Coffee is not recommended during pregnancy. Coffee is rich in caffeine, and excessive coffee intake by pregnant women has certain effects on the fetus and the health of pregnant women, but there are many studies that show that a small intake of coffee is generally not harmful to the body of pregnant women. Since the caffeine content of different types of coffee varies, it is difficult to calculate the amount of caffeine in your daily life, so you should avoid drinking it as much as possible. If you need to drink it, it is recommended that you drink decaffeinated coffee or strictly limit the amount you drink. The presence of caffeine and other substances that excite the central nervous system in coffee may cause a pregnant woman’s heart rate to increase, blood pressure to rise, and even dizziness, nausea and insomnia in severe cases, which may affect the physical condition of the pregnant woman and indirectly affect the health of the fetus. In addition to coffee, cola, strong tea and other drinks contain caffeine, it is recommended that pregnant women choose to drink plain water or mineral water. During pregnancy, you should also avoid emotional excitement and exertion, and if you are sleepy, you need to use refreshing drinks instead by increasing your sleep time.
