Generally speaking, the height will stop growing after the bone age closes, but the individual difference is big, so the difference of the age of stopping the growth is also big, usually, the male stops growing at the age of 20~24, and the female stops growing at the age of about 19~23. Human height increases with the growth and development of bones, and if the bones stop developing, the height will be fixed. The mechanism of growing taller is that the epiphyseal cartilage keeps growing and the bones keep growing until the epiphyseal cartilage no longer grows, and the diaphysis and the femoral epiphysis are connected to form an epiphyseal line, and if the epiphyseal line is completely closed, the bones will stop growing. Males usually stop growing around the age of 20 to 24 years old, because male height develops later and the period of rapid growth is 15 to 16 years old, while females usually stop growing at the age of 19 to 23 years old, due to the fact that female height develops relatively early and the period of rapid growth is at the age of 12 to 13 years old. However, height is affected by many factors, including genetics, exercise, nutrition, living environment, endocrine and other factors. Daily attention to maintain a reasonable diet, a healthy lifestyle and good mood, to ensure enough sleep, is conducive to the secretion of growth hormone, daily consumption of food rich in energy, protein and amino acids, supplementation of micronutrients, to strengthen the body’s metabolism, easy to grow taller.
