After the "cold dew", the weather gradually cooled down, and there is a proverb that "the white dew does not show the body, and the cold dew does not show the feet". This is to warn people to pay attention to the weather changes, especially to keep warm, increase or decrease clothes in time to prevent the invasion of cold evil, especially not barefoot, in case of "cold self-sufficiency."

2. Eat more sweet food.

In the aspect of diet and health care, we should eat more sweet and light wet foods according to the individual's specific situation, which can not only replenish the spleen and stomach, but also moisten the lungs and intestines, and also prevent dry throat, such as sesame, glutinous rice and dairy products. Eat more fresh fruits, such as pears and persimmons. Vegetables include carrots, white gourd, beans, fungi, kelp and laver.

Middle-aged and elderly people and patients with chronic diseases should eat more red dates, lotus seeds, yams, ducks, fish, shrimps, beef and other foods. At the same time, we should pay attention not to eat or eat less spicy barbecue food, such as pepper, pepper, cinnamon, ginger, onion, wine and so on. Ginger, in particular, is easy to get angry after eating, which aggravates the harm of "autumn dryness" to human body.
