The magnitude of the effect of computer radiation on pregnant women depends mainly on the length of time they are exposed to computers and the period of pregnancy. Pregnant women can use computers appropriately in their daily life, but the duration of use should not be too long. Some pregnant women may experience dizziness and nausea after using computers for a long time, which may be caused by the very low frequency electromagnetic fields of computers. In the first 3 months of pregnancy, it is an important period for embryonic development, when tolerance is low and sensitive, and electromagnetic radiation can easily cause abnormalities in fertilized eggs, so you should try not to touch the computer and stay away from ionizing radiation. In addition, in the 4th-5th months of pregnancy, electromagnetic radiation can also affect the health of the fetus. Therefore, pregnant women should try not to use the computer for a long time during pregnancy, and need to take a break after using it for an hour or so. You can wear regular brands of protective clothing when using computers to reduce the effects of radiation. In addition, it is recommended to avoid toxic and harmful substances during pregnancy and to avoid smoking and alcohol to prevent adverse effects on the fetus.
