Lost fluids must be replaced to decrease the risk of dehydration,regardless of level of fitness.During intense exercise,the body can lose 2 liters of fluid for every hour of exercise.Elevated environmental temperatures also increase the amount of fluid lost through sweating.When athletes drink according to thirst,the risk of overdrinking and so developing exercise-associated hyponatremia is minimized (Noakes,2007).Conversely,exercise can suppress thirst,making it an unreliable signal to replace fluids lost with exercise.
