Is there a relationship between IQ and sleep time?

There is a relationship between IQ and sleep, but I think it is because of quality sleep that people have a high IQ. Research on developmental psychology has shown that adequate and quality sleep can promote children's growth and development, especially the development of the central nervous system, and at the same time, the central nervous system can also rest enough and restore good functional status through good sleep. Total sleep duration, especially at night, may affect preschool children's attention span and cognitive abilities such as working memory.

I think sleep has a certain relationship with people's IQ, generally speaking, under normal sleep conditions, that is, to ensure natural sleep time, people can exert their normal IQ ability. ‍‍

If it is an adult, it doesn't matter if you feel it, lack of sleep will only lead to decreased immunity, neurasthenia, appetite, ** deterioration and so on, some physical and mental health has a great impact, and the IQ of adults is rich in knowledge and experience is slowly accumulated, not that it is gone without sleeping. If you are a child, due to lack of sleep, it is difficult to concentrate, memory loss, slow thinking, etc., IQ will have a little impact.

Sleep time is inversely proportional to sleep quality, which means that the better the quality of sleep, the less total sleep time is needed. IQ is a function of the brain, and sleep time is a function of the autonomic nerves, although both are influenced by genes. It can be proven that if you don't sleep enough, it will definitely have a great impact on a person's cognitive function, that's for sure. ‍‍

I think there is a relationship between IQ and sleep, because with quality sleep, people have a high IQ. ‍‍

The human brain, like other organs, must be tense and relaxed, excited and inhibited in order to carry out intellectual activities normally. Fatigue caused by using the brain during the day, relaxation of the muscles of the whole body during sleep at night, various metabolism decreases, and body temperature decreases, which is conducive to the synthesis of nutrients in the body, and the accumulation of a large amount of oxygen and other nutrients can be the material basis for the next day's mental exercise. During sleep, the need for glucose in brain tissue decreases, and metabolites are carried away with the blood circulation, which helps prevent the function of nerve cells from declining.

Sleep and IQ are related to other factors, for example, people with high IQ generally take greater responsibility in society, and the greater the responsibility, the greater the workload, although the time lost through efficient work can be reduced, but it often brings a greater amount of work, therefore, sleep less, simply put, is the ability to work more.

Sleep is an important part of people's lives, sleep not only has an important impact on physical health, but also affects people's mental health and cognitive function (IQ). With the increase of age, the sleep quality of the elderly decreases, which can induce various chronic diseases and affect the mental health and quality of life of the elderly. Memory impairment in older adults is related to sleep, and improving sleep can promote memory.

Some studies have found that the elderly with chronic insomnia have impaired cognitive functions such as memory span, attention allocation, and executive ability. In conclusion, sleep not only has an important impact on physical health, but also affects people's mental health and cognitive function. Sleep quality and duration are the guarantee of good cognitive function. ‍‍

It is not inevitable that people with high IQ will sleep less, and there may be people who have more excitatory neurosubstances. Whether people who sleep less have a high IQ is not necessarily, but not sleeping enough will definitely have a great impact on cognitive function, so it is better to sleep enough according to your own feelings, and even if smart people sleep less, it does not mean that you can become smart if you sleep less. ‍‍

I don't think it matters, otherwise my IQ would be negative according to my strength to stay up late every day! Besides, Edison only slept four hours a day, didn't he still have superior intelligence?

One-third of a person's life is spent sleeping. Lack of sleep or too much sleep can have a negative impact on mental development; Normal sleep is a physiological phenomenon in which the human body relieves fatigue, restores physical and mental strength, and is conducive to work and study.

Sleep studies of adolescents and school-age children have shown that sleep quality and duration are highly correlated with poor academic performance, teacher-reported behavioral problems, and general IQ.

IQ has nothing to do with work and rest timeScientists' research seems to suggest that people who go to bed later have an intellectual advantage, but another possibility that has been overlooked is that people with high intelligence may be more comfortable with the rhythm of sleeping late and waking up later. London psychologist Jin Zezhe Zhe, the study of intelligence gives a preliminary explanation for this:

Kim also conducted a longitudinal study of American adolescents that measured the intelligence level of 15,197 students between the ages of 18 and 28 in 1994 and 1995, as well as their schedules in 2001 and 2002.

The results of this study show that IQ does affect work and rest arrangements, and on the other hand, it also reveals that the direct effect of this effect is very small. Therefore, as for the relationship between sleeping late and intelligence, to be precise, it is only that intelligent people are better at night activities, and there are more people with high IQ in "owls" than the average person, but this conclusion is not necessarily true.

It has been scientifically proven that Einstein IQ 160 sleeps 3-4 hours a day, and ordinary people should still maintain 8 hours of sleep is the best!

Scientists have found that people who go to bed late and wake up late are smarter and have better memory than those who go to bed early and wake up early, which means that people who are nocturnal are smarter than those who are active during the day.

Truth: Some people wake up early and go to bed early, just like larks, and they are as industrious as larks; There are also people who wake up late and go to bed late, as weird as owls. Psychologists have long noticed that different people have different circadian rhythms, and smart people are more attuned to nightlife:

In 2009, Kim applied his intelligence hypothesis to circadian rhythms, providing a preliminary explanation for why smart people are better suited to nightlife.

In ancient environments, humans were more likely to be active during the day, working at sunrise and resting at sunset. In contrast, night can be said to be an evolutionarily novel environment. Kanazawa believes that since night is an evolutionarily new environment, intelligent people are better at moving in this environment.

IQ Profile:

Intelligence quotient, also known as intelligence quotient, is an index of personal intelligence test scores compared with the scores of subjects of the same age, and is a measure of individual intelligence.

It may also be because brain cells are active, so there is less sleep.

What kind of J8 theory is this?

Albert Einstein, a great scientist with an IQ of 160 or more, slept only 1 to 3 hours a day; For every 4 hours that da Vinci worked, he slept for 15 minutes, and only slept about 1 and a half hours a day; The Prime Minister also sleeps very little, only about three or four hours a day, but he has a lot of energy to work. Therefore, there is an opinion that "the higher the IQ, the shorter the sleep time". Is this true?

Zhang Yonghua, president of Hangzhou Seventh People's Hospital, believes that there is some truth in this statement, because people with high IQ tend to have more excitatory neurosubstances, active thinking, inspiration emerges at any time, and the long time of excitement requires a relatively short amount of sleep. However, he especially reminded that there is another group of people who suffer from mild mania, and the early manifestations are also shortened sleep time, very active thinking, a lot of inspiration, a strong memory, and even a memory, and they are very efficient and energetic. "I've received such a patient, who only sleeps three or four hours a day, who feels very good about himself, who is doing very well in business, who is very energetic, who can read a book in one night, but who is actually a mild mania. ”

Not necessarily, from person to person, from time to time, from event to thing, different needs are expressed in different ways.

Congratulations, you got it right. It's true.

It's okay, it's different for everyone.

People who sleep less are smarter for a period of time than people who get enough sleep, and they are more vigilant or have more active brain cells, but this is only temporary, and in the long run, people who sleep less will have fewer brain cells later in life than people who get enough sleep.

Is it true that sleep deprivation makes people stupid?
