Question
A mother noticed her newborn’s body temperature was abnormally high during breastfeeding, which had never occurred before. She wants to know the possible causes of a newborn’s fever.
Answer
The causes of a newborn’s fever are varied, primarily due to the underdeveloped thermoregulatory center and incomplete development of sweat gland tissues during the neonatal period, leading to inadequate heat production and dissipation functions and poor regulation capabilities. Additionally, newborns have relatively thin subcutaneous fat and a larger surface area, making them susceptible to various factors that can cause fever. If the situation does not improve, it is recommended to visit a professional hospital for further examination.
