In recent years, chronobiology holds that the life of organisms and plants changes with the periodic movement of day and night and four seasons, revealing the periodic rhythm of physiological activities. In ancient medicine, heaven and earth were regarded as a big universe, and human body was regarded as a small universe, which meant that the big and small universes were closely connected. Most activities of healthy people show a circadian rhythm, which is suitable for the 24-hour cycle formed by the regular rotation of the earth, indicating that the circadian rhythm is synchronized by the periodic changes of the external environment (light intensity and temperature). Body temperature, pulse, blood pressure, oxygen consumption and hormone secretion level all have circadian rhythm changes. The structure of biological approximate clock is called "biological clock". The periodic rhythm is called the "day clock" of 24 4 hours, the "month clock" of 29.53 5 days and the "year clock" of 12 February. Chronobiology reminds us that the life activities of plants, animals and even people have a biological clock that is "lasting", "self-winding" and "self-adjusting". This is the biological clock of the human body, and a normal biological clock means that the human body is healthy.
The biological clock, like a clock, works day and night, and its working rhythm will not be affected by the surrounding environment. Therefore, the periodic oscillation rhythm of the biological clock is endogenous or independently carried out in different organs. The existence of biological clock is of great biological significance. It can make organisms adapt to periodic environmental changes, especially migration, foraging, mating and procreation, which are essential for survival and reproduction, and even make arrangements in advance. For example, glucocorticoids have risen before getting up in the morning, so be prepared for daytime activities in advance. The biological adaptability is limited, and the physiological cycle can only follow the external periodicity within a certain range. When the deviation is too large and the external environment changes, the stimulus is too strong and too weak, which makes the physiological oscillation deviant, interferes with the normal operation of the biological clock, causes the disorder of the rhythm position of different organs of the individual, destroys the orderly cooperation, and will lead to various diseases. Therefore, the biological clock needs our careful care and protection. As long as the biological clock is normal, human health can be guaranteed. Therefore, in life, protecting the biological clock is the core of self-care.
The most effective way to protect the biological clock is to ensure your regular life. We should work and rest on time, eat a balanced diet and exercise actively to form a "system", that is, we should adhere to it all year round, and holidays are no exception. In the process of human life, many physiological phenomena are controlled by a substance related to time factors. Since the birth of living things, the change of illumination caused by the rise and fall of the sun has established a synchronous relationship with the life activities in living things. After a long period of evolution, organisms have formed the rules of activities in the body according to the laws of the sun, which are controlled by biological clocks. The human biological clock is a complex physiological process, which is "commanded" by the pineal gland. The pineal gland is a pea-sized gland in the brain, and the hormone secreted is called pineal gland (also called melatonin). In short, only by ensuring the law of life can we ensure the health of the biological clock. Only when the biological clock is healthy can the human body be healthy.
All activities of human body are regular. Studies have found that a person's body temperature is the lowest at 2-6 am and the highest at 5-6 pm. The growth of cancer cells is also regular. When the growth rate is the fastest, radiotherapy is the easiest way to kill cancer cells. In addition, there are blood sugar content, basal metabolic rate, meridian potential and so on. It also changes with the change of day and night and runs with the biological clock. The disorder of biological clock, the extreme decrease of melatonin and the loss of normal rhythm will affect the disorder of many physiological functions in the body, resulting in sleep disorders, endocrine disorders, decreased immune function, damage to health and even diseases. Therefore, in daily life and work, we should follow the law of day and night and the law of seasons, and try to avoid or reduce the interference with the biological clock. Have a regular daily life, a normal work and rest, a reasonable diet, do not interfere with the normal operation of living things, and maintain natural health.
Friends who pay more attention to health care should have heard of the "biological clock health care method", which is to keep health through the biological clock. According to this regimen, various physiological activities of the human body have regular schedules, which are controlled by the biological clock. If people's activities can meet the requirements of biological clock, they can reach the realm of health, longevity, wisdom, happiness and beauty. Otherwise, the human body will suffer some damage, manifested as fatigue, mental retardation, unhappiness, premature aging and disease. So we do things according to the law of biological clock, so as to achieve the purpose of health preservation. For example: work and rest on time, combining work and rest; Eat on time, don't overeat; Adapt to the four seasons and conform to nature; Get rid of bad habits without harming human function. Only by ensuring a normal biological clock can we get a healthy body.
If you violate the biological clock, there will be a series of discomfort. If you feel uncomfortable, you must make up and correct it in time to avoid further development and cause diseases. Eyeball congestion, staying up too much, can be adjusted by sleep; Black eyes and excessive fatigue can be adjusted by rest; White tongue coating and stomach discomfort can be adjusted by diet; Mental stress and psychological imbalance can be solved by relieving psychological stress, and so on. Only by taking care of yourself, paying attention to yourself, self-care and self-treatment can you have a healthy body.
