Can you guys smell the Aroma of Coffee???
Coffee is one of the world’s most beloved beverages. In fact, people across the globe consume close to 19 billion pounds (8.6 billion kg) annually (1).
If you’re a coffee drinker, you’re probably well acquainted with the “coffee buzz” that arrives not long after those first few sips. Even the aroma alone can begin to perk you up.
However, there has been some debate as to whether regular coffee consumption is really good for you — especially in light of its impact on blood pressure and heart health.
This article tells you whether coffee affects your blood pressure — and whether you should consider dialing back your daily java fix.
Science suggests that the physiological effects of drinking coffee can extend beyond a small dose of wakefulness. Research indicates that it may increase blood pressure for a short time after consumption.
A 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).
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.
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).
Based 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.
Summary Research indicates that coffee may increase blood pressure for up to three hours after consumption. However, if you drink it regularly, this effect is diminished.
