7th ushered in the "heavy snow" in the 24th solar terms of the lunar calendar. The arrival of the heavy snow solar term marks the beginning of the mid-winter season. After entering the heavy snow solar term, more and more areas in my country will usher in snowfall, and the temperature drops after the snow, and the cold will intensify.
ShiyanWeather | There is no snow when it is heavy snow, and it is getting colder in the morning and evening
Every year, around December 7th, when the sun reaches 4255 degrees of the ecliptic etiology of , it is the "heavy snow" solar term. "High snow is the November Festival, and the snow is soaring here."
The ancients named this solar term "heavy snow" because "snow" is a product of cold and represents cold rainy weather. The characteristics of this solar term are significantly lower, raining or snowing. The name "heavy snow" is a metaphor, which reflects the climate change during this solar term, the active temperature of the cold current drops and the precipitation increases, which does not mean that there is a lot of snow during this solar term. However, after the heavy snow season, the weather will get colder and the possibility of snow increases greatly. Therefore, entering the "heavy snow" solar term indicates that the snow will go from small to large, and the number of snowfall days and snowfall will increase compared with the light snow solar term, especially in areas where strong cold air meets warm and cold air, the snow will fall greatly and the range will be wider.
In ancient my country, heavy snow was divided into three symptoms: "One time the gust does not chirp; the second time the tiger starts to chirp; the third time the litchi is erected." This means that because the weather is cold, the cold bird no longer chirp; this is the peak period of yin energy, the so-called extreme decline, the yang energy has sprouted, and the tiger has begun to be courtship; "litchi" is a type of orchid , and feels the yang energy germinates and sprouts.
"Heavy Snow" is a solar term that reflects the characteristics of the climate. The characteristics of the weather during the Heavy Snow solar term are a significant drop in temperature and an increase in precipitation. During heavy snow season, most parts of China have entered winter, and the lowest temperature has dropped to 0℃ or below. In areas where the cold and cold air confrontation between the frontiers of strong cold air, heavy snow or even blizzards will drop.
Judging from the weather conditions in Shiyan, after entering the "Little Snow" solar term, due to the strong cold air in the north, a cold wave weather process occurred in our city. Light to moderate snow occurred in some high mountainous areas, and light snow also fell in Shiyan urban area. After December, the weather in our city improved and the temperature rebounded slightly. According to meteorological data analysis, on the day of the "heavy snow" solar term, the weather in our city was sunny, and the maximum temperature in some areas could return to above 10℃.
Dressing Guide | Clothes are not better when traveling more
Heavy snow, light snow, rain, Grain Rain, and other solar terms, are solar terms that directly reflect precipitation. The arrival of the heavy snow solar term means that the weather is getting colder and precipitation increases.
There is a saying among the folks in my country: "There is no snow in the light snow, and the sky is full of heavy snow." It means that if there is no snow during the Little Snow solar term, then when it comes to heavy snow, there will be snowflakes flying and flying all over the sky. Meteorological experts introduced that behind this common saying, the experience and wisdom of our working people are reflected. During the Little Snow solar term, the sun usually reaches 240 degrees of ecliptic longitude. At this time, cold air moves southward and the temperature begins to drop. Cold waves and cold air from western Asia are more frequent. Once the water is sufficient and the temperature drops to a certain extent, snowfall will occur. However, it may not necessarily snow during the Little Snow solar term. In this way, the accumulation of water will be delayed until the heavy snow term, and the weather will further become colder and sufficient moisture will cause heavy snow to fly all over the sky. During the heavy snow solar term, the sun reaches 255 degrees of the yellow longitude. At this time, the temperature drops significantly, and the probability of snow is much greater than that of the light snow solar term.
After entering the heavy snow solar term, the cold air will cause the skin to contract, causing poor blood circulation in the epidermis. In addition, the fragility of the body cells, not paying attention to keeping warm can easily catch a cold and damage the body. Therefore, during the heavy snow solar term, citizens can wear down jackets and coats to help keep the cold.
When choosing underwear, it should be close to the body, soft and not irritating. Do not be too tight in the middle layer of clothes and be moderately loose. It is best to have a closed design at the collar, cuffs, waist, ankles, etc. of the outer garment.
It should be noted that the weather is cold during heavy snow, but citizens do not wear more clothes, the better. When the clothes are wrapped tightly, the insulation effect is not obvious, which makes people feel colder. This is because there is very little air between the interlayers of the clothes, and heat conduction is accelerated.
Health tips | Keeping the head and feet warm is very important
After entering the "heavy snow" solar term, the weather begins to become colder, and strong winds and heavy snow will often occur. Therefore, citizens should pay attention to the invasion of wind 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.
Traditional Chinese medicine believes that the head, chest and feet of the human body are most susceptible to cold evil. During the heavy snow solar term, the temperature drops sharply, which can easily induce the attacks of cardiovascular and cerebrovascular diseases and migraine . Cold in the human body will cause sympathetic nerves to excite , and the catecholamine content in the blood will increase, which will cause blood vessels to contract . In addition, the body's sweating volume will decrease, and the blood volume will increase, which will cause blood pressure to increase . For patients with cardiovascular and cerebrovascular disease , warmth in the head, neck and hands is particularly important. In addition, cold can also stimulate the increase in excitability of the human nervous system. The autonomic nerve , which governs the internal organs, is in a state of tension. Under the reflex of the parasympathetic nerve, it causes disorders in the gastrointestinal apoptosis function and increases gastric acid secretion, which in turn stimulates the gastric mucosa or ulcer surface, causing spastic contraction of the stomach, causing the stomach to be ischemia and hypoxia, thereby causing the recurrence of gastric disease. Therefore, during this season, you should pay attention to keeping your stomach warm and dietary care, and eat more foods that warm your stomach and spleen.
heavy snow solar term, the indoor climate is dry and fresh vegetables are reduced, which will cause vitamin B deficiency and induce angular stomatitis . Therefore, you should drink more water and eat more fruits and vegetables in winter. In terms of diet, eat more foods such as garlic, leek, chili, ginger, coriander, onion, yam, longan, , chestnuts and apricot , etc., to help keep warm. At the same time, pay attention to eating less meat, eating more vegetables and warm fruits, and drinking more porridge.
Because indoor and outdoor dryness, the air humidity is very low, so you must drink more water. In addition, during the heavy snow solar term, you should pay attention to maintaining your mood stability and peace, and your daily life and exercise routinely. The days are short and the nights are long. Be careful to lie down early and get up late, do not stay up late, do not get up too early and practice in the morning, "you must wait for the sun."
