As far as my personal research on
hydration of the body, it really had been the book "The Body's Many
Cries for Water" by Dr. Batmanghelidj, that brought to light the impact
of dehydration on animal physiology, and how a drought management system
is employed by the brain upon initial dehydration of the body from
consumption of food that lacks sufficient water or that arrives into an
insufficiently hydrated body.
However, there is a difference between tap water, spring water and biological water.
