The use of electric blankets is usually not recommended during pregnancy, and pregnant women do not need to be particularly anxious if they have already used electric blankets. According to the length of time of use and the height of temperature adjustment, the follow-up measures are mainly divided into the following two kinds: 1. Short-term use: if the pregnant woman has used electric blanket only 1-2 times occasionally, and the temperature adjustment is not particularly high, usually there is no need to be anxious, the electric blanket produces low radiation, and the fetus is in the uterus, there is the abdominal wall and the amniotic fluid protection, usually there will not be any adverse effects such as fetal deformity, and in the future, try to not use the electric blanket, and pay attention to regular obstetric examination; 2. Long-term use: early pregnancy is the sensitive embryonic cell differentiation. Electric blankets, pay attention to regular maternity checks can be; 2, long-term use: early pregnancy is a sensitive period of embryonic cell differentiation, electric blankets produce electromagnetic radiation, if at the same time regulate the temperature is high, prolonged use may affect the normal development of the fetus, it is recommended to strengthen the pregnancy monitoring, 11-14 weeks of pregnancy ultrasound to detect the thickness of the fetal nuchal translucency layer, 15-20 weeks of pregnancy for Down’s syndrome screening, 22-28 weeks of pregnancy to do 4D Ultrasound for macroanalysis, if necessary, can do non-invasive DNA or amniocentesis, the above tests are not found abnormal, you can continue the pregnancy. The radiation emitted by electric blankets in the process of energizing is very low, belonging to the ultra-low-frequency radiation, which usually does not cause damage to the human body, but for pregnant women, infants and other special groups, they should be more cautious, even if the amount of radiation is low, but also try to avoid it. In addition, the electric blanket continued high temperature is not conducive to the normal development of the fetus, but also easy to cause pregnant women dry mouth, sore throat and other symptoms of fire, should pay attention to hydration.
