Which factor is a major contributor to the development of hypothermia in the NICU?

Exposure to drafts and low ambient temperature is indeed a major contributor to the development of hypothermia in the NICU. Premature and low-birth-weight infants have limited thermal regulatory abilities and a higher surface area-to-volume ratio, making them particularly susceptible to losing body heat. In a NICU setting, if the environment is not adequately controlled for temperature or if there are drafts coming from doors or windows, it can lead to considerable heat loss in these vulnerable infants.

Maintaining a stable and warm environment is critical, as hypothermia can lead to a range of complications including increased oxygen demand, respiratory distress, and metabolic instability. Thus, keeping the environment warm and free from cold drafts is essential in protecting these infants from hypothermia.
