The general daily water intake recommendations in ounces are as follows:
- Men (19 years and older): about 104 to 131 ounces (13 cups to 15.5 cups) of fluids per day.
- Women (19 years and older): about 72 to 95 ounces (9 cups to 11.5 cups) of fluids per day.
- Pregnant women: around 80 to 104 ounces (10 to 13 cups) per day.
- Breastfeeding women: about 104 ounces (13 cups) per day.
- Children’s needs vary by age, for example, 40 ounces (5 cups) for ages 4-8, and up to 88 ounces (11 cups) for ages 14-18
These amounts include all fluids consumed, not just plain water, and about 20% of fluid intake typically comes from food. Individual needs vary depending on factors such as physical activity, climate, health status, and pregnancy or breastfeeding
. A common guideline often cited is to drink eight 8-ounce glasses of water per day (64 ounces), but scientific recommendations suggest this is a rough estimate and not suitable for everyone. Listening to your body’s thirst signals and adjusting intake accordingly is advised
. In summary, a healthy adult man should aim for roughly 104 to 131 ounces of fluids daily, and a healthy adult woman about 72 to 95 ounces, with adjustments for lifestyle and physiological conditions
