By water vapour
the process whereby heat moves from one body or substance to another by radiation, conduction, convection, or a combination of these methods. Heat transfer flows from a body with high energy (higher temperature) to lower energy (lower temperature).
The body keeps itself cool by sweating.
sweat is a mechanism to cool the body down. the body creates sweat, so it can cool itself down.
Depending on the scenario, it could be an example of all three, but the most common transfer of energy through heat associated with a heating iron would be conduction. If this is for school and it is possible to have more than one answer, then it would be conduction and radiation.
By water vapour
The three ways are: radiation, conduction, and convection.
The skin works to keep the body cool and the temperature regulated. It does this via four different mechanisms, including evaporation, convection, conduction, and radiation.

The body produces perspiration to cool itself.
There are three ways thermal energy can be transferred: conduction, convection, and radiation.
The human body depends on the evaporation of perspiration to cool itself in hot environments.
sweat is a mechanism to cool the body down. the body creates sweat, so it can cool itself down.
Water is evaporated, an edothermic process; also heat is lost by conduction, radiation, convection.
Mainly sweat (evaporation of), but both radiation and conduction/convection play a part ... especially as the outside temperature goes down. Note that it's the blood circulation that carries heat from the inside of the body to the surface, where the above methods become possible.
sweating is how the body cools itself down.
