Some of the cooling comes from the air taking away your body heat, as long as the air temperature is less than your skin temperature. However, most of the cooling comes from evaporation of sweat from the surface of the skin.

The movement of air across our skin increases evaporation. Evaporation removes heat from our skin which causes a cool sensation.

Your skin is being continually moisturized by perspiration. Perspiration evaporates, and since evaporation requires heat transfer, your skin temperature decreases.
There are countless of heat traps along the surface of the skin: creases, hair, wrinkles and other concavities. For you to stay cool, that trapped heat has to be removed.
Fans and wind take away adjacent heated perspiration vapor and the cycle starts again.

Our bodies create heat, the air pushed by the fan hits our bodies and pushes the heat away causing you to feel cool.

In the air , cold particles are heavier than the warm ones !
Therefore , when a fan hits them , they travel faster and
you feel only cold air !
Warm particles , being lighter , always go up in the room . . .
That's why we put fan heaters on the floor and the
air conditioning system near the ceiling !!!
