What kind of circumstances suggest puberty? When it comes to adolescence, everyone will definitely think of girls coming to menstruation, boys changing their voices and Adam's apple. However, this is the late adolescence, which really indicates that girls look at their breasts and boys look at their testicles.
Usually girls start puberty at the age of 10- 12. The development order of female students is breast induration, then enlargement, then pubic hair, armpit hair, and finally menstruation.
Boys begin to show signs of puberty at the age of 12- 14. First, the testicles are enlarged (compared with girls, boys' puberty begins to be hidden and easy to be ignored), then the penis becomes longer and thicker, pubic hair and axillary hair appear again, then the voice changes and Adam's apple appears, and finally nocturnal emission.
The influence of adolescence on height. The arrival of adolescence will make children enter a high growth period. During the whole adolescence, the total height can be increased by 20-25cm, because the onset time of puberty of boys is about 2 years later than that of girls, and the growth rate of boys in adolescence is slightly higher than that of girls. Therefore, the ultimate height of adult males is about 12.5cm higher than that of older females.
The influence of adolescence on unhealthy height
The appearance and duration of adolescence play a great role in the final height of children.
If puberty occurs early, such as before the age of 8 for girls and before the age of 9 for boys, it is medically considered as precocious puberty. In this case, the child's growth space is damaged, and the ultimate height will be affected. Even if the child's height is within the normal range or even higher before development, this can explain why many children around him are always tall at ordinary times, but the ultimate height after adulthood is not high. A big reason is that children develop ahead of time, especially girls.
This can also explain that many boys are not tall at first, but suddenly grow very fast at a certain age and eventually grow very tall. That's because these boys develop late, the basic height in front of them has accumulated for a long time, and the development in the back has lasted for a long time, and finally the whole long time is much longer than others.
There are also some children who are usually average in height, and puberty does not start early, but the whole adolescence is too short, so they develop too fast, and sometimes their height will eventually be damaged, which is called rapid progress of adolescence in medicine.
Therefore, if you want your child to grow taller, you should not only pay attention to the usual height growth, but also pay close attention to the child's development, find abnormal problems in time, intervene in advance, and avoid regretting the best intervention opportunity for life.
