It is a normal physiological phenomenon for women to take a bath and it will not affect their menstruation. 1, you should take a hot bath, not a cold bath, because cold water stimulation will lead to vasoconstriction, which may cause contraction of the smooth muscle of the uterus, resulting in vasoconstriction in the uterus, reducing the amount of menstruation or even menopause. In addition, it may lead to dysmenorrhea, so take a hot bath. 2, we should pay attention to not sit in the bath, only the shower, through the shower so that the bath water does not enter the vagina, and cause infection of the reproductive tract, so pay special attention, and also recommended after a hot bath quickly towel dry, wear good clothes to avoid getting cold. Taking a shower during menstruation can not only keep the skin locally clean, but also ensure the local cleanliness of the vulva and reduce the possibility of infection.
