Caffeine can increase blood pressure in the short term, especially in people who already have higher blood-pressure risk.[9]
What the latest reporting says
- Short-term effect: Caffeinated drinks can raise blood pressure soon after you have them, even though the size and persistence of the effect over the long run are less clear.[9]
- Chronic/high intake signals: Research reported by major medical organizations and journals has found that regular higher caffeine consumption is associated with higher blood pressure and higher heart-rate/autonomic effects in some studies.[3][6]
- Magnitude varies by person: Earlier controlled research in clinical populations found caffeine raises both systolic and diastolic blood pressure, with stronger responses in people with hypertension risk.[7]
Practical takeaway
- If you have high blood pressure or are caffeine-sensitive, consider reducing caffeine and track your readings (or ask your clinician how much is safe for you). Short-term rises are the main concern.[9]
If you tell me your typical caffeine source (coffee/energy drinks/soda) and how many mg per day (or cups per day), I can help you estimate whether you’re in a “low/moderate/high” range to discuss with your doctor.

Our data sources included a MEDLINE search of the literature published before December 1997, bibliography review, and expert consultation. We selected controlled trials in which coffee consumption was the only difference between the intervention and control groups, mean blood pressure change was reported for each group or period, and treatment lasted for >24 hours. Of 36 studies initially identified, 11...

We identified 73 men with optimal BP, 28 with normal BP, 36 with high-normal BP, and 27 with stage 1 hypertension on the basis of resting BP; in addition, we included 18 men with diagnosed hypertension from a hypertension clinic. During caffeine testing, BP was measured after 20 minutes of rest and again at 45 to 60 minutes after the oral...
