because in our bodies we have thousands of chemical reactions going on every second. when you tell your toes to wiggle, that signal is traveling from your brain to your toes by a chemical reaction that is very dependent on water being in your cells. Water is the solvent of life because without it nature can not perform the chemical reactions needed to maintain life.
