Different tissues and organs of the body, the growth rate is different, there are first and later, fast and slow, not at the same time to stop growing. In general, the growth of a child’s height depends mainly on epiphyseal growth. Epiphyseal growth in the early mainly in the calves and thighs, to the late puberty, that is, the stage of high school, mainly in the spine, the growth of the spine at this time, if pay attention to the exercise and nutrition, can continue to increase in height by 4-6 centimeters. There are two stages of rapid height growth in the normal human growth process, the so-called growth spurt: infancy and puberty. In the first year of life, a newborn’s height increases by 25 centimeters, and in the second year by about 12 centimeters; during puberty, a child’s height increases by an average of 7-10 centimeters per year, a period that lasts about three years, with a total increase of 25-28 centimeters during this period. These two periods are critical in determining children’s height in adulthood, but during this time, children’s growth is affected by a variety of environmental conditions, which ultimately affects the fulfillment of a child’s genetically determined growth potential. In addition, compared to the two, puberty is more important, because the infant growth is affected, as long as the timely correction of various factors affecting the increase in height, the child still has enough time to “catch up with the growth”, and ultimately may be able to catch up with the age of the small friends. If the ability to catch up with the growth in the adolescent development period is limited, once you miss the golden period to increase height, it is too late to regret.
