Occasional use of electric blankets in the first month of pregnancy generally does not have a great impact on the growth and development of the fetus, it is recommended to do ultrasound to check the growth and development of the embryo, if the embryo is well developed, the fetal heart, buds can be seen and in line with the corresponding gestational weeks, you can consider continuing the pregnancy. If no fetal heart, buds, first of all need to be regularly rechecked, 9 weeks of pregnancy is still not detected and need to be alert to the possibility of embryonic failure, need to go to the hospital in a timely manner, if necessary, terminate the pregnancy. However, it is not recommended to use electric blankets during pregnancy. Although the electric flow of electric blankets is small, long-term use of electric blankets produces electromagnetic fields and heat that may be potentially dangerous to the fetus at the developmental stage, which may affect the cell division of the fetus. Moreover, the use of electric blankets during pregnancy can easily lead to dehydration and dry skin, which may sometimes induce respiratory diseases and symptoms such as dry mouth and sore throat. During pregnancy, daily attention should be paid to stay away from electromagnetic radiation, in addition to electric blankets, but also try to avoid the regular use of microwave ovens and other household appliances. In addition, it is important to have regular labor and delivery checkups, and to do late screening for malformations, such as Down’s syndrome screening and ultrasound for malformations.
