Look at China. With a history of 5,000 years, how many predatory invasions have taken place abroad? Based on the peace and environment of mankind, they gradually formed various ideas of governing the country and ensuring the country, including the cultural concept of governing the world with "harmony", including food, clothing, housing and transportation. Everyone has their own unique TCM regimen, including drinking boiled water and tea culture, which is unique to China! This basic way of keeping in good health, this way of drinking boiled water, has formed a habit, a culture of its own, which is deeply rooted in people's hearts and passed down from generation to generation! China drinks boiled water, a kind of tea culture, a way of governing the country and keeping the country safe, a way of doing business, a way of keeping in good health in traditional Chinese medicine and so on!
Therefore, the formation of the simplest human habits, including the formation of a national custom, is behind the historical and cultural connotation of their origin. Looking at the essence through the phenomenon, we can analyze and infer the historical evolution of a nation from barbarism to civilization.
Americans like to drink cold water, while China people like to drink hot water. One of the main reasons is that their eating habits are very different. American food is mainly high-calorie food such as meat. Eating high-calorie food for a long time makes Americans feel hot, so drinking ice water can eliminate dryness and reduce heat. Over time, drinking ice water has become a habit. Second, the filtration and disinfection of the tap water system in the United States is very strict, and the tap water entering the home has reached the standard of direct drinking, so Americans are also used to directly connecting cold water with tap water.
Not only Americans, Europeans, especially people in northern Europe, people in Norway, Sweden, Denmark and other countries have the habit of drinking cold water, even ice water, even in winter. However, people in China usually drink cold water in summer, and in cold weather, especially in winter, they are used to drinking hot water and hot tea. This difference is obvious. My brother works in Jordan Company in Norway. He often travels abroad, especially in Europe. He also formed this habit. He also thinks that drinking cold water is good, and the cooler the better. This is somewhat puzzling. No matter from the theory of traditional Chinese and western medicine, you should drink hot water in winter.
The central nervous system of human body has heat-producing center and heat-dissipating center. The heating center works in cold days and the cooling center works in hot days, so the human body can keep a constant temperature of 37 degrees. If you do the opposite, drinking cold water desperately in cold weather will have a negative stimulating effect on the human body, especially the stomach. From the perspective of Chinese medicine, this problem is even more so. Chinese medicine pays attention to the balance between yin and yang, cold and heat, and eating hot food needs to be combined with cold food to achieve a comprehensive balance.
What's more, in cold areas and weather, more heat is needed to supplement. Russians often drink vodka just to drive away the cold and increase calories. People in North China, such as Northeast China and Inner Mongolia, have the habit of drinking to drive away the cold. Although southerners in China don't have this habit, the habit of cooking soup and nourishing the stomach in winter is more obvious. In a word, China people still follow the habit of eating warm food to nourish their stomachs in winter and eating cool food to clear away heat and detoxify in summer.
