Salt increases intravascular osmolarity, which increases water retention to correct the osmolarity. This is freshman inorganic chemistry. There's plenty of biomedical science behind renal pathophysiology and the link between salt and blood pressure is as close to an if-then statement as there is in medicine. We use all sorts of drugs and methods to play with this central mechanism and can observe the effects in real…
