Zhang Chaoyang, CEO of Sohu, said in an interview recently that he “only need to sleep for four hours every day, and sleep less and sleep well”. Moreover, these four hours are not continuous sleep, but wake up after two hours of sleep at night, and then sleep for another two hours after doing something else. As soon as this statement was made, it immediately aroused heated discussion.
on August 10, according to media reports, foreign websites sorted out the information in Mason Cary’s series of books, and combined with the information published on the Internet, made a sleep map of 50 famous people. The 50 celebrities are mainly from business, politics, entertainment, fashion, media, art, religion, sports and other industries.
the results show that most celebrities are far from enough sleep time, and their sleep habits are also very different. American president Donald Trump claims that he only sleeps three hours a day.
celebrities’ work tasks are heavy, their daily work and rest are relatively compact, and the corresponding sleep time is also compressed. Of the 50 celebrities, few are able to sleep for eight hours. Business people, politicians and sports have a shorter average sleep time, perhaps because of the need to keep in good condition when they are on camera, and the entertainment industry sleeps more than those in other industries.
Microsoft co-founder Bill Gates has a very regular sleep habit. He goes to bed at 12 o’clock every night and wakes up at 7 o’clock in the morning. Compared with the strange work and rest of many celebrities, gates basically follows the normal biological clock.
dozens of business people, such as Richard Branson, founder of Virgin Group and Elon Musk, CEO of Tesla, sleep between five and seven hours a day.
among the 50 celebrities, “hell Chef” Gordon Ramsay and trump have the shortest sleep time. Both of them like to work before going to bed and sleep only about three hours a day.
previously, according to reports from us websites,, and other media, trump got up at 5:30 every morning and began to make phone calls half an hour after he got up. CNN also revealed that unlike most Americans, the president doesn’t wake up with coffee or breakfast, and occasionally has bacon and eggs.
what’s more, trump thinks that sleeping only three hours a night is a secret of success. He once said that how can people who sleep 12 to 14 hours a day compete with those who sleep three to four hours?
of course, not all celebrities believe that the less sleep, the better. Ariana Huffington, the founder of the company, has always advocated enough sleep, and her sleep time has reached 8 hours. Tiger Woods, a famous golfer, sleeps 8.5 hours a day. Among the 50 celebrities, Greta Sandberg, a 17-year-old Swedish environmental girl, sleeps the longest. She sleeps about nine hours a day, which is in line with her age group’s sleep.
some people are energetic in the morning, while others are more suitable for night fighting. This difference in work and rest is also reflected in the sleep map of these 50 celebrities. Most people go to sleep between 11:00 p.m. and 1:00 a.m., and wake up between 5:00 and 8:00 a.m. But there are many exceptions.
actor mark Walberg is the “woodpecker” of 50 celebrities. When conditions permit, he usually goes to bed from 7:30 to 8:00 p.m., gets up at 2:30 a.m., and then begins to pray and make breakfast.
the typical owl who goes to bed late and gets up late is Mark Zuckerberg, CEO of Facebook. He usually brushes his Facebook from 11:00 p.m. to 3:00 a.m., and then goes to bed from 3:00 p.m. to 8:00 a.m. Whether it’s time to go to bed or wake up, Zuckerberg’s work and rest fall into the late category. Coincidentally, his work and rest fit perfectly with Winston Churchill, the former British Prime Minister.
the most peculiar work and rest time is in the sports world. Footballer Cristiano Ronaldo and the late professional basketball player Kobe Bryant wake up in the middle of their sleep to train and then go back to sleep. Ronaldo has five naps a day, each about 1.5 hours. Although the sleep map shows that Kobe’s sleep time is from 11:00 p.m. to 5:00 a.m., within these six hours, Kobe still needs to get up for training or exercise for two hours, and then go back to bed.
David Dinges, a professor of psychology at the University of Pennsylvania and an authoritative sleep researcher in the United States, believes that in fact, most of us need about 8 hours of sleep every day to ensure that we can make the best use of our abilities. He also admits that less than 5% of the world’s people are born short sleepers, and they can actually sleep four to five hours a night, or less.
Dinges also explained that even those who boast that they don’t need much sleep may underestimate their sleep time. Most people who sleep less at night tend to avoid fatigue by catching up during the day – for example, many busy executives may rest on the way to a flight or meeting. “They take naps a lot,” Dinges says
