Answer:
The water has a high heat of vaporisation, this means that requires more energy that other solutions to evaporate. Now, water is a basic element that's involved in everything, one of the reason to human lives are possible in Earth is for this.
So, in this high heat vaporisation process, another one is involved and really crucial to our bodies, because when water evaporates, the surface beneath gets cooler, this is called evaporative cooling, and that is one of the most important things that affect organisms, temperature regulation.
