For optimal hydration, drinking water is best served at temperatures between 50 and 72 degrees Fahrenheit according to Prevention. Cold water is able to pass through the stomach much easier; thus, allowing the intestines to absorb more quickly. As a result, cold water is more effective at rehydration.
Staying hydrated by drinking enough water is crucial to one's health. According to the Institute of Medicine, men should drink an average of 13 cups of water in a day, and women should drink an average of 9 cups of water in a day in order to stay hydrated and healthy. Keep in mind that consuming fruits, vegetables and other foods can help an individual meet their fluid needs.
