How Hydration Calculation Works - Medical Methodology

Our Hydration Calculation System uses WHO-verified medical formulas to provide accurate water intake assessments and health optimization insights. Here's the complete technical methodology:

Core Hydration Formula: Base Water = 35ml × body weight (kg). This calculates minimum daily water requirements for basic bodily functions and metabolism support.

Exercise Adjustment: Additional water = 350-500ml per hour of moderate exercise, 500-700ml per hour of intense exercise. This compensates for sweat loss and maintains performance.

Climate Factors: Normal climate = ×1.0, Hot/Humid = ×1.2, Very Hot/Dry = ×1.4, Cold/Dry = ×1.1. These multipliers adjust for environmental water loss.

Special Conditions: Pregnancy = +300ml daily, Breastfeeding = +700ml daily, Illness/Fever = +500ml daily, Elderly (65+) = adjusted for reduced kidney function.

AI Accuracy Enhancement: Our algorithms incorporate medical research data across different populations, activity levels, and health conditions to provide context-aware hydration recommendations.
