Frequently asked questions
How is the recommended amount calculated?
It starts from a base of 33ml per kg of body weight, then adds extra for higher activity levels and hot/humid climates, or subtracts slightly for cold climates — with a 1.5L minimum floor regardless of inputs.
Is this a precise medical recommendation?
No — it's a general guideline based on common hydration formulas, not personalized medical advice. Individual needs vary with health conditions, pregnancy, and other factors, so consult a doctor for specific concerns.
How is the glass count calculated?
It divides your recommended liters by 250ml (a standard glass size), so the glass count is just a more intuitive way to visualize the same total amount.
