The National Institute of Medicine recommends about 2.2 liters or about nine cups for women, and 3 liters, about 13 cups for men everyday.
Certain conditions may increase or decrease your individual needs. In general, signs of a well-hydrated body include:
- Pale yellow or colorless urine (Urine is darker first thing in the morning)
- Quenched thirst
- Feeling well
Sometimes you might need more (or less). When you are ill, you need more than a pill. Health conditions such as fever, vomiting, or diarrhea cause your body to lose extra fluids. A large infection or wound on your skin can increase your needs as well. Drink more water or oral re-hydration solutions (Sports Drinks or solutions sold in pharmacies such as Pedialyte) to replace what you have lost. People with heart, liver, kidney, or adrenal diseases may need to limit the amount their intake. |
