Bone line generally refers to the epiphysis, whose closure generally prevents height growth. The growth of height depends on two major factors, one is the innate genetic factor, that is, the height of parents, and the other is the acquired factors, such as the acquired nutrition, exercise, sleep, and so on. Before epiphyseal closure, appropriate sports and exercise, strengthen the child’s diet and nutrition during the developmental period, and ensure adequate sleep can promote the growth of height. If the epiphysis is closed, it is basically impossible to grow taller. If the epiphysis is not completely closed, the child’s height is obviously inferior to that of his peers, there are still chances to remedy the situation, for example, to develop the habit of going to bed early and waking up early, regular rest and relaxation, eat more food with high protein content and rich in vitamins, and also participate in some outdoor activities, such as jumping rope, playing basketball, swimming, running, etc., which will help the growth of height. Before your child’s epiphysis closes, it is recommended to go to the growth and development department of a regular children’s hospital as soon as possible to have a checkup to clarify your child’s height development.
