Solar terms that are not cold in March and September

Because of the invasion of cold current, February 9 this year was extremely cold, so March 9 was not cold by comparison. According to the Central Meteorological Observatory, February 29th this year was the coldest since the 20th century, at 2 1. It has exceeded the lowest meteorological temperature in the last century. On the other hand, March 9, which has arrived, is not so cold due to the influence of cold air.

First, this year is abnormal.

Affected by the cold wave weather, the temperature in northern China has generally dropped by more than 8 degrees, and the area of up to 400,000 square kilometers has dropped by more than 12 degrees. The minimum temperature of more than 60 meteorological stations in Beijing, Shandong, Hebei, Shanxi and other provinces and cities exceeded the minimum temperature alarm value since the station was established. At present, although March 9 has arrived, the cold air activity is not as frequent as February 9. On the contrary, the temperature is rising in most parts of the country, and it will be much higher than the same period last year. However, the northeast is still dripping into ice, and netizens have said that they are freezing to death.

Second, the origin of Sanjiu.

Now many young people don't know what Sanjiu means. This is actually a proverb among the elderly. From the day of the winter solstice, it is 19 every nine days, and * * is 998 1 day, among which Sanjiu should be the coldest nine days in the whole year, after 8 1 day, spring blossoms, and 999 cows go everywhere. 99-99' s anti-cold pictures are generally popular in March 9th, but now they are basically gone. The content of the 99-99 cold-eliminating map is generally plum blossom, with a * * * and 8 1 petal. At the end of the day, when a petal is dyed and 8 1 flower is dyed, spring will come. In addition to 1999' s map of relieving cold, there is also a popular nine calligraphy and painting, which is generally a few proverbs, one * * * eighty-one paintings, and the proverbs of 1999 will cover it.

Three, three nine things that should be paid attention to.

The noteworthy place of Sanjiu is to keep warm. Winter in the north is no joke. When traveling outdoors, you must keep warm against the cold. It's wet and cold in the south, so we should pay attention to eating spicy food to prevent catching a cold. The elderly should pay more attention to the prevention and control of diseases in the March 9 weather. Once you catch a cold, it is easy to stimulate coronary artery contraction spasm in patients with coronary heart disease, resulting in insufficient blood supply. People with respiratory diseases should also pay attention to the fact that cold will lead to decreased metabolism and decreased lung function. Digestive system diseases are also in a high incidence period, and cold food is easy to cause chills. Osteoarthropathy is easy to recur in the season with large temperature difference between day and night, so we must pay attention to keep warm.

With the improvement of living standards, three to five days is not as hard as the elderly, but friends should not take it lightly. They should pay attention to protect themselves in this cold winter, and happy days should be enjoyed by our healthy bodies.
