FAQ
Is 8 glasses a day enough?
The "8 glasses" rule is a good starting point, but individual needs vary based on weight, activity, and climate. Use our calculator for a personalized recommendation.
Can I drink too much water?
Yes, but it's rare. Drinking excessive amounts (several gallons) in a short time can be dangerous. Stick to your calculated amount and spread it throughout the day.
Does coffee count toward water intake?
Yes! While caffeine has a mild diuretic effect, coffee and tea still contribute to your daily fluid intake. However, plain water is always best.
