常见问题
Is the "8 glasses a day" rule accurate?+
The "8x8 rule" (eight 8-oz glasses) is a reasonable baseline but not scientifically calibrated. Actual needs vary significantly based on body weight, activity level, climate, and diet. This calculator provides a personalized recommendation.
Can you drink too much water?+
Yes. Hyponatremia (water intoxication) occurs when excessive water intake dilutes blood sodium levels. It's rare in normal circumstances but can happen during extreme endurance events. Drink to thirst and follow the calculated recommendation.
