How is Daily Water Intake Calculated?
Hydration requirements are calculated dynamically using standard metabolic formulas:
1. Base Intake:
35 ml of water per 1 kg of body weight.
2. Activity Adjustment:
Adds water to compensate for sweat loss (Light: +350 ml, Moderate: +700 ml, Heavy: +1000 ml).
3. Climate Factor:
Adds 350 ml in hot conditions, and subtracts 200 ml in cold environments.
