Dog days, what to eat? Master five key points: proper nutrition, sweet and sour taste, invigorating qi to remove fire, replenishing water for health, refreshing and clean.
A. Appropriate nutrition supplement: In dog days, there is an old saying among the people: "In dog days, jiaozi lies on his head, noodles lie on his feet, and pancakes roll eggs". In the past, eating jiaozi, pancakes and noodles in dog days not only meant the joy of abundant food after harvesting wheat in summer, but also reminded people not to make do with their diet in dog days. Eat more foods rich in protein and B vitamins. Due to the high temperature, excessive sweating and high consumption in summer, the human body will lose a lot of protein, a lot of B vitamins and minerals such as potassium and sodium, so it should be supplemented appropriately. For example, chicken, duck, pork and fish are all summer supplements. Duck meat is especially cool, which has the functions of nourishing yin and stomach, invigorating spleen and tonifying deficiency, promoting diuresis and infiltrating dampness, and is especially suitable for people suffering from bitter summer, excessive internal heat and body heat. Traditional Chinese medicine believes that milk is slightly cold, which can play the role of "removing fire" by nourishing yin, clearing away heat and detoxifying. Soybean is sweet, flat, and enters the spleen and intestines. It has the effects of invigorating spleen, widening middle energizer, moistening liver, promoting diuresis, clearing away heat and toxic materials, and benefiting qi, and contains a lot of protein, vitamins and dietary fiber. Moreover, milk and soybean milk contain more than 70% water, which can supplement the water lost by sweating in summer.
B. more acid and more sweetness: ancient scholars thought that "summer heat and dampness should be clear." It is hot in summer, people like cold drinks and drink plenty of water, which causes moisture to invade the human body, while external moisture enters the body, which makes the water wet and sleepy the spleen, reduces the function of the spleen and stomach, and causes digestive dysfunction and loss of appetite. According to the viewpoint of TCM health preservation, dryness and dampness in summer are very unfavorable to the spleen, so it is advisable to eat more sweet flavor in daily diet. Such as yam, coix seed, cowpea, lentil, soybean, carrot, taro, sweet potato, potato, pumpkin, meatball, chestnut, etc. Traditional Chinese medicine believes that the taste of nature is sweet to the spleen, and it is beneficial to replenish the spleen with foods that strengthen the spleen and promote diuresis. In addition, summer belongs to the heart, and the heart likes to be cold. Eating more sweet and sour in dog days is good for your health. Such as: pineapple, strawberry, orange, watermelon, peach, etc.
C. Supplementing qi to eliminate fire: In hot summer, the yang rises, sweating is more in summer, and qi is also lost with the loss of sweat. The more you sweat, the more gas you lose! Therefore, people will become listless, tired and weak, which is what Chinese medicine says: "The loss of qi with body fluid is easy to lead to excessive internal heat, which is manifested as irritability, anxiety, excitability and insomnia. Especially in patients with respiratory tract, they often feel short of breath, and their chest tightness and shortness of breath are aggravated. Therefore, invigorating qi and eliminating fire is also a principle that should be paid attention to in summer health preservation. A good product for invigorating qi, such as American ginseng, can nourish yin, promote fluid production and remove fire, and can be used as a substitute for tea. For example, American ginseng chrysanthemum tea can not only replenish qi but also clear heat. In addition, there are many foods that can replenish qi, such as yam, jujube, soybean, chicken, pork, beef, crucian carp, carp and eel. Lentils and coix seed have good effects of invigorating spleen and promoting diuresis, and they are the best food for patients with spleen deficiency in summer. There are many foods that can reduce internal heat in summer, such as bitter gourd, bitter chrysanthemum, tomato, cucumber, lettuce, watermelon, and cool fruits and vegetables in summer.
D. hydrating for health: Chinese medicine theory says "yin and yang and five elements" and "harmony between man and nature". Winter is cloudy, summer is sunny, and summer is the season when the sun is strong, that is to say, the sun is strong in summer, and the cold in the body is in a state of easy solution. In dog days, people will sweat a lot when they are working or exercising a little, and then they will have a strong thirst. When the human body loses a lot of water, salt can cause dizziness, fatigue and even heatstroke, which is very unfavorable to health, especially for people with chronic diseases. Therefore, paying attention to hydration in dog days has become the top priority of health care.
E. fresh and clean: Chinese medicine believes that the stomach is the foundation of the day after tomorrow. In summer, people often feel loss of appetite, and the function of spleen and stomach is relatively slow. At this time, they can eat more fresh fruits and vegetables. Fresh fruits and vegetables are rich in vitamins, cellulose and sugar, which can not only effectively supplement the necessary energy, water and vitamins, but also greatly increase people's appetite because of their refreshing characteristics. It is more conducive to the improvement of anorexia caused by dampness in summer. More importantly, when eating fruits and meat in summer, we should pay special attention to food hygiene. For people with poor spleen and stomach, don't be greedy and cold, so as not to get dysentery and diarrhea, which will do harm to the body.
■ Three-volt stickers: Huangdi Neijing says that in the dog days, the yang is extremely abundant, the yin begins to generate, the meridians are unblocked, and qi and blood are driven to the body surface. In the dog days of summer, the temperature is high, the yang is generated, and the human skin is slack, which is conducive to drug absorption. According to the characteristics of acupoints related to different diseases in human body, the method of warming yang is adopted. Regulate the balance of yin and yang in the body and the function of zang-fu organs, replenish human yang, increase the body's disease resistance, and achieve the purpose of preventing winter from coming. If you have chronic respiratory diseases, you can apply it continuously for three years. It has certain disease prevention effect.
■ Correct use of air conditioning; In dog days, the temperature and humidity are relatively high. In order to adjust the ambient temperature, the human body needs to open and close sweat pores in time to expel excess damp heat from the body. However, when we suddenly enter a low-temperature room from the scorching sun, or stay in an air-conditioned room for a long time, the sweat pores that normally excrete sweat will suddenly or continuously close, leading to the interruption of normal perspiration function. The air conditioning in the body is turned off together. As we all know, sweating is a detoxification process of the human body. In summer, with the help of the external yang, the human body should excrete all kinds of cold-dampness toxins from the body. Due to the cold in the body, there will be muscle pain, joint pain, headache, no sweat, loss of appetite, and even chills and fever. Symptoms such as wind, heat, summer, dampness and cold appear, and even the original respiratory diseases are alleviated, and symptoms such as fever, cough and excessive phlegm appear.
In addition, in the summer when epidemic prevention and control is normalized, we must pay attention to hygiene and disinfection when using air conditioners to avoid the spread of bacteria and viruses.
■ How to exercise in summer? "Practicing three or nine in winter and three days in summer" is the experience summarized by predecessors in the long-term exercise process. Although there is some scientific truth, it varies from person to person. For the elderly and people with weak constitution, especially those with respiratory diseases, asthma patients are not suitable. Dog days are the hottest season in a year, with high temperature, low air pressure, high humidity and low wind speed. This climatic condition has obvious adverse effects on human health. When the maximum temperature is between 30 and 33 degrees Celsius, the elderly should reduce the amount of exercise and avoid strenuous exercise. It is advisable to exercise for less than half an hour every day. With the dog days coming, the elderly should do some slow exercises according to their own physical strength, such as walking slowly, doing exercises, Tai Ji Chuan, Baduanjin, six-character tactic and so on, which are all helpful to health.
Summer is hot, and under the prevention of epidemic normalization, I hope you can master these health principles and spend the summer safely and healthily.
