  1. Yes, as a stimulant, it temporarily raises blood pressure. This is not to be confused with medically diagnosed high blood pressure, called hypertension (HTN). In hypertension, the blood pressure is too high all of the time. Some people with HTN can control it through dietary changes (low salt, low sugar) and cardio exercise, specifically High Intensity Interval Training. Other people with HTN must take medications to lower their blood pressure. HTN has a genetic component to it, so while it is true that lifestyle plays an important part, ot is not the only factor. Caffeine use does not cause HTN, but if you have HTN, limiting caffeine intake is wise.

  2. Coffee contains caffeine which is a stimulant. It will increase your heart rate and blood pressure. If you do experience hypertension or tachycardia, you should limit the amount of coffee you drink or eliminate drinking it all together.

  3. Caffeine may 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. The blood pressure response to caffeine differs from person to person. Usually, blood pressure starts to rise a few hours before you wake up. It continues to rise during the day, peaking in midday. Blood pressure normally drops in the late afternoon and evening. Blood pressure is normally lower at night while you’re sleeping.

  4. No, to the contrary!
    Our high-blood pressure problem would be a lot worse if it wasn’t for coffee.
    Aside from topping all other food or beverage items in terms of anti-oxidants coffee is a very good friend to have for your heart and arteries.

    Can caffeine increase blood pressure?

    Caffeine is coffee’s vasoactive ingredient. It acts on the central nervous system (CNS) and, yes, it has a blood pressure elevating effect, secondary to a heart rate increase.
    But when coffee is the “delivery vehicle” of caffeine its effect is much different than when some other processed type of drink (caffeinated) supplies the same amount of caffeine [1].
    5 take-away bullet points of what is important when judging coffee:
    * Normotensive people (those with normal blood pressure):
    *
    * no increased risk for HPT or CVD from drinking 1-2 cups coffee per day
    * lower risk for HPT and CVD from drinking ≥ 3 cups coffee per day [2].
    * Hypertensive people (HPT):
    *
    * transient BP increase of up to 8 mmHg in coffee-naïve patients (those who are new to coffee consumption).
    * no increase in BP or CVD risk after > 2 weeks of regular daily coffee consumption
    * Everyone:
    *
    * coffee is your single largest source of polyphenols that exert anti-oxidant, anti-inflammatory and protective effects systemically and on the vasculature.

    > There is one little caveat:
    if you are suffering from uncontrolled hypertension AND you are new to drinking coffee, you should monitor your BP res…

  5. Caffeine is a vasoconstrictor, which means that it decreases the size of blood vessels and can raise blood pressure. Caffeine exerts its effects by interacting with different receptors in the brain. Experts believe that other compounds in coffee, such as antioxidants, have a protective effect on blood vessels.
    A 2015 studyTrusted Source indicated an increase in systolic blood pressure only in people who did not consume coffee frequently. Another reviewTrusted Source found that habitual coffee consumption of more than 3 cups a day did not increase the risk of hypertension. However, there was a slightly elevated risk associated with 1–3 cups a day.

  6. 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 people who regularly drink caffeinated beverages have a higher average blood pressure than do those who drink none. Others who regularly drink caffeinated beverages develop a tolerance to caffeine. As a result, caffeine doesn’t have a long-term effect on their blood pressure.
    To see if caffeine might be raising your blood pressure, check your blood pressure before drinking a cup of coffee or other caffeinated beverage and again 30 to 120 minutes afterward.
    If your blood pressure increases by about five to 10 points, you may be sensitive to the blood pressure raising effects of caffeine. If you plan to cut back on caffeine, do so gradually over several days to a week to avoid withdrawal headaches.

  7. Caffeine blocks vasodilator hormone Relaxin which is produced male’s prostate and is present in human semen and female’s corpus luteum, ovary and breast. Vasodilator acts as smooth muscle blood circulation. When it is interrupted, blood pressure may rise. Moreover, Caffeine causes adrenal glands to release more adrenaline, which causes blood pressure to increase. But caffeine doesn’t have a long-term effect on their blood pressure.

    If I had known this I would have given it up years ago.. I drink green tea or lemon tea now or decaf occasionally.

  9. Yes, it does to a minimal degree for a short period of time – perhaps a few hours. The so-called “energy drinks” will have a more prominent effect and it will last longer because of the amount of caffeine. It does not, however lead to sustained hypertension.

  10. Yes, a little. Caffeine isn’t wholly responsible for true hypertension. If you have high blood pressure, see your doctor for diagnosis and treatment. You MAY be asked to limit or eliminate caffeine but there will be other causes of true hypertension

  12. Just some stories to tell you how much caffeine can effect you. I was on night shift twenty years of my career. I missed days of sleep at times, one time three days straight. Only once, but I almost had a seizure, and never did that again. There were times I took as much as a 1,000 mg of caffeine to stay awake. Mostly it was 100–200 tablets of caffeine taken every so often. I essentially never had a serious problem except that once trying to push the envelope.
    Yet in my career I saw several men really screwed up by caffeine. Not so much by blood pressure rising, but by their heart getting its rhythm disturbed. One guy was drinking power drinks and walked in with his heart rate at 147. Another was 18 years old and was in atrial fibrillation due to drinking lots of Coca Cola. Finally a 25 year old man was also in atrial fibrillation with the top of his heart just quivering. He had taken the same tablets I had used, but his heart just jumped into fibrillation. So be careful using that caffeine!

  13. 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

    As a result, caffeine doesn’t have a long–term effect on their blood
    pressure. It seems that caffeine has a stronger blood pressure
    increasing effect in men who are older than 70 or who are overweight.
    If you have high blood pressure, ask your doctor whether you should
    limit or stop drinking caffeinated beverages. If you’re concerned about
    caffeine’s effect on your blood pressure, try limiting the amount of
    caffeine you drink to 200 milligrams a day — about the same amount as in
    two 12–ounce (355–millileter) cups of brewed coffee. Keep in mind that
    the amount of caffeine in coffee and other beverages varies by brand.
    Also, avoid caffeine right before activities that naturally increase
    your blood pressure, such as exercise, weightlifting or hard physical
    labor.
    To see if caffeine might be raising your blood pressure, check your
    blood pressure within 30 to 120 minutes of drinking a cup of coffee or
    another caffeinated beverage. If your blood pressure increases by five
    to 10 points, you may be sensitive to the blood pressure raising effects
    of caffeine. If you plan to cut back on caffeine, do so gradually over
    several days to a week to avoid withdrawal headaches.

  14. Caffeine, supported in coffee, a stimulating substance, accelerates blood circulation. Increases efficiency, concentration of attention, reaction speed and physical endurance, and also increases hormones – serotonin. But coffee also contains 30 more necessary organizations. Coffee stimulates the intestines and can be a mild, weak remedy. Studies have shown that people who drink more than 6 cups of coffee a day have a 70% higher risk of heart disease. In general, coffee, in moderate doses, is beneficial, but in large doses it can also be harmful, leading to Sickness and irritability. Also, people who are accustomed to drinking coffee every day, Fall into dependence on it. Refusal or limitation of quantity may make you feel unwell. Also, drinking coffee leads to poor absorption of calcium, magnesium, potassium, sodium, vitamins B1 and B6.

  15. Coffee has a dual effect on blood pressure.
    Caffeine (1, 3, 7-trimethylxanthine) in coffee is a central nervous system stimulant, which means it stimulates the brain. It causes the release of the stimulants, noradrenaline and adrenaline, in the brain. It is also an inhibitor at the adenosine receptors. Since blood pressure is dependent on the heart rate and stroke volume, as well as on the peripheral resistance which, in turn, is dependent on vasoconstriction, coffee will raise blood pressure.
    Blood Pressure = Heart Rate x Stroke Volume x Total peripheral Resistance,
    By all indications, caffeine central nervous effects will raise blood pressure indirectly by increasing all the three components of blood pressure in the equation above.
    Caffeine (1, 3, 7-trimethylxanthine) has direct effects on the heart. By increasing the levels of cyclic AMP (cAMP), caffeine increases the contractility of the heart. It does so by inhibiting phosphodiesterase. The cAMP in the heart is linked to beta-1 receptors which increase contraction. It, thus, increases the stroke volume and the heart rate. Again, as an adenosine blocker, caffeine activates the heart.
    Caffeine in coffee, however, in blood vessels, directly causes vasodilation, which leads to increased urination, and this dehydrates the body. The vasodilation is mediated by cAMP, which in the case of blood vessels, is linked to the beta-2 receptor which causes relaxation. Caffeine equally causes blood vessel dilation indirectly by stimulating the release of nitric oxide. The vasodilation and increased urination will reduce blood pressure.
    Vasodilation will reduce peripheral resistance, and dehydration will reduce the volume of blood, the venous return, a…

  19. Drinking more than 4 cups of coffee a day may increase your blood pressure. If you’re a big fan of coffee, tea or other caffeine-rich drinks, such as cola and some energy drinks, consider cutting down. 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.

  21. Coffee has been part of the human diet for about 1,000 years. During much of that time, it has stimulated controversy — and in the age of Starbucks, the dispute has blossomed from a tempest in a coffee pot to grounds for serious debate. Some of coffee’s negative press seems to depend on the widespread belief that anything that tastes so good must be bad for you.
    Coffee stimulates the nervous system, increasing alertness. But many people are sensitive to even one cup of coffee, making them feel jittery or interfering with sleep.

  22. Yes, definitely. Caffeine is a central nervous system stimulant, meaning it increases involuntary reflexes such as heart rate and width of blood vessels, which, in turn result in the increase of blood pressure. This is why those with high blood pressure are often asked to cut back on or stop their caffeine intake.

  23. Yes, it causes constriction of the blood vessels and the blood increases in pressure and velocity which can damage the kidneys and other end organs. But it depends on the dosage and frequency and tolerance of the individual.

  26. Caffeine is one of the most widely consumed natural stimulants worldwide. It is found commonly in coffee, tea, chocolate, some sodas and energy drinks. Caffeine can cause a short-term increase in blood pressure (BP) immediately after it’s consumed and for a short time after.
    Caffeine jolts the central nervous system and brain. It blocks the adenosine receptors preventing drowsiness and creates an increase in feelings of happiness, alertness, energy and improves performance. Blocking adenosine receptors and increasing certain neurotransmitters also causes the short-term elevation in blood pressure that may occur after caffeine is consumed.
    Regular caffeine consumption can lessen the impact caffeine has on your blood pressure as you can build up a tolerance to caffeine.

  28. Due to the caffeine, in the short term, yes, long term, no (habituation).
    Am on a lot of antihypertensive meds, when its hot and I sweat a lot, when walking about (exercise lowers one’s blood pressure by opening up our arterioles, our resistance vessels) sometimes blood pressure goes so low that I get dizzy. I then pause to take cup of coffee (real strong coffee, not the US brew), and will soon be OK again.
    Short term blood pressure raising effect, from Effects of Caffeine on Plasma Renin Activity, Catecholamines and Blood Pressure | NEJM
    Caffeine increased plasma renin activity by 57 per cent, plasma norepinephrine by 75 per cent and plasma epinephrine by 207 per cent. Urinary normetanephrine and metanephrine were increased 52 per cent and 100 per cent respectively. Mean blood pressure rose 14/10 mm Hg one hour after caffeine ingestion.

    Can caffeine increase blood pressure?

    No effect on chronic caffeine use due to habituation see Habitual coffee consumption and blood pressure: an epidemiological perspective.
    Prospective studies suggest a protective effect of high coffee intake (4 or more cups per day) against hypertension, mainly in women. Furthermore, the risk of hypertension may be lower in coffee abstainers. Randomized controlled trials, which are mostly of short duration (1-12 weeks), have shown that coffee intake around 5 cups per day causes a small elevation in BP (approximately 2/1 mmHg) when compared to abstinence or use of decaffeinated coffee.
