How is the biological clock formed?

The biological clock is a self-protection mechanism of the human body, which is cultivated under our long-term regular routine. Once cultivated, getting up to sleep, eating and excreting, and studying and entertaining will all produce excitement at a certain point in time. Having a good biological clock is of great benefit to our physical and mental health.

The biological clock is also known as the biological clock. It is an invisible "clock" in the organism, which is actually the internal rhythm of the life activities of the organism, which is determined by the time structure sequence in the organism.

The human body has different periodic rhythms with time, such as time, day, week, month, year, etc. For example, a person's biological clock.

The body temperature is not exactly the same in 24 hours, the lowest at 4 a.m. and the highest at 6 p.m., but the difference is within 1. Changes in the body's normal circadian rhythm are often a precursor or danger sign of disease, and correcting the rhythm can prevent and treat certain diseases. The research of many scholars has pointed out that according to the biological rhythm of people's psychological, intellectual and physical activities, to arrange a day, a week, a month, a year of work and rest system, can improve work efficiency and academic performance, reduce fatigue, prevent diseases and prevent accidents, etc.

On the other hand, if you suddenly do not follow the rhythm of the body's biological clock, you will feel physically tired and mentally uncomfortable.

1.The effect of the alternation of day and night on living things.

The cycle of day and night has given animals a circadian clock pattern (e.g., rats) or nocturnal (e.g., humans and many other mammals), and our lives are affected by the cycle of day and night. For plants, the alternation of day and night is the process of energy or sugar production, release, aggregation and utilization (for example, grapes will photosynthesize to produce energy during the day, and respiration to release energy at night; During the day, sugar is consumed to survive. At night, energy is built up for tomorrow), and this effect on plants also indirectly affects humans.

2.The effects of seasonal changes on living things.

1) Effect on plants: such as a hundred flowers blooming in spring, rapid growth of plants in summer, fruitful fruits in autumn, dormant (falling leaves) in winter, etc., "sleeping" until the next spring before germinating and growing.

2) Impact on animals: Some animal life changes regularly with the four seasons, such as hairy-footed bees feeding on nectar in spring, breeding offspring in summer, building nests and storing winter food in autumn, and hiding in nests in winter. Some animals also migrate or hibernate with the seasons, such as geese and hedgehogs.

3) the impact on humans; Farmers plant, care for, and harvest crops according to the seasons, and people change their clothes according to the seasons.

Most plants sprout and grow in the spring when temperatures begin to rise, followed by flower buds: flowering and fruiting in summer and autumn heat; In late autumn, the leaves fall at low temperatures, and then go into dormancy. This stage of growth and development, such as germination, growth, emergence of flower buds, flowering, fruiting, defoliation, and dormancy, is called phenological stage.

The phenological period is a true and accurate reflection of the comprehensive climatic conditions (especially temperature) of each year, and it is used to predict agricultural time, pest emergence period, etc., which is more accurate than the average temperature and season.

Phaseolus vulgaris leaves are horizontal during the day and droop at night, which is called sleep, such as continuous light or continuous darkness of Phaseolus vulgaris, and keep the temperature constant, Phaseolus vulgaris leaves are still flat during the day and droop at night, indicating that the sleeping motor receptors of Phaseolus vulgaris are controlled by an endogenous mechanism, which is the biological clock. An important feature of the biological clock is that it can be transferred, and the main factor in the allocation of the biological clock is light. Therefore, the cycle of the circadian clock is always approximately 24 hours.

The biological clock is also known as the biological clock. It is an invisible "clock" in the organism, which is actually the internal rhythm of the life activities of the organism, which is determined by the time structure sequence in the organism.

Through the study of the biological clock, new disciplines such as chronobiology, chronology and chronology have emerged. The study of the biological clock is of great significance in medicine and plays a role in promoting the basic theoretical research of biology. In 2017, three American scientists were awarded the Nobel Prize in Physiology or Medicine for their research on the molecular mechanisms by which the circadian clock operates.

The biological clock, also known as the biological clock, is the internal rhythm of the life activities of an organism, which is determined by the temporal structure of the organism.

The role of biological species in the human body is to determine people's sleep and wakefulness, and the biological clock regulates various organs in the body to function in a 24-hour cycle according to the instructions of the brain.

All animals on Earth have a physiological mechanism called the "biological clock", which is a 24-hour cyclic rhythm from day to night, such as a light-dark cycle, which coincides with the rotation of the Earth.

The biological clock is influenced by the brain's hypothalamus"Suprachiasmatic nucleus"The controlled, like all mammals, is the area of the human brain where the SCN is located above the palate of the mouth, and the circadian rhythm of sleep, wakefulness, and eating behaviors are attributed to the biological clock.
