FAQ
How much water should I drink daily?
Needs vary widely based on activity, climate, and health, but a common guideline is about 2.7 liters for women and 3.7 liters for men daily from all beverages and foods. Listen to your thirst and check your urine color—it should be pale yellow.
Is tap water safe to drink?
In most developed countries, municipal tap water is rigorously tested and safe. If concerned, you can use a certified filter or let it sit in an open pitcher to allow chlorine to dissipate.
Can you drink too much water?
Yes, though rare, it is possible to drink excessive amounts in a short time, leading to a dangerous condition called hyponatremia (low blood sodium). This is most common in endurance athletes who drink large volumes without replacing electrolytes.
