Factors affecting a child’s height mainly include genetics, nutrition, sleep and exercise, etc. The details are analyzed as follows: 1. Heredity: In general, if the height of the mother and father is higher, then the child’s chances of growing taller are greater, and vice versa. 2. Nutrition: Children’s height development cannot be separated from the support of nutrients. Eating more food rich in protein and calcium is conducive to promoting the absorption of bones, which in turn promotes the growth and development of children. So it is recommended that children should eat more milk, eggs, shrimp and pork, beef and other foods. 3. Sleep: Growth hormone, which promotes height growth, is mainly secreted at night, so sleep is also crucial for children’s height development. 4. Exercise: Bouncing sports, such as basketball, high jump, long jump and so on. Before the epiphysis does not close, through jumping sports can help children grow taller, and after the epiphysis closes, it is traditionally believed that it will not grow taller. There may also be other factors affecting a child’s height, such as disease, etc. It is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy.
