What is a biological clock?

The biological clock of human body: The process of human life is complex and wonderful, and a charming "symphony of biological rhythm" is played all the time. This is what people usually call the biological clock. Biological clock, also known as biological rhythm, refers to the phenomenon that organisms change periodically at any time, including physiology, behavior and morphological structure. Scientists have found that biological clocks are various. As far as the human body is concerned, more than one hundred species have been found. The biological clock has a great influence on people's health. The rest and rest of the whole human being in a day and night cycle, the physiological indexes of the human body, such as body temperature, blood pressure and pulse; Physical strength, emotion, intelligence and women's menstrual cycle; Signals in the human body, such as brain waves, ECG waves, meridian potentials, changes in human electromagnetic fields, etc., will change periodically with the change of day and night. No one denies that this series of phenomena has nothing to do with human health. Science has found that when the biological clock is disordered, human beings and even all life are prone to illness, aging or death. Some people's biological clocks have been relatively stable for decades and they are in good health. Once the biological clock is broken and in a state of disorder for a long time, it will produce various discomforts or diseases, and some even endanger life. It is said that the trademark of European famous jujube whisky is the head of a long-lived old man who lived 152 years old. At that time, the king of England wanted to see the long-lived old man, so he invited him to the palace to eat, drink and have fun to show his hospitality. Who knows, because the law of life was suddenly changed, the old man died a week later. In our life, there are also some old people's health. They have worked all day for decades and become healthier and healthier. One day, due to their filial piety, they were given a rest time to "enjoy the rest". As a result, they either felt uncomfortable or could not afford to get sick. Some newly retired old people are not as healthy as when they go to work, which is related to the sudden change of biological clock. We believe that young people should understand, discover and master their biological clocks as soon as possible, and then gradually adapt to them so that they can play a positive role. The elderly should maintain the biological clock formed in decades, and don't change it easily, so as not to cause biological clock disorder and affect physical and mental health. Filial sons and daughters, don't let the old people indulge your "filial piety" easily. According to a survey, in a health care and rehabilitation center for the elderly, several 90-year-old people were in normal physical condition and mental state at home, and their children sent them to the center to get good medical security. However, in less than half a month, all these old people died "disease-free". Whether this has anything to do with the old man's biological clock being changed, we can't get into it. However, we believe that understanding, mastering and adapting to the biological clock will help to maintain and improve people's physical and mental health.
