. For pregnant women, the recommendation increases to about 10 cups (2.4 liters), and for breastfeeding women, up to 13 cups (3.1 liters) daily
. Since water needs depend on many factors, including exercise, temperature, and health conditions, women who are more active or live in hot climates may need more fluids
