How accurate is this calculator?

This calculator uses established formulas and factors. Individual needs may vary by ±10-20%. Monitor your body's signals and adjust accordingly.

Can I drink too much water?

Yes, overhydration (hyponatremia) is possible but rare in healthy individuals. Don't exceed 1 liter per hour or ignore overhydration warning signs.

Do other beverages count?

Yes, but water is best. Coffee, tea, and milk contribute to hydration. Limit sugary drinks and alcohol as they can increase fluid needs.

What about water-rich foods?

About 20% of fluid intake comes from food. Fruits, vegetables, and soups contribute significantly to hydration.

When should I drink more?

Increase intake during illness (fever, vomiting), hot weather, high altitude, pregnancy, breastfeeding, and before/during/after exercise.

What if I have kidney problems?

Consult your healthcare provider. Kidney disease may require fluid restrictions or specific hydration protocols.
