I believe many people have discovered that people around them like to invite people to drink hot water when they have nothing to do, as if hot water can cure all diseases, while foreigners often drink iced drinks. People in China sometimes feel uncomfortable after taking a cold drink, so they can't help asking: Why do foreigners feel uncomfortable after taking a cold drink?
This is actually closely related to the different constitutions of foreigners and China people. Foreigners also drink iced drinks as usual in winter, because they usually eat a lot of high-calorie foods, such as French fries and chicken legs, and their eating habits are different, so their physique is different.
Besides, the living habits of foreigners are quite different from those of China. They like drinking very much in their daily life, and they like to match beef. When eating bread, they like to spread butter on it. These foods are high in energy. In daily life, foreigners are used to eating hot food, which leads to their hot constitution, so drinking ice drinks at ordinary times is not too harmful to their health.
In fact, foreigners also drink hot water, but it is different from the way people in China drink hot water. They are used to drinking coffee, and coffee is also made with hot water, which is equivalent to drinking hot water. Foreigners are just used to turning hot water into drinks. For example, English tea and soup before eating western food are considered as hot water. In the life of foreigners, there are also many hot drinks, but China people don't notice them.
