The peak periods of height growth include infancy and adolescence, i.e., 0-1 year and puberty, with slight differences between boys and girls. Human height growth includes two peak periods, namely infancy and adolescence. Infancy is 0-1 years old, with height growth of about 25 cm in the first year, 10-12 cm in the second year, and 6-7 cm per year after the age of 2. A second peak in height growth occurs during puberty, when adolescents gain rapid height growth again. After puberty, the child’s height basically reaches adult level. During the peak of height growth in infants and adolescents, it is important to ensure adequate and balanced nutrition supply and sufficient sleep. In addition, moderate physical exercise can enhance appetite, improve sleep quality and promote the deposition of calcium in bones, which is beneficial to height growth.
