1. Health preservation is to maintain life. Guided by the theory of traditional Chinese medicine, we should follow the changing law of the biochemical set of Yin-Yang and Five Elements to scientifically recuperate human health and vitality. Psychological health preservation refers to the method of nourishing the heart, regulating the mood and life, so as to achieve the purpose of maintaining the body, reducing diseases, improving health and prolonging life. 2. The basic principles of health care adapt to the laws of nature. People's life activities follow the objective laws of nature. The human body itself has the ability to basically adapt to the laws of natural changes. If people can master its laws and take various health care measures to adapt to its changes, they can avoid misfortune, prevent diseases and delay aging. For example, "the sun in spring and summer, the yin in autumn and winter, from its roots." The principle of "keeping healthy according to the time" is to keep healthy according to the rhythm of the ups and downs of Yin and Yang in four seasons, so as to synchronize the physiological activities of the human body with the cycle of natural changes and maintain the coordination and unity of the internal and external environment of the body. Pay attention to mental conditioning 1 avoid bad stimulation mainly includes two aspects: First, try to avoid the influence of bad stimulation from the external environment on the human body. Second, actively treat physical diseases and prevent their adverse stimulation by endogenous factors. Physical illness will not only cause pain and other adverse stimuli to patients, but also cause mental burden to patients when they are seriously ill or sick for a long time. Their endogenous stimulation will also produce abnormal emotional changes, aggravate the condition, affect rehabilitation and lead to premature aging. 2. Improve self-psychological adjustment ability. Excessive emotional stimulation can only become a pathogenic factor if it is beyond the scope of human psychological adjustment. People are required to be good at self-psychological adjustment through health-keeping activities, transfer emotional reactions through experience and ideological activities, eliminate their own bad stimuli, and maintain a good attitude. Proper sexual intercourse is not only beneficial to personal health, but also of great significance to the prosperity of the nation, the stability and harmony of society and family. Therefore, all previous generations of physicians did not pay attention to sexual life. 4. Pay attention to physical exercise. Physical exercise can not only promote the smooth flow of qi and blood, make the body strong, muscular and enhance physical fitness, but also regulate people's mental and emotional activities through "movement" and "quietness" and promote people's physical and mental health. Therefore, exercise is an important part of health activities. For physical exercise, it is generally required to exercise moderately and be "tired and tireless". Moreover, it requires gradual progress and perseverance in order to receive the effect of dynamic health preservation. I sincerely agree with the five flavors that "food can dispel evil, consolidate viscera, replenish qi and blood, make people happy and feel refreshed". Therefore, predecessors attached great importance to diet and health preservation. Food and nutrition also need to follow certain principles: 1, arguing about the appropriateness of diet is one of the principles of food and nutrition. Generally speaking, people with hot constitution should eat cold and avoid warm; Those with cold constitution should eat warm food and avoid cold; A healthy person should have a balanced diet and avoid prejudice. 2. A balanced diet requires that the distribution of food and nutrition should be as comprehensive, reasonable and complementary as possible, that is, the principle of balanced diet. For example, on Su Wen's method of storing qi, it is described that "poison attacks evil, grains nourish, five fruits help, five livestock benefit, five vegetables supplement, and the smell is combined to replenish essence." It has already included the understanding that dietary distribution in food and nutrition needs comprehensive and reasonable nutrition. It is an important principle in health preservation to prevent the invasion of diseases and pathogens and carefully avoid external pathogens. Mainly reflected in three aspects: First, "fake evil thieves, avoid it sometimes." The second is to pay attention to "avoiding its poisonous gas" to prevent illness and easy infection. The third is to implement drug prevention. 3. Health-Dietary Nutrition Combination+Skillful Choice of Fat+Quantification of Three Meals+Beneficial Cold Food+Chewing Slowly+Eating More and Moving More+Eating Less and Eating More+Intake Enough Micronutrients = Health+Bodybuilding Nutrition Combination: After a long-term study, the famous Egyptian scholar Nufuer pointed out that protein, carbohydrates and fat are equally important to health and are indispensable. The key lies in clever collocation, that is, matching greasy food with beans and vegetables as much as possible. This will not only increase the nutritional intake, but also help to lose weight. Clever choice of fat: it is impossible to eat fat at all, and it is harmful to health. The method of promoting advantages and eliminating disadvantages is a smart choice. According to the analysis of nutritionists, fat can be divided into three categories: the first category can greatly increase the content of human fat and cholesterol, such as the fat in various livestock meat and its products, cream and cheese; The second category has little effect on human cholesterol content, such as chicken, eggs and crustacean fat; The third category is fats that can lower cholesterol, such as olive oil, corn oil and soybean oil. Quantification of three meals: mastering the intake of three meals reasonably is another key to keeping fit. Can't lead to differences in daily food intake because of personal preferences. According to estimates, the daily food intake of young men and women is roughly as follows: grain 500g, eggs 1, lean meat 100g, fish 150g, beans 200g, vegetables 500g, milk 200g and vegetable oil 25g. Eating cold food is beneficial: hot food can increase human heat energy, and eating cold food must be heated before it can enter the digestive process, so it can consume some calories. In other words, eating cold food consumes energy, especially those who are fat, and should eat more cold food in hot summer. But it should be noted that cold food should not be too cold, and too cold food will stimulate the gastrointestinal tract. Chew slowly: Chewing can consume a certain amount of calories, and eating the same food is more conducive to maintaining a moderate weight than gorging. According to butyl Nakamura's observation in the Department of Nutrition, Hamami University, obese men eat for 8 to 10 minutes, while thin people need to chew for 13 to 16 minutes. For the same food, obese people only chew 7.7 to 8. 1 time, while thin people chew 8.9 to 9.4 times. After limiting the eating speed of obese people 19 weeks, men can lose 4000 grams and women can lose 4500 grams. Eat more and exercise more: Although overeating is not conducive to weight stability, it is hard for many people to avoid it. What should I do? It is reasonable to sacrifice the next meal to offset the excessive calories taken in the last meal. In order not to affect health, it is better to sacrifice dinner. One is that being hungry for a while is harmless to the human body, and the other is that the calories consumed after falling asleep at night are very limited. The most fundamental way is to exercise more. Studies show that fat people and thin people consume about the same amount of calories at night. The key point is that during the day, fat people have less activities, and their internal activities tend to be slow, so that heat energy accumulation is converted into fat. Eat less and eat more: divide the same amount of food into more than five times. Compared with three meals a day, there is no loss of nutrient intake, but the body produces a lot less calories. Relevant survey data show that among people who eat less than three times a day, 57.2% are obese, and 5 1.3% have elevated cholesterol. The incidence of obesity was 28.8% for those who ate more than five times, and only 17.9% for those with high cholesterol. The reason is that the reduction of food intake per meal can reduce the level of insulin in the blood, thus increasing the burning of fatty acids. Adequate micronutrients: In recent years, scientists have found that obesity is related to the deficiency of certain micronutrients, such as vitamin B 1, B6 and nicotinic acid, which are "catalysts" for fat decomposition. Mineral elements such as calcium, iron and zinc are also necessary substances for energy conversion in the body. These micronutrients are mainly distributed in coarse grains, wild vegetables, green vegetables and dried fruits, so three meals should be diversified, adhere to the principle of matching meat and vegetables and alternating thickness, and you can also eat some fruits and vegetables rich in trace elements outside meals. 4. How to maintain health in winter? Everything is hidden in the soil in winter, and kidney qi should be hidden in the Lord. Health care should be based on nourishing the kidney, otherwise it will hurt the kidney and lead to flaccidity in spring. Fewer students (reducing the ability to adapt to spring). Therefore, Huangdi Neijing said: everything is closed in winter and March, and water and ice are frozen, which does not disturb the yang. Keep your spirit inside, keep warm from the cold and sweat less. Stay in the sun (get more sunshine).
