Q: When is the cold dew in 2020? A: The cold dew in 2020 is the solar calendar time: 03:55:07 on October 8, 2020, and the lunar calendar date is Thursday, August 22, 2020.

In ancient times, dew was regarded as a sign that the weather turned cold. The solar term of the Mid-Autumn White Dew is "dew condenses white", and it is already "dew cold, it will condense into frost" when it is cold in season and autumn. At this time, the temperature in various places continued to drop. The average daily temperature in the basin is below 20℃. Even in the areas along the Yangtze River, it is difficult for the mercury column to rise above 30℃, while the minimum temperature can be reduced to below 10℃.

Except for a few valley lowlands, the five-day average temperature in the western Sichuan Plateau is generally lower than 10℃, which is winter according to the standard of four seasons climate division. A thousand miles of frost shop is very different from the autumn colors in the basin.

During the cold dew period, 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. Frequent Mao Mao rains in the morning and evening have affected the generation of "Sanqiu" and become disastrous weather in the basin.

The climatic characteristics associated with the rain in Mao Mao are: high humidity, more clouds, less sunshine and more cloudy days, and the number of foggy days has obviously increased since then. However, whether the autumn rain seriously affects the progress and quality of "Sanqiu" directly.

To this end, on the one hand, we should use the weather forecast to harvest and sow in sunny days; On the other hand, according to local conditions, we should take various effective farming measures such as deep ditch and high compartment to reduce wet damage and improve sowing quality. In the plateau area, before and after the cold dew is one of the most serious seasons of snow damage. Snow jams traffic and harms animal husbandry production, so we should pay attention to prevention.

Climate characteristics after cold dew, the temperature drops faster and drier: the rapid temperature drop is a feature of cold dew solar terms, and the weather becomes dry. At this time, the geese fly south and the chrysanthemums turn yellow. Compared with the "white dew" a month ago, the temperature is lower, the dew is more, and it is chilly.

The average temperature distribution is quite different: from June 5438 to 10, the average temperature distribution in China has obvious regional differences. The average temperature in most parts of South China is above 22℃, and it is even higher in Hainan, which is above 25℃, and it has not yet come out of summer. Jianghuai and Jiangnan are generally between 15℃ and 20℃, while southeast, north China and Huanghuai are between 8- 16℃. At this time, the average temperature in parts of the northwest and north-central northeast has reached below 8℃. The average temperature in some plateau areas of Qinghai Province is even lower than 0℃.

Cold air frequently goes south: after entering the "cold dew", the invasion frequency and intensity of cold air in the north will increase, and the rapid temperature drop is a major feature of the "cold dew" solar term. It is common for the temperature to drop by 8℃ to 10℃ after the autumn rain brought by a strong cold air.

Rainfall is scarce, and thunderstorms almost disappear: with the arrival of cold dew, most parts of China will turn cold, and the northeast and northwest regions have entered or will soon enter winter, with less rain. In addition to the perennial snow on the Qinghai-Tibet Plateau, it has generally begun to snow in the northeast and northern Xinjiang.

Cold dew keeps your feet warm. As the saying goes, "cold dew warms the feet." After the cold dew, the temperature gradually dropped. Therefore, the public should not often go into battle shirtless to prevent the cold from invading the body. At the same time, sandals in summer can basically be put away to prevent "cold". Citizens can soak their feet with hot water every night, which can dilate blood vessels, speed up blood flow, improve skin and tissue nutrition of feet and feet, reduce lower limb pain and relieve fatigue.

Since ancient times, the foot has been regarded as the second heart of the human body. According to the theory of keeping in good health, feet are farthest from people's hearts and bear the heaviest burden. Therefore, this place is most likely to lead to poor blood circulation, and the fat layer of the foot is very thin, with poor thermal insulation performance, which is easily stimulated by cold. It is found that there is a close nerve connection between foot and upper respiratory mucosa. Once the feet catch cold, it will cause the capillary contraction of the upper respiratory tract mucosa, and the ciliary movement will be weakened, which will lead to the decline of human resistance. Therefore, it is particularly important to keep your feet warm.

Add clothes at the right time In addition, after the cold dew, the weather is cold, and the elderly, children and citizens with weak constitution should pay attention to cold and warmth, and gradually add clothes. As the saying goes, "Spring covers autumn", and moderate cold in autumn is beneficial to improve the cold resistance of skin and nasal mucosa, but the elderly and people with various chronic diseases should pay attention to cold and warmth to prevent "freezing" from getting sick.

Don't change clothes too quickly when changing seasons. The thickness is best matched, mainly to keep warm. "Don't wear light clothes" is also an important point of cold dew health. Cold dew season, in daily life, should also be arranged reasonably. It is believed that when the temperature drops and the air is dry, the pathogenicity of cold virus increases. When the ambient temperature drops, the disease resistance of human upper respiratory tract will decrease. So in order to prevent colds in time, it is necessary to 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.

It's beginning of autumn season with alternating hot and cold. Autumn, autumn dryness is a troublesome thing. Health experts suggest that the best diet to deal with autumn dryness is: "salt water in the morning and honey soup at night." It is found that the skin is getting drier and drier, and many people think that they can replenish water by drinking more water. The fact is that drinking boiled water alone is easy to lose water. However, if you add a little salt to the boiling water, the situation will be very different. This method is the same as supplementing normal saline.

Drinking salt water during the day and honey water at night is not only a good way to replenish human body's water, but also a good diet for health preservation and anti-aging in autumn, and can also prevent constipation caused by autumn dryness. Modern medicine has proved that honey is effective for neurasthenia, hypertension, coronary arteriosclerosis and lung disease. Taking honey often in autumn can also moisten the lungs and nourish the heart. Therefore, when autumn comes, it is best to "drink light salt water in the morning and honey water at night" to keep healthy.

Early to bed and early to rise, after the cold dew, the days are short and the nights are long, and the "Yang" in nature begins to converge and precipitate. At this time, it is time for people to maintain yang, so people's living time should be adjusted accordingly. "Su Wen Si Qi Diao Ling" has "Autumn and March, go to bed early and get up early, and have fun with chickens." The argument is to tell people the truth of keeping fit in autumn. Experts say that going to bed early can conform to the convergence of yang, and getting up early can stretch lung qi, so we should "go to bed early and get up early" in autumn. In order to avoid thrombosis, we should follow the solar terms and take care of ourselves at different times to ensure our health.

Diseases such as gastrointestinal dysfunction and neurasthenia caused by physical weakness are prevented and treated by this method, and the effect is very good. Ginger-separated moxibustion is also a moxibustion method often used by modern people. Take a slice of ginger, cut it into thick slices, put a few eyes on it, put it on your navel, light the moxa cone, and do bird pecking moxibustion on the ginger (just like bird pecking), which feels warm and comfortable.
