The first is environmental problems. For example, most tap water in Europe and America can be drunk directly, and you can drink it directly by turning on the tap. Moreover, their drinking fountains have only two grades of ice and heat, and there is no room temperature. At present, the domestic environmental pollution is serious, the water quality is generally poor, and the purification level is relatively general. You can boil the water before drinking it.
The second is the difference between our diet and physical quality. Because European and American diets are pragmatic, such as steak, bacon, cheese, bread and so on, and they drink milk every day. Their food intake, protein and calories are generally higher than those in China. Therefore, their physical quality generally belongs to fire, that is, their yang is relatively strong. If they drink hot water again, it will make their bodies hotter, while ice water belongs to negative water, so cooler water can restore their body heat balance.
China is an ancient civilization with a long history, and the habit of drinking water with boiled water has existed since ancient times. Like our tea in China, porridge is a good example. And all three-year-olds in China know that warm water is good for health. Because of our living habits and physique, drinking hot water is of great benefit, which can promote our metabolism and help the body detoxify. Moreover, foreigners don't drink boiled water at all. Our health-preserving culture in China is also highly sought after abroad. Germany, for example, is a coffee kingdom, but half the people drink tea every day. This shows that we are all warm-blooded animals. Sometimes we like to drink cold water when we are warm, and sometimes we like to drink hot water to neutralize things when we are cold or eat too cold, so balance is the most important thing.
