If you think you’re beating the bad effects of cigarettes because you don’t smoke regularly, but still bum one now and then on a night out—you’re kidding yourself! Every puff you take increases your potential for arterial damage. A University of Georgia study found that sporadic smokers who smoked two cigarettes after two days of not smoking were 36 percent less responsive to blood flow changes than nonsmokers. After four cigarettes the arterial response was even worse. Impaired arterial response is the first step to heart disease. Cigarette smokers also have more build up of fatty deposits in their arteries. In fact, the Surgeon General has declared smoking “the leading preventable cause of disease and deaths in the United States.” Secondhand smoke will cause these same effects, so try to avoid it if possible. Smoking also decreases you HDL (good) cholesterol. And don’t forget—it’s bad for your lungs, too!
