Limiting caffeine to less than 300 milligrams , or about three cups of coffee per day, can help avoid high blood pressure from reaching critical levels, Dr. Bhusri says. Green tea extract and other caffeine-related products, such as matcha, all increase the adrenaline surge, too. Coffee can make you more alert, but in doing so, it elevates blood pressures.

If you are a habitual daily coffee drinker and are consuming no more than the recommendations, it is safe, according to Dr. George. “For those that don’t typically drink coffee, there might be some intolerance resulting in things such as increased heart rate or anxiety,” Dr. George says. “For those folks, they might want to stick with decaf.”

More specific coffee intake recommendations also depend on so many individual factors. These include possible genetic predispositions, medication interactions, or an irregular heartbeat such as atrial fibrillation. Dr. George recommends discussing this with your health care provider if you’re concerned about high blood pressure and your coffee habit.

And remember always to avoid drinking coffee before having blood pressure checked since caffeine intake can temporarily raise blood pressure and provide an inaccurate reading, Dr. George notes.

High blood pressure is a common condition whereby the force of blood pushing against your artery walls is consistently too high. This pressure gradually causes your arteries to harden and narrow, which means the heart has to work harder to pump blood around the body. This mechanism can raise your risk of having a heart attack. Drinking too much coffee in a day may raise your blood pressure and worsen the condition.

Drinking more than four cups of coffee a day may increase your blood pressure, said the NHS.

The health body continued: If youre a big fan of coffee, tea or other caffeine-rich drinks, such as cola and some energy drinks, consider cutting down.

Its fine to drink tea and coffee as part of a balanced diet, but its important that these drinks are not your main or only source of fluid.

Research indicates that drinking too much coffee may increase blood pressure for a short time after consumption.

A review of 34 studies showed that 200 to 300 mg of caffeine from coffee which is approximately the amount two cups and more resulted in an average increase of 8 mm Hg and 6 mm Hg in systolic and diastolic blood pressure, respectively.

Limit Your Alcohol Intake

Regularly drinking too much alcohol can raise your blood pressure over time.

Staying within the recommended levels is the best way to reduce your risk of developing high blood pressure:

  • men and women are advised not to regularly drink more than 14 units a week
  • spread your drinking over 3 days or more if you drink as much as 14 units a week

What Does Coffee Do To Blood Pressure In The Short Term

Caffeine, the main ingredient in coffee, constricts blood vessels, and raises blood pressure in the short term, according to Dr. George. “Recent studies have shown that all types of coffee can increase blood pressure slightly, but remain in the healthy range and is temporary,” she says. “There are other ingredients in coffee called antioxidants that have a protective effect on blood vessels.” In fact, a study published in the 2013 journal Antioxidants found that coffee has more antioxidants than wine and tea.

Can Decaf Coffee Cause High Blood Pressure

Caffeine &  Hypertension  Caffeine Drinks Raise Blood Pressure

Most experts agree that caffeine of coffee can cause a temporary increase in blood pressure . Though the effect is temporary, but it may be dangerous for those with hypertension. How about with decaf coffee ? Does it also have the same effect?

In an effort to avoid and limit caffeine due to certain health conditions such as hypertension, heart arrhythmia , or if you are taking medicines that are advised to limit /avoid caffeine you may turn to decaf coffee. As the label decaf implies, it refers to decaffeinated which means the coffee has been processed to contain less caffeine.

The good news, the process to make decaffeinated coffee is now safe. Several years ago, some people doubted about the safety issue of making decaf coffee that might cause negative health impact! Today, a few different techniques in production are available.

In the past, the use of solvents was needed to make decaffeination. Nowadays, a new modified machine is designed to use carbon dioxide as a solvent for a direct decaffeination.

How much caffeine in a cup of coffee and a cup of decaf coffee?

A cup of coffee may contain about 95 mg of caffeine. How about with decaffeinated coffee?

How does caffeine affect both systolic and diastolic pressure?

While many studies have confirmed that caffeine can cause a temporary increase in both systolic and diastolic pressures, but there is still no a satisfied answer to explain this.

So, will decaf coffee cause high blood pressure?

To Sum It Up Does Coffee Raise Blood Pressure

Studies show that coffee increases blood pressure for up to 3 hours , after which it returns back down.

As the effects are so short-lived, for the general population regular coffee consumption does not raise your blood pressure long-term, nor does it appear to increase your risk of cardiovascular health problems.

However, there is a large caveat.

Our individual tolerance of caffeine is largely determined by our genes. Slow caffeine metabolisers have much greater spikes in blood pressure after a coffee, and are far more at risk for negative cardiovascular consequences as a result.

If you suspect you are a slow caffeine metaboliser, and you have existing high blood pressure, I recommend limiting yourself to one coffee per day. Better yet, switch to decaf.

For the majority though, a few coffees per day will not raise blood pressure in the long-run just dont have one before a blood pressure check-up.

Is Coffee Good For Low Blood Pressure

Coffee is just a complex substance obtained from a coffee bean. The coffee beans were roasted to different temperatures, and the beans caramelized its sugar and produced a tangling aroma and lip-smacking drink.

But poor coffee beans were unaware that it would be blamed for peoples health.Five trials were conducted in the year 2011, 300 mg of caffeine was given.

And within an hour there was an increase in the systolic pressure of a human upto 8.1mmHg and there was also an increase in the diastolic blood pressure and this lasted for three hours.

The same amount of caffeine was given for almost 15 days, and there was no change in the blood pressure. Blood pressure remains the same.

The Effects Of Caffeine On Blood Pressure

Coffee photo by

Caffeine raises blood pressure through causing blood vessels to contract. It may also block a hormone that keeps arteries dilated, and can trigger the release of adrenaline which increases blood pressure.

Caffeine has also been shown to intensify your physical and mental experience of stress: a study at Duke University in the US showed that caffeine increased the levels of stress hormones in the body and amplified perceptions of stress. Since stress can cause high blood pressure, this means the worst thing you can do when youre feeling stressed is grab a cup of coffee!

Does Caffeine Raise Blood Pressure

Does Coffee Raise Your Blood Pressure?

Dear Alice,

Does caffeine raise your blood pressure?

Dear Reader,

You raise a good question! While the exact mechanism is unknown, it seems that caffeine can cause a temporary increase in blood pressure among those who donât have high blood pressure . Some researchers have hypothesized that caffeine either blocks a hormone that helps keep the arteries widened, forcing the same amount of blood to flow through more narrow veins, or it causes your adrenal glands to release more adrenaline, which results in increased blood pressure. Each person may have a different tolerance for caffeine, so those who consume caffeine regularly may not see as big of an impact on their blood pressure. That being said, itâs also been noted that caffeine has a stronger effect on the blood pressure of men who are overweight or older than 70 years old. All that said, there are also some studies that have shown that when thereâs a higher concentration of caffeine metabolites in someoneâs system, the less likely they are to have HBP. Though thereâs limited evidence to suggest that caffeine can cause high blood pressure, itâs recommended that those whoâve already been diagnosed with HBP consider consuming less caffeine.

Observational Studies On Caffeine And Blood Pressure

Consistently high blood pressure is a huge risk factor for heart problems. Thats why were concerned about it in the first place.

Major dietary factors linked to high blood pressure and heart disease, such as excessive alcohol intake, typically contribute to stiffness of the blood vessels. This is the mechanism by which they raise the risk of heart disease.

Regular coffee consumption, however, was observed to have no such harmful influence on blood vessels .

This is thought to be because its pressor effects are too short-lived to do any lasting damage to the walls of our blood vessels.

The majority of large observational studies not only support this theory, but actually find coffee consumption linked to improved cardiovascular health.

In a review that included over 1.2 million subjects, 3 to 5 coffees per day was associated with significantly lower heart disease risk, while even heavier coffee consumption appeared to be neutral .

Other large reviews consistently find the same trend, suggesting coffee might be protective .

While these studies cannot prove cause and effect, if the blood pressure raising effect of coffee was harmful, we wouldnt expect to find coffee drinkers with better cardiovascular health than non-drinkers.

There is one huge caveat to this reasoning though

What Does Coffee Do To Blood Pressure In The Long Term

The long-term side effects of drinking coffee on blood pressure really depend on whether you’re a habitual or occasional coffee drinker, according to Dr. George. A 2017 review in the journal Nutrients, found that increased coffee consumption is associated with a small decrease in hypertension, or high blood pressure.

More recent studies suggest that it is safe to drink three to four cups of coffee a day for people who have hypertension, according to Dr. George. And habitual coffee drinking has been linked to a lower risk of coronary heart disease in women, per a meta-analysis in the European Journal of Epidemiology.

But that doesn’t mean more is better.

Studies, like one published in 2019 in the American Journal of Clinical Nutrition, found that people who drank more than six cups of coffee a day had a higher risk of cardiovascular disease, than moderate coffee drinkers. “Moderate intake was linked to the lowest risk of cardiovascular disease,” says Satjit Bhusri, MD and founder of Upper East Side Cardiology in New York.

“People also need to be mindful of consuming other drinks and even foods with added caffeine, including caffeinated waters, juices, energy drinks, chocolates, candies, and even potato chips,” Dr. Bhusri says.

How Much Coffee Should I Drink If I Have High Blood Pressure

Its up to you to decide how much coffee you can have if you have high blood pressure. Some recommend limiting your caffeine intake to 200 mg caffeine per day for healthy blood pressure. This is roughly the equivalent of two cups of brewed coffee per day. If you have high blood pressure, then this guideline could be worth following especially if youre specifically trying to lower your blood pressure, rather than just maintain it at its current level.

Keep in mind though that two cups per day may still increase blood pressure too much for some. Each persons sensitivity to caffeine is different, and can change.

You can try to assess the short-term effect of caffeine by taking blood pressure readings. Take a reading first at rest before having any caffeine, and again about 30-60 minutes afterwards . If your readings go up 5-10 points after caffeine then its likely youre sensitive to it.

However, this doesnt measure any subtle ongoing effects that caffeine may be having on your blood pressure. So if youre trying to lower your blood pressure, better to keep your caffeine intake on the low side.

Personal factors relating to coffee and high blood pressure

When figuring out what amount of caffeine is healthy for you, you also need to consider personal characteristics and other activities which exacerbate the effects of caffeine. These include:

Your age: The older you get especially once youre over 70 the more your blood pressure is likely to react to caffeine.

How Do You Know If Caffeine Affects Your Blood Pressure

Does Coffee Increase or Decrease Your Blood Pressure ...

To test whether caffeine has an effect in raising your blood pressure, check your blood pressure between 30 and 120 minutes after ingesting caffeine. An increase of five to 10 points indicates you are sensitive to caffeine, and you should cut back on it, Mayo Clinic says. To avoid withdrawal symptoms such as headaches, irritability and fatigue, cut back over several days.

A doctor can tell you whether to stop taking caffeine or limit your intake of it if you do have high blood pressure. He may advise you to cut back and have no more than 200 milligrams of caffeine per day.

That equates to about two 12-ounce cups of coffee or five Viter Energy Mints. While the amount of caffeine varies a lot in coffee, Viter Energy Mints contains 40 milligrams of caffeine.

If you lift weights or do physical labor and have high blood pressure, avoid caffeine before engaging in those activities, Mayo Clinic says.

Does Coffee Raise Blood Pressure

May be we should asking the question, does caffeine raise blood pressure instead of asking about coffeee only.

Here are some salient facts.

Caffeine present in coffee and some teas is a vasoconstrictor. What does vasoconstriction mean in lay terms?

A vasoconstrictor is a substance capable of making the blood vessel wall less stretchy or less relaxed. You want your blood vessel walls to be relaxed as the blood is coursing through them.

Relaxed blood vessels have lower blood pressure because the compliant wall decreases the pressure within. A vasoconstrictor does the opposite of this. It makes the vessel wall stiffer and less compliant. Thats what a vasoconstrictor does.

Which means a vasoconstrictor, by having that pressor effect on the blood vessel wall, will raise your blood pressure. Thats just scientific fact. We cant escape that. And caffeine is a vasoconstrictor.

Which means your coffee because its got caffeine in it will have that same pressor effect I talked about. So, coffee will raise your blood pressure upon absorption of the caffeine in it. Fact!

But by how much?

Yes, coffee or caffeine will raise your blood pressure but how high should we expect the blood pressure to rise?

Well, good question but, even this query is not easy to give a ballpark figure. Because there are other variables to come into the mix and these variables confound the results of research too.

So factors like:

  • Other lifestyle factors

How To Maintain A Healthy Blood Pressure Level

Its true. Coffee has a sky-rocketing social value and many health benefits, making it the go-to beverage daily for a vast amount of the world. While were enjoying the swift kick in the pants it gives us bringing us to life every morning, caffeine also gives a swift kick to our blood pressure immediately after consumption, regardless of your caffeine tolerance.

Here’s how: Coffee stimulates the cardiovascular system, boosting the heart rate and raising blood pressure. However, it appears this only affects those who are not used to consuming coffee regularly and not those who are avid coffee drinkers. Habitual coffee drinkers tend to become acclimated to caffeine, resulting in only a point or two of elevated blood pressure, whereas people who only drink coffee every now and then, can expect a temporary, yet dramatic increase even when drinking decaf.

Dont put down your coffee cup just yet. Its no secret that our daily caffeine fix is part of a well-balanced diet. However, its important that this is not your main or only source of fluid. Make sure to keep hydrated with water to allow the caffeine boost to work in a more balanced manner.

There are a few ways you can keep your blood pressure at bay while still enjoying your cup of Joe.

Just 30 minutes of exercise a day can lower your blood pressure.

2. Relax.

3. Eat less sodium.

4. Eat more potassium.

5. Cut back on caffeine.

Caffeine Has An Immediate Short

Coffee is the most popular hot beverage in the Americas, Australia and most of Europe.

As coffee beans contain caffeine, that makes coffee our biggest source of caffeine.

Caffeine is a psychoactive drug that stimulates the release of certain hormones in the brain . This is why coffee gives us an energy kick.

Caffeine also gives a kick to our blood pressure, and is actually a well-documented pressor . Increases tend to be mild, in the range of 5 to 10 mmHg. Thats regardless of how often you drink coffee or your caffeine tolerance, although there are always rare exceptions .

Caffeine appears to have a greater pressor effect on those with elevated blood pressure compared to those with normal blood pressure. And those effects are not suppressed by the use of blood pressure lowering medications .

Coffee is sounding pretty grim right now, but caffeine only appears to elevate blood pressure for about 3 hours before the effect subsides .

So what does this mean for our health in the long run?

Summary: Drinking coffee immediately increases blood pressure, regardless of your caffeine tolerance. The effect typically only lasts for a maximum of 3 hours though.
