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.
What Is High Blood Pressure Or Hypertension
Blood pressure is created by the force of blood pushing against artery walls as it is pumped around the body by the heart.
Two numbers are reported when blood pressure is measured. The first number is the systolic pressure – the pressure in your arteries when your heart beats. The second number is the diastolic pressure, which is the pressure in your arteries when your heart is at rest between beats. As mentioned above, a normal blood pressure reading is less than 120/80 mm Hg.
High blood pressure, also known as hypertension, is a consistent increase in pressure that causes the heart to pump harder and damages blood vessels. It is a primary cause of death worldwide and is a risk factor for the development of cardiovascular heart disease, stroke and heart attack.
While caffeine consumption can cause a short-term increase in blood pressure, it is not generally thought to increase the risk of hypertension. Although, some research suggests that certain people could be at increased risk from cardiovascular events such as coronary heart disease or stroke because of caffeine consumption.
Do Coffee Drinks Have Health Benefits
While coffee beans can contain antioxidants and other nutrients, not all drinks are created equal. Extra sugars and additives can take away from some of coffees health benefits. For example, a sweetened coffee drink loaded with extra sugar and whipped cream will not do anything towards preventing type 2 diabetes or liver disease.
But that doesnt mean there arent lots of great coffee drinks on the market with plenty of health benefits. Were big fans of Rebbl coffee drinks, which combine some super herbs with coffee to maximize the benefits. They taste delicious but without extra sugars. Even better? The companys committed to ethical product sourcing, so you can really feel good about drinking these.

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.
Is Caffeine Bad If I Have Hypertension
You may wonder if its safe to consume caffeine if your doctor has diagnosed you with hypertension. While you should ask you doctor just to be sure, having 1 to 2 cups of coffee or tea a day is usually considered safe.
If your doctor recommends that you regularly monitor your blood pressure at home, make sure to take any readings BEFORE you have your coffee or 6 hours after you finish drinking it, so you log your normal blood pressure and not your post-caffeine spike. Likewise, at each of your doctors appointments, you should let your doctor know when you last drank a caffeinated beverage .

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.
Demographic And Baseline Differences By Group
presents the demographic, screening, and baseline data by group. Postmenopausal women had FSH values in the expected range. There were no significant group differences in habitual daily caffeine intake. All groups reported consuming caffeine equivalent to 3 to 4 cups of coffee/day in the diet. The sample was composed of a predominantly white population, and there were no significant differences in race across groups . There were no differences in age among the 3 groups of postmenopausal women. Young men had the highest BMI compared to premenopausal women . There was a statistically significant overall group difference in systolic blood pressure posthoc tests with corrections for multiple comparisons, adjusted for age, showed that premenopausal women had lower SBP compared to young men, with no significant differences among any of the other groups. On the other hand, older men had higher diastolic blood pressure than women in the premenopausal, ERT, and HRT groups. Young men also had higher DBP than women in the premenopausal and HRT groups. There were no significant group differences in HR.

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
Caffeine As A Stimulant
Caffeine is considered as a stimulant because it can increase the activity of your central nervous system that keeps you awake, alert and focus. But this increased activity could also trigger your blood vessels to constriction. With this, your blood pressure will increase and alter the blood supply of the heart. Expert says that this is the most dangerous effects of strong stimulant like cocaine and methamphetamine.
However, caffeine is a very mild stimulant and stays quickly in your body and it is a self-limiting stimulant as it acts on the kidneys increasing its excretion rate.

Effects Of Caffeine On Your Health
With 80% of Americans drinking coffee every day, and even more getting it from various other sources, caffeine is not a major threat to your health or blood pressure, unless youre hypertensive. Of course, there are ways that coffee or caffeine can become dangerous for your heart. Avoid putting in sugars, creamers, and other calorie-rich substances, and try to keep your consumption to four cups a day or less. Your tolerance will determine how much caffeine you can handle, but typically four cups is a safe limit.
Caffeine is a natural stimulant and can change how you think and feel. It causes acute changes by stimulating your central nervous system, typically leading to improved focus, alertness, and awareness.
Much like any substance, natural or not, there are some unwanted side effects that can occur depending on dosage, tolerance, and timing. These include:
- Jitters or shakes
- Difficulty falling asleep or staying asleep
- Increased heart rate
How Much Caffeine Can You Drink A Day
The FDA recommends that adults dont drink more than 400 milligrams of caffeine a day, the average cup of coffee contains 80 to 100 milligrams of caffeine whereas a can of caffeinated soft drink contains 30-40 milligrams. According to a review of 34 studies, caffeine may raise your blood pressure, especially if you are not a regular coffee drinker. The review found that in general, drinking anywhere between 200-300 milligrams of caffeine can raise your systolic blood pressure by 8 mm Hg while boosting your diastolic blood pressure by 6 mm Hg. The caffeine, however, will usually only raise blood pressure levels for around 3 hours.

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.
