What should we pay attention to in the climate characteristics of severe cold solar terms?

Cold dew is one of the twenty-four solar terms and the fourth solar term in autumn. The temperature drops gradually in autumn, so what is the solar term between Hanlu and beginning of winter? What are the weather characteristics of cold dew? Next, let's take a look at this issue of almanac!

What is the solar term between Hanlu and beginning of winter? The first frost, the first frost, is the last solar term in autumn. At this time, the weather is getting colder, autumn dryness is obvious, and dryness is easy to hurt body fluids. Pay attention to keep warm in the first frost, then prevent autumn dryness, and the amount of exercise can be increased appropriately. Preventing autumn dryness, autumn depression and cold protection are the key points of health care during the first frost. Autumn dryness is characterized by dry mouth, dry lips, dry throat, constipation and dry skin. In the first frost season, the temperature may suddenly drop, and people with chronic diseases, poor physique and weak resistance are likely to get worse or have a cold and fever. In addition, the stimulation of cold air will cause the contraction of human blood vessels and the sudden increase of blood pressure, thus inducing various cardiovascular diseases. The key to prevent the above diseases is to keep warm.

In terms of diet recuperation, this solar term should be supplemented. Pay attention to the spleen and stomach and regulate the liver and kidney. You can eat more foods that strengthen the spleen, nourish yin and moisten dryness. Sesame, tremella, green vegetables, apples, bananas, radishes, chestnuts, autumn pears, lilies, honey, yam, milk cabbage, beef, chicken and loach are all good. Don't put too much salt in your food. If you put too much salt in your food, it will increase your blood volume and be a burden to your blood vessels. And eating too much salt will lead to water shortage in the body. If you stay too long, your body will swell. There is an old saying that "the first frost is not as good as winter", so autumn is not as good as winter.

What are the weather characteristics of cold dew? Literally, the "cold" of cold dew is cold, and "dew" refers to the phenomenon that water vapor condenses into dew near the ground. But from the meteorological point of view, the solar terms of cold dew are the same as those of white dew and first frost, and the significance of its heat change is more obvious than that of humidity change. It should be said that it more embodies a process of temperature change and seasonal change. On a cold morning, you can see the crystal dew on the leaves of plants, but the dew is already very cold. Some friends in the south may ask, why is there no dew in the morning in the south? There is a simple reason. Twenty-four solar terms come from the Yellow River Basin. At this time, the temperature in southern Jiangnan is still high. Although it is only 15 days from the cold dew to the first frost of the solar term, it is the time when the temperature drops rapidly in a year. It is common that the average daily temperature drops by 8 or 10 after a cold air. Therefore, this season is the turning point of climate change in many parts of China.
