“Hydrating is important when you have a cold and are losing fluids, especially when you have a fever,” explains Dr. Dugoua. But to achieve proper hydration the human body requires electrolytes, which balance out our blood chemistry. “Coconut water is a good source of electrolytes,” says Dr. Dugoua, who notes that salt, bananas and electrolyte replacement drinks used in sports also replenish our electrolyte reserves.
