Menstruation is a normal physiological cycle of women and a sign of women's maturity. During menstruation, due to the invasion of menstrual blood, whether lotion can be used is a concern of most women. So can I use female care liquid during menstruation? During menstrual period, the endometrium falls off and bleeds, forming wounds, pelvic congestion, and the neurohumors of the whole body have changed significantly. At this time, the human body's resistance is reduced, the acidic environment of vagina is destroyed, the cervix is slightly open and vulnerable to germs, the defense function of reproductive organs is weakened, and the chance of infection is obviously increased. Generally, women's immunity and resistance are the worst during menstrual period, and the antibacterial ability of vagina will also decrease. Therefore, it is best not to use lotion indiscriminately during menstruation to avoid the adverse consequences of vaginal infection. It is very important for every adolescent girl to do menstrual hygiene well. During menstruation, due to the decline of female immunity, in addition to not using nursing liquid, we should also pay attention to the following points: 1. Change sanitary napkins frequently during menstruation. Especially in summer, humidity easily breeds bacteria. In addition, female friends must take good care of sanitary napkins, don't let sanitary napkins get wet or polluted, and avoid vaginal medication and sitz bath. Avoid washing genitals with bath liquid or washing genitals repeatedly with warm water when taking a bath. 2, keep the vulva clean, scrub the vulva with warm water every night, not bath or sitz bath, preferably shower, sanitary napkins and paper should be soft and clean, breathable, change underwear frequently, and reduce the stimulation of blood stains on the vulva and inner thighs. Wipe from front to back after defecation to avoid bringing dirt into the vagina, causing vaginitis and even pelvic inflammatory disease. 3. No sex. During menstrual period, the endometrium exfoliates and bleeds, there is a wound in the uterine cavity, the vaginal pH changes, and the defense function decreases. If you have sex, it is easy to bring bacteria in and cause genital inflammation. 4. Excessive emotional fluctuation and tension will cause dysfunction between the central nervous system, hypothalamus and pituitary gland, thus affecting the secretion of gonadal hormones and causing irregular menstruation. At the same time, heavy physical labor and strenuous exercise should be avoided during menstruation. Excessive fatigue will make the pelvic cavity hypercongested, causing menorrhagia, prolonged menstrual period, abdominal pain, backache and backache.
