How many years have these misunderstandings lied to us？

　　Dog days are the hottest and most yang-filled stage in a year, and it is also an important time for health preservation. Various health preservation methods circulating on the Internet, such as drinking hot water in the dog days to force out the cold in the body, eating more mutton and ginger to "heat up" and so on, have also made many people follow suit for many years. So, are these health care methods reliable? Recently, shenyang evening news and Shenbao all-media reporters interviewed a number of health experts on related issues. They said that the principle of TCM health care is to conform to nature and pay attention to people, time and local conditions. Many widely spread health care methods are not necessarily scientific and not necessarily suitable for everyone. People should not fall into misunderstanding and blindly follow.

　　Myth 1: You can’t eat cold drinks and insist on drinking hot water in the dog days.

　　Some people think that drinking hot water in the dog days can force out the cold that has penetrated into the bone marrow for many years, and you can’t touch a cold drink, otherwise it will damage the yang, destroy human immunity and increase the probability of illness. Is this really the case?

　　Expert analysis: Yuan Renjie, director of the Center for Prevention and Treatment of Diseases of the Fourth People’s Hospital of Shenyang, said that cold and heat are a pair of natural attributes, and they also represent yin and yang, such as "cold and heat are signs of yin and yang" in Huangdi Neijing. A healthy body is "yin and yang are secret, and the spirit is the rule." The most controversial thing about health care in the dog days is that the yang is strong in the dog days, and drinking ice drinks, with the attribute of yin, will hurt the yang, causing the imbalance between yin and yang to be a disease, but this statement is too absolute. Some people do have diarrhea and other symptoms when drinking ice drinks. This is because of the different constitutions. People with yang deficiency are inherently yang-deficient, and drinking yin-cold products makes the deficiency of yang more deficient, so they can’t drink it. So for people with peaceful constitutions, it is not bad to drink a small amount of ice drinks to relieve summer heat. In that case, drinking hot water can force out the cold in the body, in fact, this effect is very small. Hot water can ensure the normal operation of yang on people’s body surface, but the cold in the body is accumulated over time, and there are many reasons for its formation. Drinking hot water alone cannot solve the fundamental problem.

　　Myth 2: Eat more mutton and ginger in "heating with heat"

　　A health post was circulated in a circle of friends: "A bowl of mutton soup in dog days does not require a doctor to prescribe a prescription", saying that eating mutton and drinking mutton soup in dog days can "heat up, sweat and detoxify". In addition, the same is true of "eating radish in winter and ginger in summer, without a doctor prescribing". So, is it really better to eat these hot foods in the dog days?

　　Expert analysis: this statement is not completely correct. If you understand it incorrectly, you will not achieve the purpose of health preservation, but it will be counterproductive. Ginger and mutton are spicy and hot foods, so people with yin deficiency constitution, damp heat constitution constitution and partial qi stagnation constitution should not eat more. However, for some special people, this way of keeping in good health is very suitable. For example, people who eat too much cold and cold food to relieve summer heat are prone to damage the spleen and stomach and consume yang. Proper eating of some foods that are pungent and cold can eliminate these side effects, which is the meaning of "heating with heat". If you don’t have the habit of eating cold food, or have been eating warm food, or are hot people, the "heating with heat" regimen will only "add fuel to the fire" and cause people to get angry.

　　Myth # 3: Practice in summer, exercise after three days of rain, and keep cool.

　　Many people think that summer is very cool after rain and suitable for exercise, so they will take a walk after rain, or go out for running and fitness, breathe the air after rain and feel comfortable. In fact, going to exercise after the rain in summer will aggravate the moisture in the body.

　　Expert analysis: "Practicing 39 in winter and three volts in summer" is the experience summarized by predecessors in the long-term exercise process, which makes sense. However, for the elderly, "training for three days in summer" is not suitable. The climate in dog days is characterized by high temperature, low air pressure and high humidity. In this weather, summer is the main way to maintain health, and quietness is to nourish the heart, with more quietness and less movement. Middle-aged and elderly people must not exercise excessively in midsummer, because sweating will lead to blood viscosity, blood volume reduction and other cardiovascular and cerebrovascular diseases. Exercise in the dog days must avoid high temperature and be carried out in a cool place and at a cool time. It is advisable to do gymnastics, walking, Tai Chi and other light exercises, as long as you sweat slightly. It is very fresh to exercise the air after rain, but the relative humidity is relatively high, and dampness is also easy to invade the human body, especially when sweating after exercise and the hair is wide open, it is necessary to prevent dampness from invading.

　　Myth 4: Prevent heatstroke and catch a cold, and always drink Huoxiang Zhengqi water.

　　Many people carry Huoxiang Zhengqi water with them to prevent heatstroke in summer. However, Huoxiang Zhengqi Water is not suitable for everyone. If the physique is not suitable, taking it blindly will only hurt the body.

　　Expert analysis: The main component of Huoxiang Zhengqi Water is Huoxiang, with Atractylodes lancea, Pericarpium Citri Tangerinae, Magnolia Officinalis, Radix Angelicae Dahuricae, Poria, Pericarpium Arecae, Pinellia ternata, etc., which has the functions of relieving exterior dampness, regulating qi and harmonizing middle energizer. It can be used for treating common cold caused by exogenous wind-cold, internal injury and dampness stagnation or summer injury and summer dampness, with symptoms such as headache, heaviness in chest and diaphragm, abdominal distension and pain, vomiting and diarrhea, etc. When taking it, it needs to be accurate in syndrome differentiation, and it is best to take it under the guidance of pharmacists and doctors. Because the medicine is Xinwenfa powder, it is suitable for patients whose dampness is heavier than heat or cold-dampness. If people with heat-toxic reaction eat Huoxiang Zhengqi, it is equivalent to eating backwards, and the medicine will not only be ineffective but also delay the illness.

　　In addition, Zhao Liren, a health expert at Ministry of Human Resources and Social Security Education and Training Center in China, reminded that Huoxiang Zhengqi Water contains a certain amount of ethanol. If you drink a drink containing ethanol after applying cephalosporins, it will lead to "ethanol accumulation" in the body and a disulfiram-like reaction (also known as sulfur-like reaction of abstinence, which is manifested by symptoms such as facial flushing, headache, abdominal pain, sweating, palpitation and dyspnea). Therefore, be careful not to use cephalosporins when taking Huoxiang Zhengqi Water.

　　Expert advice: mung bean soup after "transformation" has better health care effect.

　　In hot weather, the cool mung bean soup must be the favorite of many people. Then, do you know why mung bean soup can relieve summer heat? How to decoct and match, and the effect of relieving summer heat is better? Let’s listen to the introduction of health expert Zhao Liren.

　　Drinking mung bean water in summer can effectively stimulate appetite and have the effects of clearing away heat, promoting diuresis, relieving summer heat, cooling blood and detoxifying. It has a good auxiliary treatment effect on sore throat, sore mouth, dry stool, dry mouth and bad breath. The heat-clearing power of mung beans lies in the skin, and the detoxification power is included. Therefore, if you just want to cool off the heat, wash the mung beans when cooking the soup, and boil them with strong fire for about 10 minutes. The soup cooked in this way is green and clear, and has the best effect of cooling off the heat.

　　In addition, cooking mung bean soup with other ingredients will also produce good health effects. For example, mung bean double flower soup: choose 100 grams of mung bean and 10 grams of honeysuckle, and decoct them with water. You can also add Coicis Semen for invigorating spleen and eliminating dampness to make Coicis Semen and mung bean soup, and add Lily for nourishing yin and moistening lung to make Lily and mung bean soup. It should be noted that mung beans are cool, and people with weak constitution and cold are not suitable for drinking. In addition, mung bean also has detoxification function. Therefore, if the drugs taken by patients, whether traditional Chinese medicine or western medicine, contain organic phosphorus, calcium, potassium and other components, mung bean will combine with these components to form a precipitate, thus decomposing the efficacy and affecting the treatment.
