Body weight
Air temperature
Air currents in room or incubator
Maturity of neonate’s skin
Evaporation – heat transfer by energy-carrying watter from the skin and respiratory
tract to a drier environment
Affected by
Maturity of neonate’s skin
Wet skin (newly born neonate, prior to drying off)
Radiation – net rate of heat loss in the form of electromagnetic waves between the
body and environmental surfaces not in contact with the body
Dependent on temperature differences between the body and solid objects facing
it.
Radiant heat loss factors
Skin temperature
Exposed surface area
Distance and angles to irradiated objects (e.g. incubator walls, nearby
windows)
NB
Radiant heat loss is independent of air temperature
Cold stress is possible if surrounding walls or windows are sufficiently cold
