In estimating the effect of convection on the cooling of the body, it is lumped in with conduction. Together, they are not generally adequate for cooling.

As one of the basic heat transfer mechanisms, convection involves the transport of energy by means of the motion of the heat transfer medium, in this case the air surrounding the body. The best approach to an estimate of heat loss by this mechanism may be to calculate the heat loss by conduction and to adjust the effective wall thickness used in the conduction calculation to take in to account the fact that air motion will strip away the heated layer surrounding the skin and increase the transfer of heat to the air.
