We have guests at home, and pouring a cup of hot water reflects the etiquette of family hospitality. If you can serve a cup of hot tea, it will be a courtesy to distinguished guests! Therefore, thousands of years of cultural accumulation have formed a drinking culture of "warm water and hot tea"!
We also often use "drink more hot water" to comfort our little sister who is menstruating, friends who have a cold, close relatives with gastrointestinal discomfort, or other various physical problems. We all want them to drink more "hot water", which has become the most sincere expression of caring for relatives and friends!
However, our recognized way of caring is incomprehensible in neighboring Japan, where we are only separated by a strip of water. They treat themselves and their guests with cold water with ice. Even the best Japanese convenience stores sell all kinds of water and drinks without room temperature, almost all of which are cold. Even children bring warm or cold water. Are you worried that their stomachs can't stand this way of drinking "ice water" all the year round? Are you worried about their spleen and stomach catching cold? Can girls drink ice water when they have their period? The answer to these questions: of course!
China girls don't say that they can't drink cold water during menstruation, let alone drink ice water. Even washing dishes and washing clothes with cold water will be temporarily suspended! Japanese adults and children drink water with ice cubes all the year round, but according to the statistics of life expectancy of the world population, the life expectancy of Japanese people ranks first. It seems that drinking ice water is not as bad as we thought!
Why do Japanese people drink "ice water" all the year round, but the life expectancy is the highest in the world, but we can't?
Japanese drink ice water for a reason. Let's see:
Cultural differences, perhaps in Japanese, water itself refers to cold water, while hot water is called soup, and "ice water" is called cold. Therefore, drinking water directly refers to ice water, while soup is used for making tea or coffee, washing dishes, bathing and other purposes. In their subconscious, they can't imagine how hot water can be drunk directly without anything. How tasteless is it? Once this culture is accumulated, it makes them feel that drinking ice water is better!
Infrastructure differences. Domestic water in Japan is filtered direct drinking water, which can be directly drunk, while our domestic water is tap water, which has not been strictly filtered and can not meet the standard of direct drinking, which also urges us to get used to drinking boiled hot water.
In Japan, even if you drink water directly, the treated water will inevitably have some "odor", so adding ice can eliminate the odor and taste better!
In addition, because it is direct drinking water, it is too casual and rude for guests to come home and receive water directly. With ice, it reflects the host's mind. Moreover, when the ice-making technology was underdeveloped a few years ago, ice water was used to greet guests to show respect, so it was slowly handed down.
Differences in eating habits. Japanese people are used to cold food, three meals a day, and the arrangement is probably cold food-hot food-cold food (simple family meal). If dinner is a formal dinner, it may be hot food. Even hot food contains many cold foods, such as fruits, vegetable salads or desserts. Other cold foods, such as vegetables, sashimi, iced milk and iced drinks, are normal!
These are probably the reasons why Japanese people always take drinking "ice water" for granted, just as it is normal for us to accept drinking hot water, so there is no need to be too skeptical.
Then why did the Japanese live so long? Khufu simple analysis with you:
Some people worry that if the Japanese eat too much cold food, it will lead to too much cold and dampness in the body. Your worry is unnecessary!
Hot spring facilities in Japan are particularly developed. People can not only go to special clubs to soak in hot springs, but also have hot spring facilities in some families. The frequency of soaking in hot springs is very high, which can better eliminate cold and dampness. Soaking in hot springs can dredge the meridians of the whole body, promote blood circulation and help prolong life!
In addition, as mentioned above, Japanese people like to eat cold food, so they keep the original nutrition of food to the greatest extent, and many beneficial ingredients are not destroyed. Compared with our China people's eating habits of high temperature, high oil and high calorie, it is more conducive to health, and a light diet is worth learning!
Japanese people can better control the amount of food they eat per meal. They eat very little in every dish, most of them are five or seven full, and they will not eat too full or too full, so they will not increase the burden on various organs. Relevant experiments show that the food intake will be reduced by 20%-30%, and the life expectancy will be prolonged by about 20 years, which may also be an important reason for promoting the longevity of Japanese people.
Japanese people pay attention to the combination of meat and vegetables, balanced nutrition, and there is another unnoticed place, that is, eating slowly, chewing slowly to better absorb food nutrition, will not lead to eating too much, and will undoubtedly contribute to longevity!
Japan has the highest per capita fish consumption. Compared with other red meats, fish meat contains more nutrients, and fish meat contains more high-quality protein and beneficial fatty acids. Relevant experiments show that the mortality rate of people who eat fish regularly can be reduced by about 27%.
These are roughly the main reasons for the average life expectancy of Japanese people. Of course, there are many factors that affect life expectancy, which are not unrelated to Japan's developed economic level and superior medical conditions!
Writing this article is not about worshipping foreign things, but about popular science. With the opening of culture, we should accept the cultures of different countries with an inclusive attitude. There is no good or bad culture. We are used to drinking warm water, but we also understand that Japanese drink ice water in winter. In fact, it is not only Japanese, but also many Europeans and Americans have the habit of drinking ice water all the year round!
Just as we don't have to worry about cows eating grass and wolves eating meat all day, we don't have to worry about fatty liver. Therefore, there are still differences in regions, cultures and habits about what water to drink, and ice water is unacceptable. So take a thermos cup and drink our warm water for health, but remind us that the temperature of hot water should not be too high, not more than 60 degrees, otherwise it will really hurt the digestive tract mucosa!
