Yes—caffeine can raise blood pressure, especially in the short term (about within an hour of drinking it), and high or chronic intake may be associated with higher cardiovascular risk.[2][4]
What the latest reporting says
- Short-term “spike” after a dose: One cup of coffee can raise blood pressure within an hour and the effect can last for several hours.[2]
- Chronic/high intake concerns (newer headlines): A study presented at ACC Asia 2024 reported that regularly drinking more than 400 mg of caffeine per day (on most days of the week) may increase susceptibility to cardiovascular disease in otherwise healthy people, with effects described in terms of elevated heart rate and blood pressure (including after rest).[4][5]
The nuance (important)
- It varies by person and by whether you’re a regular caffeine user. Some people experience more noticeable increases than others.[2]
- Not everyone develops sustained hypertension from caffeine, but caffeine can still cause temporary increases that may matter—especially if intake is high or you’re sensitive to it.[8]
Practical takeaways
- If you have high blood pressure, notice caffeine-related spikes by checking your readings at consistent times (e.g., before coffee, and again 1–2 hours after).
- If you’re aiming to reduce risk, consider keeping caffeine moderate and avoiding high-dose sources (especially energy drinks), since newer reports flag higher daily intakes (like >400 mg/day).[4]
If you tell me your typical caffeine sources (coffee/tea/energy drinks) and approximate daily amount, I can help translate that into mg/day and what it likely means for your blood pressure.
