0~2 years old: the annual height growth of children will be greater than 10 cm.
2~4 years old: the annual growth rate is about 5.5~9 cm.
4~6 years old: the annual growth rate is about 5~8.5 cm.
After the age of 6 to before puberty: it will grow a little slower, with boys growing about 4~6 cm and girls growing about 4.5~6.5 cm.
When children reach puberty, a growth peak begins to appear. Under the synergistic effect of sex hormones and growth hormones, girls can grow about 78 cm a year on average, while boys can grow about 9~ 1 1 cm.
Real case
/kloc-Xiaotian, 0/2 years old, is now in Grade One, and Xiaotian, with good grades, successfully advanced to the provincial key experimental middle school when he was promoted from primary school to junior high school, while Xiaotian was an obedient and sensible child since childhood and never let his parents worry about it, but there is one thing that makes Xiaotian's parents pay special attention to and worry about, that is, the height of the child.
Xiaotian's parents are not short, father 178 cm, mother 167 cm. According to common sense, children are not short in this height ratio, but when Xiaotian was in kindergarten, he was much shorter than his peers.
This makes Xiaotian's parents very sad. They will try their best to make their sons grow taller, fearing that their children will be eliminated by society because of their height when they grow up.
Therefore, Xiaotian's mother will let her children drink a cup of warm milk before going to bed every night, and so she has been drinking milk for three years. At first, she thought that her height would be by going up one flight of stairs, but the result was very surprising. Xiaotian's height not only failed to surpass that of her peers, but also only grew by about one centimeter in three years.
At this time, Xiaotian's mother was so anxious that she quickly took her child to a regular hospital for examination. At this time, it was discovered through examination that the child had indigestion in the gastrointestinal tract because of drinking milk before going to bed for a long time.
Zinc deficiency also appeared in the body, so Xiaotian was picky about food and didn't like to eat, which caused her nutrition to fall behind, so her height development was affected to some extent.
Therefore, the surgeon said: various organs in the body need a lot of zinc, and zinc is needed for the growth and development of the body, gastrointestinal peristalsis and digestion, as well as for the long body.
If the body lacks a large amount of zinc, it will lead to the body's insufficient intake of various nutrients, which will lead to a series of stunted height.
Because Xiaotian's mother always asks her children to drink a cup of warm milk before going to bed every night, which increases the burden on their children's gastrointestinal tract and causes a very serious problem of food accumulation. In fact, drinking milk does help their children grow taller, but when it comes to falling asleep immediately after drinking milk, it will bring a very serious burden to their gastrointestinal tract.
If everyone drinks milk before going to bed for the purpose of growing taller, it is best to take a proper rest before going to bed, and then go to sleep after finishing, giving the gastrointestinal tract a proper relaxation time, so that the effect of growing taller will be more.
Usually, about 70%~85% of the average person's height depends on his own genetic factors, which are similar in the morning and evening of puberty development.
The nutritional mood of the mother during pregnancy, the condition of uterus and placenta, whether there is pregnancy-induced hypertension and diabetes, etc., will also affect the congenital height of the child to a certain extent.
In addition to genetic factors in the family, there are also disease factors, education factors, nutrition, exercise, sleep psychology and environmental factors. Children born to the same parents will have certain differences in height, so even if their parents are very tall, their children may not be very tall in the future. This requires everyone to do a good job in height monitoring before they can judge.
Nowadays, primary school students generally have a lot of homework, and their study pressure is also great. It is common for them to study late into the night. As we all know, sleep is one of the important factors affecting their height.
The growth hormone secreted by children's bodies during the growing period helps them grow taller, while the growth hormone in children's bodies is mainly secreted at night, and it will only be secreted when the children are asleep, so there are usually 5~6 secretory pulse peaks throughout the night, which is a kind of pulsed secretion.
The 1 th secretion peak is usually around 10 in the evening, provided that the peak of growth hormone secretion will gradually appear after sleeping. If the child is not asleep at 10:00, or is still doing homework, playing with toys, watching TV and other phenomena, the growth hormone will not be secreted.
Then it will secrete less growth hormone than children of the same age. Long-term lack of growth hormone will have an impact on their height, so parents are advised to let their children fall asleep as soon as possible every night.
-exercise
Parents should encourage their children to take part in more sports, because people can not only help stretch muscles, but also promote the development and perfection of bones during exercise, so if you want to grow taller, you can also make your body strong.
-diet
Today's children will be more stressed than before. If you want to grow taller, you can't lack nutritional intake. The most direct way to grow taller is to adjust your diet, so parents can usually give their children more calcium-rich foods.
-decompression
If the child continues to grow under the pressure, it will affect the secretion of hormones in the body, which will lead to the phenomenon of not being able to grow taller, so it is necessary to relieve the pressure on the child appropriately.
