Cold dew is the17th solar term in the twenty-four solar terms, and the "cold dew" solar term is a symbol of cold weather, indicating that it turns from cold to cold. "Twenty-four solar terms" said: "In September, the dew is cold and will condense." Cold dew means that the temperature is lower than that of the white dew, and the dew on the ground is colder and will soon condense into frost.

Cold dew does not show your feet, so keep your feet warm.

Professor Peng Kang, vice president of the Hospital of Integrated Traditional Chinese and Western Medicine of Southern Medical University, academic leader, chief physician of the Center for Disease Control and Prevention (Integrated Traditional Chinese and Western Medicine) and doctoral supervisor, said that Nanling and the vast areas north of it have entered autumn in the cold dew season, and the northeast and northwest regions have already entered or will soon enter winter. In ancient China, the cold dew was divided into three stages: "The first stage was the swan goose; Second, the sparrow enters the water and becomes a clam; Three chrysanthemums have yellow flowers. " It means that the geese in this solar term move southward in a word or herringbone queue; In the cold late autumn, all the birds disappeared. The ancients saw a large number of clams suddenly appearing on the seashore. The stripes and colors of shells were very similar to those of birds, and they thought they were birds. The third stage of "Chrysanthemum begins to blossom" means that the chrysanthemum has opened in a large area at this time.

When the cold dew comes, the autumn is stronger, the summer heat fades and people feel more relaxed and free. However, there is a folk proverb called "cold dew does not show your feet", which says that if you encounter cold dew, you should stop wearing sandals barefoot and pay attention to keeping your feet warm. Traditional medicine believes that "the disease starts from the cold and the cold starts from the foot." Professor Peng Kang explained that because the foot is the starting point of the three Yang meridians and kidney veins of the foot, if the foot is cold, cold pathogens will invade the human body and cause damage to organs such as liver, kidney and spleen. Now medical theory has also confirmed the importance of keeping feet warm for health. Feet are far away from the heart, with less blood supply, and the fat layer on the surface of feet is very thin, so feet are very sensitive to cold. It is worth noting that once the feet catch cold, it will also reflect and affect the normal physiological functions of the upper respiratory mucosa such as nose, pharynx and trachea, weaken the ability of these parts to resist pathogenic microorganisms, thus leading to the enhancement of pathogenic bacteria activity and making the human body more susceptible to various diseases.

It is also a good method to soak feet with traditional Chinese medicine in the cold dew season.

Professor Peng Kang suggested that in order to keep feet warm, besides "barefoot", it is also a good method to soak feet with Chinese medicine.
