When is the summer solstice on 20 17?

In a blink of an eye, we will come to the summer solstice. When we enter the summer solstice, the weather will really start to get hot, and many places, especially the southern region, will start the sultry mode. Due to the high temperature in summer solstice, people sweat a lot, so everyone must pay attention to hydrating in life, preferably light salt water, and prepare for sun protection.

When is the summer solstice on 20 17? Summer solstice is one of the earliest solar terms among the 24 solar terms. Every year on June 2 1 or 22 of Gregorian calendar, when the sun reaches 90 degrees of the yellow meridian, it is the summer solstice. "Solstice" means "extreme", and the summer solstice is also called "long days". After the summer solstice, the direct point of the sun gradually moves southward, and the days in the northern hemisphere will be shorter and the nights will be longer.

On the day of summer solstice, the sun shines almost directly on the Tropic of Cancer, and absolutely (almost) directly at noon, so there will be a short-term phenomenon of "standing without a shadow" on the Tropic of Cancer. At present, there are five signs of the Tropic of Cancer in Chinese mainland, which are distributed in Shantou, Conghua and Fengkai in Guangdong, Guiping in Guangxi and Mojiang in Yunnan.

The summer solstice of 20 17 is June 2 1 day of Gregorian calendar, which is May 27th of the lunar calendar.

Traditional custom of summer solstice: Most areas in China have the custom of eating noodles from summer solstice. In the Qing Dynasty, Pan Rongbi recorded in "Ji Sheng at the Age of Emperor Jing": "It's a Japanese day, and the furniture eats cold noodles, that is, the water surface as the saying goes ... As the saying goes," We eat solstice wonton in winter and solstice noodles in summer. " . ",there is also a folk saying that" after eating the summer solstice, a thread is missing a day ". But they all eat noodles, and different places still have different ways to eat them. Beijingers love to eat Zhajiang Noodles. Stir-fry the sauce first, then cook the noodles, soak them in cold water, and then add the fried sauce to eat. Some people also mix some shredded cucumber, shredded radish and soybean sprouts, which tastes better. In some places in the south, noodles are often made into pancakes and baked with beans, vegetables, tofu and bacon. Sacrifice ancestors first, eat them after they are sacrificed, or give them to relatives and friends.

In some places, it is still a fashion to weigh yourself on this day. It is said that after being weighed on the day of summer solstice, you are not afraid of high temperature and heat. Nowadays, the custom of weighing the summer solstice is rare, but in ancient times, once you were sick, it was difficult to recover quickly. People have a soft spot for the solstice in summer. This also pinned people's good wishes for health and longevity. When weighing, men, women and children lined up to weigh, and some people reported their weight. The scene is very lively, just like a holiday. After weighing, you have to eat wheat rice or wheat grains. How to cook wheat rice? On the night before the summer solstice, women will soak the newly planted wheat in cold water. After soaking overnight, the new wheat will become round. At lunch, mix rice with rice, add some chopped fresh onions and cook in a pot. After boiling, simmer for 20 minutes. This kind of wheat rice is thick and fragrant, so eat it slowly. It's easier to eat wheat. You can directly cook the wheat for the children to eat.

Dog meat is also very popular in many places in Guangdong during the summer solstice. There is a saying: "dogs have nowhere to go from summer solstice." In other parts of our country, people usually eat dog meat in winter, which is considered to have aphrodisiac and warm-keeping effects. Moreover, they believe that eating dog meat in summer solstice can also ward off evil spirits, strengthen the body and resist the plague. There is a saying that can express their point of view very well: "After eating the dog on the solstice in summer, the west wind spreads eastward." In other words, as long as people eat dog meat from summer to day, their bodies can resist the attack of cold wind and heavy rain, and they will catch fewer colds and be healthy.

Characteristics of three stages of summer solstice

In ancient China, the summer solstice was divided into three phases: "the first phase of antlers decomposition; Second, wait for cicadas to start singing; Third-class Pinellia ternata. " Although Mi and Lu belong to the same family, the ancients thought they belonged to Yin and Yang. The deer's horn faces forward, so it belongs to Yang. On the solstice of summer, Yin Qi was born, and Yang Qi began to decline, so the front antlers began to fall off. Because mi belongs to yin, it falls in the corner of winter; After the solstice of summer, the male cicada fluttered and sang because of Yin Qi's feeling; Pinellia ternata is a shade-loving herb, named after it was born in swamps or paddy fields in midsummer. It can be seen that in the hot summer, some yin-loving creatures began to appear, while positive creatures began to decline.

Climatic characteristics of summer solstice 1 rainy season

Summer solstice season is the "Meiyu" season in Jianghuai area. At this time, it is the ripe period of plums in Jiangnan, and the air is very humid. Cold and warm air masses meet here, forming a trough of low pressure, leading to rainy weather. In this weather, the utensils are moldy and the human body feels uncomfortable. Some mosquitoes breed quickly, and some intestinal bacteria are easy to breed. At this time, we should pay attention to drinking water hygiene and try not to eat cold food to prevent the occurrence and spread of infectious diseases.

2. Convective weather

After the summer solstice, the ground is heated strongly and the air convection is strong, and thunderstorms are often easy to form in the afternoon to evening. This kind of hot thunderstorm comes and goes, and the rainfall range is small. People call it "dividing fields in summer and rain". Liu Yuxi, a poet in the Tang Dynasty, skillfully used this weather to write a famous poem, "The east rises and the west falls, and the road is sunny and sunny." The heavy precipitation brought by convective weather is not always as beautiful as described in the poem, and it often brings local disasters.

3. High temperature sauna

Like the winter solstice, the summer solstice is also a solar term reflecting the changes of the four seasons. Astronomy stipulates that the summer solstice is the beginning of summer in the northern hemisphere. After the summer solstice, although the direct point of the sun began to move southward from the Tropic of Cancer, the days in the northern hemisphere became shorter and the nights became longer. For the Tropic of Cancer and its northern area, the height of the sun at noon is also decreasing day by day. However, because the heat radiated from the sun to the ground is still more than the heat radiated from the ground to the air, the temperature will continue to rise in the future, so there is a saying that it is not too hot from summer to the sun. According to the data of 195 1 to 2006, the historical extremes of many cities in the north appeared after the summer solstice.

3. Rainstorm weather

In most cases, during the "summer solstice" period, the middle and lower reaches of the Yangtze River and the Jianghuai basin are rainy and frequently rainstorm, which is easy to cause floods and even threaten people's lives and property. Attention should be paid to strengthening flood control work. After the summer solstice, relevant departments should pay attention to the adverse effects of rain on transportation and tourism, and do corresponding preventive work; Please walk slowly and carefully on the way to work, and pay attention to the road conditions and weather changes in time.

What food is good to eat on the solstice in summer? 1, vegetables

First push: bitter gourd

Optional food: tomato, eggplant, celery, asparagus and lotus root.

Bitter food is the natural enemy of fire. Bitter food is bitter because it contains bitter substances such as alkaloids and urea. The best bitter food is bitter gourd. Whether it is cold salad, stir-fry or soup, as long as it can be cooked well, it will not lose its "blue color". Except bitter gourd, boiled tomatoes, eggplant and celery can achieve the purpose of "removing fire". Cold salad and salad are also easy to refresh the food.

2. Fruit

First choice: watermelon

Substitution: grape pear, hawthorn, apple, litchi

Watermelon pulp is rich in lycopene, carotene and vitamin C, while melon seeds are rich in vitamin E and trace elements such as zinc and selenium. When watermelon pulp and melon seeds are made into juice, you can get a good drink to quench your thirst and cool off the heat. Grapes, pears and other fruits are rich in water and calcium, potassium and magnesium salts, which can moisten the throat and make people feel refreshed and comfortable.

3. Meat

First choice: duck meat

Substitution: crucian carp, chicken and pigeon meat.

Duck meat is cold, rich in protein, and because it belongs to waterfowl, it can nourish the stomach, promote fluid production and soften blood vessels whether cooking porridge or soup, so it is a rare cool food in meat. Many people eat too lightly in pursuit of cooling off summer heat, which leads to insufficient intake of protein and weak constitution. In fact, crucian carp, chicken and loach, including lean meat, all have the function of clearing away heat and relieving summer heat, and can be safely eaten. However, mutton, beef, dog meat and other hot foods need to be selected in moderation.

4. beans

First choice: mung bean

Substitution: bean sprouts, tofu, soybean milk, red beans and black beans.

Mung bean soup is a traditional folk food for relieving summer heat in China. Take mung bean100g, add water1000ml, and decoct to get liquid for drinking (appropriate amount of sugar can be added). The heat-clearing function of mung beans lies in the skin, and the detoxification function is among them. Therefore, if you just want to cool off the heat, wash the mung beans when cooking soup and cook them on high fire for about 10 minutes. Be careful not to cook for too long. The soup cooked in this way is relatively green and clear, which has a good effect of relieving summer heat.

Precautions for health care in summer: Eat more melons until the day (1): The temperature in summer is high, and the human body loses more water, so it is necessary to replenish water in time. The water in vegetables is natural, clean, nutritious and bioactive water filtered by multi-layer biofilm. The water content of melons and vegetables is above 90%. All melons and vegetables have the function of lowering blood pressure and protecting blood vessels.

(2) Eat more cool vegetables: Eating some cool vegetables is conducive to promoting fluid production to quench thirst, relieving summer heat, clearing away heat and purging fire, and detoxifying and relaxing bowels. Cucumber vegetables, except pumpkin, are warm, and others, such as bitter gourd, towel gourd, cucumber, melon, watermelon and wax gourd, are cool. Tomatoes, celery and lettuce are all cold vegetables.

(3) Eat more "sterilized" vegetables: Summer is a season of frequent human diseases, especially intestinal infectious diseases. Eating more "sterilized" vegetables can prevent diseases. This kind of vegetables include: garlic, onion, leek, green onion and so on. These onion and garlic vegetables are rich in broad-spectrum fungicides, which can kill and inhibit various cocci, bacilli, fungi and viruses. Among them, the most prominent role is garlic, which is best eaten raw.

At the same time, we should also pay attention to supplement some nutrients:

(1) Supplement sufficient vitamins, such as eating more fresh fruits and vegetables such as tomatoes, green peppers, wax gourd, watermelons, bayberry, wax gourd, peaches and pears;

(2) supplement water and inorganic salts, especially pay attention to the supplement of potassium. Beans or bean products, fruits and vegetables are all good sources of potassium. Eat more foods that clear away heat and promote diuresis, such as watermelon, bitter gourd, peach, ebony, strawberry, tomato and cucumber.

(3) Appropriate supplementation of protein, such as fish, lean meat, eggs, milk and beans, is the best quality protein.

Everyone should pay special attention to diet and daily life. Although the temperature will be higher at this time, you'd better eat less particularly cold food. In this case, it is very bad for the stomach.
