Evaporation is the loss of heat that occurs when water is converted into a vapor, such as inadequately dried skin. Conduction is the loss of heat to a cooler surface by direct skin contact, such as when the infant is placed on a cold surface. Convective heat loss occurs when the neonate is exposed to drafts and cool circulating air, such as being placed near an open window or fan.
