Pregnant women can raise their legs appropriately during pregnancy to help relieve edema, but be careful not to raise them at 90° or higher to avoid affecting the development of the fetus in the womb. Some pregnant women may experience edema in their legs and feet in late pregnancy, which is a normal physiological phenomenon, and they can elevate their legs when they sleep to relieve the edema. In addition, pregnant women can usually raise their legs for sports, which can promote the body’s metabolism and enhance physical fitness. Pregnant women should not raise their legs too high, because raising the legs too high will produce compression on the abdomen, which will lead to pressure on the uterus and cause uterine contractions under external stimulation, which may cause preterm labor or premature birth in serious cases. Therefore, the legs can be raised appropriately during pregnancy, but the angle should not be too large, and do not often sit or stand for a long time, so as not to affect blood circulation.
