Parental love is the best encouragement for all children, such as academic performance, being a man and growing taller. It is very important to give them endless love, constant encouragement, scientific efforts and persistence to make them confident and grow taller.
How to judge whether the height of teenagers is normal?
Teacher Gao, who helps manage health, pointed out that the height of adolescence plays a decisive role in a person's final height. In adolescence, the height of the human body shows a trend of rapid growth, and there are obvious gender differences in the beginning and end of the sudden increase period, the extent and the key parts of the sudden increase, so the methods for girls to grow taller quickly are different from those of boys. Kicking shuttlecock is also a good way to grow taller in the crowd. In others' eyes, it's like enjoying dancing. Skeletal joints, knee joints, stomping joints, etc. Swing around the longitudinal axis to drive the most difficult part of the distal end to supply blood and exercise, and enhance the muscle strength and flexibility of the corresponding joints, thus reaching the height standard.
Teenagers of all ages should have healthy height standards, which are generally obtained from cross-sectional survey data of representative healthy teenagers in China. With the improvement of living conditions and health care, these standards have also improved. However, it should be pointed out that the so-called normal standard value is a statistical average, and the figures adjacent to the average value are all within the normal range. When we use the suitability of such standards, we need to look at it with a scientific concept of development, and we can't stick to a certain high standard and analyze the specific situation.
The three most critical periods of growth and height
Teacher Gao, who helps with health management, pointed out that a person is in the process of continuous growth and development from the beginning of egg fertilization and is regulated by many factors. Although growth and development is a relative replication problem, everyone will follow certain growth laws. Generally speaking, people will experience three periods of rapid growth in height.
The first period: rapid growth period (infancy)
Children grow up quickly from birth to 2 years old, which is mainly influenced by the growth of the fetus in the uterus during pregnancy. The growth rate is the fastest in the first year after birth, which can increase by 25 cm, and the growth rate in the second year is 10 cm.
The second period: the growth rate slows down (before puberty)
From the age of 3 to puberty (about 10 for girls and 12 for boys), the growth of this period is mainly regulated by growth hormone, increasing by 5~7 cm every day.
The third stage: growth acceleration period (adolescence)
Due to the regulation of growth hormone and sex hormone, the growth of boys and girls accelerates again after puberty, in which growth hormone plays a leading role in human growth, and sex hormone not only promotes growth, but also promotes sexual maturity and skeletal maturity, leading to the cessation of height growth. Boys can grow 25~28 cm in height throughout adolescence. The height of girls can be increased by about 25 cm.
What should teenagers do when they grow taller?
Results Eating habits should be healthy. The healthy development of girls needs high-quality protein, sufficient calories, calcium, zinc and various vitamins.
Maintain a good lifestyle. For example, sleep, as the saying goes, "sleep well, grow tall", without good sleep, will inhibit the secretion of hormones in girls, leading to stunting.
Exercise is indispensable. It is said that more than 50% girls in China lack exercise, and parents even ignore the importance of exercise. In this regard, parents should strengthen supervision and it is not easy to ignore it.
Mental factors are also important. Being in a bad mood will affect the brain and endocrine system, and then it will also affect the increase.
Sunbathing helps to grow taller. Ignoring sunlight will lead to vitamin D deficiency and amino acid loss, and it is difficult for girls to grow taller. So first of all, learn to bask in the sun scientifically: try to sunbathe your baby for 1~2 hours every day.
