The general daily water intake recommendations for adults are:
- Men: about 125 to 130 ounces (approximately 15.5 cups or 3.7 liters) of total fluids per day, including water from all beverages and food
- Women: about 91 to 95 ounces (approximately 11.5 cups or 2.7 liters) of total fluids per day
These amounts include fluids from all sources, not just plain water. Typically, about 20% of daily fluid intake comes from food, with the rest from drinks
. For children, daily water intake varies by age:
- Ages 4-8: about 40 ounces (5 cups)
- Ages 9-13: 56 to 64 ounces (7 to 8 cups)
- Ages 14-18: 64 to 88 ounces (8 to 11 cups)
Pregnant women should aim for about 80 ounces (10 cups) daily, and breastfeeding women about 104 ounces (13 cups)
. Water needs vary depending on factors such as activity level, climate, age, and health status. Physically active individuals and those in hot climates require more fluids
. The traditional "eight 8-ounce glasses a day" rule is a general guideline but not scientifically precise for everyone
. In summary, a healthy adult man should drink roughly 125-130 ounces, and a woman about 90-95 ounces of fluids daily, adjusting for personal factors and conditions.
