Numerous studies confirm the difference in blood pressure among those who drink coffee daily and those who never or rarely drink coffee. However, the increase in blood pressure in daily coffee drinkers, compared to a subgroup who drink once to a few times per week, was not found to be statistically significant. Seniors on blood pressure medication may worry about the effect of drinking caffeine as well. Andrew Duxbury, MD, previously explained to SeniorsMatter that he “wouldn’t necessarily say that caffeine is recommended for people on blood pressure medication; it’s relatively safe as long as they don’t go crazy with their intake. What I tell my patients is everyone needs a cup or two of coffee in the morning to get going. But after those first two cups? Switch to decaf.”
