The amount of water you should drink daily depends on factors such as age, sex, activity level, climate, and whether you are pregnant or breastfeeding. General daily water intake recommendations:

• Adult men (19 and older): about 104 to 131 ounces (13 cups to 15.5 cups) of total fluids per day, including water from all beverages and food

• Adult women (19 and older): about 72 to 95 ounces (9 to 11.5 cups) of total fluids per day

• Pregnant women: around 80 ounces (10 cups)

• Breastfeeding women: up to 104 ounces (13 cups)

• Children’s needs vary by age, from about 32 ounces (4 cups) for toddlers to 64-88 ounces (8-11 cups) for teens

Additional considerations:

• Physically active people or those in hot climates may need more water to replace fluids lost through sweat

• About 20% of daily fluid intake typically comes from food; the rest should come from drinks

• A simple guideline is to drink when thirsty and keep a water bottle handy for regular hydration throughout the day

• Some recommend a weight-based approach: about 0.5 to 1 ounce of water per pound of body weight daily (e.g., a 175-pound person might drink 90-175 ounces)

Summary:

Group| Daily Water Intake (oz)| Cups (8 oz each)
---|---|---
Adult men| 104 - 131| 13 - 16.4
Adult women| 72 - 95| 9 - 11.9
Pregnant women| ~80| 10
Breastfeeding women| ~104| 13
Children (varies by age)| 32 - 88| 4 - 11

These are general guidelines; individual needs vary. Drinking water regularly throughout the day and adjusting for activity and climate is key
