Newborns possess a limited capacity to maintain a stable internal body heat. This physiological function, crucial for survival, develops gradually following birth. Initially, infants rely heavily on external sources of warmth to prevent hypothermia. For instance, placing a newborn skin-to-skin with the parent provides essential thermal support.
Effective thermoregulation is vital for conserving energy and ensuring optimal metabolic function in neonates. Inability to maintain a normal body temperature can lead to various complications, including respiratory distress, hypoglycemia, and increased oxygen consumption. Historically, understanding and supporting neonatal thermoregulation has dramatically improved survival rates, particularly for preterm infants.
