If cold symptoms often occur during menstruation, it is mainly because of the relative sensitivity to the decline of estrogen and progesterone, so the body’s resistance decreases, which leads to the occurrence of cold symptoms. Because the estrogen and progesterone in the body will drop to the lowest level during menstruation, due to individual differences, some people are relatively sensitive to estrogen and progesterone, and their self-resistance will drop relatively during menstruation, so they will experience cold symptoms. It is recommended that you can eat vitamin C during the non-menstrual period to increase the body’s resistance, and it is recommended that you do more exercise to enhance your physical fitness and avoid the occurrence of colds. In addition, it is recommended to eat more soy milk, royal jelly, honey, peanut butter, onions, black beans in daily life, which is conducive to improving the body’s resistance.
