                                The average healthy adult needs anywhere from 9 to 15.5 cups of fluid daily, but the idea of 'flushing' your kidneys with a specific number of cups of water is a myth. Your kidneys are highly efficient, self-cleaning organs that require consistent, moderate hydration to function optimally.
