Whether or not a 16-year-old boy or girl can grow taller is mainly based on whether or not the epiphyses are closed, if the epiphyses are not closed, it is still possible to grow taller, if the epiphyses are closed, physiologically it is very difficult to grow taller. The growth of the human body is mainly accompanied by bone growth and development, only when the bone development stops, the height will stop growing. Every child’s height development is different, some children develop earlier, the basic development is completed at the age of 16, at this time the epiphysis will be completely closed. They will not grow any taller at this time. If the child’s development is normal, the epiphysis may not be completely closed at the age of 16, still in the process of development, at this time will grow taller. However, height can be affected by many factors, such as genetics, diet, exercise, sleep and so on, and if these factors are affected during growth and development, it will also lead to changes in height. It is recommended that adolescents should ensure adequate nutrition during growth and development, consume more protein and vitamin-rich foods, and ensure adequate sleep, which will help their height increase.
