The caffeine in coffee has several effects. One way is by raising blood pressure for about three hours. Another effect is by lowering blood pressure a little. There is no exact answer to the question, "Does coffee cause high blood pressure?" It depends on your consumption.
Caffeine in coffee raises blood pressure for 3 hours
Coffee contains caffeine, which can temporarily cause high blood pressure. However, the effect of caffeine is quickly lost. Blood pressure returns to normal within 3 to 4 hours. Long-term intake of caffeine can cause high blood pressure, so caffeine intake should be limited.
Studies have revealed that caffeine increases blood pressure for 3 hours when drinking coffee. How much? About 200 to 300 milligrams of coffee (about 2 cups) increases blood pressure by 6 to 8 milligrams per hour. This effect lasts for 3 hours and is only evident in people who do not drink much coffee. People who drink a lot of coffee are accustomed to the effects of caffeine.
In addition to lowering the risk of cardiovascular disease, caffeine has several positive effects. Coffee contains bioactive compounds that help reduce inflammation and oxidative stress. Both of these substances are harmful to the heart. Nevertheless, people with high blood pressure should limit their caffeine intake.
When caffeine is consumed, its effect on blood pressure is influenced by the amount consumed and the duration for which it is consumed. Drinking 5 to 8 cups of coffee or tea parties every day raises blood pressure by 1 to 2 millimeters of mercury. In the long term, caffeine consumption increases blood pressure by 3 to 15 millicolumns of mercury. Caffeine consumption increases blood pressure by 3 to 15 millicolumns of mercury. The increase in blood pressure is due to blood moving around the body.
The associations between coffee consumption and blood pressure are likely causal. With such large 95% confidence intervals surrounding the effect sizes, these associations cannot be explained by chance. The relationship between coffee consumption and blood pressure is biologically plausible. However, these studies are limited by the number of trials. Many experiments are short in duration and have small populations.
