Dr. Myers warns, however, that giving oral electrolyte replacement drinks, such as Gatorade, alone might damage the patient. These drinks are so low in sodium and so high in water the dilutional imbalance may be increased. Only a blood test confirms hyponatremia beyond doubt. More severe symptoms of hyponatremia include a patient who is disoriented, irritable, and combative, which gives the problem the more common name of water intoxication. Untreated, the ultimate result will be seizures, coma, and death.
Prevention is a matter of being sensible, which is so often the case.
Drink lots, yes, but eat salty foods regularly while exercising in heat. Nothing's wrong with the electrolyte drinks, but don't forget to eat as well.
