CURRENT PUBLIC-HEALTH GUIDANCEHydration is personal.
The CDC notes that getting enough water helps prevent dehydration and supports normal body function. Needs vary with age, activity, climate, pregnancy or breastfeeding, illness, food intake, and medical conditions; there is no single amount that is right for everyone.
Simple daily habits
- Keep safe drinking water available and drink regularly according to thirst and your clinician’s guidance.
- Water in foods, including fruits and vegetables, contributes to fluid intake.
- In hot weather, during activity, or when fever, vomiting, or diarrhea occurs, fluid needs can change.
Follow your care plan
People with kidney, heart, or liver conditions, prescribed fluid limits, or medicines that affect fluid balance may need individualized advice. Ask a qualified clinician rather than forcing a fixed amount.
