The general daily water intake recommendations in ounces are:
- Adult men: about 104 to 131 ounces (13 cups to around 3.7 liters) of total fluids per day, including water from all beverages and food
- Adult women: about 72 to 95 ounces (9 cups to around 2.7 liters) of total fluids per day, including water from all sources
- Pregnant women: around 80 ounces (10 cups) per day
- Breastfeeding women: around 104 ounces (13 cups) per day
- Children’s intake varies by age, for example:
- Ages 4-8: about 40 ounces (5 cups)
* Ages 9-13: about 56-64 ounces (7-8 cups)
* Ages 14-18: about 64-88 ounces (8-11 cups)
These amounts are general guidelines and can vary based on factors like activity level, climate, body size, and health status. For example, physically active people or those in hot climates may need more water
. A common simplified rule 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 personal needs
. The traditional "8 glasses of 8 ounces" (64 ounces) per day is a rough estimate and may not suit everyone, but it is a reasonable minimum for many adults
. In summary, a typical adult should aim for roughly 70 to 130 ounces of water daily from all sources, adjusting intake based on individual factors.
