Can't! It is not advisable to swim for three days before and after menstruation! \ x0d \ x0d \ Because women's reproductive organs are very different from men's, the internal genital uterus communicates with the outside world through the vagina and with the abdominal cavity through the fallopian tube. During menstruation, the endometrium falls off, the cervix opens, and menstruation flows out of the vagina. At this time, the endometrium is a wound, rich in blood vessels and a hotbed of bacterial reproduction. When swimming, bacteria in the water have a chance to enter the vagina. There is an annular depression between the vagina and the external opening of the uterus called vaginal vault, in which submerged water can accumulate, which provides conditions for the reproduction of bacteria. If bacterial infection goes retrograde to uterus, fallopian tube and abdominal cavity. In addition, swimming consumes a lot of physical strength, temporarily reduces resistance, and easily causes inflammation of uterus, fallopian tubes and abdominal cavity. \ x0d \ x0d \ In addition, the water temperature in the swimming pool is generally lower than the skin temperature, and the body's resistance during menstruation is low, which is easy to cause a cold when swimming. At the same time, the stimulation of cold water on the skin, especially the abdominal skin, can reflect the contraction of small blood vessels in abdominal organs, especially pelvic organs, and reduce menstrual flow. Not discharging menstrual blood from the uterus during menstruation is not good for your health and may even cause gynecological diseases. \x0d\\x0d\ Some women think that they can still swim during menstruation as long as they are coated with sanitary suppository. In fact, this method is not desirable. Because menstrual blood is a good breeding base for germs, and the uterus during menstruation is open, after the sanitary suppository is soaked in water, germs can easily enter the body through the cotton layer that absorbs menstrual blood, causing reproductive system infection. In addition, because cold water stimulates menstrual swimming, it can also cause menstrual disorder.
