Frequently Asked Questions
How much water should I drink per day?
A common guideline is 35ml per kg of body weight (about half your body weight in ounces). However, this varies with exercise, climate, and individual factors. The calculator adjusts for activity level and climate.
Does coffee count toward water intake?
Yes. While caffeine has a mild diuretic effect, the water in coffee and tea still contributes to your daily hydration. However, sugary drinks and alcohol are not ideal hydration sources.
Can you drink too much water?
Yes, though it is rare. Overhydration (hyponatremia) can occur when you drink excessive amounts in a short time, diluting blood sodium levels. Spread your intake throughout the day.
