How old is a girl's puberty?

Girls' puberty begins at 10- 12 years old, and most of them last until 17- 18 years old. However, some girls' puberty is quite different and cannot be generalized. As long as the child has secondary sexual characteristics, such as breast enlargement, menstrual cramps, pubic hair and so on. It shows that the child has entered adolescence.

Adolescence is the most rapid and obvious period of personal physical and mental changes. From this period on, children's body, appearance, behavior pattern, self-awareness, communication and emotional characteristics, outlook on life, etc. They are divorced from the characteristics of children and gradually mature, closer to adults.

These rapid changes will make teenagers have mental health problems such as confusion, inferiority, anxiety and even bad behavior. In this period, people's development from children to adults is predictable, but what will happen or what problems will appear in the development process is unpredictable.

Extended data:

Adolescent girls are in the stage of vigorous metabolism, and sweat glands and sebaceous glands secrete more, nourishing the surrounding skin. The wrinkled inner wall of labia majora is easy to accumulate dirt, especially for fatter girls. In addition, in adolescence, due to active ovarian function, vaginal secretions increase, and vulva and vagina are close to anus or urethra, which are easily polluted by urine and feces.

These reasons will cause girls' vulva itching, and also cause secondary infection and folliculitis. Long-term itching stimulation may cause insomnia, haggard, anxiety and high tension. Therefore, perineal hygiene is very important.
