Does espresso raise blood pressure?

Coffee and your blood pressure - Harvard Health

While caffeine is often implicated in blood pressure elevation, the difference between espresso and pure caffeine implies a more nuanced relationship. Evidence emerges from decaffeinated espresso, which, despite not affecting blood caffeine levels, raised the average systolic blood pressure in nondrinkers by 12 mm Hg—nearly equivalent to the impact of high-caffeine brews.

Key Findings:

  • Caffeine Not Sole Culprit: The disparity between espresso and pure caffeine challenges caffeine as the sole factor in blood pressure elevation.
  • Decaffeinated Espresso Impact: Even without a rise in blood caffeine levels, decaffeinated espresso increased the average systolic blood pressure in nondrinkers.

In summary, the impact of espresso on blood pressure suggests factors beyond caffeine may contribute to its effects, highlighting the need for a more comprehensive understanding of espresso’s influence on cardiovascular parameters.

How long does caffeine raise your blood pressure?

The impact of caffeine on blood pressure follows a specific timeline:

  • Onset: Blood pressure changes typically manifest within 30 minutes after consuming caffeine.
  • Peak Time: The effects reach their peak in 1-2 hours post-consumption.
  • Duration: The influence of caffeine on blood pressure may persist for more than 4 hours.

In summary, the temporal pattern of caffeine’s impact on blood pressure involves an onset within 30 minutes, a peak in 1-2 hours, and potential persistence for over 4 hours.

Should I avoid caffeine if I have high blood pressure?

For managing or preventing high blood pressure, dietary choices play a crucial role. Here are key considerations:

Dietary Factors for Blood Pressure:

  • Inclusion: Consuming oats, fruits, vegetables, and beetroot can be beneficial.
  • Avoidance: It is advisable to steer clear of salt, liquorice, caffeine, and alcohol.
