Introduction
Water is one of the most essential elements for survival, yet many people do not drink enough of it daily. Dehydration occurs when your body loses more fluids than it takes in, affecting normal body functions.
The problem is — most people don’t recognize dehydration early.
By the time you feel extremely thirsty, your body is already mildly dehydrated.
