blood containing increased levels of aldosterone circulates to the kidneys. In the kidneys aldosterone increases reabsorption of sodium and water so that less is lost in the urine. Aldosterone also stimulates the kidneys to increase secreation of potassium and hydrogen ion into the urine. With increased water reabsorption by the kidneys blood volume increases. As blood volume increases blood pressure increases with salt intake.

The idea of salt being responsible for high blood pressure is archaic. Water and salt actually regulate the blood pressure. (see below)When you get dehydrated and the cells begin losing water, then the body will borrow the water it needs to inject into the cells from other sources - commonly from the blood, since the blood is made up of 94% water and salt.This causes the arteries to constrict due to less volume, and it causes the blood to thicken. Pumping thickened blood through narrower arteries requires extra pressure, and this translates into the higher blood pressure readings.In response to Sweety's answer, she's referring to a part of the body's drought management program that filters and injects “load-free” water into vital cells by the actions of vasopressin and the renin-angiotensin-aldosterone systems—when the body physiology is constantly forced to rely on its drought- management programs.Drinking water and balancing it with adequate amounts of salt will lower the blood pressure and avoid such drought management tactics.Salt has many vital functions. To name just a few -1. Salt is most effective in stabilizing irregular heartbeats and, contrary to the misconception that it causes high blood pressure, it is actually essential for the regulation of blood pressure - in conjunction with water. Naturally the proportions are critical. 2. Salt is vital to the extraction of excess acidity from the cells in the body, particularly the brain cells.3. Salt is vital for balancing the sugar levels in the blood; a needed element in diabetics.4. Salt is vital for the generation of hydroelectric energy in cells in the body. It is used for local power generation at the sites of energy need by the cells.5. Salt is vital to the nerve cells' communication and information processing all the time that the brain cells work, from the moment of conception to death.6. Salt is vital for absorption of food particles through the intestinal tract.7. Salt is vital for the clearance of the lungs of mucus plugs and sticky phlegm, particularly in asthma and cystic fibrosis.8. Salt is vital for clearing up catarrh and congestion of the sinuses.9. Salt is a strong natural antihistamine.10. Salt is essential for the prevention of muscle cramps.11. Salt is vital to prevent excess saliva production to the point that it flows out of the mouth during sleep. Needing to constantly mop up excess saliva indicates salt shortage.12. Salt is absolutely vital to making the structure of bones firm. Osteoporosis, in a major way, is a result of salt and water shortage in the body.13. Salt is vital for sleep regulation. It is a natural hypnotic. 14. Salt is a vitally needed element in the treatment of diabetics.15. Salt on the tongue will stop persistent dry coughs.16. Salt is vital for the prevention of gout and gouty arthritis.17. Salt is vital for maintaining sexuality and libido.18. Salt is vital for preventing varicose veins and spider veins on the legs and thighs.19. Salt is vital to the communication and information processing nerve cells the entire time that the brain cells work - from the moment of conception to death.20. Salt is vital for reducing a double chin. When the body is short of salt, it means the body really is short of water. The salivary glands sense the salt shortage and are obliged to produce more saliva to lubricate the act of chewing and swallowing and also to supply the stomach with water that it needs for breaking down foods. Circulation to the salivary glands increases and the blood vessels become "leaky" in order to supply the glands with water to manufacture saliva. The "leakiness" spills beyond the area of the glands themselves, causing increased bulk under the skin of the chin, the cheeks and into the neck.
