- Health Status: Fever, vomiting, or diarrhea increase requirements
- Pregnancy/Breastfeeding: Additional fluid needs

Hydration Sources
While water is the best source of hydration, you can also get fluids from herbal teas, milk, fruits, and vegetables. Limit caffeinated and alcoholic beverages as they can have diuretic effects.
