Daily Water Intake: The Number of Water Bottles You Need
Recommended Daily Water Intake: A Guide for Healthy Hydration
Staying hydrated is essential for maintaining overall health and reducing the risk of chronic diseases. Authoritative sources like the National Academies of Sciences, Harvard Health Publishing, Mayo Clinic, and Cedars Sinai have provided guidelines on the recommended daily water intake for various populations.
For healthy adults, the general daily water intake falls around:
- Men: About 3.7 liters (around 13 cups or 125 ounces) per day
- Women: About 2.7 liters (around 9 cups or 91 ounces) per day
Pregnant and breastfeeding women require slightly more water:
- Pregnant women: Approximately 3.0 liters (about 10 cups or 80 ounces) per day
- Breastfeeding women: Up to 3.9 liters (about 13 cups or 104 ounces) per day
These figures include water obtained from all beverages and food combined but emphasize drinking water specifically to maintain proper hydration and reduce the risk for diseases linked to chronic dehydration such as kidney stones and urinary tract infections.
Individual needs may vary based on factors such as age, body weight, climate, physical activity, and health status. A common practical recommendation is to drink roughly half your body weight in ounces of water daily. For example, a 150-lb person should aim for about 75 ounces. Another approach estimates 1 milliliter of water per calorie consumed, approximating about 2-3 liters daily for most adults depending on diet.
Staying consistently well-hydrated supports kidney function, helps prevent bladder infections, constipation, and may aid metabolic health. Drinking adequate water daily is advised as part of a healthy lifestyle.
| Population | Approximate Intake Per Day | |-------------------|------------------------------------------------| | Adult men | 3.7 liters (125 oz, 13 cups) | | Adult women | 2.7 liters (91 oz, 9 cups) | | Pregnant women | 3.0 liters (80 oz, 10 cups) | | Breastfeeding women | 3.9 liters (104 oz, 13 cups) | | Children (varies by age) | 32 oz (1-3 yrs) up to 88 oz (14-18 yrs) |
These values align with recommendations from the National Academies and health institutions like Harvard and Mayo Clinic known for evidence-based guidance.
The National Academies of Sciences have also released a report setting dietary intake levels for water, salt, and potassium to maintain health and reduce chronic disease risk. High salt intake can contribute to the development of high blood pressure and chronic diseases. Additionally, the report emphasizes the role of adequate water intake in maintaining overall health and reducing chronic disease risk.
However, it's important to note that excessive water intake can lead to water intoxication, a potentially life-threatening condition. The Cedars Sinai article "Superhydration: How Much Water Is Too Much?" discusses these potential risks, particularly on kidney function.

Science plays a crucial role in understanding the importance of water intake for health-and-wellness, with institutions like the National Academies of Sciences, Mayo Clinic, and Harvard Health Publishing providing recommendations for daily water intake. These recommendations often emphasize the significance of proper hydration in nutrition, particularly in reducing the risk of chronic diseases.
Adequate water intake, along with a balanced diet, can support kidney function, prevent bladder infections, and contribute to metabolic health. As a part of this health-and-wellness regimen, nutritionists often advise people to consume the recommended daily water intake as suggested by these authoritative sources.
