Caffeine can raise blood pressure in the short term for many people, though the long-term effects are less clear and likely depend on dose and the person. Recent reporting and studies continue to emphasize that higher or chronic intake may be linked with cardiovascular risk, especially at higher daily amounts.[3][5][9]
What the latest news/studies suggest
- Short-term rises are well-documented: Medical guidance notes that caffeinated drinks can raise blood pressure in the short term, even if the long-term effect isn’t fully settled.[9]
- Chronic high intake may be riskier: A 2024 report on research presented at ACC Asia 2024 says that drinking over ~400 mg/day of caffeine on most days of the week may increase susceptibility to cardiovascular disease, and very high intakes (e.g., >600 mg/day) were associated with elevated heart rate and blood pressure after rest in that study.[7][3]
Practical takeaway (what to do with this)
- If you notice your BP tends to spike after coffee/energy drinks, consider reducing caffeine or switching to lower-caffeine options and monitor your readings.
- People with hypertension or high cardiovascular risk are often advised to be cautious with caffeine, because short-term BP increases can matter (even if modest).[9]
If you tell me your typical daily caffeine (coffee/tea/energy drinks + approximate amounts) and whether you have hypertension, I can help you estimate whether you’re in a range associated with greater effects.

Subgroup analysis was directed to the caffeinated beverages group. An age-related blood pressure raising effect was found in those younger than 24 years with SBP increasing by 5.31 mmHg and SBP by 2.26 mmHg.
