Are you one of many people who can’t function without having their morning coffee first? If so, there are a few effects that caffeine can have on hypertension. The java jolt of a caffeine fix may cause a jump in blood pressure — a particular problem in people who already have high blood pressure.
Caffeine can cause a short, but dramatic increase in your blood pressure, even if you don’t have high blood pressure. It is not clear what causes this spike in blood pressure. Some researchers believe that caffeine could block a hormone that helps keep your arteries wide enough for steady blood flow.
Some people who constantly drink caffeinated beverages have a higher average blood pressure than those who don’t drink any. Others who regularly drink caffeinated beverages develop a tolerance to caffeine. As a result, caffeine doesn’t have a long–term effect on their blood pressure. Research has shown that caffeine has a stronger blood pressure increasing effect in men who are older than 70 or who are overweight.
To see if caffeine might be raising your blood pressure, check your blood pressure within 30 to 120 minutes of drinking a cup of coffee or another caffeinated beverage. If your blood pressure increases by five to 10 points, you may be sensitive to the blood pressure raising effects of caffeine. If you plan to cut back on caffeine, eliminate it slowly over several days to avoid withdrawal headaches.
If you have high blood pressure, ask your doctor whether you should limit or stop drinking caffeinated beverages. Keep in mind that the amount of caffeine in coffee and other beverages varies by brand. Also, avoid caffeine right before activities that naturally increase your blood pressure, such as exercise, weightlifting or hard physical labor.
