People who love to stay up late are smarter?

  Everyone has their own work and rest preferences, and this preference has been shown to be genetic to a certain extent. Therefore, many scientists have been obsessed with ascertaining its correlation with cognitive ability.
  Numerous previous studies have shown that young, healthy night owls tend to perform better than their lark counterparts on tests of intelligence—specifically, they have better short-term memory (STM), Emotional intelligence is higher, and the language intelligence level of female “night owls” is more prominent.
  Is this really true? The situation is far more complicated than imagined. A team of cognitive neuroscientists at the University of Ottawa in Canada reinvited 61 healthy adults to participate in the observation. The researchers collected information on their daily routines and asked everyone to choose “the most awake time of the day” to participate in cognitive ability tests. The test measures subjects’ cognitive abilities in three areas: reasoning, verbal ability, and short-term memory.
  The results show that memory ability has no relationship with a person’s work and rest habits; for men and women, the relationship between comprehensive cognitive level and work and rest is similar.
  Some observations are consistent with previous observations, for example, higher verbal intelligence is indeed related to “late sleep”. But at the same time, the researchers also had a contradictory finding – it was also associated with “morning up early.”
  ”Once we controlled for the variables ‘bedtime’ and ‘age,’ we found the opposite—morning people tended to have superior verbal skills,” said Stuart Fogel, director of the university’s Sleep Research Laboratory. However, in reality, very few people can stay up late for a long time and wake up regularly at the same time.
  The researchers said that this study shows that the level of a person’s intelligence cannot simply be equated with his work and rest preferences. “Other factors related to the internal biological clock (circadian rhythm) may also affect cognitive ability.” The
  combination of preference and internality, and the final behavioral rules of work and rest, are defined as chronotypes.
  In recent years, more and more scholars have begun to advocate a view that the binary division of “lark” and “night owl” is not enough to summarize all types of work and rest.
  Larks, for example, tend to be most active in the morning in terms of arousal and energy levels, drop to a moderate level by noon, and then hit rock bottom at night; in contrast, night owls tend to be most tired in the morning, But the energy level gradually increased over time until it peaked in the middle of the night.
  The study also pointed out that with the change of age, the type of people’s work and rest will also change-before the age of 10, people tend to “lark” style of work and rest, and then become “night owls” in adolescence and youth, and reach 60 Around the age of 10, it returns to the sleep pattern of the 10-year-old.
  The researchers suggested that one hour before going to bed, start to limit the light, stay away from TV and mobile phones; correspondingly, after the bell rings, immediately accept the “baptism” of sunlight to stop the secretion of melatonin. In addition, people who want to rest early should avoid stimulating activities at night, such as exercising and eating.
  ”In any case, as far as the status quo is concerned, ‘the early bird does catch the worm’.” The researcher said with a smile.
