What is the normal height for a 14 year old girl?

There are giants and dwarfs in the world. But being too tall or too short is abnormal, and both are caused by illness. There is a normal height range for each period of life. During adolescence, a person's height usually increases significantly, while in old age, the height may decrease due to the weakening of the bones and the inability to bear the weight of the body. Today I will talk about the normal height of a 14-year-old girl.

There are two peak periods in the process of human growth. One is from birth to 10 years old, with a fast growth rate of 25 cm per year. The second year grows 10-12 cm, the third year grows 8-9 cm, and from the fourth year to 10 years old, it grows 5-7 cm per year. The second period is puberty, during which children can grow 10 cm per year, and the growth rate slows down after the age of 20.

The height of the body is determined by the bones. There are a total of 206 bones in the body that play a major role in the growth of height, mainly the vertebrae of the spine and the bones of the lower limbs. Among them, the length of the lower limb bones plays a decisive role. Before the age of 7, the bones of the upper limbs and lower limbs are the same. At the age of 7-8, the growth of the lower limb bones accelerates and soon surpasses the upper limb bones. During puberty, the lower limb bones grow more rapidly and the height also increases significantly. This period is a critical period for the height of the body and is a decisive factor. A 14-year-old girl is generally in puberty and her height can reach about 158cm.

The lower limbs stop growing with the end of puberty. The growth of the spine will continue until adolescence, when it stops. A person's height is relatively equal in childhood, but during puberty, the lower body is obviously longer than the upper body. During young adulthood, the lower body stops growing, while the upper body spine continues to grow, eventually forming a standard adult body shape.

Height is largely determined by genes, but acquired nutrition is also very important. Especially during adolescence, to ensure the supply of nutrition, you can eat more beans, fish, eggs and other foods. You should also exercise every day to strengthen your bones. In addition, sleep also has an important impact on a person's height. If you want to grow taller, you must get enough sleep every day.
