Caffeine is a mild stimulant thus it has a blood pressure raising effect, however, this rise is marginal and temporary only lost for a minimum period.

Caffeine, Blood Pressure, and your Heart
Studies have consistently shown caffeine consumption does not increase the chances of high blood pressure, heart disease or heart attack. One well-known study with over 85,000 women participant for ten-year period shows there was no increased risk of these diseases. Even among women who consume more than six coffee cups per day. The Joint National Committee on Hypertension has specifically confirmed there is no longer enough evidence interlinking coffee or tea with high blood pressure.
Still, there are controversial studies have shown a weak link between caffeine and rise in blood pressure, but this result only considered short-term effects.
In 2007, two important studies further supported and again demonstrated that caffeine raised blood pressure is small and short-lived. Caffeine does not contribute to any blood vessel disorders associated with hypertension and cardiovascular disease.
Health Benefits of caffeine
Coffee and tea may have many health benefits. These dark caffeine-containing beverages are a rich source of compounds called polyphenols, which protects against heart disease and several cancer types. Studies have consistently shown a decreased liver cancer risk in men who drink coffee.
Coffee and tea containing polyphenols have shown to lower the concentration of C-reactive protein (CRP), an important factor in inflammation. It decreases in CRP have shown to lower the risk of cardiovascular disease, heart attack, and certain kidney disease.
If you are a not a coffee drinker, then it does not mean you should start because of the potential health benefits. A healthy diet rich in fruits and vegetables is an alternate source of polyphenols and polyphenol-related compounds.
Coffee blood vessel elasticity
As we age, our blood vessels getting stiffer by losing its elasticity, which increases the risk of high blood pressure. A study suggests moderate coffee drinking may counter this aging process of blood vessels and maintain its elasticity.
A Greek researcher repost, aged people with hypertension who habitually drinking one to two cups of coffee a day are having more elastic blood vessels than people who drink less or more. This finding has presented at the European Society of Cardiology Congress.
The nutrient compounds in coffee include flavonoids, magnesium, potassium, niacin, and vitamin E, can combat blood vessel aging by blocking oxidative damage and reduce harmful inflammation. Hypertension patients who drink coffee in moderation, one to two cups a day, seem to improve arterial aging. A major limitation of the study is the participants mostly drank their coffee with their friends or family in a more relaxed environment. Therefore, these psychological relaxation benefits may help heart health.
Caffeine raises blood pressure controversy.
There are some studies controversial to above-said views; caffeine increase’s blood pressure and chances to have hypertension.
A study shows consumption of 1 cup of coffee a day raises systolic BP by 0.19 mmHg and diastolic BP by 0.27 mmHg. Coffee drinking is associates with small blood pressure rise, but appears to play a small role in hypertension development.
What you can do, as a coffee drinker with high blood pressure?
Caffeine can only cause a short dramatic increase in your blood pressure, even if you are not hypertensive. Caffeine may block a hormone that helps keep your arteries widened, additionally; caffeine stimulates adrenal glands to release more adrenaline, which causes a blood pressure rise.
Most of the people who drink caffeinated beverages regularly develop a tolerance to it. As a result, caffeine does not produce any long-term blood pressure effects on them.
If you are having high blood pressure and drinking over 3 cups of coffee/tea per day, try limiting the amount at 3 cups/day. If you are drinking 3 cups of coffee/day, continue to enjoy your drinks. If you are not a coffee drinker, you do not require starting drinking based on their coffee benefits.
