Does Coffee Raise Blood Pressure?

Coffee can cause a short-term rise in blood pressure because of caffeine. Caffeine is a stimulant that can increase heart rate and temporarily affect blood vessel function. This effect can be more noticeable in some people, especially those who are not used to caffeine.

The effect is often stronger in people who do not regularly consume caffeine. Regular coffee drinkers may develop some tolerance, so the blood-pressure response can become smaller over time. Research generally suggests that habitual coffee consumption is not clearly linked to the development of long-term high blood pressure in healthy adults.

Key takeaway: Coffee may temporarily raise blood pressure, but for most healthy adults, moderate coffee consumption is not considered a clear cause of chronic high blood pressure. People who are sensitive to caffeine or have hypertension may notice a stronger temporary response.

If you are checking your blood pressure, caffeine can temporarily affect the reading. For a more accurate measurement, healthcare guidance commonly recommends avoiding caffeine for at least 30 minutes before taking your blood pressure.

For most adults, the FDA cites up to 400 mg of caffeine per day as an amount that is not generally associated with negative effects, although individual sensitivity varies. The amount of caffeine in a cup of coffee can also vary considerably depending on the type and serving size.
