So the Millennium actually indicates that the weather is getting cold. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. The temperature difference between day and night can reach more than ten degrees.
Yang Qi reached its peak in the summer solstice, and these two extremes must be reversed, and Yin Qi also rose at this time. When it comes to the White Dew, the yin gradually increases, and the morning dew gradually thickens and condenses into a layer of white water drops, so it is called the White Dew.
Extended data:
I. Meteorological characteristics
After plants began to have dew entering the Bailu solar term, summer monsoon was gradually replaced by winter wind, cold air turned to attack, and warm air gradually retreated. Cold air going south in batches will often bring a certain range of cooling. People like to use the proverb "it's cold in the autumn night in the white dew" to describe the situation that the temperature drops rapidly.
At this time, the precipitation in northern China is obviously reduced, and the autumn is crisp and dry. During this period, the first autumn rain in the middle and lower reaches of the Yangtze River can often alleviate the previous water shortage. However, if the cold air meets a typhoon, or the cold and warm air are evenly matched, the two sides are in a dilemma, and heavy rain or low temperature and continuous rain are not good for the growth of autumn crops.
Continuous rainy weather often occurs in the eastern part of Southwest China, South China and West China. There may be heavy rain caused by tropical weather system (typhoon) in the southeast coast, especially in the south China coast.
In addition, autumn drought, forest fire and first frost may also occur in some areas at this time. If the summer droughts in the middle and lower reaches of the Yangtze River, West China and South China are not nourished by autumn rain, summer and autumn droughts may all form.
There is a proverb that says, "There is no drought in spring, and the drought in autumn is halved. Building houses in spring drought and breaking grain in autumn drought. " In some northern areas, such as Shaanxi, Shanxi, Gansu, North China and other places in the northwest, autumn precipitation is inherently less. If severe autumn drought occurs, it will not only affect the harvest of autumn crops, but also delay the sowing and emergence growth of autumn sowing crops and affect the harvest next year.
In addition, with the autumn drought, especially the dry air and the increasing wind in mountainous forest areas, the forest fire risk in autumn began to enter a period of high incidence.
Second, the weather precautions
1, add clothes in time in the morning and evening.
There is a saying in Chinese medicine that "the Millennium is divided into autumn nights, and it is cold all night", which means that after the solar term of the Millennium, you can no longer go shirtless when you wear clothes.
In addition, the weather is changeable after the Millennium, especially the large temperature difference between morning and evening, which is easy to induce colds or lead to the recurrence of old diseases. If you are gluttonous and afraid of cold at this time, it is easier to make the spleen and stomach function abnormal and damage the yang of the spleen and stomach, especially those with spleen and stomach deficiency and cold should avoid eating.
2, pay attention to nutrition, moistening the lungs and moistening dryness.
Millennium is the solar term with the largest temperature difference between day and night throughout the year. After the Millennium, the temperature began to drop, the weather turned cold and the water vapor condensation on the ground began to increase. After the Millennium, people are prone to dry mouth, dry lips, dry throat, dry skin and other symptoms, which is a typical "autumn dryness."
The diet in the Millennium season should be based on invigorating the spleen and moistening dryness, and should eat things that are flat, sweet and warm, and should eat nutritious and digestible food. We should not eat too full, so as not to increase the burden on our stomach and lead to gastrointestinal diseases.
Don't be greedy when sleeping at night.
The Millennium is a solar term, indicating that the weather is getting cold. Although the temperature can still reach more than 30 degrees during the day, it will still be cold at night, and the temperature difference between day and night is large. If it rains, the temperature will drop more obviously. Therefore, we should pay attention to adding clothes and quilts in the morning and evening, and don't be topless and greedy when sleeping. The so-called "don't show your body in the white dew, remind you in the morning and evening" just illustrates this truth.
