Why do only China people like to take a nap, and foreigners don't have this habit? Maybe you'll understand after reading it.
Dietary difference
Our country is based on traditional diet. Compared with foreign countries, there will definitely be differences in kind. People in China usually live on rice and white flour, which will cause our blood sugar to rise obviously. Westerners usually like to eat meat and some nutritious meals, so they won't feel sleepy in the afternoon and there is no need to sleep.
There are cultural differences.
People in China usually have the concept of keeping in good health. People usually take a nap at noon in order to adjust their bodies and achieve a balance between yin and yang. In order to keep healthy, they can also make themselves energetic in the afternoon. But the western point of view is that people who take a nap are usually wasting their time, and they will do so for useless people or people with physical defects and pathological conditions.
Don't sleep at night
You know, people in China usually like to go to bed early and get up early. For foreigners, the working hours are very different. They usually go to work after nine o'clock and get off work after seven o'clock in the afternoon. And the lunch break is usually short, and western countries will also have some coffee to improve themselves. So the coverage of the brain is different, so they will form the habit of drinking afternoon tea.
No matter in school or company, there is basically a system of taking a nap, so everyone has developed such a biological clock. In western countries, their lunch break is very short, usually only enough for lunch, so there is no extra time for a nap. But now, because of our fast pace of work, many first-tier cities have begun to take a nap.
