A series of morphological, physiological, biochemical, psychological and behavioral changes in adolescence are unmatched by other age stages in everyone's life. Especially the reproductive system (the last system in the whole body) develops rapidly in adolescence and reaches sexual maturity. These rapid changes are easy to cause psychological troubles and fluctuations. Although they may not necessarily lead to serious abnormalities, if they are not handled in time, they will also cause troubles, even affect lifelong health, study, work and behavior, and even endanger families and society in serious cases. Therefore, it is very important to pay attention to the mental health of teenagers. For the convenience of discussion, let's first make an overview of the physiological changes in adolescence.
First, the endocrine function of adolescence
The great changes in the structure and function of the human body in adolescence are caused by hormones. During adolescence, a part of the brain, the hypothalamus and pituitary gland, secretes almost the same hormones as adults. It leads to a series of amazing changes in the body: clothes are used up quickly, food intake suddenly increases, suddenly I find myself running fast and jumping high, and suddenly one day I find myself worrying, and I have a secret space in my heart that I don't want anyone to enter. These changes happen as quickly as the undercurrent of the sea floor. Do you feel it? In fact, it is precisely the secretion of hormones such as auxin, thyrotropin and gonadotropin that has reached a new level. Among them, auxin directly acts on tissues and cells of the whole body, which can increase the volume and quantity of cells and promote individual growth. The increase of thyroid hormone level caused by the increase of thyrotropin secretion can enhance the metabolic process of the whole body. Gonadotropin stimulates ovarian follicle development and testicular sperm production.
Second, the gender differences in adolescent posture
There are obvious gender differences in puberty physical development, sudden increase and key parts of change. The development level of women aged 9 ~ 10 is higher than that of men of the same age, and the development level index of men around 15 is higher than that of women of the same age. By the age of 18, men have reached a higher level than women in the absolute values of the above four indicators. In the end, men are taller, wider in shoulders, fuller in body and wider in buttocks.
Sooner or later, it will also cause changes in body shape. Early development stops early, and adulthood may be shorter and fatter than later development. Therefore, in adulthood, it often forms a body shape with narrow shoulders and wide pelvis. In the later stage of development, it often grows into a slender type with wide fertility and narrow pelvis. Therefore, during this period, we should pay special attention to reasonable diet and strengthen physical exercise.
Third, the physiological function is gradually enhanced.
The weight and volume of the brain are close to those of pre-adolescent adults, and the differentiation function of brain cells reaches the adult level. The improvement of this quality provides a material basis for individuals to adapt to the complex changes in the external world. At the same time, due to more and more social practice, the internal structure and function of the brain are constantly differentiated and developing rapidly. These changes have greatly improved teenagers' memory, understanding and thinking ability. At the same time, the heart grows rapidly, the myocardium thickens and the heart function improves significantly, which is very important to adapt to the increase of various activities.
Fourth, the reproductive system is mature
From 14 weeks, there are significant gender differences in fetuses. The main organ that directly promotes male sexual maturity is testis. Testis can secrete androgen, and its main function is to stimulate the development of male accessory organs and secondary sexual characteristics and maintain normal sexual desire. In adolescence, the secretion of androgen is obviously increased, and the stimulating organs are obviously developed. After male sexual maturity, nocturnal emission may occur. On this point, some time ago, in biology class, the teacher introduced the students. It is precisely because of the continuous production of sperm cells. Enuresis? It has become a symbolic signal of boys' physical maturity after puberty. At the same time, secondary sexual characteristics began to appear. The developmental sequence of male sexual maturity is: testicular development? Change your voice? Have nocturnal emission? The maximum growth rate of the body? Long body hair? Grow a beard. Including the initial pimples, that is? Acne? . The above physiological changes are so normal that they are all signs that you are beginning to mature, so there is no need to make a fuss. If you drink more water, eat more fruits and vegetables, and pay attention to clean skin, you can put that? Annoying? Small acne is controlled within a certain range.
From the above, it is not difficult to see that adolescence is indeed a crucial period in a person's life from childhood to adulthood. Today our middle school students are in this period. With the physiological changes in adolescence, teenagers' psychology has also undergone corresponding changes. For example, they realize that they are no longer children, like to act independently, like to make friends, and their sexual consciousness begins to sprout, and they are curious and interested in the opposite sex. At this time, boys and girls often look forward to a new life course, and their inner world often conflicts with the external environment from society, facing many questions and puzzles about life topics. Therefore, students who are bidding farewell to childhood and starting to enter adolescence, how to successfully spend adolescence and grow up healthily is a problem that you must take seriously. We should know that a person's physical quality, ideological and moral character, ideal sentiment and knowledge and ability will all be basically formed in adolescence.
Middle school students who have entered adolescence have gradually matured their body organs and sexual functions, and have the requirements of participating in social activities independently. At this time, the development of mental health becomes more and more important. However, due to the lack of social experience, poor thinking, analysis and judgment, and lack of social ethics knowledge of both sexes, many people are confused, suspicious and distressed because of sexual problems, and even go astray and make stupid things or mistakes that they regret. As teenagers, we should put all our energy into improving physical quality, scientific and cultural quality and ideological and moral quality. The first step to youth is an urgent need for teenagers to protect themselves and grow up healthily.
How to solve these problems? Students should first understand their physical changes and related problems, and know how to correctly understand and treat these physiological changes. Know how to maintain mental health and develop good mental health habits. In terms of morality, we should know which norms to abide by and develop good sexual moral behavior habits. Improve self-protection and self-control ability. Adolescence self-protection must be based on improving one's own quality, resisting external negative influences, distinguishing unhealthy phenomena existing in society, such as sexually transmitted diseases and drug problems, consciously resisting adverse influences in the social environment, and using favorable conditions in the social environment to protect one's healthy growth.
One of the most sensitive topics of adolescent mental health is adolescent sexual psychology. The generation of teenagers' sexual psychology is generally influenced by the natural instinct from sexual development: teenagers are not only very sensitive and pay attention to the changes of their own sexual organs and functions, but also curious and uneasy, which will also produce the desire to explore sexual knowledge, thus promoting the germination and development of sexual consciousness. Two words, normal! However, we live in a vast world, with good people and bad people, good things and bad things, and the relationship between them is very complicated. For us students, we should be good at choosing a favorable social environment, actively participate in various beneficial entertainment activities, especially accept correct information, be alert to and resist the influence of bad social atmosphere, and consciously resist the potential threats of unhealthy books, unhealthy web pages and audio-visual products in society. If you are in doubt, I suggest you consult your parents and teachers, especially there are psychological teachers in our school, not those with mental illness.
