When is the fatigue period of people?

At the beginning of the 20th century, German doctor Ferris and Austrian psychologist Swat Bo discovered a strange phenomenon at the same time: some patients need treatment every 23 or 28 days because of headache, mental fatigue and other reasons. So they called 23 days "the law of physical strength" and 28 days "the law of emotion". Twenty years later, Trichet found that students' intelligence changes in 33 days, so he called it "the law of intelligence". Later, people called it "physical law", "intellectual law" and "emotional law". At 1937. The first biological rhythm conference was held internationally. 1960, an international conference devoted to biological rhythm was held in the United States, and biological rhythm was formally introduced as a new discipline. 198 1 year, Science Illustrated published the article "Uncovering the Secret of Biological Rhythm" (198 1 February), which introduced the wonderful biological rhythm to domestic readers and aroused great interest. Since then, many places and departments in China have also carried out the application research of biological rhythm, and the relevant state departments have also issued documents affirming the role of biological rhythm in promoting safe production.

In a person's life, the three biological rhythms generally remain unchanged and are not affected by any acquired influence. All three rhythms have their own high tide, low tide and key days. The periodic changes of people's physical strength, emotion and intelligence can all be expressed by curves. These three curves all start from the date of birth, start from the midline, first enter the high tide period, then go through the critical period, then turn into the low tide period, and so on. The day when the curve is above the center line is the high tide period, whereas the day below the center line is the low tide period (the days of high tide period and low tide period are equal), and the day crossing the center line (strictly speaking, including its front and back 1 day) is the key period. At the climax of physical strength, people are full of energy and physical strength, and at the low tide, people are tired and listless; In the period of emotional climax, people are in a good mood and high spirits, and all activities are shrouded in happy emotions. During the low tide, the mood is irritable, depressed and unresponsive, and all activities are shrouded in repressed emotions; At the intellectual climax, people's thinking is sharp and their memory is strong, while at the low tide, people's thinking is slow and forgetful, and their understanding is poor. In the critical period of biological rhythm, the body is in an unstable transition state, feeling particularly bad about itself, declining health level, emotional irritability, and easy to get angry inexplicably. At this time, people's related abilities and physical coordination are poor, and they are prone to make mistakes, get sick and have accidents in activities. The periods of the three rhythms are different, but sometimes they coincide in one day, that is, the double critical day or the triple critical day. The coincidence of key days intensifies the possibility of accidents, so people in the world call double key days and three key days "dangerous days" for one person.

According to the statistical analysis of 1 0,000 car accidents by Swedish scholar Schwein, the accidents occurred in the critical period of the biological rhythm of the perpetrators, which was not critical 1 1 times. The statistical analysis of 497 accidents by the former German Federal Ministry of Agricultural Machinery found that 97.8% of the accidents occurred in the critical period of the biological rhythm of the perpetrators. China Hangang General Plant analyzed and counted 1973 ~ 1986 174 accidents, and the results showed that 66% of the accidents occurred in the critical period of biological rhythm. The analysis and statistics of 105 industrial accidents by the safety technology department of Shanghai Ferroalloy Factory show that 63.8% of the accident parties are in the critical period and low tide period of their biological rhythm.

As we all know, man is the most active factor in productivity. To realize safe production, we should not only pay attention to equipment, but also pay attention to improving the political and professional quality of workers, ignoring their physical and mental state. Safety in production is about science, and the understanding of science is not limited to scientific rules and regulations and scientific management methods, but also includes scientific understanding of workers and scientific arrangement of work tasks and working hours. If every worker knows his three biological rhythms and arranges production scientifically, the total number of accidents will be minimized.

Safety is the eternal theme of coal mine production. Although various coal mines have taken many measures to take strict precautions, accidents may occur at any time. Statistics show that ignoring the biological three rhythms is an important reason for the high total number of coal mine accidents. Therefore, in order to promote the sustainable, stable and healthy development of coal mine system safety, strengthen the management and behavior control of people in the process of safety production, consolidate the foundation of safety management, realize scientific management, innovate means and nip in the bud, it is of great significance to apply the human biological rhythm fingerprint identification safety management system to coal mine safety production.

Jinan Zhengping Automation Equipment Co., Ltd. organically combines human fingerprint identification, human biological rhythm and safety management to develop a safety management system for human biological rhythm fingerprint identification. Human biological rhythm fingerprint identification safety management system is a kind of safety management method based on the comprehensive analysis of employee's birth date and fingerprint identification, and obtains the change results of physical strength, intelligence and emotion in different periods, and analyzes these factors affecting safety production, so as to formulate preventive measures and implement them.

Criticality of Human Biological Rhythm and Corresponding Security Measures

A. Critical state of the body: When a person is in a critical period of physical strength, his body is in a slightly weaker period than usual, that is, a period of relative fatigue, and rest should be adjusted in time.

B. Key intelligence: When there is a critical intelligence period, the intelligence is slower than usual, so we should always pay attention to the precautions in the production process to prevent accidents.

C. Emotional criticality: In the critical period of emotion, the mood is in a period of fluctuation, so it is necessary to adjust the mood and mentality in time to avoid bad behaviors that affect safety in production.

D. Double criticality of physical strength and intelligence: When there is a double criticality of physical strength and intelligence, physical weakness and mental retardation will occur, so it is necessary to adjust rest in time and arrange work properly.

E. Dual criticality of physical strength and emotion: When physical strength and emotion are dual criticality, physical weakness and emotional abnormality are easy to occur. Attention should be paid to rest and control emotions, arrange off-duty, and do a good job in helping and promoting education.

F. Double criticality of emotion and intelligence: When double criticality of emotion and intelligence, emotional fluctuation and mental retardation are easy to occur. You should adjust your mood and mentality, do a good job in helping and propaganda, and don't go down the well.

G. Three thresholds of physical strength, intelligence and emotion: When three thresholds of physical strength, intelligence and emotion occur, physical discomfort, mental retardation and abnormal mood fluctuation are easy to occur. Do a good job in helping and promoting education, focusing on management, not underground. District teams should adjust their off-duty hours.

Practice has proved that the implementation of human biological rhythm control can effectively control people's unsafe behavior in advance and avoid some adverse consequences. In the process of applying the human biological rhythm fingerprint identification safety management system, paying attention to comprehensive analysis, reminding in time, eliminating carelessness and perseverance can completely become a good auxiliary means in coal mine safety production management and play a positive role, thus making safety production management more important.

The life activities and habits of every living thing have certain periodic changes. The internal rhythm of organisms often corresponds to the periodic changes of the environment, and almost all of them occur in a fixed period of time, showing the same periodic life rhythm and regulating the behavior and physiological changes of organisms. For example, migratory birds migrate in the spring and autumn, animals in the North and South poles change their hair with the seasons, butterflies mostly move during the day, moths mostly move at night, roosters crow in the morning, owls rest in the bushes during the day, bats fly out to catch insects at dusk, morning glory blooms, cordate telosma smells in the evening, and noon flowers bloom in the scorching sun. Biological rhythm is a clock-like mechanism formed by the body in the long evolution process. It can adjust its physiological activities with the change of time, so that it can start, proceed and end in a certain period of time. The cause of biological rhythm is a complex physiological process and the result of chemical and physical changes in organisms. According to analysis, there may be many factors to help the body adjust time, such as temperature, light, chemical activity of enzymes, regulation of nervous system, hormones and so on. According to the same biological dose, patients take it at different times, and the curative effect is different. Chronobiology has been paid more and more attention in medical treatment. According to the internal rhythm of human body, the best work and rest system can improve work efficiency and prevent diseases and accidents.
