The temperature of the air does not change (as I mentioned in my original
note). Your perception of the temperature changes because of the "wind
chill" effect. When you blow it faster it feels cooler, but it is *not*
cooler. Because of the cooling effects of evaporation and perhaps some
other reasons, moving air *feels* cooler than it is to us human beings.
But, unfortunately that has nothing to do with the actual temperature.

In fact one can change the temperature of the air by changing the amount of
time the air is held within the lungs. When air is inhaled it is both warmed
and humidified in our lungs. This amount of heat that can be transferred to
the air is dependent on the amount of time the air is contained within the
lungs.

But there is a limit. Once the air is held in the lungs beyond a certain
point it reaches equilibrium and will not be warmed further.
