Three Cases of Severe Hyponatremia During a River Run in Grand Canyon National Park An American group has described three cases of hyponatremia at River Rafting. Three women have fed too much liquid because they meant to suffer dehydration in the longer stress.All three women had to be hospitalized and intensive care. In contrast to the stress-associated hyponatremia, there were no physical stresses here and yet there was a hyponatremia.
This description shows nice that too much fluid supply can be very dangerous. The case description can be found under https://pubmed.ncbi.nlm.nih.gov/25736400/
