Drinks that help—or hurt—your blood pressure

High blood pressure, also called hypertension, is a common health problem that can lead to serious illnesses like heart disease and stroke if not managed well.

Along with medications and healthy habits, what you drink each day can play an important role in controlling blood pressure. Some drinks can help lower it quickly, while others might raise it without you even noticing.

Let’s start with the drinks that help. One of the best is beetroot juice. Beets are rich in natural compounds called nitrates, which your body turns into nitric oxide. This helps relax your blood vessels and improve blood flow, which can bring your blood pressure down. Research shows that beetroot juice can have noticeable effects just a few hours after drinking it.

Another helpful drink is hibiscus tea. This tea is made from the dried flowers of the hibiscus plant and has been shown in several studies to lower the top number in your blood pressure reading (called systolic pressure). The benefit comes from the tea’s high level of antioxidants and plant chemicals that work in a way similar to some blood pressure medicines.

Pomegranate juice is also a great option. Like beets and hibiscus, it contains antioxidants and other helpful plant compounds. Drinking a glass of pomegranate juice every day may improve both the top and bottom blood pressure numbers (systolic and diastolic), especially in people with high blood pressure.

We shouldn’t forget about plain water. While it doesn’t have special ingredients like the other drinks, staying well-hydrated helps your heart pump more easily and supports overall health. Dehydration can put extra strain on your blood vessels, so drinking enough water throughout the day is important.

Now, let’s look at drinks to limit or avoid. Alcohol is one to be careful with. While some people think a glass of red wine might help the heart, drinking too much alcohol is a known cause of high blood pressure. If you’re trying to manage hypertension, it’s safest to drink only in moderation—or avoid it altogether.

Caffeine, found in coffee, black tea, energy drinks, and many sodas, can also raise blood pressure temporarily. This effect is stronger in some people than in others. If you have high blood pressure, you might want to check how caffeine affects you by measuring your blood pressure before and after having a caffeinated drink.

Then there are sugary drinks like soda, sweetened iced tea, and fruit punches. These are among the worst for blood pressure. High sugar intake is linked to weight gain and increased risk of diabetes and heart disease, all of which can raise blood pressure. These drinks also cause quick spikes in blood sugar, which isn’t good for your heart or blood vessels.

To sum up, if you want to lower or control your blood pressure, it’s smart to choose drinks like beetroot juice, hibiscus tea, pomegranate juice, and plenty of water. At the same time, it’s best to cut back on alcohol, caffeine, and sugary drinks.

These simple changes can support your heart and help keep your blood pressure at healthy levels—especially when combined with a balanced diet, regular exercise, and any medications your doctor recommends. Always talk to your healthcare provider before making big changes to your routine, especially if you’re on treatment for high blood pressure or other health conditions.

If you care about high blood pressure, please read studies that drinking tea could help lower blood pressure, and early time-restricted eating could help improve blood pressure.
