What should adolescent boys pay attention to? Healthy. private mail

1. When a man reaches puberty, due to the maturity of sex education, under the action of androgen, he will have sexual demand and have a good impression on his wife. This is completely a psychological change accompanied by physical development in adolescence, which is a normal phenomenon, but the good impression at this time is extensive, blind, unstable and uncertain. If you don't handle it well, you lack proper sexual knowledge and don't pay attention to sexual morality, it is easy to cause physical and mental harm and make mistakes that should not be standardized. So some people call this period "the critical period of youth". 2. Adolescence is a critical period that determines the physical, mental and intellectual development of a lifetime. Although the body's resistance at this time is stronger than that in childhood, the law of suffering from infectious diseases is also great. Such as tuberculosis and hepatitis. It is not uncommon, but autonomic nervous dysfunction, thyroid disease, neurosis and so on. Obviously it's not just childhood. Therefore, adolescent health can not be ignored. Pay attention to nutrition, rest, study hard and exercise, so as to lay a good foundation for healthy nuclear work for life. "Sex" generates curiosity. This change of thought, mood and behavior is greatly influenced by cultural media and social factors, and is called the third characteristic. This aspect has no clear physiological basis, but is formed through the acquisition of social gender roles. 3. With the development of secondary sexual characteristics, teenagers have changed psychologically or physically. Generally speaking, people are anxious and irritable, and things they don't like are easier to lose their temper, but they are interested in the opposite sex and curious about sex. This psychological, emotional and behavioral change is greatly influenced by cultural media and social factors, and becomes the third sexual characteristic. This aspect has no clear physiological basis, but is formed through the acquisition of social gender roles. Adolescence refers to the stage when an individual's sexual function changes from immaturity to maturity. In biology, it refers to the transition period from immaturity to maturity, that is, the transition period from children to adults for men. During this period, my personality is mature and I can have children. It can be seen that adolescence is mainly divided into stages of physiological maturity, which overlaps with the stages of life divided from psychological or social aspects. In the stage of human growth and development, adolescence accounts for half or even more time. At present, there is no consistent age range in various countries, which generally refers to 13, 14-17 and 18 stages. Psychologically, it is also called pre-adolescence, which is equivalent to the middle school stage in pedagogy and is characterized by rapid physical growth. In addition to adolescence, adolescence will last until the age of 25-30. Because the sexual maturity of men is about one year later than that of women, it can be determined that the puberty age range of men is 14- 18 years old. 1 ~ 2 years too early or too late is normal. Men of this age are usually called boys, while women of the same age are called girls. In adolescence, there are not only obvious physiological changes, but also great psychological changes. Physical growth with sexual maturity as the main content has a great influence on the psychological and social aspects of teenagers, forming several important characteristics of this period: adolescence is a transitional period, and adolescence is a period for individuals to transition from children to adults. Usually, people clearly distinguish between adolescence and childhood, and the dividing line is sexual maturity. For men, the sign of sexual maturity is ejaculation (usually ejaculation during night sleep, that is, nocturnal emission, but also masturbation ejaculation); Women have menarche, that is, the first menstruation. The physiological development centered on sexual maturity makes teenagers have obviously different social and psychological characteristics from children. Individuals depend on adults in childhood, and adults constrain and decide the main contents and aspects of children's lives and activities; Children are not responsible for their actions. With the increase of age and the complexity of life scope and activities, teenagers have different characteristics from children. They gradually have a certain intention and sense of responsibility, and decide how to carry out certain activities by themselves. You should bear certain criminal responsibility for your actions, especially some criminal acts. But teenagers are also different from adults. Although they have some independence, they are not completely independent; In many ways, especially in material life, we have to rely on our parents; They have not yet become fully responsible persons and are not criminally responsible for all their actions. It can be seen that this transitional state between children and adults makes teenagers become marginalized people in sociology. The uncertainty of their identity and the uncertainty of social demands on them have caused many special mental health problems. Adolescence is a period of development. Adolescence is the period when human development is completed. Research shows that there are two stages in a person's life: the rapid growth of the body and the significant changes in the proportion of various parts of the body. One is in the prenatal period and the first half year after birth, and the other is adolescence. The rapid growth and development of adolescence is called the phenomenon of rapid growth of adolescence. In fact, this phenomenon begins before or at the same time as sexual maturity and ends six months to one year after sexual maturity.
