Control Blood Pressure.

Say No to Smoking, Excessive Drinking
Another way to improve your overall cardiovascular health is to quit smoking and drinking a lot of alcohol.
While drinking in moderation doesn't seem to have much of an impact on your heart, having more than three drinks a day may contribute to high blood pressure. Alcohol has been shown to raise blood pressure by interfering with the flow of blood to and from the heart. When alcohol courses through your bloodstream, it pushes blood rich in nutrients away from your heart.
Studies have shown that it is much more difficult to control blood pressure if you drink heavily. Conversely, a reduction in alcohol consumption can help lower blood pressure.
Smoking also takes a heavy toll on the heart. According to the American Lung Association, over 400,000 Americans die of smoking-related illnesses each year. This figure includes those affected by secondhand smoke and babies born prematurely due to prenatal, maternal smoking.
Nicotine, one of thousands of chemicals found in cigarettes, causes the blood vessels to constrict. This narrowing of the vessels increases blood pressure.
Nicotine is an extremely addictive chemical. Studies show that nicotine activates the circuits in the brain that regulate pleasurable feelings. It does this by increasing the levels of a chemical found in our brains called dopamine. The U.S. Surgeon General warns that nicotine addiction is similar to heroine and morphine addiction. In fact, when smokers inhale, the nicotine reaches the brain faster than drugs that enter the body intravenously.
