The biological clock refers to the biological timetable hidden in the human body. It will tell people when to rest, sleep, do and work. The body's biological clock has a 24-hour cycle, which is related to the unique function of the pineal gland in the brain. When the day darkens, melatonin is secreted to guide people to sleep; At dawn, it will stop secreting again, making people excited and active. There are two kinds of kimonos in the body's biological clock: the day clock and the year clock. The magic of "sun clock" is that at 1: 00, the human body enters a shallow sleep stage, and it is easy to wake up and is particularly sensitive to pain. At 2: 00, most organs of the body are at the slowest time of the day. On the other hand, the liver is trying to detoxify the human body. At this time, people's eyesight is the worst. At 3: 00, the whole body is at rest and the muscles are completely relaxed. At 4: 00, the blood pressure is the lowest and the blood supply to the human brain is the least. Therefore, the elderly are prone to cardiovascular and cerebrovascular accidents at this time. After a certain period of sleep at 5: 00, the human body got a full rest. Get up at this time and look full of energy. At 6: 00, the blood pressure began to rise and the heart rate gradually increased. At 7 o'clock, the body temperature began to rise, and human immunity was the strongest. At 8: 00, the toxic substances in the skin were completely eliminated, and the content of sex hormones was the highest. At 9: 00, the skin pain was relieved. This time is a good time to see a doctor for an injection. 10: 00 energetic, most suitable for work. 1 1: 00 is the most energetic, and the human body is not easy to feel tired. 12: 00 After a morning's work, the human body needs a rest. 13: 00, gastric juice is the most secreted, and the gastrointestinal tract is working hard. People feel a little tired and need a short rest. 14: 00: The stress function of human body decreased, and the whole body was slow to respond. 15: 00, the body temperature was the highest, and the working ability began to recover. 16: 00 blood sugar rises, and the face is the reddest. 17: 00 has the highest working efficiency, the most active lung breathing movement, and the amount of exercise can be doubled. 18: 00, people's pain decreased again. 19: 00 Blood pressure increased slightly. At this time, people's mood is the most unstable. At 20: 00, the memory is the strongest, and the brain reacts abnormally quickly. 2 1: 00, the brain is active and suitable for learning and memory. At 2200 hours, breathing began to slow down and body temperature gradually dropped. At 23: 00, the whole body is at rest, and the fatigue of the day begins to ease. Sleep at 24: 00, and your physical strength is fully restored. The magical characteristics of "mid-year" are: everything recovers in spring, the function of human organs is strengthened, and the human body begins to enter a state of consumption. Summer: the most vigorous season, when the organs are overloaded and the human body reaches the maximum consumption. Autumn: nature is in a state of gradual harvest, and human consumption begins to decline. Winter: natural creatures are in hibernation, and the human body conserves energy to adapt to the next summer. Understand that the biological clock exists in everyone and is the rhythm formed in daily life. From 23 pm to 5 am, the body is in a state of rest and cell repair. Under normal circumstances, at this time, the body and brain quickly eliminate all interference, fall asleep, and cells begin to repair. Until 2 o'clock, except the liver, most tissues and organs basically stopped working. At this time, the liver is nervously removing toxins from the body, and the human body is undergoing a major cleaning. Drinking alcohol is the most harmful to the liver at this time. At three or four o'clock, people are at rest, their physical strength is almost completely lost, their blood pressure, pulse and breathing are in the weakest state, and their blood supply is the least. People are prone to accidents at this time. After 6 o'clock, blood pressure rises, the heart beats faster, and the body begins to wake up. What are the symptoms after the biological clock is reversed? Breaking the regular life for a long time will cause disorder of biological clock. People will feel inattention, poor thinking and judgment, fatigue, listlessness, low work and study efficiency, sleep and eating disorders, "sleepy and unable to sleep, hungry and unable to eat", the body's immunity is seriously reduced, and it is easy to get sick. For example, the primary disease will aggravate the condition. People with a strong pace of life are more obvious and slow to recover. Adjust the biological clock to adjust sleep: people with weak pace of life can adjust themselves quickly. People with obvious symptoms of discomfort can take part in a week's adjustment with the help of drugs, which are used according to personal habits. Soak your feet with hot water one hour before going to bed. The water temperature is enough for your feet. Soak your ankles and rub your feet. If the water is cold and then heated, keep the water temperature, soak for 15 minutes, rub your feet with your hands and then come out, cross your legs and rub your feet again. Measure the distance between the sole of the foot and the heel (the index finger 1-2 joint is one inch), rub it up to Yongquan point with your thumb, and rub your feet repeatedly for 5 minutes. Then do abdominal breathing 10 times, slowly, 4-6 times per minute. Adjust diet: Due to long-term observation of the World Cup, the diet is irregular, the gastrointestinal biological clock is abnormal, and the tired body also produces a lot of acidic substances. At this time, you should eat alkaline foods (milk, vegetables, fresh mushrooms, dried beans and fruits) in moderation. Frying, high-calorie, glutinous rice, irritating and acidic foods (meat, fish, poultry, eggs and cereals) should not be selected. These foods not only increase the burden on the gastrointestinal tract, but also affect the body's acid excretion, aggravate the disorder of gastrointestinal biological clock and prolong discomfort. Avoid drinking strong tea, coffee and spirits for a short time, and it is appropriate to have seven or eight full dinners. To adjust the biological clock, we must first supplement the excessive consumption and loss of micronutrients, especially the vitamin B family. Vitamin B complex, vitamin B 12 and vitamin C can be taken to restore human vitality quickly, and the combined application effect is better. Moderate exercise: physical exercise, mainly static events, such as yoga, Pilates, Sherbin, etc.
