cold dew is the fifth solar term in autumn. The temperature continues to decline. The daily average temperature in the South reaches about 20 degrees, and the autumn is getting stronger. However, many areas in the north have begun to fall below 10 degrees, and winter is about to enter. What month and day is the cold dew in 2020? Next, let the old yellow calendar take you to learn more about it.

Q: what month and day is the cold dew in 2020? A: the cold dew in 2020 is the time of the Gregorian calendar: 03:55:07, October 8, 2020, and the lunar calendar date: Thursday, August 22, 2002.and
cold dew introduction in ancient times, dew was regarded as the representation of the weather turning cold. The mid autumn White Dew solar term "dew condenses and turns white". By the time of cold dew in autumn, it is "dew gas is cold and will condense into frost". At this time, the temperature continued to drop everywhere. The daily average temperature in the basin is less than 20 ℃, even in the coastal areas of the Yangtze River, it is difficult for the mercury column to rise above 30 ℃, while the minimum temperature can fall below 10 ℃.and
except for a few Valley lowlands, the average temperature in five days is generally lower than 10 ℃, which is winter according to the standard of climatology. Thousands of miles of frost shop, thousands of miles of snow, which is very different from the autumn of the basin. Agricultural production during the cold dew period ofand
. During the cold dew period throughout the year, the rainfall in the basin is also decreasing day by day. The western part of the basin is mostly about 20 mm, and the eastern part is generally about 30 to 40 mm. Continuous rain is very frequent, day and night, and Ming Ming is falling, which affects the "three autumn" production and becomes a disastrous weather in the basin. The climatic characteristics ofand
accompanied by continuous rain are: high humidity, more clouds, less sunshine, more cloudy days, and fog days have increased significantly since then. However, whether autumn rain is serious or not directly affects the progress and quality of "three autumn".and
to this end, on the one hand, we should use weather forecast to harvest and sow on sunny days; On the other hand, we should also take various effective farming measures such as deep ditch and high compartment according to local conditions to reduce wet damage and improve sowing quality. In plateau areas, before and after cold dew is one of the most serious seasons of snow damage. Snow blocks traffic and endangers animal husbandry production, so we should pay attention to prevention.and
climate characteristics after cold dew: the temperature drops faster and drier: the temperature drops faster is a feature of cold dew solar terms, and the weather becomes drier. At this time, the wild geese fly south and the chrysanthemums turn yellow. Compared with the "White Dew" a month ago, the temperature is lower, there is more dew and a chill. The average temperature distribution ofand
varies greatly: in October, the regional difference of average temperature distribution in China is obvious. In South China, the average temperature is above 22 ℃ in most areas, and higher in Hainan, above 25 ℃, which has not gone out of summer. It is generally between 15 ℃ and 20 ℃ in Jianghuai and Jiangnan, and between 8 ℃ and 16 ℃ in the south of northeast, North China and Huanghuai. At this time, the average temperature in some parts of the northwest and the middle and north of the Northeast has reached below 8 ℃. The average temperature in some plateau areas of Qinghai Province is even below 0 ℃.and
cold air frequently go south: after entering the "cold dew", the invasion frequency and intensity of the cold air in the north will increase. A major feature of the "cold dew" solar term is that the temperature drops rapidly. After the autumn wind and rain brought by a strong cold air, it is common for the temperature to drop by 8 ℃ to 10 ℃.and
have few precipitation and thunderstorms almost disappear: with the arrival of cold dew, most parts of China will turn cool. The northeast and northwest regions have entered or are about to enter winter, with less rain. In addition to the Qinghai Tibet Plateau, where snow flies all year round, snow has generally begun to fall in the northeast and Northern Xinjiang.,

cold dew keep your feet warm. As the saying goes, "cold dew does not expose your feet." after the cold dew, the temperature gradually decreases, so citizens should not often expose themselves naked to prevent cool air from invading their bodies. At the same time, sandals in summer can be basically put away to prevent "cold from your feet". Citizens can soak their feet in hot water every night, which can expand the blood vessels and accelerate the blood flow of the feet, improve the nutrition of the skin and tissues of the feet, reduce the occurrence of lower limb pain and alleviate fatigue.and
feet have been said to be the second heart of the human body since ancient times. From the perspective of health preservation theory, the foot is farthest from the human heart and the burden is the heaviest. Therefore, this place is most likely to lead to poor blood circulation. In addition, the fat layer of the foot is very thin and the thermal insulation performance is poor, which is easy to be affected by cold stimulation. The study found that there is a close neural connection between the foot and the upper respiratory tract mucosa. Once the foot catches a cold, it will cause the upper respiratory tract mucosa capillaries to contract and the ciliary movement to weaken, resulting in the decline of human resistance. Therefore, foot warmth is particularly important. In addition, after the cold dew, the weather is cold, the elderly, children and citizens with weak physique should pay attention to cold prevention and warmth, and gradually add clothes. As the saying goes, "spring covers autumn". Moderate cold in autumn is conducive to improving the cold resistance of skin and nasal mucosa. However, the elderly and people with various chronic diseases should pay attention to cold prevention and warmth to prevent "freezing" from getting sick.and
don't change clothes too quickly during the season. It's best to match the thickness to keep warm. "Don't wear single clothes" is also an important point of cold dew health preservation. In cold dew season, we should make reasonable arrangements in our daily life. Research shows that when the temperature drops and the air is dry, the pathogenic ability of cold virus increases. When the ambient temperature drops, the disease resistance of human upper respiratory tract will decline. Therefore, in order to prevent colds in time, change clothes in time.
at the same time, first-aid drugs should be prepared at any time to prevent sudden diseases such as asthma, stroke and myocardial infarction caused by sudden drop in temperature.
towards salt and late honey cold dew is the beginning of the alternating autumn of heat and cold. In autumn, autumn dryness is a troublesome thing. Health experts suggest that the best diet for dealing with autumn dryness is: "salt water in the morning and honey soup in the evening". Found that the skin is getting dry, many people think that as long as you drink more water, you can replenish water. The truth is that just drinking boiled water is easy to lose water. However, if a little salt is added to boiled water, the situation is very different. This method is the same as supplementing normal saline https://www.dailyq-a.com/Culture/28841.html
