I guess it is not surprising that there are some who are "salty swearters" - I sort of suspected this as a reason some must resort to extremes like drinking pickle juice.
But this reference from Florida State is the first I have come across that puts the number of "salty sweaters" as high as 10-15%.
This really changes my thinking on dehydration and hyponatremia.
How about you?
