In-Depth Guide & Mathematical Methodology

💧 Clinical Hydration & Osmoregulation

Cognitive & Physical Impact: Dehydration of just 2% body mass impairs concentration, endurance performance, and thermoregulation.

Fluid Sources: ~80% of total fluid intake comes from plain water/beverages, and ~20% from water-rich foods (fruits, vegetables, soups).
