How does drinking coffee, tea and water affect blood pressure?

While stress, lack of exercise or a salty diet can increase blood pressure, on the contrary, regular exercise, healthy eating or adequate sleep can help lower this index.

So, how do habits associated with daily life such as your favorite coffee, water or tea intake affect blood pressure?

To answer this interesting question, Dr. Qin Rao, an internal medicine specialist working in the US, will explain it to you, according to the health news site Verywell Health.

Coffee, tea, and water affect blood pressure in different ways, he said. While coffee can cause a temporary increase in blood pressure, the antioxidants in tea help lower it, while drinking enough water and staying hydrated helps stabilize overall blood pressure levels.

Coffee: Temporarily increases blood pressure

Coffee can cause a temporary increase in blood pressure, whether or not you have high blood pressure. The caffeine in coffee stimulates the nervous system, causing the body to react by narrowing the arteries and veins, increasing heart rate and blood pressure.

However, coffee does not cause a long-term increase in blood pressure. Drinking less than 400 mg of caffeine, about 2-3 cups of coffee a day, is generally safe for most people. In fact, research shows that drinking 2-3 cups of coffee a day can reduce the risk of high blood pressure in healthy people.

Tea: Helps lower blood pressure

Tea, especially green tea, when consumed regularly can help lower blood pressure and reduce the risk of cardiovascular diseases such as heart attack, heart disease and stroke. Green tea contains antioxidants that can fight free radicals – unstable molecules that contribute to chronic disease.

These antioxidants help improve the function of the endothelium (the lining of blood vessels) and support vasodilation. When blood vessels dilate, blood flows more easily without creating additional pressure, thereby helping to lower blood pressure.

Water: Helps maintain stable blood pressure

Drinking water helps maintain healthy blood pressure, but it doesn't have the same direct effect as coffee or tea. It's important to drink enough water to prevent dehydration, which can raise or lower blood pressure depending on the situation.

Experts recommend drinking 6-8 glasses of water a day to ensure the body is hydrated, maintain fluid balance and maintain stable blood pressure.
