After the light snow solar term, cold wave and strong cold air activities become more frequent. Gao Hui, a doctor of traditional Chinese medicine at Beijing Gulou Hospital of Traditional Chinese Medicine, reminded the public that the diet should be warm and moist at this time to avoid hot and cold. Gao Hui said that better heating and warm-keeping measures in northern winter will lead to "internal fire" in human body. Therefore, it is not advisable to eat hot and dry food after the light snow solar terms, so as not to breed excessive internal heat. The best ratio of meat to vegetables is 1: 5. You can eat more moist foods, such as white radish, Chinese cabbage, spinach, black fungus, sugar cane, tofu, yam and so on. At the same time, you should also drink plenty of water, moisturize body fluids and relieve discomfort such as dry mouth, dry throat, constipation and dry skin in winter. Honey water can moisten dryness and detoxify, white radish water can clear away heat and induce diuresis, and pear water can moisten lung and relieve cough.

Gao Hui said that Chinese medicine believes that kidney qi is abundant in winter, but salty enters the kidney. Therefore, after the light snow solar terms, the diet should be salty and bitter. He advised people to eat less salty food, such as crabs, animal blood, cuttlefish, clams and highland barley. Eat more bitter food, such as lettuce, celery, bamboo shoots, mutton, ginkgo, medlar, animal liver, etc.

After the light snow festival, the weather is often cold and gloomy, and people's mood is easily affected by it. Gao Hui suggested that everyone might as well eat some pleasant food. Bananas are rich in tryptamine and vitamin B6, which can cheer up the spirit and increase confidence; Milk can relieve tension and anxiety. Nuts such as walnuts, peanuts and almonds are rich in trace elements such as selenium, zinc and copper, which can improve mood. Communicating with friends, enjoying flowers and listening to music together can also increase the fun in life.
