It is best not to practice at the beginning of pregnancy, because most pregnant women will have early pregnancy reactions, such as abdominal pain, nausea, vomiting and so on. In the process of practicing, pregnant women may be highly emotionally stressed, affecting the level of hormones in the body, thus causing adverse effects on the health of the pregnant woman and the fetus. Moreover, when practicing, the space inside the car is confined and the air is not circulating, which can easily aggravate the early pregnancy reaction. Therefore, in the early stages of pregnancy, pregnant women should pay attention to rest, avoid strain, try not to stay up late, do not exercise strenuously, do not have intercourse, do not smoke, drink alcohol, avoid eating spicy and stimulating, greasy, fried food, do not eat hot pot, spicy hot, barbecue and other half-baked food, avoid eating raw and cold food, eat more vitamin-rich food. Avoid contact with toxic chemicals and try not to go to places with polluted air. Pay attention to supplementation of folic acid tablets or multivitamin tablets containing folic acid to prevent fetal neural tube malformation.
