"It's a little cold, frozen into a ball". At this time, northerners will "cat winter" that is, hiding at home and not going out.

Cats spend the winter at home, which generally means staying at home. "Cat" means "hide" in Northeast dialect. When used in this sense, the subject of "cat" is generally human.

Therefore, in winter, the bedroom should be properly dusted and ventilated to reduce and inhibit the reproduction of germs and viruses and prevent diseases. In addition, ultraviolet rays in the sun can resist and kill a variety of germs and viruses, and can effectively prevent meningitis, influenza, measles and other diseases. And sunbathing in winter can also prevent rickets in children and osteoporosis in the elderly.

Therefore, when the weather is good, people should go outdoors more, bask in the sun, breathe more fresh air and adapt to climate change.

Introduction of Great Cold and Slight Cold:

Slight cold: It is the 23rd solar term among the 24 solar terms in the lunar calendar and the fifth solar term in winter, marking the official start of the winter season. When the sun reaches the longitude of 285 (slight cold), it marks the arrival of the coldest day of the year in China.

Great cold: it is the last solar term of slight cold. It is the last of the 24 solar terms in the whole year. Every year around 65438+1October 20th in Gregorian calendar, when the sun reaches 300, it is a severe cold.

Ancient books record: slight cold, December Festival. The cold was still small at the beginning of the month, so it was cloudy. It will be big in half a month. Great cold is the middle, and the upper form is slight cold, so it is called great cold ... the inverse pole of cold, so it is called great cold.

Slight cold and severe cold are solar terms indicating temperature changes. In most parts of China, slight cold and severe cold are the coldest periods, so the folk proverb is: slight cold and severe cold become ice cubes. According to China's long-term meteorological records, there is no slight cold in the great cold solar terms in the northern region; But for most parts of the south, April and September are the coldest, so the big cold solar terms are colder than the small ones.
