Aunt refers to menstruation. Women who eat foods with low temperature such as ice cream during menstruation may cause uterine vasoconstriction causing dysmenorrhea as well as reduced menstrual flow, and may even cause irregular menstruation. During menstruation, women should avoid eating foods with low temperature such as ice cream and cold drinks, because foods with low temperature will stimulate the body and lead to vasoconstriction of the blood vessels of the body, in which contraction of the blood vessels of the uterus will cause menstrual cramps, and the contraction of the blood vessels of the uterus may lead to a decrease in the amount of menstrual flow. If women often eat foods with low temperature during menstruation, it may also lead to the emergence of menstrual irregularities, in which patients may show symptoms such as increased or decreased menstrual flow, irregular menstrual cycles, dysmenorrhea and other symptoms, and in serious cases, it may also affect women’s reproductive function. In addition, eating iced food during menstruation may also cause gastrointestinal discomfort, resulting in abdominal pain and diarrhea. If a woman eats food with too low a temperature during menstruation that causes dysmenorrhea, it is recommended that she go to the hospital for examination and treatment in a timely manner if the symptoms of dysmenorrhea are severe or accompanied by other conditions.
