It is said that geniuses are all night owls, are they reliable?

  We usually call people who like to sleep late as “night owls.” The so-called night owls are also another name for owls. Coincidentally, in English, those who are spirited at night are also called “owls in the night.”
  Among the various chicken soup essays and inspirational success studies, those life winners with super IQ are almost all night owls, smarter and more energetic than ordinary people. For example, at Harvard University, where students gather, the library is still brightly lit at 4 am, Bill Gates sleeps only 4 hours a day, and so on.
  But in fact, are night owls really smarter? For this issue, cognitive psychologists and biologists have conducted years of research, but there is still no clear, black or white conclusion. According to the existing research results, we can be sure that “people who stay up late are not necessarily smart, but many smart people prefer to stay up late.” At
  this point, some people may be wondering, not that staying up late will lead to lack of sleep. Does it cause depression, inattention, decreased thinking, and a series of diseases? Why would smart people choose such an unhealthy lifestyle? In this regard, Matthew Walker, head of the Sleep Research Center at the University of California, Berkeley, explained: Night owls do not necessarily lack sleep because they sleep late and get up late. This unique routine is largely genetically determined. of. Among all human beings, about 40% of humans belong to the “early to bed and early to rise” type, while about 30% are of the “late to bed and late to rise” type.
  A study published in Nature Communications in 2016 conducted a genome-wide association analysis on samples of more than 100,000 people regarding sleep types, and screened 12 gene loci related to sleep types. They are mostly related to the central nervous system, visual system and fear-alertness-related information processing, and may participate in the regulation mechanism of circadian rhythm and light sensitivity, thereby affecting our sleep type. What’s more interesting is that among the 30% “sleeping late” people, there are about 1% to 5% of people called “short sleepers”. Because they have a rare mutation in their genes, their necessary sleep time is as short as 5 to 6 hours, which is 1 to 2 hours shorter than that of ordinary people.
  Of course, belonging to the “late to bed and late rise” crowd does not mean that you are smarter than others, but many smart people with high IQ do indeed belong to the “late to bed and late rise” crowd. Facebook founder Mark Zuckerberg admitted in an interview that he was never an “early riser”. He usually gets up at around 8:30 in the morning. In contrast, he is used to working late at night. And Reddit co-founder Alexis Ohanian and other successful people with extremely high IQ and energetic staying up late are likely to belong to the group of “short sleepers”.
  The Radboud University in the Netherlands published a research paper in “Scientific Reports”. The author interviewed 1172 adult members of the Mensa Club in Germany (with an IQ of no less than 130), and conducted research on their work and life schedules. Detailed analysis. Researchers found that during the working day, most of Mensa’s high IQ geniuses are of the “sleep late and wake up late” type, but their total working hours are longer than those of the general population. On non-working days, they are still the typical ones who go to bed late and get up late. The only difference is that they spend significantly more time in bed. Next, the researchers analyzed the daily routines and work schedules of these Mensa club members and found that their common characteristics are the “three nights”: work starts late, falls asleep late, and wakes up late.
  This shows that different work schedules are likely to be one of the reasons why people with high IQs are used to going to bed late.
  As for why people with high IQ started working late, the author provides a possible speculation: This may be because people with high IQ usually engage in creative and management work in indoor enclosed environments. Compared with people who work outdoors such as agriculture and construction, they usually go to work later during the day, but may need to work even later at night.
  Seeing this, you may already understand that smart people like to stay up late, which is probably determined by the “biological clock” in the body and their working characteristics. And other studies have shown that night owls like to work at night, which is not only a natural routine of work and rest, but also a necessary condition for their ability to work fully-in the evening hours, night owls’ thinking, physical ability and other abilities will reach a level The highest peak.
  The University of Alberta in Canada once conducted a control experiment on the physical functions of people who “sleep late and get up late” and “early to bed and get up early”. Due to the limited number of volunteers participating in this experiment, it may affect the universality of the data for the entire population, but the researchers still found some interesting phenomena from the data: the body strength of people who go to bed early and wake up early is at noon (13:00). ) Is the strongest, and then gradually weakens; while the excitability of the cerebral motor cortex is strongest at 9 o’clock in the morning, and is much higher than that of people who go to bed late and wake up late, but this indicator will continue to decrease over time, until the weakest at night. But overall, these two indicators have not changed much in one day. On the contrary, the physical strength of night owls and the excitability of the nervous system change very obviously in different periods. Muscle strength was weakest at 9:00 in the morning, but gradually increased over time, and was significantly stronger at 17:00 in the evening than at 9:00 in the morning, and reached the strongest at 21:00 at night. At the same time, the excitability of the motor cortex of night owls also increased, and it also reached a peak at 21:00. It is worth noting that there is almost no difference in muscle strength and brain excitability in the evening (17:00) between the two sleep patterns. However, as night falls, by 21:00, the muscle strength and motor cortex excitability of night owls are much higher than those of people who go to bed and wake up early.
  This kind of inspiration is repeated, the work efficiency is super high, and the night work hours that make people stay in a state of ecstasy for a long time are called “hacker time” by Silicon Valley Internet people. “Brighter computer screens, less noise, and greetings with others disappear without a trace. You can adjust yourself to energy-saving mode except for the parts created by your mind.” Famous Apple technical engineer and inventor of Finder Bruce Huo En recalled, “Programmers like to make some radical and bold changes to computer programs in the middle of the night, so that even if the system crashes, they can use the time before work the next day to make remedies without being noticed by the supervisor. ”
  Seeing this, many students who go to bed and get up early are definitely not convinced. Has my good habit of going to bed and getting up early has become evidence of my low IQ? Don’t be restless. Although work and rest time and human ability are related variables, there is no strict direct relationship between them. Many smart people stay up late, go to bed late and wake up late, but this does not mean that early to bed and early to rise are inferior. Second, despite the genetic influence of sleep type, it is difficult to rule out the influence of occupational choice on sleep patterns.
  Finally, remind everyone that smart people tend to sleep late, rather than staying up late to become smart. If you do not get enough sleep or sleep irregularly because of staying up late, not only will it not help your thinking and cognition, but it will also harm your health.
