Frequently Asked Questions

How much water should I drink per day?

Individual needs vary based on body weight, activity, climate, and diet. General guidance is 8 cups (2 liters) for women and 10 cups (2.5 liters) for men — but athletes, people in hot climates, and larger individuals need more. Hydro Coach calculates a personalized amount. A practical indicator: your urine should be pale yellow throughout the day.

Does coffee and tea count toward daily water intake?

Yes. Despite old advice suggesting caffeine is dehydrating, research shows caffeinated beverages contribute to daily fluid intake. Coffee, tea, juice, and even water content in food all count. Alcohol is the exception — it causes net dehydration.

Why am I not thirsty even when dehydrated?

Thirst is an unreliable dehydration indicator — it typically isn't activated until you're already 1-2% dehydrated, which already impairs performance. Using a water reminder app provides a schedule-based approach that doesn't rely on feeling thirsty.
