Pressure surges: why you should be careful with caffeinated drinks

Coffee contains polyphenols (powerful disease-preventing antioxidants) and can improve bowel health. However, some nuances should be taken into account, doctors believe. Yes, you should monitor your caffeine intake in general, which is found not only in coffee, but also in tea and energy drinks.

According to the Mayo Clinic, caffeine consumption can cause a short-term but dramatic increase in blood pressure. The reason is still unclear, but some researchers believe that caffeine may block a hormone that keeps the arteries widening, leading to higher readings.

The Johns Hopkins Clinic believes that if blood pressure rises by 5 to 10 points half an hour after taking caffeine, you should reduce its consumption. Some regular caffeine users may have normal blood pressure. Researchers have concluded that this may be related to the body's habituation.

Experts warn that it is not necessary to drink more than four cups of caffeinated beverages per day, otherwise it can lead to increased blood pressure, anxiety, insomnia and digestive problems. If a person has high blood pressure, he should discuss the dosage with his doctor and think about whether it is time to switch to decaffeinated coffee.
