Fatal case of hyponatremia

Exercise-associated hyponatremic encephalopathy and exertional heatstroke in a soldier: high rates of fluid intake during exercise caused rather than prevented a fatal outcome If athletes are physically burdening over a long time, the recommendation is considered that they should drink so much that the loss of body weight is fully balanced by dehydration.And especially with a load in the heat you should avoid a heat stroke with a lot of drink.
