Women should not eat iced things when they have their periods for the following reasons: First, during menstruation, the body’s resistance is relatively weak, including digestive function, absorption function, etc. If women eat iced things during menstruation, it is likely to lead to digestive disorders in women, easily causing nausea, vomiting, anorexia, diarrhea, etc., which may lead to dehydration and life-threatening in serious cases. In addition, eating iced things may also lead to menstrual disorders in women, such as menstrual disorders, or dysmenorrhea and a series of adverse reactions, so you can not eat iced things during menstruation. Secondly, eating ice when menstruating can interfere with women’s endocrine function, especially the endocrine system secretion of estrogen, sex hormones, progesterone, luteinizing hormone, etc. These hormones are very important to the formation and excretion process of menstruation, if eating ice may lead to a decrease in the content of these hormones, thus having a negative impact on menstruation.
