The world’s most popular drink is coffee. Coffee improves cardiovascular health, and one research found that persons who consume 3-5 cups of coffee daily had reduced cardiovascular risk than those who drink less. The British Coffee Association says people drink two billion cups of coffee daily.
On the other hand, coffee may harm cardiovascular health, other studies have found. Heavy coffee drinking increased cardiovascular-related mortality in severe hypertensives. Coffee intake and blood pressure studies might lead to cardiovascular risk prevention measures.
As of recent, coffee consumption and blood pressure were examined, and drinking it lowers blood pressure in multiple ways.

The researchers examined 1972 health data from 720 men and 783 women. Participants were clinically evaluated every four years. Researchers analyzed blood pressure and coffee use. The group:
Systolic blood pressure measures heartbeat-induced arterial pressure. Systolic blood pressure increases stroke and heart disease risk. Coffee drinkers had lower systolic blood pressure than non-drinkers.
They also observed a link between drinking more cups and lower peripheral pulse pressure (PP), which monitors blood flow.
Coffee did not impact arterial stiffness, which increases the risk of cardiovascular events, dementia, and mortality.
Dr. Yu-Ming Ni, the non-invasive cardiologist at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center in Fountain Valley, CA, told Medical News Today:
Coffee intake consistently lowered blood pressure, including an estimate of central blood pressure, a more trustworthy blood pressure test. Coffee drinkers have a 5-point lower blood pressure than non-drinkers. Compared to non-coffee drinkers, individuals who drank more than 3 cups had 9-point lower blood pressure.
This research adds to a meta-analysis of four comparable studies that found a link between coffee and reduced blood pressure.

“Caffeine in coffee can temporarily increase blood pressure by stimulating the sympathetic nervous system, but in the long term, regular coffee consumption can lead to a small reduction in blood pressure due to improved insulin sensitivity and antioxidant effects,” says Dr. Robert Segal, founder of Manhattan Cardiology, Medical Offices of Manhattan, and LabFinder, who was not involved in the study.
Dr. John Higgins, M.B.A., M.Phil., a sports cardiologist at the UTHealth Science Center at Houston – McGovern Medical School and the Memorial Hermann Ironman Sports Medicine Institute, Houston, TX, who was not involved in the study, told MNT: “Certain antioxidants in coffee, e.g., flavonoids, boost production of nitric oxide, which helps the blood vessel wall to dilate and lower blood pressure, as well as other minerals like magnesium, potassium, niacin, Nitric oxide, and less inflammation, reduce blood pressure.”
Dr. Shannon Hoos-Thompson, a University of Kansas Health System cardiologist, who was not involved in the research, told MNT: “This is an issue that has been looked at repeatedly from numerous methods, all over the globe, and going back a long time. Coffee in moderation is harmless and does not affect cardiovascular health.
Dr. Hoos-Thompson highlighted that the research did not define “one cup” of coffee when questioned about its limitations. She emphasized that not knowing beverage amount, concentration, and caffeination restricts outcomes.
“Coffee drinkers may have reduced blood pressure. Stress, diet, exercise, or anything else. Unless these extra characteristics are tested in the same individuals and accounted for, it will be impossible to confidently infer that coffee is the major cause of improved blood pressure in these people,” she adds.
Remember that coffee intake was self-reported. Avoid sweetened coffees with flavor syrups and roasting and brewing procedures that lower antioxidant content. “The inability to adequately account for these variances continues to preclude a convincing conclusion of coffee’s health benefits,” she shares.
Just remember, everyone’s body is different. You should always consult your doctor if something seems off, want to try a new diet, or if you do something different where you may be uncertain how it will affect your body.
