When blood pressure rises in the veins, it is difficult for the heart to pump blood throughout the body. But the biggest danger of high blood pressure is the possibility of a ruptured vein or a blood clot. This makes high blood pressure the most important risk factor for stroke. According to researchers, coffee can significantly increase blood pressure in a short amount of time after ingestion.
An earlier study published in the American Journal of Clinical Nutrition found a strong link between high blood pressure and caffeine intake.
A group of scientists specifically set out to determine the long-term effects of coffee and caffeine on blood pressure in people with high blood pressure.
Their results showed that consumption of 200 to 300 mg of caffeine increased blood pressure by 8.1 mmHg. and diastolic blood pressure by 5.7 mmHg. within an hour after taking.
Moreover, they noticed that this increase in blood pressure persisted for more than three hours.
“Even if you don’t have high blood pressure, caffeine can cause a short-term but dramatic increase in your blood pressure,” says the Mayo Clinic.
“It is not clear what causes this increase in blood pressure. The blood pressure response to caffeine varies from person to person.”
The rush of adrenaline makes the heart beat faster and the blood vessels constrict, increasing the pressure in the veins.
Interestingly, studies have shown that regular coffee consumption can reduce the effect of the drink on high blood pressure.
Researchers believe this may be because those who normally drink coffee may develop a tolerance to caffeine.
What’s more, people who have been diagnosed with high blood pressure should be aware that coffee consumption is unlikely to affect their overall risk of heart disease.
Coffee contains many biologically active compounds that are touted for their strong antioxidant effects on the body.
Some of its phytochemicals include magnesium, potassium, and B vitamins, which protect against oxidative stress.
That being said, the health benefits of coffee could theoretically outweigh the potential risks associated with caffeine.
In fact, a 2020 study published in the New England Journal of Medicine found that drinking two to five cups of coffee a day may protect against heart disease, diabetes, and certain types of cancer.
However, scientists warn that too much coffee can lead to problems such as anxiety, nervousness and insomnia.
The main conclusion of these studies is that moderate coffee consumption may be the safest and most beneficial for health.
Other measures to prevent high blood pressure should also be considered, including regular exercise and a healthy diet.
According to the Mayo Clinic, some examples of aerobic exercise that can help lower blood pressure include walking, jogging, cycling, swimming, or dancing.
