How Much Water Do You Really Need?
While the "8 glasses a day" rule is easy to remember, individual water needs vary significantly based on:
- Body size: Larger people need more water
- Activity level: Exercise increases fluid loss through sweat
- Climate: Hot/humid weather increases sweating
- Diet: High-salt or high-protein diets require more water
- Health conditions: Fever, diarrhea, diabetes affect needs
- Pregnancy/breastfeeding: Increased demands for fetal development and milk production
