I quite agree with the study of biological clock.
People are in a rhythmic environment. In order to adapt to survival, we must extract some rhythm features to coordinate with the environment. The appearance of biological clock is the process and result of the interaction between human beings and the environment.
On the other hand, rhythm is one of the fundamental attributes of everything. There is nothing special about life.
The law of daily life generally refers to being able to follow the law of biological clock.
There are many kinds of biological clocks. The most important ones are sun clock (corresponding to the earth's rotation), Moon Clock (corresponding to the periodic motion of the moon, the star closest to the earth) and Year Clock.
As a result of our statistical research, we also found some rhythms. At present, the three rhythms of the human body, also known as human biological rhythms, are used the most. I am deeply interested in this, and in 1998, I also designed the human three-rhythm software. The three rhythms of the human body have a strong reference function, but there is no need to be superstitious. The result of statistical regression must be that many events are outside the curve. The development of things will be affected in various ways. Simply relying on a certain level of cognition, such as human rhythm, often affects people's grasp of the overall situation.

Scientists discovered the human biological clock gene 2001/01/2114: 37.

The abstract of the article published in Science on June 65438+ 10/month that scientists discovered the gene of human biological clock was published in advance. The figure 1 is a page. Genes that control the biological clock have been found in fruit flies, mice and other animals. However, there is no direct evidence that humans also have such genes to control the biological clock. A team of scientists led by Yin-HuiFu of the University of Utah in Salt Lake City first discovered the gene that controls the biological clock. If this gene mutates, you can get up four hours earlier when you wake up from sleep.
The research team investigated a large family with rare sleep time disorder syndrome. Members of this family woke up four hours early. The researchers focused on the end of chromosome 2, which may be the location of the sick gene. A base pair was found in the hPer2 gene of family members with abnormal sleep. JosephTakahashi, a geneticist at Northwestern University in Illinois, thinks this is the first example of a human biological clock gene. As the first step in developing drugs that can speed up or slow down the clock, Fu and his team are looking for molecules that can interact with hPer2-related proteins.
Science Magazine: Animal Skin Biological Clock 2001April 17 09:28 Xinhuanet.
Xinhuanet Beijing April 17 Specials Professor Okamura of Kobe University in Japan published a paper in the American magazine Science on June 13, saying that there is a biological clock in mammalian skin tissue, and it is synchronized with the biological clock in the brain. This discovery may be used to diagnose various diseases caused by biological clock disorder.
Scientists have found in experiments on mice that there are a large number of biological clock genes in fibroblasts of mouse skin adhesion tissue. He called the biological clock in the hypothalamus of the brain "mother clock" and the biological clock in tissues and cells such as skin "child clock". He also found that the child clock and the mother clock move together, and the mechanism of action is the same. It is considered that the biological clock structure and mechanism of various mammals, including humans, are roughly the same.
Professor Okamura said that this discovery should be further studied to reveal the mechanism that the mother clock controls the child clock and why the child clock gene exists. (End)
It was found that the human body made protein 2000/12/1408: 41xinhuanet according to the rising and falling of the sun.
Xinhua News Agency, Geneva, 65438+February 13 Recently, a group of researchers from the Biology Department of Geneva University confirmed that almost all cells in human organs have a second biological clock, which makes protein according to the rise and fall of the sun.
The research team led by Professor Yuli Hibler will publish a report on the second biological clock of the liver and its influence on medication in the near future.
The research team said that if an experimental mouse is forced to eat during the day instead of at night for several days, its liver biological clock will gradually slow down the cycle of producing detoxification enzymes to help digestion to adapt to the new schedule.
The reversal of the program will only happen in the liver, kidney and pancreas, because the main biological clock of the human body still runs according to the original rhythm.
Scientists increasingly believe that the master biological clock regulates the time of the second biological clock through some "chemical and hormonal signals".
In addition, scientists also pointed out that adrenocortical hormone also has the ability to reverse the normal activities of other organs, such as the heart, pancreas and kidney, but it can not have the slightest impact on the role of the main biological clock.

Everything in the universe has its own unique laws: morning glory blooms at dawn; Cordate telosma exudes fragrance in the moonlight; Bats sleep well during the day and are active at night; The cock crows at dawn, which is a rhythmic and regular physiological phenomenon and is controlled by the "biological clock" in the body.
Humans are no exception, and they also have biological clocks in their bodies. Humans can be roughly divided into three types: daytime type, night type and intermediate type. The Japanese pattern is manifested in the early morning and early morning, full of energy, and the best memory comprehension. For example, mathematician Chen Jingrun and writer Yao are used to working at two or three o'clock in the morning, which is very efficient. Brain cells at night are particularly excited and highly concentrated at night. For example, the French writer Flaubert used to write all night. Over time, his all-night light became the beacon light for boatmen on the Seine. The intermediate type is between the first two, and the study and work effect is particularly good in the morning and evening. For example, the poet Ai Qing, in these two periods, literary thoughts blossomed.
It is by using the biological clock that these celebrities can give full play to their talents. We should remind middle school students that there are two reasons for the formation of their biological clocks: both innate factors and the long-term development of the acquired working environment. In fact, people's biological clock can be adjusted. In order to adapt to the time difference around the world, diplomats and athletes have to adjust their biological clocks artificially and strive to be at their best when they need physical strength and energy most.
Grade three students are in a comfortable period of physical and mental development. No matter what the biological clock is, I think we should get such a * * * knowledge: start studying at eight o'clock in the morning, study for four hours at a time, wash and eat at school after six o'clock, and wait until the math, English and Chinese teachers take turns to guide and review systematically in the morning, so I'm afraid I won't be able to bear to fall asleep; If you overemphasize the characteristics of the night, you must review all night, and you will sleep when the sun rises. So I don't advocate that middle school students' friends over-emphasize their own clock types. Let's try this: live two hours earlier than the normal day and night, but sleep more in the morning to ensure that you are full of energy and energy during the day. If you take a nap in the middle of the afternoon and then take a nap after school in the afternoon, then divide the time into four best periods: morning, morning, afternoon and evening. But these two naps must be short and pay attention to high quality, that is, there are four indicators: falling asleep quickly, sleeping deeply for less than an hour, and waking up with a unique spirit.
