Climatic characteristics of summer solstice
1, rainstorm weather
During the summer solstice, the temperature is high, the sunshine is sufficient, the crops grow rapidly, and the physiological and ecological water demand is high in most parts of China. At this time, 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 pose a threat to people's lives and property. Attention should be paid to strengthening flood control.
2, Jianghuai Meiyu
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.
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 gradually moved southward, the days in the northern hemisphere became shorter and the nights became longer. 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.
Diet custom of solar terms in summer solstice
1, hot surface
Eating hot noodles in hot summer is called "picking pots", which is said to mean "eliminating disasters". Eating hot noodles is to drive away evil spirits, and sweating more to drive away moisture and summer heat in the human body.
2. Summer solstice soup
People in Changsha, Hunan, eat dumplings made of glutinous rice flour and mouse grass on the summer solstice, which is called "summer solstice soup". As the saying goes, "after eating the summer solstice soup, the muddy stone steps become pits." "Eat a ball and cross the river with one foot on the summer solstice" means that you are extremely powerful and as light as a swallow.
3. Summer solstice cake
After the summer harvest, new wheat comes on the market, so it is a custom to eat noodles and try new wheat every day. Some people mix them with wheat flour and spread them into pancakes for baking cooked food. With vegetables, pods, tofu and bacon, it is usually called "summer solstice cake" after ancestor worship.
4. Litchi
Cantonese in Guangzhou and Qinzhou and Yulin in Guangxi both like to eat dog meat and lychee on the solstice in summer. Are they not spicy together? Eating a lot of litchi is easy to cause hypoglycemia, that is, "litchi disease", so it must be moderate. Drinking a little salt water or mung bean water, wax gourd water and rehmannia soup before and after eating litchi can relieve summer heat.

According to the custom of old Beijing, lettuce and cold noodles can be eaten as early as the solstice of summer every year.

8. Amaranth and gourd
In some areas, during the summer solstice, underage nieces and nephews will go to their mothers' homes for dinner, and uncles' homes will prepare amaranth and gourd for cooking, which means that eating amaranth will not cause diseases, and eating gourd legs will give them strength.
9. Summer solstice eggs
Hengyang, Chenzhou, Yongzhou and Xiangxi in southern Hunan eat eggs from summer solstice. On the summer solstice, the whole egg is cooked, peeled and cooked with red dates, which is called "eating summer solstice eggs". In southern Hunan, it is mainly Jiahe, Lanshan and Guiyang who get up in the morning of the summer solstice, cook the whole egg, dye the skin of the egg with red paper or red dye, put it in a small net bag and tie it on the chest of children until noon or afternoon, then peel off the eggshell and eat the egg. People think that eating eggs in summer solstice can strengthen the body, strengthen the stomach and keep pace. As the saying goes, "Eat eggs in summer solstice, and the slate is trampled."
Summer solstice health tips are simple.
1, 2000 ml of water every day to prevent headache and dizziness.
During the summer solstice, most people will have symptoms of drowsiness, fatigue, headache and dizziness, which may seriously affect their daily life and work. The reasons are as follows: firstly, due to the high temperature in this season, the human body can only dissipate heat by sweating, resulting in a large amount of water loss. At this time, if the water is not replenished in time, the blood volume of the human body will be reduced, and the blood supply to the brain will be insufficient, which will lead to headache and dizziness. Another cause of headache and dizziness is that when people sweat, the blood vessels on the body surface will expand and more blood will flow to the body surface. This redistribution of blood can make people with low blood pressure lower, thus causing headaches and dizziness.
2. Rest and adjust your heart.
According to the five elements theory of traditional Chinese medicine, summer is the season of nourishing the heart. Ji Kang, a pianist from the Three Kingdoms, is a famous heart-nourishing scientist. He believes that it is more appropriate to take a breath and calm down in hot summer, which should be "often like ice and snow", that is, "calm down and naturally cool". Listening to slow music is a good way to adjust your breathing. The notes in music also contain elements of yin and yang and five elements. Contrary to the effect that fast-paced music can enhance the yang in the body and help people get excited, soothing music can help slow down breathing and rest the heart.
Step 3 be cool
This refers to clothing and living environment. Don't wear thick clothes in summer. Many young people like to wear cowboy clothes, which are not suitable for summer. The color of clothes should be mainly light, so as to absorb less heat. Try to choose cotton and linen as the fabric of clothes, which is easy to absorb sweat and breathe. The room should be cool, and the indoor temperature is low in the morning and evening. Doors and windows should be opened for ventilation. At noon, the outdoor temperature is higher than the indoor temperature. Close the doors and windows and close the curtains. A cool environment will make people feel calm and safe.
4, mung bean wins the ice and relieves summer heat
People in China like to drink mung bean porridge which has been passed down for hundreds of years in summer, which is a good way to cool off the heat. Mung beans are sweet and cold, and can enter the heart meridian and stomach meridian. It is best to urinate in Huangchi in summer. Many people don't know whether to remove the bean skin when cooking mung beans. In fact, mung bean coat is also a blind Chinese medicine, with the same effect as mung bean, but slightly weaker. Therefore, as a general heat-clearing product, there is no need to deliberately remove the bean skin. People who like sweets can also add some honey, which also has a good effect on carbuncle caused by heat toxicity. But mung beans are cold after all, and people with weak constitution should not eat more. Long-term service will turn the deficiency cold in the body into reality, so it will be more difficult to recuperate in the future.
Step 5 Exercise properly
The best time to exercise is in the early morning or in the cool night. The venue can be in rivers, lakes, parks, courtyards and other places with fresh air. Walking, playing Tai Ji Chuan and doing radio gymnastics are the best sports, but strenuous exercise is not suitable.
6. Take sun protection measures when going out.
At this time, the public should avoid being exposed to strong sunlight. When going out, they should take sun protection measures, such as umbrellas, sun hats and sunscreen. Take some Dan, Huoxiang Zhengqi water, ten drops of water and cool oil with you. In addition, from the color of clothing, it is best to wear red clothes, because red clothes can absorb a lot of ultraviolet rays from the sun, thus protecting the skin and preventing skin aging or even cancer.
7. Avoid eating cold food at night
People who have a short summer night, are older, or have a weak constitution often have cold stomachs and indigestion, such as lettuce and melons. It is forbidden in summer, so you should pay special attention to eating this kind of food at night. Also be careful not to eat meat, noodles or anything cold and sticky at night, or you will see bloating, vomiting and diarrhea.
8. Go to bed late and get up early to take a nap
At this time, the daily rest of the public should conform to the changes in nature, and should go to bed late and get up early, while the elderly and infirm should go to bed early and get up early, and try to keep about 7 hours of sleep every day. Starting today, you must take a nap. In the theory of traditional Chinese medicine, taking a nap is to nourish yin with yang, and sleeping for children is to nourish yang with yin. As long as you can close your eyes for a while, you can achieve a good effect of nourishing yin.
9. Take a hot bath
Taking a bath with warm water every day is also a fitness measure worth promoting, which can not only wash away sweat and dirt, but also make the skin clean and cool, relieve summer heat and prevent diseases, and also play a role in exercising. Because water pressure and mechanical massage in warm bath can reduce the excitability of nervous system, dilate blood vessels on body surface, accelerate blood circulation, improve the nutrition of skin and tissues, reduce muscle tension, eliminate fatigue, improve sleep and enhance resistance.
10, avoid lying in the cold at night.
Don't sleep at night and turn on the air conditioner all night. This habit can easily lead to colds, facial paralysis, joint pain, abdominal pain and diarrhea, which is very serious to the body. Don't fan the wind to cool down after the child falls asleep, otherwise it is prone to diseases such as hand and foot convulsions, mouth congestion and arthralgia, and people often don't know its harm. The so-called deep love is very harmful. The proverb "avoid the wind like an arrow, avoid the color like chaos, add and subtract clothes on time, and eat less after meals" can all be understood as the health requirements in summer.
