Did you know you can actually over hydrate with deadly results? The story of a teen who died due to water intoxication tonight at 5. Heres info from our experts at the University of South Florida Generally, athletes lose a liter to a liter and a half per hour of exercise in sweat Most athletes WILL be dehydrated after a prolonged event in the heat The only time an athlete can typically be OVERHYDRATED is if they are replacing sweat loses (which has sodium, potassium, magnesium in addition to water) with lots of pure water over a long time If you rehydrate with carbohydrate/electrolyte beverage you will not “overhydrate” Try to maintain hydration before (prehydration), during (hydration), and after (recovery) Prehydration – 500ml cold water or sports drink Hydration – at least 8 oz every 15 min of sports drink (ideal for longer events/practices) or water Recovery – 16 oz per pound of weight loss during activity for rehydration (ideally sports drink and/or chocolate milk) Signs of dehydration and over-hydration? Dehydration Thirst, fatigue, weakness, confusion, light – headed, poor performance, cramping, tired, passing out, dizzy To avoid “overhydration” better titled dilutional hyponatremia, drink sports drinks rather than water when rehydrating during longer events Overhydration – dilutional hyponatremia Weakness, passing out, muscle twitching, seizures, death Eric E.
