A healthy adult woman should aim to drink about 9 to 11.5 cups (approximately 2.1 to 2.7 liters) of water per day from all beverages and foods combined. This includes water, other drinks like tea or milk, and water content in food

. Key points on daily water intake for women:

• The U.S. National Academies of Sciences recommends about 9 cups (72 ounces or 2.1 liters) of fluids daily for women

• Harvard Health and Mayo Clinic suggest around 11.5 cups (92 ounces or 2.7 liters) daily for women, including fluids from all sources

• The NHS and Better Health Channel suggest aiming for 6 to 8 cups (about 1.5 to 2 liters) of fluid daily, emphasizing water and low-calorie drinks

• Pregnant women should increase intake to about 10 cups (80 ounces), and breastfeeding women to about 12 to 13 cups (96 to 104 ounces)

Factors that influence how much water a woman should drink include:

• Activity level: More water is needed with exercise or sweating.
• Climate: Hot or humid environments increase water needs.
• Health status: Illness, medications, or conditions like diabetes may require more fluids.
• Diet: High salt, spicy foods, or caffeine intake can increase water requirements

A practical guideline is to drink enough so that urine is light yellow, and to adjust intake based on thirst, activity, and environmental conditions

. In summary, about 9 to 11.5 cups (2.1 to 2.7 liters) of fluids daily is recommended for most women, with adjustments for pregnancy, breastfeeding, and lifestyle factors.
