It is best not to drink cola during menstruation because the body’s resistance is relatively low during menstruation and the immune system is also low. Some people also suffer from insomnia or emotional instability due to changes in hormone levels during menstruation, and drinking cola is likely to aggravate insomnia and emotional instability. In addition, most colas are refrigerated. If you drink refrigerated colas, it will not only aggravate the symptoms mentioned above, but also cause the possibility of menstrual cramps. It is recommended to drink less carbonated drinks in daily life, as this is not good for your health. In addition to keeping warm and taking proper rest during menstruation, it is also recommended to soak your feet in hot water every day to improve local blood circulation and reduce the uncomfortable feeling in the lower abdomen caused by menstruation.
