About This Tea That Lowers Your Blood Pressure
I still dont love hot tea. But I realized I love iced tea its so refreshing! Ive started making a pitcher of cold-brewed tea every week. I keep it in the refrigerator, and Ill usually pour a glass over ice, and then top it off with water throughout the day. Ive found it really helps me drink more fluid. And, along with the other lifestyle changes Ive made, it also helps lower my blood pressure.
Rather than worrying about whether Im drinking the best or healthiest tea, I put a blend of different teas, and other polyphenol-rich ingredients into my pitcher and let it brew on a sunny windowsill for a few hours. That way, Ive got a little bit of everything and a whole lot of healthy in each and every glass.
I like to make my tea fairly concentrated, so it holds up to a full cup of ice. I also realized if you add a splash of seltzer to your glass, it takes your iced tea to a whole new level of refreshing and delicious.
One important thing about tea: Try to buy organic whenever possible. Many teas are high in pesticides.
And heres a money-saving tip when youre buying green tea. Theres no need to spring for fancy designer brands. One of the most highly rated by the independent testing lab ConsumerLab, was Trader Joes Organic Green Tea. It had had significantly higher levels of the antioxidant EGCG compared to other brands.
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.
The Effects Of Caffeine On Blood Pressure

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!

How To Reduce The Effects Of Caffeine On Blood Pressure Without Drinking Less Coffee
If you drink a lot of coffee and have high blood pressure then its likely youre going to need to drink less coffee. But there are other things you can do to try to reduce the effect of caffeine in blood pressure.
This is because the effect of caffeine intake may be exacerbated by other substances or activities which also increase your blood pressure. So:
Avoid caffeine before doing exercise or any highly energetic activity hard labour, workouts, runs, brisk walks. These already raise your blood pressure, and the extra effect of caffeine can mean your heart has to work too hard. Stay away from caffeine for at least an hour before getting into it drink water instead.
Dont smoke and drink coffee tobacco also raises blood pressure by constricting your blood vessels, so coffee and a cigarette arent such a perfect combination for your blood pressure!
Does Caffeine Raise Blood Pressure
To be clear, caffeine does actually affect blood pressure. When you consume caffeine, whether it be from coffee, an energy drink, or supplement, one of its effects is to spike your blood pressure.
Caffeine raises blood pressure by blocking adenosine, a compound that helps blood vessels stay relaxed and open. Without the adenosine, blood vessels constrict, the heart must work harder to move blood through your system, and so the pressure rises.
This rise kicks off within 15 minutes of consumption and can last 4-6 hours. If you dont consume more, things should return to normal.
Many of us are in this position. We like our coffee or energy drink or soda or tea, and we pay no thought to the consequences of that little burst of blood pressure. Why? Because we never notice.
Hypertension, as stated above, has many risk factors, so you might get it irrespective of your caffeine consumption. If you get hypertension though, that spike in blood pressure can be serious, and caffeine will be one of the first things off the list if you get diagnosed with it.
For a small subset of us, our genetics make this all better or worse, depending on one little gene variant.

Caffeine is a natural stimulant found in the nuts, berries, and leaves of certain plants. Caffeine is most commonly consumed as coffee or tea products, and some have estimated that these beverages may be the most widely consumed foods in the world.

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 coffee’s 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 doesn’t mean there aren’t lots of great coffee drinks on the market with plenty of health benefits. We’re 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 company’s committed to ethical product sourcing, so you can really feel good about drinking these.

Research conducted at Duke University in the US, showed that caffeine increased the levels of stress hormones in the body and amplified peoples perceptions of stress, as well as increasing heart rate and blood pressure.
Heres how the experiment worked. Habitual coffee drinkers had their response to caffeine measured on two randomly chosen days. On one of these days they were given two capsules containing 250mg of caffeine in the morning and at lunchtime the equivalent of about four cups of coffee in total. On another day they were given identical placebo capsules at the same times so that they didnt know which was which.

Nutrients In Coffee Credited For Fighting Blood Vessel Aging
Most of the men and women drank traditional Greek coffee in small, espresso-sized cups.
Greek coffee is considerably stronger, with more caffeine, than espresso, Chrysohoou tells WebMD.
She credits compounds, including flavonoids, magnesium, potassium, niacin, and vitamin E, for combating blood vessel aging by blocking the damaging oxidation process and reducing harmful inflammation. Oxidation reactions can produce free radicals. This, in turn, can start chain reactions that damage cells.
Traditional Greek coffee contains more of these chemicals than most other types of coffee as it is unfiltered and boiled, Chrysohoou says.
“We recommend hypertensive patients drink coffee in moderation, just one to two cups a day, as it seems that it may improve arterial aging,” Chrysohoou says.
One limitation of the study is that participants drank their coffee in cafes with friends or with family at home, in a relaxed atmosphere. Therefore, the psychological benefits of socializing on heart health may help explain the findings.
