Does smoking cigarettes affect your blood pressure?Why or why not?
Absolutely it does, and in a negative fashion. Because the chemicals and toxins in cigarette smoke are absorbed through the lungs, they travel through the bloodstream and inhibit the delivery of oxygen to your cells in three ways: 1) it makes your lungs work harder to intake less oxygen, which automatically raises both your pulse and blood pressure; 2) it damages the future ability of the lungs to absorb oxygen at all, that is, it diminishes their capacity on a continual basis, increasing your blood pressure for the same reason as #1, and 3) the nicotine, cyanide, formaldehyde and other harmful contents of cigarette smoke serve as both stimulants (which raise blood pressure) and toxins (which damage cells and tissue and make blood delivery more difficult).
One study says that smoking decreases blood pressure because smoking causes anorexia and person who smokes eat less so his or her weight decreases, so the blood pressure decreases.
Smoking injures blood vessel walls and speeds up the process of hardening of the arteries so even though it does not cause high blood pressure, smoking is bad for anyone, especially those with high blood pressure.
