Pregnant women should reduce heavy physical labor. If they want to do housework or go to work, they should try to sit down because women's normal posture is mainly supported by ligaments. During pregnancy, the weight of the abdomen is getting bigger and bigger, and it is not enough to rely solely on the support of ligaments. You also need the help of some muscles. Sitting down can reduce the pressure on ligaments and muscles and reduce the low back pain that pregnant women often suffer. It is best for pregnant women to choose a chair with a backrest when sitting, and sit down and lean back. On the one hand, it can avoid bending the body and increase the pressure on the abdomen, on the other hand, it can transfer the gravity of the body to the chair back, so as to get a full rest. When sitting up, you may wish to use a small chair to pad your feet and separate your legs properly so as not to oppress your abdomen. Don't cross your legs, because it will hinder blood circulation and affect fetal development.
Keep your body upright when standing, so that you can contract the abdominal muscles in front as much as possible and lift the front edge of the pelvis, so as not to tilt too much and cause back pain.
