The general daily water intake recommendations vary by age, sex, and life stage, but here are the commonly suggested guidelines in ounces:

• Adult men (19 years and older): about 104 to 131 ounces (13 cups to roughly 16 cups) of total fluids per day, including all beverages and water-containing foods

• Adult women (19 years and older): about 72 to 95 ounces (9 to 12 cups) of total fluids per day

• Pregnant women: approximately 80 ounces (10 cups) per day

• Breastfeeding women: approximately 104 ounces (13 cups) per day

• Children’s recommendations vary by age, for example:
  • Ages 4-8: about 40 ounces (5 cups)
  • Ages 9-13: 56-64 ounces (7-8 cups)
  • Ages 14-18: 64-88 ounces (8-11 cups)

The classic "8 glasses of 8 ounces" rule (64 ounces) is a reasonable baseline but not scientifically precise for everyone, as fluid needs depend on factors like activity level, climate, body size, and health status

. In summary, a typical adult should aim for roughly 72 to 131 ounces of fluids daily, adjusting intake based on personal factors. Drinking water consistently throughout the day and responding to thirst is a practical approach to staying hydrated
