It is understood that girls in puberty are in the early stage of development, and their physiological organs show various developmental characteristics, especially the internal reproductive system, the most typical of which is the arrival of menarche. During the menstrual period, personal health care is very important. However, due to the lack of necessary guidance in this area and no health awareness, adolescent girls often suffer from menstrual infections, and then gynecological diseases. The reason why girls who like to soak in swimming pools get sick is because they themselves have neglected cleanliness and health measures, causing themselves trouble. Medical experts pointedly said that teenage girls should not stay in water for a long time, such as soaking in swimming pools, hot springs, and bathtubs for a long time.
