Whether the computer has any effect on the fetus of a pregnant woman is related to the time she uses the computer. Pregnant women who occasionally use the computer for a short period of time generally have no effect on the fetus, but if they use the computer for a long period of time, it may have an effect on the fetus. When using a computer, electromagnetic radiation will occur, and whether electromagnetic radiation harm harms the human body depends on the size of the radiation energy. Electromagnetic radiation from computers is weak, so using computers for a short period of time will generally have no effect on the fetus. However, if a pregnant woman uses a computer for a long time to work or study, it may adversely affect the fetus, and in serious cases, it may lead to miscarriage or fetal malformation. It should be noted that pregnant women should maintain a safe distance and pay attention to the time of use when using computers to reduce the harm caused by electromagnetic radiation.
