People can be roughly divided into "morning people" and "night people".
So what kind of people do we belong to?
The first person in Japanese health medicine is Kawasaki Kiyokang, who divides people into three types according to their physique: S-type, P-type and M-type. Details are as follows:
① morning type
For example, going to bed early at night and waking up at dawn is an "S-type person".
This type is characterized by hypertension and baldness in men. He has a big appetite and a thick neck. I am active and like to appear in public. Even if I have something on my mind, it's just a temporary depression, and I can completely forget it after a night's rest. Simply put, he is a cheerful person.
This type wakes up early in the morning and it is difficult to stay in bed after waking up.
② nocturnal type
It's okay to be extra energetic at night, but people who have trouble getting up early are "P-type people".
The characteristics of this type are just the opposite of S type, with low blood pressure and a tendency to gray hair. A thin neck won't make you fat if you eat more. Born with a bad stomach and a negative personality, he belongs to the thinking type. Can be said to be a gloomy person. Therefore, once you have something on your mind, you will always be depressed. Poor appearance, I am in a daze in the morning.
However, this type will feel refreshed at night and may be called "off-duty family".
Most people can be classified according to these two types, but there is actually another "M-type person".
③ Superman type
This type can maintain abundant energy in the morning and at night. I don't know when they will fall asleep, just like Superman.
Napoleon once said, "I only sleep for three hours every day."
This type, it is said that only 1 person out of 65438+ people.
From the above list, you should know exactly what kind of physique you belong to now.
Even without this detailed classification, everyone instinctively knows whether he is an owl or a lark-that is, a day worker or a night worker. Many people worry that they can't go to bed early, and then they can't get up early, which will affect their mood and work, so that they begin to blame themselves for not having the self-control to rest on time, and even feel anxious about it, which will affect their sleep.
In fact, you don't have to criticize yourself too much for staying up late, because Craig Venter, an American biologist, mentioned night genes in his book Decoding Life, explaining that some people like to stay up late and stay up late reading because night genes are at work in their bodies.
Moreover, when studying the Japanese sense of time, the NHK national life time survey has an interesting statistic. On the contrary, the "short sleep group" is more energetic, and the energy of the human body has almost nothing to do with sleep time. The "eight-hour sleep theory" is a big lie, and sleep time is related to age. There is no need to be stubborn, but force yourself to sleep eight hours a day.
Therefore, the next time you stay up late, don't be too sensitive to add pressure to your heart for no reason, just like Pavlov's conditioned reflex, correctly understand the night shift and treat it with a normal heart.

Research shows that owls are smarter than larks.
1In the autumn of 1999, psychologist Roberts of the University of Sydney in Australia cooperated with Kirona of the US Air Force Research Institute to recruit 400 recruits who had just been trained for 6 weeks. By measuring the circadian rhythm score, memory and agility of recruits, it is found that the more recruits get up early and go to bed early, the weaker their memory and agility are than their peers who get up late and go to bed late.
Therefore, Roberts and Kirona believe that people who get up late and go to bed late are smarter.
In 2007, researchers from Italy summarized the research of participants aged from 19 to 76, and found that owl-type people scored higher than lark-type people in all dimensions of creative thinking (fluency, flexibility, originality and leapfrogging), especially in originality.
In addition, a team led by Kyle Fabry, a psychologist at the University of Bologna, surveyed 1254 college students aged 18 to 30, and found that owls tend to think more about their right brain, which tends to be intuitive and comprehensive, while larks tend to think more about their left brain, which tends to be left brain. Generally speaking, creativity is more closely related to the right brain.
These facts mean that people who get up late and go to bed late have an intellectual advantage; In other words, people with high intelligence are more adapted to the physiological rhythm of getting up late and going to bed late.
In 2008, Jin Zezhe, a psychologist at the London School of Economics and Political Science, put forward his own opinion after synthesizing the views of early evolutionary psychologists, and adopted more environmental novelty indicators (including latitude, longitude and latitude-longitude distance) to determine the relationship between this factor and intelligence with 192 countries as samples. The results show that all indicators are positively correlated with intelligence. In 2009, Jin Zezhe applied his intelligence hypothesis to the circadian rhythm, initially explaining why smart people are more suitable for nightlife.
However, owls should not be too happy. After controlling various factors, the influence of IQ on circadian rhythm is greatly reduced, even to the point of being negligible. The regression coefficient of IQ to working hours is less than 1%, that is to say, if two people have different working hours, IQ can only explain the difference between their working hours by less than one ten thousandth. Therefore, on the one hand, this study shows that IQ does affect work and rest time, on the other hand, it also reveals that the direct effect of this influence is very small.
We should correctly understand the meaning of getting up late and going to bed late.
Although smart people are better at night activities or night owls, there are naturally more people with high IQ than the average person. However, this conclusion is not necessarily correct in turn. People who get up late and go to bed late may not have high IQ, because there are too many factors leading to getting up late and going to bed late. Given that the individual differences of circadian rhythm have a moderate degree of heredity, it may mean that larks can hardly become owls by adjusting their sleep time. Of course, it is even more impossible for them to improve their IQ by slowing down their physiological rhythm.
However, clever owls are easier to understand. Staying up late for a long time will make people's skin dark and rough, and their immunity will decline. In addition, sitting up late for a long time increases the possibility of early cardiovascular diseases, hypertension, stroke, diabetes and other diseases, and also leads to insomnia, forgetfulness, irritability, anxiety and other symptoms. Owl-type people should properly adjust their work and rest to lark-type for their health, otherwise they will only be smart without health, just like a vase without holes, but it is just a decoration with no practical value.

The topic of discussion today is staying up late. On the one hand, when you rule out staying up late, don't care too much about staying up late, which will bring you pressure, trouble and even anxiety. On the other hand, the most important thing is to remind everyone to lose themselves and be a morning person.
The morning type refers to those who insist on going to bed early at night and getting up at four or five in the morning. In order to stay happy in their busy lives and work, they get up early, listen to music, read books and listen to the radio.
Getting up early is worth three points, but in today's era, the advantage of "early risers" may be far above three points.
Jiang Xun, a famous painter, said with emotion when he was in his sixties: "Every morning, looking at the flowers from the twilight of dawn and sunrise, sitting in front of them seems to realize that there is still a long way to go in life. It is the old age, but the gray hair is also the brilliant flower of life." Prime working hours in Jiang Xun are always from 6 am to 9 am. So getting up early can help us understand life and find creativity.
It can be seen that getting up early can not only build a good mood for us, but also accelerate the inflow of ideas and improve work efficiency. Since relaxation is also a day, fatigue is also a day, so why not let yourself get up early, steal a few hours and have a good day easily?
Getting up early is a person's self-control ability and a habit of keeping healthy. You who get up early may not have impressive achievements, but you will never have a miserable life.
Franklin once said, "I have never seen a diligent and honest man get up early and complain about his bad fate." Owl, from tomorrow on, we will change into costumes and become larks singing euphemistic songs! Smart owl, I believe you will make the right choice!
