On December 7 or 8 every year, when the sun's yellow longitude reaches 255 degrees, it is one of the 24 solar terms' heavy snow '. So what's the meaning of the heavy snow solar term? Today, let's learn about it with Xiaobian. Today is 24 solar terms of snow, snow solar terms health precautions must be collected.
Heavy snow, as the name suggests, has a lot of snow. The ancients said: 'big, Sheng also, so far and snow Sheng also'. At this time, snow often falls in a wide range, so it is called heavy snow.
Snow is the twenty-first solar term of the twenty-four solar terms and the third solar term in winter. In the snow season, snow falls more widely, which often shows the scene of snowflakes falling one after another. Every year, on December 7 or 8 of the Gregorian calendar, heavy snow is delivered. On this day, the sun moves to 255 degrees of the Yellow longitude. At noon, the shadow is measured with a guibiao. The shadow length is one foot, two feet and four quarters of the ancient ruler, which is equivalent to 3.05 meters today. At night, the handle of the Big Dipper pointed to the direction of Hai, that is, to the northwest. This stage is generally in November of the lunar calendar, also known as the zhongdongyue, Jiayue, Changyue.
"Snow capped rivers, snow capped mountains.". During the heavy snow season, the amount of snow gradually increases, the number of days of snow also increases, the temperature continues to fall for one year, and there is snow on the ground.
Three times of heavy snow. "At the beginning of the season, the bundan doesn't sing". Bundan is a kind of bird that cries for the Dan at night. At this time, the bird also holds its breath and holds its voice, and can't escape from the nest. 'the second time the tiger begins to cross', when the tiger is in estrus, it will start to mate and reproduce. "Three seasons of litchi" is a kind of tiny grass, which sprouts in the sunny place in the cold winter.
Heavy snow climate
What does the solar term snow mean
In heavy snow season, except for the winter areas in South China and South Yunnan, China's vast land has been covered with winter costumes. The average temperature in Northeast and Northwest China has dropped to - 10 ℃, and the temperature in the Yellow River Basin and North China is also stable below 0 ℃. In the years with normal climate, snow has appeared in the Yellow River Basin and the north area, and the growth of winter wheat has stopped. After the heavy snow, the temperature of Jiangnan has dropped significantly in the winter, and freezing often occurs. The fact that 'basket water does not leak after the heavy snow winter solstice' is the true portrayal of this time, but some years are not always the same, the temperature is high, and there is no freezing phenomenon, which often results in more rain in the later period. Wheat and rape are still growing slowly in Jianghuai and the south of the Yangtze River. We should pay attention to the application of fertilizer, so as to lay a good foundation for safe winter and spring growth. When the wheat in South and southwest China enters the tillering stage, the tillering fertilizer should be applied in combination with the middle ploughing, and attention should be paid to the ditch clearing and drainage of winter crops. Although the weather is cold at this time, the stored vegetables and potatoes should be inspected frequently and ventilated timely. Do not seal the cellar too tightly to avoid overheating and excessive humidity leading to rotten cellar. Keep the temperature as low as possible without freezing damage.
Snow solar term regimen
Pay attention to warm supplement in daily diet during heavy snow season.
We can eat more beef, rabbit and mutton, which are considered by traditional Chinese medicine to be warm, which is helpful to enhance the cold resistance of the body. For people with cold constitution, when cooking these meats, they can also put some auxiliary ingredients such as onion, garlic, ginger, pepper, etc. to improve the warming effect of these meats. But for those who are easy to catch fire, when cooking these warm meat, it's best to add white radish to prevent catching fire. In addition, this season can also eat more walnuts, black sesame, orange and other food, can also play the role of warm tonic.
Heavy snow solar terms will supplement Yang according to their own conditions. People with Yin deficiency, such as red face, dry mouth, chapped lips, dry skin and dry hair, should mainly prevent dryness, protect Yin, nourish kidney and moisten lung. They can eat soft and sweet food, such as milk, soymilk, egg, fish, sesame, honey and Lily. They should avoid hot and dry food, such as pepper, anise and fennel. If you are often pale, weak, tired and cold, you should eat warm, cooked soft food, such as beans, dates, yam, longan meat, pumpkin, leek, celery, chestnuts, chicken, etc., and avoid sticky, dry, hard, raw and cold food.
Cold weather prevention, daily routine and mood stabilization
We should pay attention to the invasion of wind evil and cold evil, especially the head and feet. This is because the occurrence of some diseases has a lot to do with not paying attention to keeping warm. According to traditional Chinese medicine, the head is the meeting of all Yang. The cold weather will constrict blood vessels, and people will have headache and dizziness. For cerebrovascular patients, cold is easy to induce cerebrovascular disease. So it is very important to keep your head warm. In addition, as the saying goes, 'cold starts from the foot', blood supply is slow and little at the farthest distance from the foot to the heart, subcutaneous fat layer is thin, and the warmth preservation is poor. Once suffering from cold, it will reflexively cause the contraction of respiratory mucosa capillaries, and reduce the resistance to disease, resulting in upper respiratory tract infection. Therefore, attention should be paid to the warmth preservation of the feet during the snowy season.
At the same time, we should pay attention to the rule of daily life.
Due to the short days and long nights in winter, we should pay attention to sleeping early and getting up late, not staying up late, not getting up early and exercising in the morning. We should do "must stay in the sun". In addition, the metabolism level of human body is relatively slow in winter, and Yin, essence and Yang Qi are all in hiding. Therefore, we should pay attention to the sufficient preparation activities during exercise, and then take off the coat after the heat, and do not exercise too much to avoid sweating; after exercise, put on dry clothes. In addition, the degree of indoor air pollution in winter is dozens of times more serious than that of outdoor air. It is necessary to open doors and windows frequently for ventilation, so as to clean the air and refresh the mind.
