The association between the polar water molecules
The molecules of water can absorb a lot of heat energy. Water has a very high thermal capacity (4.2 J°1C-1 g-1).The hydrogen bonding forms a lattice which does not easily fall apart as the temperature rises.
Compared to molecules of similar size and properties water has a very high melting point and boiling point.
Water is a very, thermally stable medium which helps living organisms resist changes in their environment.
To make water change from a liquid to a vapour requires a lot of energy. Evaporation of water on a the surface of a body cools it down significantly.
