Is the blood pressure increase (with increase in sodium intake) temporary, which implies that the body gets used to the increased sodium and blood pressure drops back to some average/normal level after days or weeks of the new intakes?

If yes, why is it that a very common advice from doctors and all kinds of “health information sites” is to cut salt and sodium to manage or reduce high blood pressure? Is the sensitivity to sodium not easy to detect or is it actually more prevalent in the population?
