The baby's first cry is the most beautiful sound for the mother
For a mother who is suffering in the delivery bed, what she most wants to hear is the loud cry of her baby after delivery. People use "croaking to the ground" to describe the birth of a child. This phenomenon has become common in everyone's impression. However, have you ever thought about why babies cry as soon as they are born?
It is not that we take it for granted that "crying is because of the pain and fear of the baby leaving the mother's body." Crying at birth is actually a physiological activity. Before the baby is born, the lungs are a collection of solid tissue without air. The thorax is still only in a state of contraction, and the chest cavity is also very small. After the baby breaks out of the mother's body and arrives, it no longer shrinks into a ball. The chest will suddenly stretch out, the chest cavity will immediately expand, the lungs will open, and the baby will take in the first breath of air. The subsequent inhalation action forces the air in the lungs to be expelled, and the rushing air opens the vocal cords, causing the vocal cords to vibrate and produce a "howl" similar to crying. Crying is a difficult and non-conscious action that requires the use of more than 80% of the main functional organs of the body. Therefore, crying at birth is like a computer starting a self-test program. The baby uses this shocking way to tell the world Declare loudly: "I am here in perfect health!"
