Eating cold foods during menstruation may cause increased menstrual flow or dripping of menstrual flow, as well as low menstrual flow, and may even induce dysmenorrhea. Because the endometrium is peeling off during menstruation, food may cause stagnation of menstrual blood, which may cause dysmenorrhea and may even cause lack of qi and blood, and may produce irregular menstruation. Therefore, you must not eat raw and cold food or even stimulating food during menstruation to avoid certain effects on your body. If you have already eaten, observe if there are any adverse reactions. If not, you do not need to worry excessively, you can drink more brown sugar water, including red bean and black rice porridge, and eat these warm and tonic foods for remedy. If you have not yet eaten, you must be careful not to eat cold food again, so as not to have an impact on the body.
