According to Harvard University, a simple oral rehydrating solution is the most effective way to rehydrate yourself. This solution, consisting of salt, sugar and clean water, was found to be cheap and effective when used to treat victims of infectious diarrheal diseases, including cholera, in third world countries. UNICEF’s simple homemade solution contains 5 cups of boiled water, 8 teaspoons of sugar and 1 teaspoon of salt.

In the U.S., electrolyte drinks and sports drinks are the most commonly used methods of rehydration for mild dehydration due to overexertion or diarrhea; however, they are expensive. Intravenous fluids are normally administered in hospitals for severe dehydration.
