Frequently Asked Questions
How is recommended water intake calculated?
This calculator starts with a baseline of about 33ml of water per kilogram of body weight, then adjusts upward for higher activity levels and hot or humid climates, which increase fluid loss through sweat.
Does coffee or tea count toward water intake?
Yes, in moderation. While caffeine has a mild diuretic effect, the fluid in coffee and tea still contributes meaningfully to overall hydration for most people.
Do I need more water on workout days?
Yes, intense exercise increases fluid loss through sweat. This calculator already factors activity level into your daily recommendation, but very long or intense sessions may require additional water during and after exercise.
