Why does maintaining the vernix layer remain a crucial consideration for newborns delivered via Cesarean section regarding temperature?

Answer

Newborns struggle to maintain their temperature in the first few hours outside of the womb

The benefit of thermoregulation provided by vernix caseosa is universal for all newborns, regardless of the delivery method. Newborn infants have limited capacity to regulate their own body temperature when transitioning from the stable, warm environment of the uterus to the cooler, drier air of the delivery setting. The vernix acts as an insulating layer that aids significantly in maintaining thermal stability during this critical initial period. While babies born vaginally experience lubrication benefits during birth, the thermal assistance provided by the coating is equally vital for those born via Cesarean section who miss the mechanical stress of labor.
