What is the term used for the ability of a baby to maintain body temperature?

The term "thermoregulation" specifically refers to the processes that maintain the body's temperature within a certain range, which is vital for ensuring optimal physiological functioning. Newborns, particularly those in a neonatal intensive care setting, have an immature thermoregulatory system, making them particularly vulnerable to temperature fluctuations. Effective thermoregulation is crucial for preventing hypothermia or hyperthermia, both of which can lead to serious complications.

In the context of neonatal care, thermoregulation involves mechanisms such as vasoconstriction, shivering, and the production of heat through metabolic activity, but it is the overall ability to manage body temperature that defines thermoregulation. This ability ensures that the infant can adapt to environmental changes and maintain a stable internal environment, which is essential for their growth and development. Understanding thermoregulation can help healthcare providers implement strategies to keep infants warm, such as using incubators or skin-to-skin contact with caregivers.
