People with healthy blood pressureless than 120/80have about half the lifetime risk of stroke as those with high blood pressure, or hypertension. “High blood pressure damages blood vessels throughout the body, making them more susceptible to developing clots,” says Lewis Morgenstern, MD, director of the University of Michigan Stroke Program.
In a study of more than 47,000 men and women in Finland, moderate and high levels of physical activity were associated with lower stroke risk. Exercise helps reduce blood pressure by making the heart stronger. And the stronger the heart, the less effort it takes to pump blood around the bodyso the lower the blood pressure. Physical activity also can help decrease the risk of developing diabetes and control cholesterol levels, both of which up your chances of a stroke.
Experts arent clear on why alcohol raises blood pressure and increases stroke risk, but research from the University of Cincinnati has shown that having more than two drinks a day is associated with subarachnoid hemorrhage, a particularly deadly type of stroke caused by the rupture of a blood vessel on the surface of the brain; it tends to strike premenopausal women.
Gaining even 22 pounds after the age of 18 is associated with increased risk of stroke.
Diets high in saturated fat and cholesterol can raise blood-cholesterol levels.
Stroke risk decreases significantly two years after quitting and is at the level of nonsmokers by five years, research shows. In fact, recent data from the Womens Health Study showed that women who smoke a pack a day are at increased risk of hypertension. Whats more, the nicotine and carbon monoxide damage the cardiovascular system, leading to a higher risk of stroke.
