The causes of short stature in children and adolescents are very complex, ranging from organic to psychological factors, and from acquired to congenital genetic influences, so it is very important to go to the hospital to have your child diagnosed by a specialist as having short stature or normal stature, and to treat different causes. For children with normal short stature or children with organic diseases that require treatment, in addition to proper nutrition and adequate sleep, proper physical activity plays an important role in height growth. Under the premise of ensuring adequate nutrition, exercise is the most effective way to promote physical development and enhance physical fitness.

Exercise by itself does not increase genetically predetermined height, but exercise can promote the maximization of genetic potential. In addition, exercise can also enhance the body’s immune function and improve the resistance to foreign germs. Exercise is accompanied by sunbathing and air bathing to enhance the body’s ability to adapt to the surrounding environment.
