Pregnant women should try not to look at their cell phones for more than 3 hours a day and should not use them for more than half an hour each time. In addition, the use of cell phones should be reduced in early pregnancy. Although the radiation of cell phones is small, it is still appropriate to look at them less during pregnancy. If you play with your cell phone for too long in early pregnancy, it is likely to cause harm to the fetus due to radiation and other factors, resulting in poor resistance after birth. In addition, pregnant women play cell phones for a long time, which can lead to high mental tension, eye and cervical discomfort and easy fatigue old. During pregnancy, it is recommended to listen to more music, take appropriate walks, and avoid eating cold and raw food. In addition, it should be noted that sexual intercourse is prohibited in early and late pregnancy to avoid abnormal fetal development.
