If you have just finished your period, it is not recommended to swim immediately. Although there is no menstrual blood coming out of the vagina after menstruation, there may still be some blood left in the cervix, so if you rush into the water, it will easily lead to incomplete menstruation and prolonged periods. As the opening of the uterus is open during menstruation, it may still be open just after menstruation. Bacteria, viruses and other harmful substances in the water can easily enter the vagina and cause upstream infection, which will eventually lead to gynecological diseases such as vaginitis, cervicitis and endometritis, which is not good for health. In addition, just after menstruation, women’s resistance has not yet recovered, if the swimming water is too cold, it is easy to lead to cold attack and cold. Therefore, it is recommended that women swim in the water about 3-5 days after their menstruation is completely clean, so as not to cause unnecessary damage to the body.
