The so-called health preservation refers to a "systematic lifestyle". The arrangement here is a conscious and purposeful activity. Health preservation is the function of comprehensive factors, involving all aspects of daily life. In recent years, countries all over the world are looking for the "best regimen". At present, the "biological clock regimen" is popular in the world. Its basic viewpoint and method are: all kinds of physiological activities of human body have a "predetermined timetable", that is, biological clock.

The biological clock controls all kinds of human activities. If people's activities can meet the requirements of biological clock, they can reach the realm of health, longevity, wisdom, happiness and beauty. If we can't abide by it, with the different degree of violation, the human body will suffer different damages, such as fatigue, mental retardation, unhappiness, premature aging, disease and even death. Therefore, all aspects of our lives should be unified into the procedure of "doing things according to the laws of biological clock".

Scientific research shows that people's life, survival and activities have periodic rhythm laws. These regular activities are controlled, manipulated and regulated by the "biological clock" composed of many "gear" genes and central "escape wheel" genes in the human body. 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.

The former Soviet Union scientist Feronov once did a study. The biological clock of the human body for 24 hours a day is as follows:

Most people have entered the stage of light sleep and easy to wake up, and are particularly sensitive to pain.

Except for the liver, most organs work slowly.

Full body rest, complete muscle relaxation, low blood pressure, less pulse and breathing times.

The blood supply to the brain is the least, and many seriously ill patients die at this time.

People's sleep has gone through several stages, and they will soon be full of energy after getting up.

Blood pressure rises and the heart beats faster.

The human immune function is particularly strong.

The toxic substances in the liver are all exhausted, so don't drink alcohol at this time.

Mental vitality is improved, and the heart is working at full capacity.

Energetic is the best working time.

The heart still works hard, and the human body is not easy to feel tired.

It's the general mobilization stage.

The liver is resting, the best working time is about to pass, and I feel very tired.

It is the second lowest point of the day, and the response is slow.

Human organs are the most sensitive, and their working ability gradually recovers.

The decomposition of sugar in the blood will increase, but it will soon decrease.

The work efficiency is higher, and the amount of training for athletes can be doubled.

I feel less pain and want to increase my activity.

When blood pressure rises, the spirit is the most unstable, and anything will cause a quarrel.

The heaviest weight, abnormal rapid response.

Nerve activity is normal, memory is enhanced, and you can remember what you didn't remember during the day.

Body temperature drops.

The human body is ready to rest and continue to do the work of repairing cells.

At the last point of day and night, if you go to bed at 22 o'clock, it's time to fall asleep. This is an overview of the 24-hour rhythm change law of human body.

In addition, the four seasons change, and the human body is also rhythmic. Traditional Chinese medicine believes that the climate of four seasons corresponds to the qi of zang-fu organs. Su Wen's Theory of Dirty Qi says: "Liver governs spring, foot jueyin and shaoyang are the main indications ... heart governs summer, hand governs shaoyin and sun ... spleen governs summer, foot Taiyin and Yangming are the main indications ... lung governs autumn, hand Taiyin and Yangming are the main indications ... kidney governs winter, foot Shaoyin and sun are the main indications." In other words, each of the five internal organs has its own qi. Within a day, qi runs in the body, and with the change of yin and yang day and night, it goes on and on, pushing the whole body's qi and blood to run endlessly.

Knowing the above laws of human biological clock, we can make good use of it. Since scientists discovered the mystery of the human biological clock, they have studied and discovered how to conform to the internal laws of the human body.

The best time to get up: 5-6 am is the "climax" of the human biological clock. When you get up, you will be full of energy.

Best drinking time: drinking water after getting up can not only replenish the water consumed overnight, but also dilute the blood, which has the functions of gastric lavage and preventing thrombosis. 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. 1 hour, 1 glass of water before meals, which helps to secrete digestive juice and promote appetite. Drinking less water before going to bed can promote blood circulation.

The best time to use your brain: at 8: 00 a.m., your brain is rigorous and thorough in thinking, full of energy at 10 a.m., most responsive at 2: 00 p.m. and most memorable at 8: 00 p.m.

The best working time: from 10 to 3 pm, the work efficiency is improved, generally mental work in the morning and physical work in the afternoon.

The best injection time: generally choose 9 am, which is the least sensitive to pain.

Best lunch break: The activity ability of human brain is the lowest at 1 in the afternoon, so it is most suitable to have a lunch break at 1 in the afternoon.

The best exercise time: avoid before winter and spring 1-2 months, 6-7 am. At 5-6 am in summer and autumn, the air is fresh and the climate is cool, which is a good time to exercise. Doing aerobic exercise from 9: 00 a.m. to 4: 00 p.m. is good for people's health, because at this time the muscle temperature is high, the viscosity is the least, and the joints are the most flexible.

The best time to lose weight: 45 minutes after a meal, walking for 20 minutes at a speed of 5 kilometers per hour, the fastest calorie consumption, is conducive to weight loss.

The best time to brush your teeth: except in the morning, 3 minutes after each meal, because bacteria in the mouth decompose sucrose and starch in food residue, which will corrode and dissolve human tooth glaze.

The best time to eat fruit: 65438+ 0 hours before meals and 2 hours after meals. Eating fruit nutrition is best absorbed by the small intestine.

The best time to drink milk: besides supplementing human nutrition, milk also has hypnotic and sedative effects, so the best time to drink milk is 8-9 pm. At this time, drinking milk can not only supplement nutrition, but also sleep peacefully.

Optimal sleep time: The body's biological clock ebbs at night 10- 1 1, so the optimal sleep time is 9- 10.
