Why do you get cold when you get out of the shower?
The answer is evaporation.
When you step off the bathmat, the water clinging to your skin starts to evaporate.
But to change into a gas, that water needs help—namely, it needs heat energy.
It acquires that energy by sapping heat from your surroundings..
What feels colder humid or dry?

Why do you feel cold when getting out of a swimming pool?
The body uses two main systems to cool down. One is that it sweats; body heat transfers to the sweat (or any water on the body) and the heat is removed from the body when the sweat is wiped away or evaporates.
