According to the theory of biological clock, it is proved that morning exercise is not as good as evening exercise. In the morning, most of the body's biological clock is in the stage of rising and accelerating. Exercise urges the biological clock to accelerate again, forming an "accelerated" situation, thus making the biological clock run too fast and "wrong". For example, if a heart attack occurs in the morning, it will be dangerous if it is "accelerated". This is the disadvantage of morning exercise. At night, because the biological clock is slowing down, exercise can make it rise faster and reach the "best state", so the exercise effect is good. For example, athletes are prone to make achievements at this time. However, this does not mean that people must not do morning exercises, because light morning exercises will also avoid the "disadvantages" of the biological clock. \x0d\\x0d\※ Moderate morning exercise can make people full of energy and vitality all day, keep energetic and quick thinking for 24 hours, enhance sense of humor and artistic appeal, avoid endocrine disorders, reduce anxiety and insomnia, and improve sleep quality. That is to say, all this is achieved on the basis that light morning exercise can enhance the order of human biological clock. Of course, these are not immediate and short-term, but should be persistent, that is, "moderate morning exercise" and slight sweating can be effective. 2. "Psychological bath" in bed \ x0d \ x0d "morning exercise" should start as soon as you wake up, and you should "stay in bed for five minutes" instead of getting up immediately, so that the biological clock can adapt from slow to fast. At this time, you can rub your stomach, knock on your teeth, lift your anus, "comb your hair" (using five fingers as a comb is actually a head massage), and have a "psychological bath"-that is, think about happy and comforting things, greet the new day with happiness, and "get up in happiness". At the same time, we should pay attention to whether there is "physiological abnormality in the morning". For example, dizziness in the morning (there is the possibility of cervical hyperosteogeny and increased blood viscosity); Lying in the morning, "hungry" (the possibility of diabetes); Edema in the morning (possible kidney disease and heart disease); Morning stiffness, that is, the whole body joints and muscles are stiff, and the activities are limited (there is the possibility of rheumatoid disease, rheumatism and hyperosteogeny). \x0d\\x0d\3。 Drink water \ x0d \ x0d \ Drink a cup of boiled water (cold or warm) after getting up in the morning to dilute the blood viscosity thickened by overnight evaporation, eliminate toxins accumulated in the body, play the role of "internal washing" and prevent the formation of small thrombus. Then defecate to minimize the reabsorption of intestinal endotoxin by the large intestine. Mechnikov's theory that "large intestine poisoning leads to aging" confirms that toxic substances in the intestine (methane, ammonia, indanthrene, fecal odor, etc. ) is reabsorbed into the blood through the intestinal wall and brought to the cells of the whole body, causing chronic poisoning and leading to aging. Therefore, it should be discharged as soon as possible to reduce reabsorption. \x0d\\x0d\4。 Half-full state \ x0d \ x0d \ Don't do morning exercises on an empty stomach or full stomach, but eat some food, such as bread, milk, eggs, fruits, etc., until you are half full. \x0d\\x0d\5。 Go out after sunrise \ x0d \ x0d \ Before sunrise, the ground air pollution is the heaviest (low temperature at night makes the polluted air settle), and there is less oxygen at this time. After sunrise, the green plants start photosynthesis, inhaling carbon dioxide, spitting out oxygen, and the air is fresh. \x0d\\x0d\6。 Choose a venue \ x0d \ x0d \ Choose a good morning exercise venue, which is safe and pollution-free. \ x0d \ x0d \ ※ In severe cases, it will cause dyspnea, chest tightness, palpitation, etc. Heart disease and cerebrovascular disease should not be specially exercised. \x0d\\x0d\2。 The wind will take away a lot of heat from the human body. Don't think that the temperature in the weather forecast is the temperature in the wind. For example, when it is predicted as the leaf "C", the human body will experience the severe cold of 18 ",instead of the slight cold of the leaf" C "under the 5-level wind. This is the reason why some people who have this misunderstanding get sick after morning exercise in the strong wind, or the old diseases recur or worsen. Old people should pay special attention to keep out the cold in winter morning. \x0d\\x0d\3。 It is not suitable for morning exercise when the temperature is low \ x0d \ x0d \ In winter, the temperature is too low or the temperature drops suddenly, so it is not suitable for morning exercise, especially for the elderly and infirm, who have poor body temperature regulation ability and are prone to catch a cold. \x0d\\x0d\4。 Don't practice in the forest on rainy days, but don't practice in the forest on rainy days. At this time, trees still breathe oxygen and spit carbon without sunlight, which will make people suffer from carbon dioxide poisoning. \x0d\\x0d\5。 Morning exercise is not as early as possible. \x0d\\x0d\ Do you mistakenly think that the earlier you do morning exercises, the better? Some people even get up at 3 or 4 o'clock to exercise and then go back to sleep. This is not only pollution, but also causes the biological clock to be wrongly worn, leading to fatigue, illness, premature aging and premature death. \x0d\\x0d\6。 It is not suitable for exercising on the road \ x0d \ x0d \ along the road, near the factory and in crowded places, which has serious pollution and is harmful to the health.
