Strategies to prevent heart disease

1. Don't smoke or use tobacco

One of the best things you can do for your heart is to stop smoking or using smokeless tobacco. Even if you're not a smoker, be sure to avoid secondhand smoke.

Chemicals in tobacco can damage your heart and blood vessels. Cigarette smoke reduces the oxygen in your blood, which increases your blood pressure and heart rate because your heart has to work harder to supply enough oxygen to your body and brain.

There's good news though. Your risk of heart disease starts to drop in as little as a day after quitting. After a year without cigarettes, your risk of heart disease drops to about half that of a smoker. No matter how long or how much you smoked, you'll start reaping rewards as soon as you quit.
