The correct way to do postpartum abdominal breathing is to lie on your back and take deep abdominal breaths, inhaling to make the lower abdomen expand and exhaling to make the lower abdominal depression return to its original shape. Postpartum abdominal breathing position for the legs open, knees slightly bent, thumbs open, the remaining four fingers together on the lower abdomen. Inhale deeply when the belly rises, so that the lower abdomen swells and bulges. When you exhale, let your belly contract, so that the lower abdomen is concave and hidden and returns to its original shape. Do not open the chest when breathing, but inhale through the abdominal cavity. When you breathe in, you can feel the abdominal cavity to the upper part of the inner lift, so that you can fully inhale and then fully exhale. Abdominal breathing not only supplies sufficient oxygen to the body but also stimulates peristalsis, smooths airflow and increases lung capacity. Any discomfort during abdominal breathing should be treated promptly.
