What changes do people have after puberty? How to protect the body and make it develop healthily at this stage?

What changes do people have after puberty? At this stage, how to protect the body and make it develop healthily? When a man enters puberty, the first sign is swelling of testis and scrotum. As the testis matures, it begins to have the ability to produce * * * and androgen. Under the action of androgen, male genitals develop rapidly and appear secondary sexual characteristics, such as strong body, muscular body, small shoulders and hips, long facial beard, raised Adam's apple and low voice. Men's beards are the result of androgen. There is also a process in the appearance and shaping of men's beards. Only when puberty is over, sex is mature, and the androgen in men reaches the level of normal adults, the beard will increase to the appearance of adults.

Find someone to beat yourself every day for a long time, and then your body will get used to being beaten and become stronger.

How to protect health "health care" is to protect health. Traditional health means that a person's physiological function is good and there are no diseases or symptoms. This formulation is one-sided and incorrect. The World Health Organization puts forward that "health is not only the absence of physical diseases, but also mental health, good social adaptation and moral health". This is a comprehensive health standard. 1. Strong resistance and immunity, not easy to get sick. Once you are infected with the disease, you should have faster recovery ability. In 1950s and 1960s, China's "health care" measures were passive, mainly relying on doctors. Nowadays, health has become an important symbol of social progress. Protecting health is also the main aspect of human self-awakening and the basis of improving the quality of life. Therefore, we should change our ideas today, prevent diseases and treat them before they are cured. 1978, the world health organization (who) put forward "health for all in the year 2000", which indicates that in the second1century, there will be a health care craze focusing on preventive health care all over the world. The goal of medical treatment will not only cure diseases, but also prevent diseases and maintain people's physical and mental health. Specific health care measures: 1. Pay attention to personal hygiene, environmental hygiene, and wear comfortably. 2. Have a comprehensive and balanced nutritious diet to provide all kinds of substances and energy needed by the human body. Man is a living organism, constantly undergoing metabolism and constantly renewing all kinds of cells. That is to say, all kinds of life-sustaining nutrients in the original body are constantly consumed and need to be constantly supplemented to maintain good health. Insufficient nutritional supplements will definitely lead to poor health and even various pathologies. The ancients in our country have long recognized this point. Li Dongyuan, the author of Spleen and Stomach, a famous physician, thinks that spleen and stomach are the most important part of human physiological activities, and puts forward the view that all diseases are caused by internal injuries of spleen and stomach. Because his diagnosis and treatment of many diseases started with "strengthening the spleen and stomach and helping digestion", he cured many intractable diseases and became a famous doctor. China's classical medical books also recorded that "the kidney is the innate foundation, and the spleen and stomach are the acquired foundation". It means that nature is inherited by parents and acquired by spleen and stomach. For example, when a child is born, he is healthy and everything is normal. That's her parents' genetic health. This is innate strength. Therefore, after birth, in order to keep him in a healthy body and let him grow up healthily, it is necessary to have a comprehensive and balanced nutritional feeding, a material supply for generating qi and blood, and the cooperation of digestion and absorption of various nutrients by the spleen and stomach, otherwise it is impossible. Without adequate nutrition to supplement the body's consumption, the physique will get worse and worse. Some people think that living conditions are good, food is good and nutrition is enough. But I can say for sure that you can't eat all the nutrients you need, and you may even get sick. Because the nutrition that people need is comprehensive and balanced, they can't be without it, and they can't be excessive. At present, many so-called "rich diseases" such as diabetes, obesity, hyperlipidemia and hypertension are closely related to unreasonable diet. People still have a misunderstanding that eating high-calorie food has high nutritional value. Actually, it's not. Eating comprehensive and balanced nutrients can be healthy. 3. Exercise properly. Exercise can promote blood circulation, increase appetite, enhance metabolism, and also help the human body to absorb and utilize nutrients in food. "Life lies in exercise", and exercise can lead to a long and healthy life. So many people exercise in parks and other places. But we can't ignore the supplement of nutrients. As the saying goes, "water without a source, wood without a root". If only exercise consumes physical strength, there is not enough nutritional supplement, the intake and expenditure are unbalanced, and the long-term immune function is low, various diseases will occur. Moderate exercise and excessive exercise are also harmful to your health. We 70-year-olds are all from the old society. In our adolescence, the average life expectancy of China people is only over 40 years old, and there is the ugly title of "Sick Man of East Asia". At that time, the working people had great labor intensity, excessive body consumption, insufficient nutrition supplement and long-term overdraft, so they died early. Of course, there are many other factors, but the internal factor is the decisive factor, and the lack of healthy qi is the main one. Traditional Chinese medicine has long recorded that "the combination of evil causes qi deficiency", "Yin and Pingyang are the secret, God is the cure, and God is hidden inside, so the disease is always safe". 4. Having a peaceful and happy attitude is an important sign of mental health. Mental health can delay aging and enhance immunity. Epidemiology has long reported that the incidence of cancer is directly related to war. During the war years, the incidence of cancer was high in many countries. During the China 10 disaster, many veteran cadres died of cancer, which was related to the imbalance of mentality. Because everyone has cancer cells, when you are strong, cancer cells are in a state of sleep, and it is common to live with cancer for many years in clinic. When your immune function is low, cancer cells become active and can invade various organs of the human body and cause cancer. So when you are alive, don't haggle over every ounce and compare yourself excessively. A contented mind is perpetual feast. 5. Have proper rest and adequate sleep. Sleep can make the human body self-regulate, recover fatigue, improve immune function, don't be too nervous, pay attention to the combination of work and rest. 6. Regular physical examination. Early detection of hidden dangers, early treatment. 7. Quit bad habits. Like smoking and drinking. 8. control medication. It's a three-point poison. Taking medicine will increase the burden on the liver, especially sleeping pills. However, the elderly have some diseases, so we should try our best to change from drug treatment to non-drug treatment.

This is all a little common sense,

What should we pay attention to when entering adolescence? Physiological changes of adolescent men and women;

Growing teenagers will experience a series of physical changes. No matter how fast or slow the changes they experience, they may feel unnatural or inferior to others. In fact, everyone's growth speed and time will not be exactly the same. If we can understand the puberty stage of men and women first and make psychological preparations, we can meet the new changes.

1. Primary sexual characteristics: The different characteristics of male and female infants' external genitalia can distinguish their sex and are regarded as primary sexual characteristics.

2. Secondary sexual characteristics: From adolescence to adulthood, gonads secrete hormones in the pituitary gland, which makes men and women have significant differences in many physical characteristics and shapes, and develops their gender characteristics, which is called secondary sexual characteristics.

3. Comparison of puberty between men and women

Women and men with secondary sexual characteristics

Start to increase 8- 13 10- 15.

* * * development, * * increase by 8- 14 12- 15.

Body hair appears 8- 15 9- 15.

First visit 9- 16

Ovulation begins 10- 16

Development of reproductive system

Voice change 1 1- 17

Manufacturing *** 1 1- 17

Grow a beard 1 1- 18

Bone growth completed15-1918-22

4. Five stages of female adolescence

Stage age, chest visceral growth, menstruation

18- 1 1 Ovary enlarges and secretes estrogen. There are no special circumstances.

28 ~ 14, the estrogen sinus in the blood developed obviously, with prominent, soft and rapid growth; The hips become wider and the fat increases, which makes the body softer and rounder and begins to grow flat, soft and sparse.

3 9- 15 *** becomes larger; The secretion changes of * * * continue to develop, the areola becomes larger, the height and weight increase, the oil secretion increases, acne may grow, the color becomes darker, and * * * becomes thicker, but it is still sparse. Menstruation may begin at this stage.

4 10- 16 ovary enlargement; It is possible to start ovulation, and the areola and * * * protrusion continue to grow * * * looks similar to adults, but the coverage area is small; Axillary hair began to appear. If there is still no menstruation at the end of phase 3, start at this time; Menstruation at this stage usually does not ovulate.

5 12- 19 The ovary matures and the ovulation rule is completed. Adults are close to adults in height and look like adults. At the end of the period, menstruation is regular and ovulation occurs.

5. Five stages of male adolescence

Stage, age, growth of internal organs, hair, etc.

1 9- 12 androgen began to be active, with no obvious change, and the testis began to mature. Some people grow rapidly at the end of this stage without * * * or other body hair.

The change of 2 9- 15 hormone increases muscle tissue and fat, which leads to the change of body shape and the enlargement of testis and scrotum, but * * * does not increase obviously, but the height increases rapidly and the physique changes greatly. Straight and thin areola appears at the root of * * *, slightly larger and darker.

The length of 3 1 1- 16 * * increased, the muscle tissue of testis and scrotum continued to increase, and the shoulders became wider and thicker, covering the roots of * * * *; The upper lip begins to grow a beard and the throat is developed, which makes the voice low.

4 1 1- 17 began to widen the width of * * * *, the testicles continued to grow, armpit hair and beard increased, * * * looked like an adult, his voice deepened and his skin became oily.

5 14- 18 looks like an adult after development, and its height is close to that of an adult. * * * is no different from adults, and the beard may grow chest hair or body hair in the future.

Adolescence is the transition stage of children and adolescents to adults, showing a naive and immature state.

The following psychological changes can occur: (1) sexual consciousness is enhanced; (2) gradually enhance the sense of independence and have a sense of adulthood; (3) close yourself and keep your inner world; (4) One-sidedness of cognitive problems is easy to occur.

When a girl enters puberty, great changes will take place in her physiology. Especially the girls of 12 ~ 17 are in the pre-puberty, their bodies have changed greatly, their weight will also increase, and their appearance will also change to a great extent. Generally speaking, the height should be increased by about 10 cm, and the weight should be increased by about 7 ~ 8 kg. All organs except lymphoid tissue are swollen, and menstruation is coming. The energy consumed by the whole body every day is 1.25 times that of adults. Therefore, adolescent girls must eat a lot of carbohydrates, and they must also eat enough calcium, iron, vitamin A, thiamine, riboflavin, nicotinic acid, ascorbic acid and so on. If malnutrition occurs during this period, young girls will be short stature, stunted or stunted, late menstruation, and even weak or deformed.

Daily nutritional requirements of adolescent girls

Adolescent girls are active and grow rapidly, so the demand for various nutrients is bound to increase. In addition to adequate carbohydrates, protein 70 ~ 90 mg, calcium 1 ~ 1.5 mg, iron 13 ~ 17 mg, vitamin A2200 ~ 2500 IU or carotene 3 ~ 5 mg, and vitamin B/kloc should be supplemented. Vitamin B2 1. 1 ~ 1.6 mg, nicotinic acid 13 ~ 18 mg, vitamin C 70 ~ 100 mg, vitamin D 400~800 international units and other vitamins and minerals. Only by taking enough nutrition can we ensure the growth of girls, otherwise there will be symptoms such as nutritional deficiency and stunting. However, if girls consume too much nutrition every day, then too much nutrition will be converted into fat and stored in the body, which will make girls fat and affect the balanced development and physical beauty of the body.

Adolescent sexual health care for girls

* * * Health care

The development of adolescence marks the beginning of a girl's maturity. The convex * * * also reflects the unique curvaceous beauty and healthy beauty of women's mature figure. And prepared conditions for breastfeeding the baby in the future. Therefore, the protection and health care of * * * is the main aspect of female adolescent health. * * * Some phenomena in development may cause confusion and anxiety of girls, such as whether to wear a bra or not. * * * is stunted, * * * is too small or too big, * * * is asymmetrical on both sides, * * * is deformed, and * * * is a mass. The following are the suggestions of health care doctors.

Girls shouldn't wear corsets.

Adolescent girls should never wear tight underwear. Girdling is harmful to girls' development and health. First, the heart, lungs and great vessels are compressed when the chest is tied, thus affecting the normal development of internal organs of the body. Second, girdling the abdomen will affect the respiratory function. Under normal circumstances, chest breathing and abdominal breathing cooperate to ensure the normal gas exchange of human body; However, the embrace of the chest affects the chest breathing, so that the chest can not be fully expanded, the lung tissue can not be fully extended, and the amount of inhaled air is reduced, which affects the supply of oxygen to the whole body. Third, the corset compresses * * *, which makes the blood circulation not smooth, leading to congestion in the lower part of * * *, causing pain, swelling and discomfort of * * *, and even causing * * * invagination, stunting of * * *, affecting bodybuilding, and also causing difficulties in breastfeeding in the future. Therefore, it is necessary to repeatedly publicize the dangers of corsets. Girls should be encouraged to tell their mothers about the development of * * * so as to get necessary health care guidance in time.

(2) Wear a suitable bra

* * * After the development is basically finalized, it is necessary to promptly guide girls to choose and wear appropriate bras. Girls' * * * development is basically stereotyped at 15 years old, but there are great individual differences. Under normal circumstances, you can use a soft ruler to measure from the upper edge of * * * to the lower edge, and you can wear a bra when the upper and lower distance is greater than 16 cm.

Wearing a bra has the following advantages: first, it shows the beauty of women's bodies; Second, support * * * to prevent sagging; Third, it can prevent diseases caused by blood stasis in the lower part; Fourthly, reducing the local pressure of the heart, promoting the smooth blood circulation, is conducive to the development of lactation; Fifth, reduce the vibration caused by exercise or manual labor to avoid injury; Sixth, protect * * * from being scratched or bumped; Bras also keep warm in autumn and winter. In a word, bra is not only an ornament, but also a key product for women. Because girls are of different sizes, it is necessary to choose a bra of the right size and feel comfortable and not tight after wearing it. It is also necessary to change the bra at any time according to the fat and thin changes in physical development. Never blindly pursue the beauty of your figure and force yourself to wear an inappropriate bra. The texture of the bra should be soft and absorbent. Wash and change frequently and keep clean. Take off your bra when you sleep at night. Get into the habit of wearing a bra. No matter spring, summer, autumn and winter, stick to the old age.

(3) Health * * *

Adolescent girls, due to endocrine reasons, may have * * * swelling pain and * * * itching pain before and after menstrual cycle. At this time, girls should not just squeeze and pick * * *, so as not to cause breach and infection. Always clean areola, * * *. Because there are many glands in the areola, it will secrete oily substances, which can protect the skin, but it will also be contaminated with dirt and cause redness, so it should be kept clean and hygienic.

(4) *** Dysplasia If you find that * * * is too small or too big, bilateral * * * is uneven, * * * is underdeveloped, * * * is deformed, and * * * is a lump, don't panic. If these situations are found, firstly, bodybuilding can promote the development of chest muscles and make * * * look plump; Second, proper treatment should be carried out under the guidance of a doctor. Girls can't determine whether * * * is stunted until they are physically developed and sexually mature. Don't jump to conclusions

Menstrual care

Girls are often scared by the first oozing blood; When you know that it is normal menarche, you may be at a loss about how to deal with menstruation. Therefore, it is necessary to learn menstrual hygiene knowledge before menarche.

Menstruation is a process in which women's endometrium is exfoliated and menstrual blood is discharged from * * * *. During menstruation, because the endometrium falls off, a wound is formed, and the normal acidic environment in * * * may also be diluted by menstrual blood seepage. At the same time, the cervix is slightly open, and pelvic congestion leads to the decline of local defense function of reproductive organs. If you don't pay attention to hygiene, bacteria can easily invade the reproductive organs. During the menstrual period, girls' brain excitability decreases, their whole body resistance decreases, and they are prone to fatigue, colds or other diseases. Therefore, girls should be instructed to pay attention to the following aspects of health care during menstruation.

(1) Keep the vulva clean. Wash vulva with clean warm water frequently to avoid scabbing during menstruation. When cleaning vulva, don't soak your lower body in water. To prevent dirty water from infiltrating into * * *. Can't wash vulva with foot towel and feet. The basin for washing vulva should also be separated from the footbath. Wipe the toilet paper from front to back after defecation to avoid bringing the bacteria around * * * to the vulva.

(2) Maintain an optimistic and stable mood. During menstruation, girls often feel irritable, irritable or depressed because of some physical discomfort, such as breast fullness, backache, abdominal distension and headache. Emotional fluctuations in turn affect menstruation. Maintaining a good mood and self-regulating emotions can reduce menstrual discomfort and prevent menstrual disorders.

(3) Properly control the amount of exercise. Pay attention to rest during menstruation, keep enough sleep and enhance the body's resistance. Avoid strenuous exercise and heavy physical labor. If female students go to physical education class during menstruation, they can explain the situation to the teacher and take part in some relaxing sports, such as gymnastics, walking, playing badminton or table tennis.

(4) Keep warm. During menstruation, the body's resistance drops and the pelvic cavity is congested. Keep warm. Avoid getting wet in the rain, wading, swimming or taking a bath with cold water, washing your hair and feet, and it is best not to sit on the wet ground. Don't drink too many cold drinks in summer to avoid catching cold, catching cold, and contracting pelvic blood vessels, which may lead to menstrual decrease or sudden menopause, which may lead to other diseases.

(5) Pay attention to food hygiene and strengthen nutrition. During menstruation, you can eat some foods that are easy to digest and absorb, such as eggs, lean meat, bean products, vegetables and fruits. At the same time, drink plenty of boiled water, increase the frequency of urination, and flush the urethra to prevent inflammation. Do not eat cold and spicy food, keep the stool unobstructed and reduce pelvic congestion.

(6) Keep a record of menstrual cycle. By recording, you can observe your menstrual regularity or not, and it is also convenient to prepare for menstruation. If menstruation does not come according to the date, you should go to the doctor in time to find out the reason.

Will be healthy.

Adolescent girls are in the stage of vigorous metabolism, and sweat glands and sebaceous glands secrete more, nourishing the surrounding skin. It is easy to accumulate dirt on the wrinkled wall, especially for the fatter girls. In addition, due to the active ovarian function in adolescence, the secretion of * * * increases, and the vulva is close to * * * or urethra, which is easily polluted by urine and feces. These reasons will cause girls' vulva itching, and also cause secondary infection and folliculitis. Long-term itching may lead to insomnia, haggard, anxiety and high tension. Therefore, social health is very important.

First, wash the vulva with warm water every night. Generally, disinfectants such as potassium permanganate are not needed to avoid vulva and * * *.

Second, the basin, towel and water for cleaning vulva should be used alone, and should not be mixed with the basin, towel and water for washing feet;

Third, don't wear other people's * * *, choose cotton fabric with good air permeability and strong hygroscopicity for your own * * *;

Fourth, develop the habit of wiping toilet paper from front to back to prevent bacteria from entering the mouth;

Fifth, pay attention to menstrual hygiene; Sixth, if there is a large amount of leucorrhea, and there is an odor or blood color, you should go to the hospital for examination and treatment in time to avoid causing * * * infection and vulvar itching.

Adolescent boys can do it as long as they exercise more, have a balanced nutrition intake and get enough sleep.
