The meaning and characteristics of the summer solstice solar terms What does the summer solstice solar terms mean?
The summer solstice is the earliest solar term among the 24 solar terms. In the 7th century BC, the ancestors used Tugui to measure the sun's shadow, which determined the summer solstice. The annual summer solstice begins on June 2nd1day (or 22nd) and ends on July 7th (or 8th). According to the Transcript of Compliance with the Constitution: "The sun arrives in the north, the day is long, and the shadow is short, so it is called the summer solstice. To the best, it is extremely good. " On the day of the summer solstice, the sun's direct exposure to the ground reaches the northernmost point of the year, almost directly to the Tropic of Cancer (23 26' north latitude), and the days in the northern hemisphere reach the longest, and the days get longer as you go north. For example, the day length in Haikou, Hainan is a little more than 13 hours, in Hangzhou it is 14 hours, in Beijing it is about 15 hours, and in Mohe, Heilongjiang it can be more than 17 hours. After the summer solstice, the position of the direct sunlight on the ground gradually moved southward, and the daytime in the northern hemisphere shortened day by day. There is a folk saying that "eating noodles on the summer solstice makes a day shorter". At this time, the southern hemisphere is in the middle of winter.
The Summer Solstice was also called "Summer Festival" and "Summer Solstice Festival" in ancient times. The summer solstice falls around June 2 1 of the Gregorian calendar every year, and the sun begins when it reaches 90 degrees of the yellow meridian. On the day of the summer solstice, the sun reaches the northernmost point of the year directly, almost directly to the Tropic of Cancer (23 26' 28' 44 north latitude). The daylight in the northern hemisphere is the longest, and the farther north it is, it is the longest day in the northern hemisphere, and most places in the south are around 14h from sunrise to sunset. In ancient China, the summer solstice was divided into three phases:
"A wait antlers solution; Second, wait for cicadas to start singing; Three waiting for Pinellia ternata. "
Although mi and deer belong to the same family, the ancients believed that they belonged to yin and yang. Deer's horns face forward, so they belong to Yang. On the summer solstice, yin qi is born and yang qi begins to decline, so the positive antlers begin to fall off. Because mi belongs to yin, it falls off at the corner of the winter solstice; After the summer solstice, male cicadas flapped their wings and sang because of the feeling of yin qi; Pinellia ternata is a shade-loving herb, so it is named because it was born in a swamp or paddy field in midsummer. It can be seen that in the hot midsummer, some yin-loving creatures began to appear, while positive creatures began to decline.
In our country, people divide 15d after the summer solstice into three "hours", generally the first hour is 3d, the middle hour is 5d, and the last hour is 7d. During this period, the temperature in some parts of China is high, the sunshine is sufficient, and the crops grow rapidly. Although the summer solstice has the longest day and the highest sun angle, it is not the hottest time of the year. Because the heat near the surface is still accumulating at this time, and it has not reached the maximum. As the saying goes, "The heat is in the dog days", and the real hot weather is calculated based on the summer solstice and beginning of autumn. From mid-July to mid-August, the temperature in all parts of China is the highest, and the highest temperature in some areas can reach about 40℃.

What should I pay attention to?
What should we pay attention to when eating on the summer solstice?
Slightly sour, antiperspirant and exterior consolidation.
Because the summer solstice sweats more, the loss of salt is greater, and electrolytes such as sodium in the body will also be lost. Therefore, in addition to supplementing salt, you need to use some foods with sour taste.
Traditional Chinese medicine theory holds that more foods with sour taste should be eaten before and after the summer solstice to achieve the effect of consolidating the exterior and stopping sweating. There is such a description in the Yellow Emperor's Internal Classic Su Wen, "The heart governs summer, and the heart is bitter and slow, and it is urgent to eat acid to collect it." That is to say, the acidic foods that need to be eaten in summer are Cornus officinalis, Schisandra chinensis, gallnut, ebony, etc. These foods can not only produce saliva, remove fishy smell and relieve boredom, but also increase appetite.
Cold noodles for heatstroke prevention and health protection
The arrival of the summer solstice means the beginning of hot summer, and people in many places will choose to eat cold noodles to relieve the heat. Southerners generally eat sesame oil mixed noodles, Yangchun noodles and crossing the bridge deck, while northerners mainly eat noodles with gravy and Zhajiang Noodles.
Cold noodles have the effects of heatstroke prevention, cooling and hunger relief, and are rich in essential nutrients such as starch, crude fiber and vitamins, which are very beneficial to the human body. However, it should be noted that the content of protein in cold noodles is less, so some meat, bean products, eggs and so on should also be properly matched.
Pay attention to hygiene and prevent "disease from entering the mouth"
Around the summer solstice, all kinds of pathogenic microorganisms grow and reproduce relatively fast, so food is very easy to rot and deteriorate. In addition, at this time, the defense ability of human intestine becomes weak, and it is very vulnerable to bacterial invasion, so the phenomenon of disease from mouth to mouth occurs from time to time.
Pay attention to the following points in diet: try not to leave leftovers; Avoid excessive consumption of cold drinks; Do not eat expired, unmarked and damaged food; Do not eat or eat less mala Tang, cold dishes or cooked food sold by roadside stalls; Do not eat raw and pickled aquatic products; Eat more "sterilized" vegetables, such as garlic, onion, green onion, leek, green garlic and garlic seedlings.
