This tool is not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding hydration, exercise, or any medical condition.

Individual variation

Hydration needs vary significantly from person to person based on factors including but not limited to: age, health conditions, medications, climate acclimatization, fitness level, and individual physiology. The estimates provided by this tool are based on general physiological models and may not accurately reflect your personal needs.

Calculation model

Our calculations are based on simplified models derived from general exercise physiology research. They provide rough estimates and should be used as a starting point for understanding hydration balance, not as precise medical guidance.

Listen to your body

The best indicator of hydration is often your own body. Pay attention to signs of thirst, the color of your urine, and how you feel during and after physical activity.

Medical conditions

If you have any medical conditions that affect fluid balance (including but not limited to kidney disease, heart conditions, or conditions requiring fluid restriction), please consult your healthcare provider before using this tool to guide your hydration decisions.
