Drinking cold water is a rare behavior in our eyes. Unless it is very hot in summer, if you drink a glass of ice water at this time, you can instantly cheer up and bring yourself a cool breath in the hot summer. But if you let us drink cold water in cold winter, then I believe many people will be unbearable, because winter is already very cold. If you drink cold water, your body temperature will drop, so. So what is the reason?
This is actually a cultural difference between China and the West. Although Japan has inherited a lot from our culture, they have also made great progress in the process of inheritance. The reason why Japan drinks cold water is entirely because of their natural environment, because Japan is a mountainous country, but it is also a country with many volcanoes. So in Japan, their water resources generally come from these high mountains in nature. After layers of filtration by nature, the water quality will be relatively better, and they have strictly disinfected the water. Therefore, tap water in Japan can be drunk directly by the public or on the street.
Under the habit of drinking like this for a long time, Japan gradually formed the habit of drinking cold water before meals. If they don't drink cold water, they may feel that there is a strange taste in the food, which will make them feel uncomfortable when eating. Therefore, drinking a glass of ice water before meals is not only a habit for them, but also a unique culture.
