A recent survey found that the average human growth rate in China is lower than that in Japan and South Korea. Experts explained that besides genes, diet, physical activity and sleep can also influence height and growth.
The average height of males and females in South Korea is 174.92 centimeters and 162.34 centimeters respectively, ranking first among the three countries, according to a report done by Imperial College London. Among the three countries, China ranked second and Japan ranked third.
Data also showed that males in the other two countries grow faster than males in China. South Korea ranked third on the list and Japan fifth. Though Chinese people have been growing increasingly taller over the past century, their growth rate still lags behind that of other countries.
Lu Dajiang, a Shanghai-based expert on the physical condition of students, believes that there are three primary factors to consider: diet, physical activity and sleep.
Milk provided periodically during classes ensures that Japanese students consume a sufficient amount of calcium. Indeed, various ingredients in typical Japanese meals ensure that Japanese students receive all kinds of nutrients. What’s more, in both Japan and South Korea, students have a passion for sports. Each student has a favorite sport that he or she practices on a regular basis.
Experts recommended that China take note of its neighbors’ success in diet and exercise. Meanwhile, one more thing to pay attention to is how many hours of sleep students get. Students should go to bed before 9 p.m. and get 10 hours of sleep per night.
