Usually, you can take a bath just after your period, but you should pay attention to the water temperature, length and bathing method. During menstruation, a large amount of menstrual blood accumulates in the vaginal area, and at the same time there are sanitary napkins, the ventilation of the lower body area is poor, the mixture of blood and sweat will not only stimulate the skin, but also easy to breed bacteria, causing various inflammatory diseases. At this time, the bath can keep the perineum clean and prevent infection, but in the bath need to pay attention to the following matters: 1, water temperature: in the bath, pay attention to the water temperature not too cold, do not lower the bath water temperature because of the hot weather, so as not to catch cold caused by dysmenorrhea or cold; 2, length: because the body resistance becomes weak, the bath time should not be too long, to avoid blood pressure fluctuations cause dizziness or other discomfort; 3, bath Way: It is better to choose the way of shower and scrubbing. As the opening of the cervix is larger than usual, and the vagina has shed endometrium and menstrual blood, bathing and tubing may cause retrograde infection of pathogenic bacteria, which may lead to vaginitis, cervicitis, pelvic inflammatory disease, adnexitis and other gynecological inflammatory diseases.
