What physiological knowledge do men need to know after puberty?
I was deeply impressed by a small detail when I looked at pi. When the basketball team in the experimental class wanted to recruit players, a little boy raised his hand excitedly and stood up and said, "I'll sign up." Jiang Tianhao, who is in charge of recruitment, looked at the distressed little boy, touched his head and said, "Stop it, wait until you grow up." When the little boy heard Jiang Tianhao say this, he instantly faded like a frosted eggplant.

Although the TV series is set to increase the funny effect, it also tells us the fact that adolescent boys have their own unique development laws. If parents can't guide their children correctly, short-term developmental delay is likely to cause their children's long-term inferiority complex. Then, as parents, they should tell their children such little physiological knowledge before puberty, so as to avoid their inferiority complex and help them get through adolescence smoothly.

0 1 Why am I so short? Lin Lin, a junior three student, won the first place in the final exam, which really envied his classmates, but a physical examination at school before the holiday made him embarrassed. It turned out that the teacher asked everyone to wait in line on the playground for a physical examination. Boys and girls are arranged in order from short to high. Lin Lin ranked first as usual. The nurse began the physical examination. The young nurse saw Linlin and looked at the girl next to her. She joked, "Hey, everyone is standing in the front row. The boy is much shorter than the girl next to him. Do you usually eat badly? " The nurse played an unintentional joke.

It is normal for children to know that many boys are not as tall as girls in adolescence, because girls suddenly grow taller two years earlier than boys. During the period of 1 1- 13, girls are generally taller than boys of the same age, but when they reach the age of 14- 16, the height speed of boys will accelerate. The growth stops later, so usually by the end of adolescence, the height of boys will obviously exceed that of girls of the same age by about 10- 13CM.

Many boys will find that their limbs will grow rapidly in the middle of adolescence, which seems to be incompatible with their height and thus become very inferior. In fact, when the height of adolescence increases sharply, the upper and lower limbs will grow faster than the spine, and the ratio of sitting height to height will gradually decrease, but this situation will change in the later period of adolescence, when the ratio of children's height to sitting height will reach the normal standard of adults.

So if you realize that your adolescent boy is too short to feel inferior, you must tell him loudly:

Children, don't be depressed, don't feel inferior, just strut like a man and strengthen physical exercise, and you will grow into a proud tall man in a few years.

02. Why do boys' breasts develop? Jiang Jiang is a boy of 15 years old. When he got up one morning, he felt a little pain in his chest. He felt a small lump when he touched it with his hand. He took off his clothes and observed that the color around the nipple was darker than before, and the area of the areola was larger than before. What is the reason? After coming to school, he quietly observed the girls in the class and found that the girls' breasts began to bulge, while the boys' breasts were very flat, which showed that the physical development of boys and girls was different, but why did he do it?

What children should know is that we all think that only girls' breasts will begin to develop during adolescence. In fact, boys may also have breast enhancement or development during adolescence, but many boys have this physiological phenomenon and are habitually ignored. Don't be embarrassed when boys encounter this situation. Be sure to tell your parents in time and let them accompany you to the hospital. If it is a normal adolescent development, it generally does not need treatment, and it will disappear by itself within 1-2 years.

At this time, we must tell our children:

Don't worry about this situation. This kind of physical development fully shows that you are growing, and your body is becoming mature and more and more like a real man.

03. Why does my body stink? Yang Yang likes basketball very much. During the summer vacation, Yang Yang's mother enrolled her children in a basketball training class. After several days of training, Yang Yang quickly learned some new pitching skills. With developed "sports cells", he is like a duck to water on the basketball court and becomes stronger. Yang Yang also became more and more fond of playing basketball. However, although Yang Yang is proud in the sports field, he also has some troubles in his life. I invited some classmates to go out to play together two days ago. One of the girls covered her nose rudely, saying that he smelled bad, and that he didn't care about hygiene and didn't like taking a bath. In fact, this can be wronged Yang Yang. Every time he finishes exercise, he will smell the sweat on his body, but he doesn't care. He takes a bath every day when he comes home, and he also uses shower gel specially. It's still delicious when you go out, but it smells when you sweat. Why is this happening?

What children should know is that human skin actually has two kinds of sweat glands, one is eccrine gland and the other is apocrine gland. Eccrine glands are distributed in all parts of the body, while apocrine glands are distributed in armpits, around anus and genitals.

When the child is young, the apocrine glands are not developed, and naturally they will not produce corresponding secretions. But after puberty, apocrine glands begin to develop. In summer, armpits, hands, feet and genitals will sweat more easily, so some unpleasant smells will be produced. When people get old, the secretion function of sweat glands will gradually decrease, sweat will also decrease accordingly, and the unpleasant smell of the body will be much less.

In fact, this situation can also be solved by daily diet and improving personal hygiene. Do more cleaning, change clothes frequently, wear pure cotton, comfortable, loose and breathable clothes and comfortable, light and breathable shoes. If you don't eat spicy food, smoke or drink alcohol, you can naturally improve your diet.

04. Why did the hair suddenly start to flourish? Recently, Hao Hao's mouth and chin began to grow beards. At first, there were only a few. He didn't care, but he didn't expect more and more moustaches on his face. In desperation, he had to pull out his moustache one by one with his mother's eyebrow plucking clip. But I didn't expect the beard to grow back just two days after pulling it out. Not only that, but also some thick hair began to grow under the armpits, legs and private parts of the body. He asked his classmates everywhere if they had a good depilatory cream, trying to get rid of all the hair on his body.

What children need to know is that when boys reach the age of 10- 14, their beards will grow wildly. At this time, they can shave with a razor, but never use tweezers to clip their beards, because they can only pull out hair shafts and roots, but not hair balls, nipples and hair follicles, which will not only prevent hair growth, but also damage the skin, hair follicles and adjacent areas.

The hair on the body begins to flourish, which is one of the characteristics of the physical development of teenagers. These body hair, armpit hair and pubic hair flourish because they represent the secondary sexual characteristics and physical needs of human beings. They can protect the skin and genitals from foreign bacteria and dust.

At this time, we must tell children that these hairs are the characteristics of male bodybuilding, so let them grow naturally, which represents their gradual development from "boy" to "man" and is also a unique symbol of men.

05. Why is your voice hoarse? Jay likes music since he was a child and sings very well. He is also the representative of the music class in his class. I like to practice some singles when I am free, and he always leads the music class.

It's time for music class again. When he got up in the morning, Jay found that his voice was a little wrong, a little tight and a little hoarse. At first, he thought he had a cold, but when he went to school to chat with his classmates, everyone teased him that his voice sounded like Donald Duck. Embarrassed Jay had to keep quiet all morning, and he also said that he caught a cold in the music class and didn't take the lead.

Let children know that every 12- 14-year-old boy has to go through a physiological voice change stage, which is called "voice change stage" in medicine. During this period, the boy's Adam's apple will become bigger, the vocal cords will become longer, and the voice is generally lower than before, so it sounds a bit rough. This is a normal transition period of adolescent voice change and a sign of growth.

At the beginning of the voice change period, the voice may not change much, and talking and singing may still be children's voices, but you will obviously feel that you have lost control of the voice, and sometimes the high notes can't go up and last; In the middle stage, the voice changes obviously, the voice components of children gradually decrease, the voice components of adults gradually increase, and the tone becomes low and rough; In the later stage of voice change, the voice may become completely like an adult, but after a period of time, it will be difficult to control the tone and the voice will be unstable.

It is very important to protect your voice at this time. Don't make your voice too tired, don't talk too much for a long time, and don't eat spicy food. It's best not to smoke or drink, and do more exercise to enhance immunity. After the vocal cords are developed, the voice will naturally calm down and become low and magnetic.

Adolescence marks the transition from boy to man. During this period, there will be many obvious changes in boys' physiology and psychology. As parents, we should give our children more physiological knowledge, communicate with them more, know their psychological state in time, help them arrange their study and rest reasonably, and supplement their nutrition more, so as to lay a good foundation for their lifelong health.
