Patients in the period bath precautions are as follows: First, must not choose to take a bath when there is a lot of bleeding, choose to take a bath when there is little bleeding. Secondly, do not choose a tub bath but a shower. Because there is blood in the vagina of women during menstruation, blood is the best petri dish for bacteria and the patient’s cervical opening is relaxed, if you take a tub bath, the bacteria, viruses or microorganisms in the dirty water may cause upstream infection, resulting in abdominal pain and other pelvic infections. At the same time, pelvic infection may also lead to adhesions of the fallopian tubes, endometrial adhesions and so on, which will also affect the fertility function of patients. Third, patients must pay attention to keeping warm after bathing, because the resistance of menstruating women’s bodies is relatively low, after bathing must blow dry the hair and wait for the body temperature or local temperature to drop slightly before going out.
