Is coffee bad for blood pressure?

In the short term, caffeine slightly raises blood pressure and heart rate. With regular consumption, the body builds tolerance. Long-term studies show no increased cardiovascular risk with moderate consumption. If you have high blood pressure, consult your doctor.

Why that is

Coffee and blood pressure—this topic unsettles many, especially people diagnosed with high blood pressure. But the current research is more reassuring than most expect.

Short-term effect:

Caffeine can raise blood pressure by 5–15 mmHg for 1–3 hours. This is because caffeine stimulates adrenaline release and briefly constricts blood vessels. For healthy people, this is harmless.

Long-term effect:

With regular coffee consumption, the body develops a tolerance—the spike in blood pressure becomes smaller and smaller. Large long-term studies (with hundreds of thousands of participants) show: moderate coffee consumption (3–4 cups a day) does not increase the risk of cardiovascular disease. Some studies even suggest a slightly protective effect.

If you have diagnosed high blood pressure:

• Don’t swear off coffee altogether—most cardiologists no longer recommend doing so.
• Discuss with your doctor how much coffee is reasonable for you.
• Don’t drink caffeine right before measuring your blood pressure—it skews the results.
• Decaffeinated coffee is an alternative if your doctor advises caution.

Unfiltered vs. filtered: Unfiltered coffee (French press, Turkish coffee) contains the diterpenes cafestol and kahweol, which can slightly raise cholesterol levels. Filter coffee traps these compounds. For people with cardiovascular risk, filtered coffee is the better choice.

In practice at Green Wall Coffee

At Sophienstraße 27, I recommend to guests with high blood pressure: enjoy coffee in moderation and stick to filter coffee or espresso. A single espresso in the morning is safer than many think—and often tastes better than giving it up completely.
