When considering thermoregulation in the newborn, the loss of heat to moving air at the skin surface is called?

The loss of heat to moving air at the skin surface is known as convection. This process occurs when warm air surrounding the body is replaced by cooler air, leading to heat dissipation. In newborns, whose ability to regulate body temperature is not fully developed, convection is particularly significant. For example, if a baby is in a drafty room, the movement of air around the baby can enhance heat loss from their body, making them more susceptible to hypothermia.

In contrast to other mechanisms of heat loss, such as conduction, which involves direct contact with a cooler surface, radiation, which entails the transfer of heat to surrounding objects through electromagnetic waves, and evaporation, which happens when moisture on the skin is converted to vapor (often associated with drying after bathing), convection specifically focuses on how moving air facilitates heat loss from the body. Understanding this mechanism is crucial in nursing practice to take appropriate measures to maintain a newborn's thermal stability.
