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. A South African group describes the case report of a 20-year soldier who had a 50 km march at around 37 ° C. At the time of the start, the soldier was good dehydrated due to the laboratory values.During the march, he was able to supply all 5 km of liquid supplies which were offered at catering items.Liquid supply and body core temperature were regularly checked and its speed was monitored by GPS.Up to km 40 he drank almost 13 l, almost 4 l more than the other soldiers.During the time he was found 2.24 km before the aim.Despite all medical measures, he died the following day.
This case report clearly shows that too much fluid supply during a physical load can lead to a stress-associated hyponatrigraine encephalopathy with death. The case report is under https://pubmed.ncbi.nlm.nih.gov/25586818/
