Define Water as a temperature regulator?

Water plays an important role in the distribution of heat throughout the body and the regulation of body temperature. Heat is generated in the body due to hard work, exposure to heat, fever or merely by the metabolism of energy-yielding nutrients. The most effective route of heat loss from the body is via the evaporation of water as perspiration from the surface of the skin. When perspiration evaporates, the heat is largely drawn from the body. Under normal circumstances, the body is continuously cooled by the evaporation of perspiration lidoin the surface of the skin, known as insensible perspiration.
