This new study was presented today at the annual scientific meeting of the American Society of Hypertension in New York City.Īlthough there has been a lot of recent interest in studying how caffeine may affect the heart and blood pressure, the authors say it's the first time an effect of caffeine has been found on the stiffness of arteries, an indicator of heart function. Researchers say the jury's still out on the effects on caffeine on your heart. But don't put your coffee cup down just yet. Maintaining a balanced diet and healthy lifestyle will likely have more of an impact on blood pressure than coffee consumption.- The caffeine jolt of a java fix may cause a jump in blood pressure - a particular problem in people who already have high blood pressure. Moderate coffee consumption on a regular basis is unlikely to worsen health outcomes in people with high blood pressure. Regular physical activity paired with a diet rich in fruits, vegetables, lean protein and whole grains remain among some of the best ways to promote healthy blood pressure and heart health ( 6).įocusing on these kinds of healthy behaviors is likely a better use of your energy than being overly concerned about your coffee intake. It’s always important to maintain balance in your lifestyle and dietary habits. Keep in mind that eating or drinking too much of anything can lead to negative health effects - coffee is no exception. If you don’t already drink coffee regularly, you may want to wait until your blood pressure is under control before adding this beverage to your routine, as it may increase your blood pressure in the short term. Of course, excessive exposure to caffeine is ill-advised, especially if you already have high blood pressure. Some of the bioactive compounds present in coffee may offer health benefits, including reduced oxidative stress and inflammation ( 2, 4, 5). Should You Avoid Coffee If You Have High Blood Pressure?įor most people, moderate coffee consumption is unlikely to have a significant effect on blood pressure or heart disease risk - even if you have been previously diagnosed with high blood pressure. In fact, coffee contains antioxidants that may promote heart health. Though long-term research is limited, some data indicates that drinking coffee frequently is not associated with increases in blood pressure or heart disease risk. For now, it appears to be perfectly safe and may even be a useful habit to have. Still, more research is needed to better understand how coffee affects human health in the long term. Some researchers theorize that coffee’s health benefits may outweigh any potential negative effects that the caffeine could have on those who drink it regularly ( 2). In fact, coffee may provide some health benefits.įor otherwise healthy people, research indicates that drinking 3–5 cups of coffee daily is linked to a 15% reduction in heart disease risk and a lower risk of premature death ( 3).Ĭoffee contains multiple bioactive compounds that are known to have strong antioxidant effects and may reduce oxidative stress in your body ( 4, 5). Though coffee may increase your blood pressure temporarily right after drinking it, this effect doesn’t seem to extend far beyond the short term.įor people with high blood pressure, current research suggests that daily coffee consumption is unlikely to have a significant impact on blood pressure or overall risk of heart disease ( 2). However, if you drink it regularly, this effect is diminished. Research indicates that coffee may increase blood pressure for up to three hours after consumption. Interestingly, regular coffee consumption is not associated with the same impact on blood pressure - which may be due to the caffeine tolerance that develops when you habitually drink it ( 2).īased on this data, a small to moderate increase in your blood pressure may occur after drinking a cup of coffee - especially if you drink it infrequently. This effect was observed for up to three hours after consumption, and results were similar in people with normal blood pressure at baseline and those with pre-existing high blood pressure. Research indicates that it may increase blood pressure for a short time after consumption.Ī review of 34 studies showed that 200–300 mg of caffeine from coffee - approximately the amount you’d consume in 1.5–2 cups - resulted in an average increase of 8 mm Hg and 6 mm Hg in systolic and diastolic blood pressure, respectively ( 2). Science suggests that the physiological effects of drinking coffee can extend beyond a small dose of wakefulness.
