As early as thousands of years ago, Huangdi Neijing, an ancient Chinese medicine book, had the principle of "nourishing yang in spring and summer and nourishing yin in autumn and winter". So, what exactly is yang? Chinese medicine believes that yang is the motive force of human body's material metabolism and physiological function, and people's normal life activities need yang support. Mao Dan, Department of Integrated Traditional Chinese and Western Medicine, Xiangya Second Hospital, said that in summer, when the human body's yang is at its peak, it can be cultivated and supplemented more vigorously, which can resist the invasion of diseases. However, because the summer heat is unbearable, many people like to drink cold drinks and eat cold food. In fact, this may damage the spleen and stomach and consume yang. Therefore, from the point of view of health, we should eat less cold drinks and cold melons and fruits in summer, and avoid cold water when drinking water. It is better to drink warm water, and we can also eat some warm foods, such as red dates, medlar and angelica. At the same time, because of the high temperature in summer, you can eat some foods to relieve summer heat, such as mung bean soup and lotus leaf soup. And because the weather is hot and you sweat a lot, you should replenish water in time.
Mao Dan reminded: During the summer solstice, you can go outdoors more, which can regulate qi and blood and maintain yang, but you should avoid exposure to the hot sun at noon, and choose to do activities in the early morning or evening when it is relatively cool. Usually, we should pay attention to the adjustment of the living environment, and there needs to be a transition period when we come out of the air-conditioned room, so that the temperature in the body can adapt to it, so as to avoid physical discomfort, even colds, air-conditioning diseases, etc. caused by rapid switching from high temperature to cold environment.
