The importance of maintaining the body temperature of a newborn baby is not a new concept. However, it is difficult to know which temperature to measure – and while the regular measurement of a single temperature tells us how well a baby is able to maintain that temperature, it does not give us any information on energy being used for thermoregulation. Hypothermia in newborns, needs careful management and can affect patient outcomes. Although this issue is serious, thermoregulation in newborns is still an underrated factor in many hospitals.
