"Little cold even big Lu, happy magpie to build a new nest." The "Chinese Astronomical Almanac" shows that at 11:23 Beijing time on January 5, the "Little Cold" festival ushered in, marking the coldest day of the year - "Counting Nine Cold Days" arrived.
Luo Shuwei, a historian and researcher at the Tianjin Academy of Social Sciences, introduced that every year around January 5 of the Gregorian calendar is "Xiao Han", which is the twenty-third of the twenty-four solar terms and the fifth solar term in winter. Cold accumulation for a long time and cold, "small cold" means that the weather is cold, but the cold is still small, has not yet reached the coldest season, and then after half a month, "then big", that is, into the "big cold" festival.
"When it is cold, it is two or three or nine, and the north wind roars when it is cold." In general years, "big cold" is colder than "small cold", but in meteorological records, there are also times when "small cold" is colder than "big cold", "small cold is better than big cold, common is not rare". In such a cold season, the rivers are frozen, the soil is frozen, and the cold air in the north continues to move south, and everything in the world is lonely.
Although the "little cold" marks the arrival of a harsh winter, the cold to the extreme is the time when it is about to warm up. The biological world, which is sensitive to nature, began to sprout: the winter sun was faint, the thin plums were the first; the geese thought of the north country, the magpies began to nest, and even the pheasants in the mountain forest began to chirp.
Traditional medicine believes that cold is yin and evil, and the coldest time is the most prevalent, so "small cold" is the best time to supplement, but it is necessary to target their own health and physique, and cannot be supplemented at will.
Luo Shuwei suggested that the average person only needs to pay attention to adding more warm foods to the daily diet, such as mutton, so as to prevent the invasion of the human body by the cold climate. Health care should conform to the trend of natural collection, so that the essence is cohesive to moisten the five internal organs. Due to the "blood in the cold then coagulation", the elderly and infirm people with cardiovascular and cerebrovascular diseases should pay special attention to daily cold protection and warmth. Young and middle-aged people should adhere to a regular life and appropriate physical exercise, "move in winter, do not make a big or small illness." Usually, we must maintain an optimistic and smooth mood, calm and worry, and spend a long cold winter happily. (Reporter Zhou Runjian)
