the recommended hours of sleep.
"I’ve never worked through a night. The only times I worked more than 40 hours in a week was when I had the burning desire to do so. I need 8ish hours of sleep a night. Same with everybody else, whether we admit it or not," he tweeted.
"I’m home at 5.30pm every evening. I don’t travel on the weekend. I play video games alone, with my friends and, increasingly, with my kids. My job is incredible, but it’s also just a job. Family and personal health rank higher in my priority list."
This balanced perspective gives the CEO plenty of time for sleep and rest.
