Is it the big cold or the little cold?

Xiaohan is the twenty-third of the 24 solar terms of the year. During the small cold season, the sun apparently travels to 285 degrees of yellow longitude, which falls on January 5 or 6 of the Gregorian calendar. After a small cold, China's climate began to enter the coldest period of the year.

As the saying goes, air conditioning accumulates for a long time and is cold. At this time, the weather is cold, and Dana has not yet reached the extreme, so it is called Xiaohan. In fact, climate observation data show that the temperature of this solar term is the lowest, and the midwinter "Sanjiu" is basically in this solar term, so there is a saying that "a small cold is better than a big cold".

The two ancient folk proverbs "Little Cold, Big Cold and Frozen Together" and "Walking on the street, losing money" are two ancient folk proverbs that describe the coldness of this solar term. Due to the very low temperature, wheat, fruit trees, melons and vegetables, livestock and poultry are susceptible to freezing cold. Why is it called Xiaohan and not Dahan?

This is because the solar terms originated in the Yellow River Basin, and it is said in the "Seventy-two Candidate Explanations of the Lunar Order" that "the cold at the beginning of the month is still small......The moon and a half are bigger", that is, in the Yellow River Valley, the big cold was colder than the small cold at that time. And because Xiaohan is still in the last few days of the "Twenty-Nine", Xiaohan only enters the "Thirty-Nine" after a few days, and the Xiaohan in winter corresponds to the Xiaoxiao in summer, so it is called Xiaohan. Although there is no small cold, the "Forty-Nine" in the "Forty-Nine Night's Sleep" is also very cold, and the great cold in winter happens to correspond to the great heat in summer, so it becomes a great cold.

The phenological reflections of the three candidates in Xiaohan are: "one is Yanbei Township; The second magpie begins to nest; "Three migratory pheasants" in the migratory birds, geese migrate along the yin, at this time the yang energy has moved. Therefore, the geese began to migrate northward, but not yet to the northernmost part of our country, but only to leave the hottest place in the south; The second magpie feels the yang energy at this time and begins to build a nest; When the third weather came, the pheasant also felt the growth of yang energy and chirped.

The Xiaohan solar term is in the "39" cold day, which is the coldest time of the year. This is a good time for people to strengthen their physical exercise and improve their physical fitness. However, according to the individual's physical condition, we must not be blind, even if the person is in good health, we must pay attention to the way and method of exercise.

Great cold, Chinese characters have meanings.

The big cold is better than the small cold, because the small cold is in front of the big cold, the small cold is just starting to get cold, and the big cold is when it is very cold. There is another reason why big is greater than small . So the big cold.

Little cold.

According to China's meteorological data, Xiaohan is the lowest temperature solar term, and only a few years when the temperature of Dahan is lower than that of Xiaohan. As the saying goes, the cold is in the 39th, and the 39th day is in the small cold solar term. The little cold marks the beginning of the coldest day of the year.

Winter ninety-nine is counted from the day of the winter solstice, every nine days is a nine, counting one nine, counting two nine, until ninety-nine eighty-one days, this is a kind of folk solar term used to reflect the winter temperature change since ancient times. As soon as the winter solstice arrives, it will enter the often said cold days of counting nine, and the weather will be warm after counting ninety-nine.

Although several records of modern meteorological observations show that in most areas of China, the big cold is not as good as the small cold, but in some years and a few places along the coast, the minimum temperature of the whole year will still appear in the big cold solar term. In the cold season, the average temperature in most parts of southern China is mostly 6 to 8, which is nearly 1 higher than that of Xiaohan. "The small cold is the big cold, and the cold is a ball"The proverb shows that the Great Cold Solar Term is also a cold time of the year.

Today's society is a rapidly developing society, the rapid development of the economy is also driving the rapid development of science and technology, and at the same time there are a lot of answers to meteorological questions, that is, Xiaohan and Da Han, compared with Xiaohan is colder, because according to the observation data of modern meteorology, most years in many parts of the country are still Xiaohan, better, although she is called Xiaohan, but he is colder than Da Han.

There is a proverb that also profoundly expresses the evidence that the small cold is better than the big cold, and the proverb says that the small cold is better than the big cold, which is not uncommon. It has to be said that people's representation of cold is different, and in ancient times, human beings felt the temperature of the weather according to the thickness of the ice. But now we are using scientific data to measure the cold, that is, we know to measure the temperature of the cold, the cold is the coldest when the small cold is small, the ancients measured the cold according to the thickness of the ice, the ground freezes the hardest when the big cold is the hardest, so the ancients felt that the cold is the coldest.

Through this incident, we can also see that because the development of science and technology has helped us solve a lot of mysteries, the cold weather is indeed very cold, and we have all put on big cotton pants and big cotton jackets to spend this cold winter, I have to say that there are no such troubles in the north, whether it is a big cold or a small cold house, there is heating, so I will not feel very sad, which also benefits from the economic development of our country.

I have to say that now many people have the experience of eating watermelon in the heating room, but in the south of our country they are not so happy, although they do not have the experience of minus twenty or thirty degrees, but the rain and cold wind howling all day long is also very unbearable, this is not the south of the friends are also calling to give themselves heating, there have been many areas have also been warmed, it can also be seen that China's economic development has brought more convenience to people at the same time, we also hope that everyone can not be afraid of the cold, Like a ball of fire.

I think that Xiaohan will be colder, because in the pre-Qin period when the 24 solar terms first germinated and founded, and then in the Central Plains, it is possible that the big cold is indeed colder than the small cold.

It's even colder during the cold season

We all know that the winter solstice is preceded by the winter solstice, although the heat of the ground gets from the sun on the day of the winter solstice after the winter solstice, there is still some heat in the deep layer of the soil, which will be continuously dissipated, but after the winter solstice solar term, the heat in the deep soil continues to be lost, until the time of the small cold solar term is close to the lowest point, so even if the daytime time is constantly extending at this time, the light and heat absorbed from the sun every day have increased slightly, but in fact, the heat at this time is "beyond the means", Therefore, it becomes the coldest time of the year during the Xiaohan solar term. It's the same as when the hottest time of the day is not 12 noon, but 2 o'clock in the afternoon.

Xiaohan is colder, after the winter solstice, it enters the coldest "three nine days", Xiaohan is also in this period, and there is a saying that "small cold is better than big cold".

There is no one relatively accurate answer to this, because there is a big difference between the north and the south, the south thinks that the big cold is colder, and the north thinks that the small cold is colder. So it depends on the region where the individual is, I may be from the Northeast, and I think Xiaohan is colder.

I think it's a bit colder because it's windy, there's a lot of snowfall, and the roads are covered with snow, and then it feels like it's freezing.

I think the big cold is a bit colder, because the big cold is the coldest time of winter, and the big cold time is also the time when the temperature is the lowest in winter.

I think the cold will be a little colder. Because the great cold belongs to the 29th day, the 29th day is the coldest time in winter.

The big cold is better than the small cold.

Xiaohan is the coldest month of the year, "Seventy-two Candidate Explanations of the Lunar Order".

said: "Xiaohan, December Festival." At the beginning of the month, the cold is still small, so the clouds. Half a month is a big deal. "The first half of December is a small cold, and the second half of the month is a big cold, according to the ancients' interpretation of small cold and big cold, the big cold is better than the small cold.

There is no definite answer to this question, historical statistics show that the situation is different in different places and different years, generally speaking, the average minimum temperature of the northern Great Cold solar term is lower than the average minimum temperature of the Xiaohan solar term; The South is the opposite.

Climate experts believe that there are many factors that affect whether a place is big cold or light cold, and whether it is a small cold or a big cold in a certain year or a certain region needs to be analyzed in detail.

Moreover, the climate is changing, and statistics from recent decades can only reflect the situation in the recent period, and the climate in the recent period is not necessarily the same as the climate of 2,000 years ago.

Whether it is a small cold or a big cold is a question that needs to be analyzed on a case-by-case basis. The ancients set the small cold and the big cold in the 24 solar terms in order to indicate different degrees of coldness. In many cases, it is more cold than cold, but it is also necessary to distinguish regions, such as north and south.

In general, the big cold in the south is colder than the small cold. Because the cold wave is generally stronger when it is cold, the impact on the south is relatively greater.

The ancients set the small cold and the big cold in the 24 solar terms in order to indicate different degrees of coldness. "Giving Time to Test the Heavenly Time" quotes "Three Rites and Righteous Sect": The big cold is the middle, and the upper form is in the small cold, so it is called.

The reverse of the cold is called the great cold. Looking at the text, the big cold should be colder than the small cold. But in some places, there is also a saying that the small cold is better than the big cold, that is to say, the small cold is more cold than the big cold.

Because according to the cold.

Three. Nine, 3949 on the river to walk 3949 frozen dog said. Xiaohan has a total of 15 days, of which 12 days are in.

Three. In the middle of 9 and 49, it is inferred that the temperature is the lowest during the small cold period.

Both the small cold and the big cold belong to the solar terms of winter, and it is the process of the temperature changing. In our consciousness, the big cold should be better than the small cold, but this is not the case in nature, more often than not, the small cold is colder, and the specific area is different, just like the gap between the north and the south.

In the 66 years from 1951 to 2016, 27 years were spent in the year when the little stuffiness was colder and colder, and 19 years were in the year when the big cold was colder, and the two were equivalent to 20 years.

3.Indoor attention should be paid to open windows, ventilate, and have high messy liquid

In winter, the air pressure will be lower and the oxygen content in the air will be relatively reduced. In order to keep warm indoors, doors and windows are closed more strictly, and poor ventilation will occur. As a result, oxygen in the room is further reduced, often making people feel depressed and tight.

There are many people who like to sleep with their heads covered, especially in winter due to the low temperature, and some people like to bury their heads, faces, mouths, and noses in the quilt.

In the case of limited indoor air conditions, doing so can cause a lack of oxygen on its own. The harm of sleeping with the head covered is also that the ventilation in the quilt is poor, the air is dirty, and the human body cannot carry out normal gas exchange, so that there is less and less fresh oxygen in the quilt, and more and more carbon dioxide accumulates, which is easy to cause people to lack oxygen. In severe cases, it will cause nightmares and mental fear due to lack of oxygen, and it will suddenly wake up, and over time, it can also cause sequelae such as the weakening of the divine cavity meridian.
