Follow the laws of nature, conform to the body's own biological clock, and do it right at the five best times every day?

There is an invisible "clock" in living things, and people's life activities are carried out according to the running law of this "clock".

For example, many physiological indexes of people, such as respiration, blood pressure, body temperature and hormone secretion, are changing rhythmically according to the laws of seasons and day and night, which is the phenomenon of "biological clock" in the human body.

The biological clock controls all physiological functions of the human body, making all life activities of the human body change periodically according to certain laws.

The biological clock is actually the inherent rhythm of an organism's life activities, which is determined by the time structure order inside the organism.

Scientific research shows that human rhythmic life activities are controlled, manipulated and regulated by a "biological clock" composed of many "gear" genes and central "escape wheel" genes.

The position of the human biological clock is in the suprachiasmatic nucleus of the brain, which dominates the change law of the biological clock of the whole human body and different tissues and organs.

To ensure good health, it is necessary to establish a scientific and reasonable work and rest system in work and rest habits. This is because a regular work and rest system can form a benign stimulus in the human central nervous system, establish various rhythmic conditioned reflex, and make the physiological activities of various tissues and organs go on tirelessly for a long time.

Make people better adapt to the external environment and improve human health. This is also an important way to keep fit and prolong life. Therefore, all aspects of our lives should be unified into the procedure of "doing things according to the laws of biological clock".

Optimal rest time

At 6 ~ 7 in the morning, when I just woke up in the morning, after a night's rest, my brain eliminated the fatigue of the previous day and became active. It is more appropriate to learn something that is difficult to remember but must be remembered at this moment. This is the first efficient period of a day's study.

Optimal sleep time

It's 9 ~ 10 at night. If you don't fall asleep after 1 1 at night, it will be more difficult to fall asleep after 12. People's brain has the lowest activity ability at around L'clock in the afternoon, and a nap is the most suitable at this time.

Optimal brain time

(1) At 8 o'clock in the morning, the brain has already

Strict and thorough thinking ability.

(2) Energetic at 10 am:

The most agile reaction is at 2 pm. Therefore, 10 am works most efficiently until 3 pm.

Generally speaking, the morning is suitable for mental work and the afternoon is suitable for manual work. In addition, memory is strongest at 8 pm.

Optimum exercise time

Morning exercise, the first exercise in winter and spring 1 and two months should avoid 6-7 am and 5-6 am in summer and autumn. The fresh air and cool climate are good opportunities for physical exercise.

Doing aerobics after 9: 00 am and 4: 00 pm is good for your health, because at this time, the muscle temperature is high, the viscosity is the lowest, and the joints are the most flexible.

Optimum drinking time

The human body has the highest probability of myocardial infarction at 9: 00 am. Therefore, drinking water after getting up can supplement the water consumption for one night, dilute the blood, reduce the blood viscosity, prevent myocardial infarction and flush the gastrointestinal tract:

Drinking water in the morning 10 and around 3 pm can replenish the water lost by sweating and urination at work and prevent acidification of the human body;

Drinking 1 hour/glass of water before meals can help the secretion of digestive juice and promote appetite. Drinking water before going to bed can dilute blood, make circulation smooth and reduce the chance of cerebral vascular embolism, which shows that drinking water at different times has different significance in preventing different diseases.

The human body is a creation of nature, and it is a unified whole with nature. Of course, it needs to conform to the laws of nature. If a person works irregularly for a long time, it will change the amount of hormone secretion in the body, lead to nervous disorder and affect the biological clock in the body.

Therefore, when people do something, they should adapt to the changes of their bodies, make timely adjustments and keep healthy, which is also the truth that natural selection tells us.
