It is not good to lie in bed at the beginning of pregnancy, if there is a manifestation of pre-eclampsia, appropriate bed rest and activity of the lower limbs, but long-term bed rest is not recommended. The reasons are as follows: 1. Early pregnancy should pay attention to rest, avoid heavy physical labor, prohibit intercourse and tub bath to avoid causing preterm abortion, rather than lying in bed all the time. Clinical evidence-based medical data show that long-term bed rest does not improve the outcome of pregnancy.2. Blood circulation in the lower extremities slows down during long-term bed rest, making it easy to form blood clots, such as deep vein thrombosis in the lower extremities and pulmonary embolism. Therefore, it is recommended to move appropriately in early pregnancy and not to lie in bed all the time.
