You are probably mistaken, in that I very much doubt that there is a simple relationship between salt intake, perspiration and sodium levels in cells/bloodstream.

However, when last I looked - some time ago, so I may be out of date - a high salt intake tended to exacerbate hypertension, but not cause it. In other words, if your blood pressure is high you should cut down on the salt. If it isn't, your pickles etc. are probably fine.
