The first menstruation is called menarche. Some girls come early and some girls come late. Time is mainly related to nutrition, physique and environment. A recent survey in China shows that the average age of menarche of female students is about 13 years old, the earliest age can be about 9- 10 years old, and the latest age can be about 18- 19 years old. Under normal circumstances, the menstrual cycle is generally within 22-32 days, and most of them are around 28 days. The normal menstrual duration is usually 3-7 days, but most of them are 4-5 days. It's normal for menstruation to be irregular, and it will be fine after one year. Don't worry about this problem. Because primary and middle school students in our country ignore adolescent health education, many mothers don't know much about adolescent health knowledge, and girls often panic about the sudden menarche, which causes strong psychological conflicts and affects their study and life. So what do we think about menstruation?
It is normal to have some emotional changes during menstruation, because menstruation will cause changes in secretion in the body. Because the endocrine of many girls is not perfect, the secretion of estrogen and progesterone in the body is unbalanced, which is often accompanied by periodic emotional changes during menstruation, such as irritability, tension, anxiety and depression. Some are accompanied by headache, low back pain, abdominal distension, lethargy, breast pain and other mild physical discomfort reactions, so keep a good mood and don't lose your temper easily, otherwise it may lead to abnormal menstruation, such as less menstrual flow, dysmenorrhea, amenorrhea and so on. This will affect our health. You'd better go out and listen to music when you are upset.
Psychologists call 1-2 years after menarche "dangerous age". That is to say, the maturity of sexual function awakened girls' sexual consciousness, began to sprout interest in sex and sexual knowledge, began to pay attention to the opposite sex, and longed to communicate with the opposite sex. These are actually normal psychological reactions in adolescence, and there is no need to blame yourself for it, but we should also correctly understand this psychological demand, otherwise we may take some detours because of this ignorant sexual consciousness, which will affect our study and life. Due to physiological changes such as decreased brain excitability, pelvic hemorrhage and cervical opening during menstruation, the body's resistance can be reduced, and it is easy to get infected with diseases, which will affect health and future fertility. Therefore, girls should pay attention to menstrual hygiene. Mainly from the following aspects: (1) You can study normally during menstruation, but you must avoid physical and mental overwork; You can go to physical education class as usual during your period, but don't do strenuous exercise.
(2) pay attention to cold and warmth. Because cold stimulation may cause excessive contraction of uterine and pelvic blood vessels, leading to dysmenorrhea or menstrual disorder. Therefore, it is best not to eat cold drinks during menstruation, do not wash clothes with cold water, do not take a cold bath, and take an umbrella in rainy days to avoid getting wet. (3) diet. It is best not to eat spicy food during menstruation.
(4) keep healthy. Because blood is the best culture medium for bacteria, girls must clean their vulva once a day during menstruation, but don't take a bath to avoid dirty water entering the vagina and causing infection. Take a shower when you take a shower. No swimming during menstruation. Sanitary napkins should be soft, clean, disinfected and absorbent, and sanitary napkins should be changed frequently.
In short, treat menstrual phenomena calmly and happily, pay attention to menstrual hygiene, and physical and psychological discomfort rarely occurs.
