常見問題
- How is the target estimated?
- It starts from a weight-based estimate — commonly around 30–35 ml per kilogram of body weight — then scales up for higher activity levels.
- Does food and other drink count?
- Yes. A good share of daily fluid comes from food and other beverages, so you rarely need to drink the whole figure as plain water.
- Is this the same for everyone?
- No. Climate, body size, health conditions, and medications all change needs, so treat the number as a general guide rather than a fixed requirement, and follow medical advice if you have a condition that affects fluids.
- Is my weight kept private?
- Yes. The estimate is computed in your browser from the weight and activity level you enter — those values are never uploaded or stored.
