Frequent insomnia of pregnant women still has some influence on the fetus. The main reason for insomnia of pregnant women is psychological factors, such as easy anxiety, tension and worry during pregnancy. If this symptom is relatively light, it will not have much effect on the fetus, but if there is excessive anxiety for a long time, poor sleep and insomnia for a long time, it will definitely affect the fetus. Because excessive anxiety and tension will cause psychological stress, increased hormones, and these hormones will more or less have some effect on the placenta and its function. The mind and body of the pregnant woman and the fetus are connected, so it is hoped that the pregnant woman will keep her mood relaxed, her work status and environment good during pregnancy, including handling the relationship between husband and wife, family relationship, etc., so that a healthy baby can be conceived. In addition, severe anxiety conditions can cause other related problems, such as an increased risk of preterm labor or miscarriage. In case of severe anxiety or insomnia, medication is also available in the middle and late stages of pregnancy, such as small doses of Valium to help with sleep, or tranquilizing Chinese medicine to help with sleep and relieve anxiety, but these medications should not be used in the early stages of pregnancy.
