Touching cold water during menstruation may cause women to suffer from menstrual cramps, low menstrual flow and dark menstruation. If you touch cold water during menstruation, it may cause contraction of the uterine muscles, which may affect the normal discharge of menstruation, resulting in a sudden decrease in menstrual flow and darkening of menstruation. When the menstrual blood in the uterus cannot be discharged normally and collects in the uterus, it may lead to painful menstruation. During menstruation, women’s immunity is low and their ability to fight diseases is poor, so touching cold water may also lead to colds. It is recommended that women should not touch cold water during menstruation, including eating cold and raw food, which may also lead to dysmenorrhea, low menstrual flow and black menstrual color. During menstruation, you should pay attention to keep warm, you should be using warm water and eat warm food.
