Health Benefits Of Caffeine
The caffeine-containing beverages are a rich source of polyphenols, which protects against heart disease, several cancers, and lower C-reactive protein .
Studies have consistently shown decreased liver cancer risk in those who drink coffee.
Coffee and tea containing polyphenols have shown to lower the concentration of C-reactive protein , an essential factor in inflammation. It decreases in CRP has shown to reduce the risk of cardiovascular disease, heart attack, and specific kidney disease.
If you are not a coffee drinker, then it does not mean you should start because of the potential health benefits. A healthy diet rich in fruits and vegetables is an alternate source of polyphenols and polyphenol-related compounds.
Is Coffee Good For Low Blood Pressure
Caffeine for low blood pressure might work for a short period only in those who dont drink caffeinated drinks regularly.
However, with habitual coffee consumption, your body may not give the same response to caffeine, and you may not see any increases in blood pressure.
If you persistently have low blood pressure with symptoms like dizziness, loss of consciousness, etc, please see your doctor for an appropriate diagnosis and treatment. Relying on a home remedy may not be the best idea in this case.

Seven Things To Eat Or Avoid To Lower Your Blood Pressure
Authors: Professor Clare Collins, Associate Professor Tracy Burrows and Dr Tracy Schumacher
High blood pressure is called the silent killer. Thats because it has no symptoms. Having high blood pressure increases your risk of heart disease, stroke, heart failure and kidney disease.
Six million Australian adults have high blood pressure 140/90 millimetres of mercury or more or take medications for it. Of those, four million have high blood pressure that isnt treated or under control.
No wonder heart disease and stroke directly cost the Australian economy A$7.7 billion a year.
There is some good news. High blood pressure can be treated or prevented. Eating oats, fruit and vegetables and beetroot, in particular helps. So does avoiding salt, liquorice, caffeine and alcohol.
Optimal blood pressure is 120 mmHg or less over 80 mmHg or less. Lowering it by 1-2 mmHg can have a big impact on reducing your risk of heart disease and stroke, and the nations health care costs.
How Can I Lower My Blood Pressure In Minutes
If your blood pressure is elevated and you want to see an immediate change, lie down and take deep breaths. This is how you lower your blood pressure within minutes, helping to slow your heart rate and decrease your blood pressure. When you feel stress, hormones are released that constrict your blood vessels.

What To Avoid To Lower Your Blood Pressure
Salt
Salt or sodium chloride has been used to preserve foods and as a flavour enhancer for centuries.
Adults need between 1.2 to 2.4g of salt each day , which is equivalent to 460 to 920mg of sodium.
But in Australia seven out of ten men and three in ten women eat way more than that and much more than the upper recommended limit of 5.9 grams of salt or 2,300 mg of sodium per day.
If you add salt to food yourself this pushes your sodium intake even higher.
A review of studies involving 3,230 people showed that reducing salt intakes by 4.4 grams a day could reduce systolic blood pressure by about 4.2 mmHg and diastolic by 2.1 mmHg.
In those who had high blood pressure there were even bigger reductions of 5.4 mmHg and 2.8 mmHg .
Avoid foods high in sodium. Dont add salt and try to choose lower-salt versions of processed foods.
Alcohol
Consuming one or more alcoholic drink a day is associated with systolic blood pressure that is about 2.7 mmHg and diastolic blood pressure 1.4 mmHg higher than non-drinkers.
Interestingly, when you first drink an alcoholic beverage, blood pressure goes down, only to rise later.
A rise in blood pressure after drinking alcohol is more likely to happen when youre awake, rather during sleep.
The bad news is that larger amounts of alcohol increase your risk of high blood pressure, especially in men, but also to a lesser extent in women.
Liquorice
High blood pressure due to eating black liquorice is rare, but case reports have occurred.
Caffeine
Caffeines Effect On Blood Pressure
Disclaimer: Results are not guaranteed*** and may vary from person to person***.
Americans love coffee. About 80% of Americans drink coffee every day, and the caffeine within it does affect blood pressure. Thankfully these effects arent necessarily harmful, but there is a definite link between coffee, caffeine, and blood pressure.
The average 12-ounce cup of coffee has around 100 milligrams of caffeine, generally speaking, though there are variations when it comes to brand, roast, etc. Within 30 minutes to two hours, youll experience the strongest stimulant effects of caffeine, which can include an accelerated heart rate and a higher than normal blood pressure.
But dont let this worry you. The impacts of caffeine are acute, meaning they wont lead to chronic high blood pressure for the majority of the population. That said, people with hypertension should definitely monitor their intake to avoid increased risk of a heart attack. As far as overall heart health goes, caffeine poses no long-term threat to blood pressure in people with normal, or even slightly high, blood pressure.

Caffeine Raises Blood Pressure Controversy
There are some studies controversial to above-said views caffeine increaseâs blood pressure and chances to have hypertension.
A study shows consumption of 1 cup of coffee a day raises systolic BP by 0.19 mmHg and diastolic BP by 0.27 mmHg. Coffee drinking is associated with a small blood pressure rise but appears to play a small role in hypertension development.
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

May Increase Blood Pressure Temporarily
Science suggests that the physiological effects of drinking coffee can extend beyond a small dose of wakefulness. Research indicates that it may increase blood pressure for a short time after consumption.
A review of 34 studies showed that 200300 mg of caffeine from coffee approximately the amount youd consume in 1.52 cups resulted in an average increase of 8 mm Hg and 6 mm Hg in systolic and diastolic blood pressure, respectively .
This effect was observed for up to three hours after consumption, and results were similar in people with normal blood pressure at baseline and those with pre-existing high blood pressure.
Interestingly, regular coffee consumption is not associated with the same impact on blood pressure which may be due to the caffeine tolerance that develops when you habitually drink it .
Based on this data, a small to moderate increase in your blood pressure may occur after drinking a cup of coffee especially if you drink it infrequently.
Summary
Research indicates that coffee may increase blood pressure for up to three hours after consumption. However, if you drink it regularly, this effect is diminished.
What Are The Risk Factors For High Blood Pressure
Hypertension can creep up on you. Most people dont realize they have it until they are in a situation where their blood pressure is checked or something bad happens like a heart attack.
This is one of the main reasons for being preventative with your health! Its not like you have nerve fibers in your blood vessels to tell you when the pressure is getting too high, so getting ahead of the problem can be a huge advantage.
Some of the things that can factor into high blood pressure include :
- Age
- Diet
- Stress
Notice whats not on that list? Yep! You dont see caffeine there, but well get there in a minute.

Your Body Adapts To The Effects Of Coffee And Caffeine
Heres the kicker. Once you start consuming caffeine regularly, youre less likely to have a rise in blood pressure after consuming coffee or other caffeinated beverages. Your body adapts to the effects of caffeine when you drink it regularly, and the effects of the caffeine arent as pronounced unless you increase your caffeine consumption. Thats why you feel less alert after a few weeks of drinking coffee daily than when you first started.
How Much Coffee Is Too Much
As a guideline for the average healthy adult, 400 mg of caffeine is considered safe .
Consuming larger quantities in a day can lead to undesirable side-effects such as anxiety, tremors, heart palpitations and insomnia Especially if you have existing high blood pressure.
However, the severity of these side-effects also depends on your personal caffeine tolerance. Coffee connoisseurs tend to develop a high threshold.
So on an individual level, your true coffee limit actually depends on your genetics, your personal caffeine tolerance, and any existing medical conditions that react with caffeine. Observe how your body responds to caffeine , including a blood pressure reading after you have a cup.
Also be mindful that coffee can vary considerably in its caffeine content. Instant and home-brewed coffee usually contains 60-80 mg per small cup, while a Starbucks grande can have up to 300 mg.
Summary: As a general guideline, more than 3-4 standard coffees per day may cause unwanted side-effects. But your true limit depends on your genetics, your personal caffeine tolerance, and any existing medical conditions. We must consider these factors and observe how our body reacts.

Is Blood Pressure Affected By Caffeine Withdrawal Symptoms
When under stress and pressured by deadlines, people tend to overdo it on their caffeine intake: tea, coffee, chocolate bars, anything with a strong caffeine kick will do. This is because caffeine is a stimulant. What that means is that the intake of caffeine results in alertness of the mind as the body, which in turn drives away sleepiness.
The presence of caffeine is lower in tea and coffee than it is in chocolate or cola and energy drinks.
So accordingly, this article deals with the consequences of downing too much caffeine and then suffering withdrawal symptoms which may or may not include blood pressure issues.
So Could Caffeine be the Cause of High Blood Pressure?
Caffeine is known to temporarily raise a person’s blood pressure which is, of course, and obviously the reason we call it “a stimulant”. There is a hormone called adenosine, and its task is to widen the arteries. Caffeine prevents this hormone from doing what it is supposed to, and the result of this is heightened blood-pressure. Another “side effect” of caffeine entering a human body is the heightened production of adrenaline, which in turn even more increases the given person’s blood pressure.
With all this said, it is easy to see how someone would assume that caffeine is considered a drug which tips the balance of a person’s natural blood pressure in general.
The Debate on Caffeine and High Blood Pressure
Some Reports Say Theres No Direct Link Between Caffeine And Blood Pressure
According to Mayo Clinic:
Caffeine can cause a short, but dramatic increase in your blood pressure, even if you don’t have high blood pressure. It’s unclear what causes this spike in blood pressure. Some researchers believe that caffeine could block a hormone that helps keep your arteries widened. Others think that caffeine causes your adrenal glands to release more adrenaline, which causes your blood pressure to increase.
Recent studies, however, have repeatedly reported that caffeine doesnt necessarily lead to an increased blood pressure, nor does it up the risk for cardiovascular diseases like high blood pressure, heart disease and cardiac arrest.
Verywellhealth.com also states a well-known study stating that theres no direct link between caffeine and a rise in blood pressure:
One very well-known study examined more than 85,000 women over a ten-year period and found that there was no increased risk of these diseases, even in women who drank more than six cups of coffee per day.
The Joint National Committee on Hypertension likewise reports that theres indeed no evidence that caffeine leads to high blood pressure.
And heres another silver lining:

What To Eat To Lower Your Blood Pressure
Rolled oats
A review with five research trials included tested the impact of oats on systolic blood pressure and diastolic blood pressure in about 400 healthy adults.
The researchers found that systolic blood pressure was 2.7 mmHg lower and diastolic blood pressure was 1.5 mmHg lower when participants ate around 60 grams of rolled oats or 25 grams of oat bran per day.
This quantity of oats or oat bran contains around four grams of a type of fibre called beta-glucan.
For each extra one gram of total daily fibre, there was an extra 0.11 mmHg reduction in diastolic blood pressure.
Recommended minimum daily adult fibre intakes are 30 grams for men and 25 grams for women.
While some of fibres effect is due to weight loss, soluble fibres produce bioactive products when theyre fermented in the large bowel. These work directly to lower blood pressure.
To improve your blood pressure, eat rolled oats or oat bran for breakfast, add to meat patties, or mix with breadcrumbs in recipes that call for crumbing.
Beetroot
Beetroot is extremely rich in a compound called inorganic nitrate. During digestion, this gets converted into nitric oxide, which causes arteries to dilate. This directly lowers the pressure in them.
A review of 16 trials of mostly healthy young men found drinking beetroot juice was associated with a 4.4 mmHg reduction in systolic blood pressure. But it found no change in diastolic blood pressure.

New Buzz On Coffee: It’s Not The Caffeine That Raises Blood Pressure
- Date:
- American Heart Association
- Summary:
- People who enjoy the occasional decaf latte may be getting more of a lift than they know, scientists report in Circulation: Journal of the American Heart Association.
DALLAS, Nov. 19 People who enjoy the occasional decaf latte may be getting more of a lift than they know, scientists report in today’s rapid access issue of Circulation: Journal of the American Heart Association.
Swiss scientists studying caffeine’s effects in a small group of people report markedly elevated blood pressure and increased nervous system activity when occasional coffee drinkers drank a triple espresso, regardless of whether or not it contained caffeine.
Surprisingly, people who drank coffee on a regular basis showed increased stimulation of sympathetic nerve pathways but no increase in blood pressure.
This is the first time such disparities in reactions to coffee have been reported, says lead researcher Roberto Corti, M.D., a cardiologist at University Hospital in Zurich.
The results suggest that some unknown ingredient or ingredients in coffee not caffeine is responsible for cardiovascular activation, he explains. Coffee contains several hundred different substances.
“Coffee’s cardiovascular safety remains controversial,” he says. “The possible health hazards have been related to its main ingredient caffeine.”
What remains to be seen is whether people with hypertension should be advised to avoid decaffeinated coffee as well, Corti says.

What Does Caffeine Do To Your Blood Pressure
5 min read
This is perhaps one of the common questions among java lovers and coffee noobs alike.
Many people know the effects of caffeine on the body. Some of them are positive, like added concentration and stronger mental performance, alertness and awake-ness, healthy glowing skin, boost in metabolism, and a happy disposition.
But going overboard with your caffeine fix could sometimes lead to adverse effects, including jitters, anxiety, and palpitations.
And this leads some people to ask whether caffeine also raises blood pressure.
This is an important question because 80 percent of Americans drink coffee every day and about 90 percent of people worldwide consume caffeine in one product or another. More importantly, high blood pressure can cause strokes or heart attacks.
So whats the verdict?
The jurys pretty much out on this one.
Are There Any Long
Since coffee is a beverage that people drink on a daily basis and it does raise your blood pressure in the short term, the question of if there are any long-term effects of drinking coffee is a legitimate concern. The results are conflicting. Some evidence suggests that drinking coffee regularly does not have a long-term impact on your blood pressure, nor does it appear to increase your risk of cardiovascular health problems.
Other evidence suggests negative reactions to caffeine like caffeine withdrawal, rapid heartbeat, anxiety, or jitteriness. If youre considering drinking coffee every day, its important to do so in moderation, and figure out what works the best for you, your body and your lifestyle. One way to consume coffee in a healthy way is to never drink it on an empty stomach, before having your morning coffee, you should have at least a small meal. In case of gastrointestinal distress, an option is to add collagen protein into your coffee.

Can Decaf Coffee Cause High 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?
