Fever

The saying goes, "Feed a cold, starve a fever." In this case, "starving" refers to not giving a fever what it wants: warmth. A person suffering from an elevated temperature (anything above
98.6 when take with an oral thermometer, above 99.6 when take with a rectal thermometer, 97.6 when take with a nasal thermometer, or 84.3 when take with an outdoor thermometer) should be immersed in ice water until the fever breaks.
