Frequently Asked Questions
How much water should I drink daily?
A general guideline is half your body weight in ounces. A 160-lb person should aim for about 80 oz (10 cups). Active people, hot climates, and larger bodies need more.
Does coffee or tea count toward water intake?
Yes, caffeinated beverages do contribute to hydration despite their mild diuretic effect. However, plain water is still the best choice for primary hydration.
How do I know if I am dehydrated?
Signs include dark yellow urine, thirst, dry mouth, fatigue, headache, and dizziness. Aim for pale yellow urine as an indicator of good hydration.
Can I drink too much water?
Yes, overhydration (hyponatremia) is possible but rare. It occurs when you drink excessive amounts quickly, diluting blood sodium. Spread intake throughout the day.
