"Drink more hot water", the "wisdom" of China's rule over all diseases, has been a habit as early as 20,000 years ago. Professor Wu Xiaohong from Peking University Institute of Archaeology and Culture and his colleagues published an article entitled "20,000-year-old Pottery at Xianrendong Site in China" in Science magazine, and found that the pottery left by the ancestors of China was 20,000 years ago. Moreover, some of these unearthed pottery have burnt marks, which proves that they are used for cooking.

In addition, prehistoric pottery unearthed in Shandong also found traces of water. This proves that ancient China people already knew how to boil water for drinking.

People in China drink boiled water, and the earliest writing is recorded in Huangdi Neijing: "Timely Treatment Decoction", at least 2000 years ago. There was a habit of drinking tea with boiling water in Han dynasty, but in ancient times, drinking hot water meant consuming firewood, so most of them were only enjoyed by nobles.

Foreigners drink cold water all the year round. Why can't people in China live without hot water? Only by understanding the reasons can we know the gap.

Then why don't western countries drink hot water? On the one hand, in ancient Greek and ancient Egyptian pottery, no water-boiling vessels similar to those of China were found; Secondly, it is also related to eating habits. The diet of western countries is mainly beef and mutton, supplemented by cheese and butter, which is high in calories. Zhu Xinyi, deputy director of the Department of Traditional Chinese Medicine of Zhong Da Hospital affiliated to Southeast University, said that from the perspective of Chinese medicine, such a diet would lead to "excessive internal heat". When the fire is flourishing, the sun is flourishing, and it needs "yin water" to balance it. This is why many people want a glass of ice water to "relieve fatigue" after eating spicy and exciting food.

In addition, due to historical reasons, western countries attach great importance to water problems, and until today, the water quality in the west meets the highest standards in the world.

Second, many problems can indeed be alleviated by hot water.

"Drink more hot water" is a magic weapon of China health culture. For China people, drinking cold drinks is easy to hurt their stomachs. Drinking cold drinks often can easily cause dysmenorrhea in women and affect children's development. Jiang Liangduo, an old Chinese doctor at Dongzhimen Hospital of Beijing University of Chinese Medicine, told us that people in China are more suitable for drinking boiled water, and drinking warm water often has the following benefits to the body:

1. Accelerate metabolism: Under the warm action, human hormones can promote secretion and improve metabolic capacity, thus eliminating metabolites in the body more quickly.

Foreigners drink cold water all the year round. Why can't people in China live without hot water? Only by understanding the reasons can we know the gap.

2. Enhance respiratory function: Drinking boiled water can relieve the tension of respiratory mucosa, promote expectoration and relieve colds to some extent.

3. Reduce the onset of diseases: Drinking warm water regularly can promote blood circulation in the body, which is conducive to refreshing the mind, enhancing immunity and preventing diseases.
