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.
