Modern medical research believes that "temperature and humidity" are closely related to people's health. For example, if "six qi" is understood from the perspective of "temperature and humidity" (this understanding may be superficial and incomplete), "cold fire" is related to temperature; "Dry and wet" is related to humidity; "Part" is related to temperature and humidity. Due to the cold climate and dry air in winter, the manifestations of dryness in winter are: nosebleeds, swollen gums, dry throat, dry nose, dry lips and dry skin. The pathogenic factors of dryness-evil have the following characteristics: ① Most of them enter through the nose and mouth, and the lung is the main part of the disease. ② It is easy to cause insufficient body fluid, so it often shows signs of dryness. ③ Easy to cremate.

In addition to drinking more water, you should also nourish and prevent dryness through "diet therapy".

From the perspective of traditional Chinese medicine, different colors of food have different shapes and effects. Most white foods have moisturizing effects and are suitable for winter consumption. When cooking, you can choose white radish, Chinese cabbage, water chestnut, white gourd, lily, tremella, lotus root, lotus seed, peanut and pear. Among them, Chinese cabbage and radish, two popular vegetables, have the best effect, which can be described as more economical tonics.
