About This Tool
This calculator uses standard medical hydration guidelines (base 35ml per kg of body weight), adjusting dynamically for sweat loss during exercise and hot climates. It automatically subtracts the estimated 20% of water you get from food, giving you a pure "drinking" target.
FAQs
1. Does tea or coffee count towards this target?
Yes. Despite being mild diuretics, tea, coffee, and most other beverages still contribute positively to your overall daily hydration.
2. Why is the target lower than I expected?
Most calculators give you "Total Water", which includes water from food (like fruits and vegetables). This tool specifically calculates how much liquid you need to physically drink.
3. Can I drink too much water?
Yes. Drinking massive amounts of water in a short period can lead to water intoxication (hyponatremia). Spread your intake evenly throughout the day.
