□ Our reporter Cui Hong
At 10:39 today, the "big cold" of the twenty-four solar terms is coming to "report"!
Winter is coming to an end, and there are vague signs of spring.
The season of "Great Cold" is a busy and cheerful solar term when it is time to bid farewell to the old and welcome the new.
During the "big cold" season, everyone has to be busy with work, and also need to clean and dust to prepare for the New Year. Medical experts remind citizens and friends to try their best to go to bed early and get up late, and exercise after sunrise to maintain a good mood.
The temperature was below freezing yesterday
Cold, so cold, so cold.
Yesterday, with the arrival of cold air, the provincial capital not only ushered in the long-lost snowflakes, but the whole day was shrouded in gloom and the temperature did not exceed 0°C.
Just a few days after entering 49, Tiangong changed his previous warm appearance.
Yesterday morning, the sun did not show a bright smile like the previous days. On the contrary, under the control of the cold air, the sky over the provincial capital was overcast and foggy.
At about 9 o'clock, scattered small snow particles fell from the sky, hitting pedestrians' clothes and faces.
Over time, the snow particles turned into small flakes, which fell gently into the night.
Snow Maiden is not very powerful, and basically disappears after falling to the ground. Only the snow Maiden can be seen in cars and in the square with few pedestrians.
In the gloomy and cold atmosphere, the temperature in the provincial capital was always below freezing yesterday, with a maximum of only -0.4 ℃.
It is precisely because of the low temperature that some roads in the urban area are icy. Whether walking, cycling or driving, people are cautious, which really answers the phrase "walking on ice in three, nine, four, nine".
In order to resist the cold, the citizens wrapped themselves tightly, with hats, scarves, and masks, with only one pair of eyes showing.
Xiaoxue is accompanied by "big cold" today
"When it's cold, it's three, four, nine, and it's cold to walk on the ice." Today, we usher in the "big cold" solar term.
Like "Small Cold", "Great Cold" is also a solar term that indicates the degree of cold weather, and is the last of the twenty-four solar terms; after "Great Cold", it will usher in the new year's solar term cycle.
It is understood that on January 20 or 21 of the Gregorian calendar every year, when the sun reaches 300 degrees ecliptic longitude, the "Great Cold" solar term begins.
Although the cold waves are frequently heading south at this time, strong winds and snowfall make the weather cold from time to time, but the earth is quietly warming up.
This means that the harsh winter is coming to an end and spring is coming.
However, the provincial capital is still a long way from spring.
The "big cold" is here, what's the weather like in the provincial capital?
The answer is "very fitting".
According to the monitoring of the Municipal Meteorological Observatory, it is expected that during the daytime, the provincial capital will have sporadic light snow and become cloudy, and the maximum temperature is only -1℃.
In the evening, it will be cloudy and overcast, with sporadic light snow in the western mountainous areas, the minimum temperature is -3℃, and the northern area may drop to around -10℃.
Tomorrow, Snow Maiden, who has just rested for a day, will come again. The temperature is basically the same as today, and the severe cold will continue to accompany everyone.
Therefore, experts remind citizens and friends to keep warm and cold when going out, and pay attention to safety at the same time.
Who is colder "big cold" or "small cold"
People often say that "the big cold happens every year, not on the third day but on the fourth day". The implication is that the "big cold" is already very cold.
In fact, "Great Cold" is only opposite to "Minor Cold". They are both solar terms that characterize the degree of cold weather. In some areas, the temperature of "Great Cold" is not lower than that of "Minor Cold". a trend.
"Shi Shi Tong Kao Tian Shi" quoted "San Li Yi Zong" as saying: "The big cold is the middle, and the upper shape is the small cold, so it is called the big... The opposite of the cold, so it is called the big cold." At this time, the cold wave Frequent southward trips are the coldest period of the year in most parts of our country, with strong winds, low temperatures, and undisturbed snow on the ground, presenting a severe cold scene of icy sky and snow, and freezing weather.
Since they are both "cold", which one is colder, "big cold" or "small cold"?
In this regard, experts explained that the so-called "small cold" is compared with the last solar term "big cold". "Cold" indicates that the cold season of the year has entered. At this time, the cold air has accumulated for a long time, but not yet It reaches the coldest level, so it is called "small cold".
In fact, judging from the historical meteorological records of most parts of our country, "Minor Cold" is colder than "Great Cold", and it is the coldest solar term in the whole year.
Because, in the middle of winter, "March 9" is basically in the solar term of "Xiao Han", so "Xiao Han" does not live up to the name of "Cold on March 9".
This is because in the last solar term "Winter Solstice", the surface receives less sunlight and less heat, but there is still heat supplemented by deep soil, so the "Winter Solstice" season is not the coldest time of the year.
After the "Winter Solstice" and around the "March 9th", the heat in the deep soil is also exhausted. Although the sunlight and heat increased slightly, it still could not make ends meet, so the lowest temperature in the whole year appeared.
However, some experts have classified the south and the north and found that the southern region is generally colder when it is "minor cold", accounting for 77%; "big cold" is colder, accounting for 13%.
In the northern region, the proportion of "Xiaohan" is colder by 45%, and the proportion of "big cold" is colder by 50%.
Therefore, in the north, the coldness of "Great Cold" wins slightly.
Go to bed early and wake up late to feel comfortable
During the "big cold" season, precipitation is scarce, and there are often cold waves and strong winds, and the climate is relatively dry.
So, how do you stay healthy at this time?
Bi Xiuxia, director of the Department of Traditional Chinese Medicine of the Fourth Hospital of the City, suggested that keeping warm and avoiding colds are the primary "tasks", especially for elderly people suffering from cardiovascular and cerebrovascular diseases, chronic bronchitis or emphysema to survive the winter.
At the same time, you should go to bed early and get up late to keep your mood comfortable.
Bi Xiuxia said that in terms of solar terms, the Great Cold is in the middle of "April 9th" and "May 9th". At this time, the cold wave is frequent to the south, and most parts of our country show a continuous "clear and cold" trend.
From the point of view of traditional Chinese medicine, in autumn and winter, it is necessary to nourish yin and store yang, and in cold winter, we must pay more attention to the collection of yang.
Therefore, she recommends exercise after sunrise.
"Winter activities and exercise are of special significance for health preservation." Bi Xiuxia said that sports in the cold season can be divided into indoor and outdoor types. Physical exercises such as jogging, Taijiquan, and basketball can be performed, but attention should be paid to the intensity of exercise, and it should not be too intense. Avoid disturbing the yang.
And don't get up too early for outdoor activities, it is better to wait for the sunrise.
In terms of diet, Bi Xiuxia suggested that the diet should reduce saltiness and increase bitterness to nourish the heart and qi, so that it can not only resist severe cold, but also store energy. For lotus root, etc., grains, fruits and vegetables that strengthen the spleen, protect the stomach, and nourish qi can also be used to regulate the spleen and stomach, nourish the internal organs, and prepare for the coming spring.
"Great Cold" is the last solar term in winter. Bi Xiuxia suggested that everyone should still conform to the characteristics of winter storage in their daily lives, so that they should go to bed early and get up late. ” Bi Xiuxia said that there is an old saying that “It’s a big cold and a big cold, and you need to protect yourself from the wind and cold.” In the big cold season, in addition to paying attention to protection from the cold, you must also protect yourself from the wind. Clothes should be changed with the temperature changes, and hands and feet are easy to freeze.
In addition to going to bed early and getting up late to prevent cold and wind, Bi Xiuxia said that it is best for everyone to develop a good habit of washing their feet before going to bed.
As the saying goes, "cold comes from the feet, cold comes from the legs", when a person's legs and feet are cold, the whole body is cold.
Soaking your feet in hot water before going to sleep can dilate blood vessels, speed up blood flow, improve skin and tissue nutrition on the feet, reduce muscle tension, and improve sleep quality. It is beneficial for preventing freezing feet and preventing diseases.
Especially those who love to read and write at night and sit for a long time until late at night, they should soak their feet in hot water before going to bed.
There is a saying that "warm the body first, warm the heart, warm the heart, then the body is warm", which means that when the mind is strong, the qi is smooth, the blood is smooth, and the limbs and bones are warm, it can resist the invasion of the harsh winter.
Therefore, Bi Xiuxia said that in the cold season, everyone should feel at ease and recuperate.
In particular, the elderly should pay attention to maintaining a comfortable and peaceful mind, so that the qi and blood in the body are in harmony, and do not disturb the yang qi stored in the body, so that "the righteous qi is stored in the body, and the evil cannot do it".
