Frequently Asked Questions
Answers to popular questions about daily hydration, sports needs, and health factors.
Q.How much water should I drink per day?
The most accurate daily intake recommendation is based on your body weight: 30–35 ml of water per kilogram of weight. For a 70 kg adult, that is roughly 2,100–2,450 ml (about 8–10 cups). Your specific needs increase with physical activity, hot weather, and certain health conditions.
Q.Is the "8 glasses of water per day" rule accurate?
The "8x8" rule (eight 8-ounce glasses, about 2 liters) is a helpful starting point, but it is not a one-size-fits-all solution. Your individual water needs vary based on body size, metabolism, diet, exercise intensity, and humidity. Our calculator provides a more personalized estimate.
Q.Does coffee or tea count toward my water intake?
Yes, but partially. Caffeinated drinks have a mild diuretic effect. For every cup of coffee or strong tea you drink, it is recommended to add an extra 100–150 ml of plain water to your daily tracker to compensate. Our calculator accounts for this adjustment automatically.
Q.Can I drink too much water?
Yes. Consuming excessive amounts of water in a short period can lead to hyponatremia, a dangerous condition where blood sodium levels become critically low. For most healthy adults, staying under 5–6 liters of water per day is safe. Our calculator caps recommended goals accordingly.
