Caffeine and your Blood Pressure
Studies investigating the effect of coffee on blood pressure have yielded varied results. In general, caffeinated coffee causes a short-term spike in blood pressure in people who don’t drink it regularly. This is because caffeine stimulates the heart and blood vessels, according to the Mayo Clinic. In a 12-year study of more than 1,000 people ages, 18 to 45 who had high blood pressure, those who drank four or more cups of coffee per day were four times more likely to have a heart attack or stroke. In contrast, long-term studies have shown that most people develop a tolerance to caffeine over time. Reviews of numerous studies show coffee drinkers were no more likely to develop hypertension than abstainers, and those who already had high blood pressure were no more likely to develop cardiovascular disease.
