Electrolytes are salts that are naturally part of body fluids. When an athlete sweats, electrolytes are lost through the sweat. If electrolytes are lost too quickly, the body does not have the ability to restore them as rapidly as they were lost. Sports drinks contain electrolytes such as chloride, sodium, and potassium to help replenish what was lost through sweat. Introducing electrolytes back into the body helps keep dehydration from occurring.
