The general daily water intake recommendations in ounces are:
- Men (19 years and older): about 104 to 131 ounces per day
- Women (19 years and older): about 72 to 95 ounces per day
- Pregnant women: around 80 ounces per day
- Breastfeeding women: around 104 ounces per day
- Children vary by age, for example, 40 ounces for ages 4-8, 56-64 ounces for ages 9-13, and 64-88 ounces for ages 14-18
These amounts include total fluids from all beverages and water-rich foods. The common "8 glasses of 8 ounces" rule (64 ounces) is a reasonable baseline but may not suit everyone, as individual needs vary based on factors like body size, activity level, climate, and health status
. A practical guideline is to drink about 0.5 to 1 ounce of water per pound of body weight daily. For example, a 175-pound person might aim for 90 to 175 ounces, adjusting for exercise and environment
. In summary, most adults should aim for roughly 72-131 ounces of water daily, adjusting intake for personal factors and thirst signals.
