1: In fact, many things want to trace back to the source, but they can't really figure out where they came from and when they came. One of them is why people in China like to drink hot water. Perhaps it is because doctors in the past gave such advice to people who are weak, and it was adopted by many people for the sake of good health; Or maybe China is the hometown of tea, so drinking tea and hot water has become a habit; Or because of the water quality, everyone thinks that it is more hygienic only when it is boiled, so everyone likes to drink hot water. In short, most of them still come from habits!

2. The tap water in China is clearly marked as not drinkable directly, and even there are some pebbles after the faucet leaks at home. In this case, water can only be heated before drinking. Coupled with the weak gastrointestinal function of modern people, drinking cold water will make the stomach more uncomfortable. So one of the standard thermos cups for middle-aged people is particularly popular.

But frankly, I have drunk iced drinking water abroad, and it is on an empty stomach in the morning. Reluctantly, there is nothing I can do. I was so thirsty that I drank some. However, to my surprise, there is no problem. You know, in China, my sensitive stomach often hurts. It can be seen that the water in some foreign countries is indeed much more sanitary than that in China.

3. Take the female physiological period as an example. At a special stage, drinking hot water will warm the abdomen and make people's spirits much better. I used to believe that I tried to drink cold water during my physiological period. As a result, the amount suddenly increased and the natural person was uncomfortable. One of my junior high school classmates likes eating ice very much. In the hot summer, the sorbet keeps coming, and as a result, the holiday is almost half a month. These facts also make people believe that drinking hot water will really make the body more comfortable.
