From this article you will get an exhaustive answer to the question of how coffee influences pressure.
Many people love coffee. It is appreciated not only for its taste, but also for its invigorating properties. And if you love this drink, you are exactly asking: after you have drunk coffee - will the pressure rise or fall?
Click on the picture to enlarge This drink contains caffeine and usually raises pressure, but in different situations it affects the pressure in different ways. Let's consider all possible cases.
One-time use of
With a single use of coffee increases blood pressure. The hypertensive effect of drinking this drink lasts from 60 to 180 minutes. On the average, 1 cup of the drink increases the systolic( "upper") pressure by 8 mm Hg.st., and diastolic( "lower") - by 5 mm Hg. Art.with a single use by people who do not drink it regularly.
The doctors proved the following fact: coffee slightly elevates blood pressure level for 1-3 hours and can not cause hypertension in a healthy person.
The duration of the pressure increased from this drink depends on the individual characteristics of the organism. How quickly the hypertensive effect occurs, and how long it will last, depends on the rate of cleavage of caffeine in the body.
Results of a single study of the effect of coffee on blood pressure Regular use of
According to research, with regular use of coffee, people develop dependence on caffeine and other alkaloids. Tolerance also develops: caffeine does not cause such an effect as before. Therefore, in people who regularly use this drink, one of its cups does not raise the level of blood pressure, and does not lower it.
Regular use of coffee develops dependence on caffeine However, on the basis of this, it can not be asserted that regular use of this drink is safe for blood pressure. Since low doses of caffeine no longer invigorate a person the way it used to, it begins to consume more of it. The amount of drink consumed can go over all reasonable limits. Even some famous people became real coffee lovers. So, the French philosopher Voltaire( lived in the 18th century) drank more than 50 cups a day. And Catherine the Second preferred so strong coffee that about 80 grams of coffee beans were used to make one cup!
Warning! Researchers argue that the regular use of more than 5 cups of drink per day increases blood pressure for a long time. Thus, a person develops hypertension with a pressure increase of 5-10 mm Hg. Art.above the norm.
Effect of coffee on blood pressure in hypertension
The question is whether this drink is hypertensive, is controversial for doctors from around the world. Some argue that with hypertension, this drink can not be consumed. Others say that there are no strict contraindications. Let's try to understand this issue.
If you are hypertensive and do not drink this drink regularly, then be prepared for the fact that after a cup of coffee the level of your blood pressure will rise by 3-7 mm Hg. Art. This is not dangerous for those who suffer from not too severe hypertension.
If there are no other factors that can cause an increase in pressure, you can be calm - a slight increase in blood pressure for several hours will not cause serious health problems.
However, you should still be careful. If there are other unfavorable factors, the pressure can jump too much. Therefore, if you are hypertensive, do not drink this drink in such cases:
- being in a stuffy room;
- being under the scorching sun in the heat;
- before or immediately after physical exertion;
- at a time when you are experiencing stress;
- within a few weeks after the hypertensive crisis.
All this concerns disposable coffee consumption by those who are not used to it.
If you have been drinking this drink all your life, and in adulthood you were diagnosed with "hypertensive disease", it is not necessary to completely abandon your favorite drink. People who are accustomed to caffeine, coffee within reasonable limits does not affect the level of blood pressure. Therefore, you can drink this drink, but not more than 1-2 cups a day.
In any case, if you drink coffee with hypertension, tell your doctor about it!
Influence of coffee on blood pressure in hypotension
Some hypotonia think that coffee helps them get rid of problems with low blood pressure. However, this is not entirely true. Yes, after a cup of this drink the level of pressure rises, but only for 1-3 hours. And if you consider that a person is awake about 16 hours a day, then for a steady increase in pressure you need 5 cups of coffee. This dosage is unacceptable even for hypotonic patients, since coffee affects the heartbeat. The use of this amount of this drink can lead to tachycardia, resulting in increased risk of other cardiovascular diseases. And if you remember that caffeine is rapidly developing tolerance, then 5 calyces will soon be missed to achieve hypertensive effect.
Coffee with chocolate can quickly raise blood pressure Conclusion: coffee is absolutely ineffective for the treatment of hypotension! It raises blood pressure level only for 1-3 hours, and with regular use it will be necessary to increase the dosage, which is harmful to health.
With hypotension, coffee can be consumed, but it does not bring any significant benefit. The rule remains the same as for hypertensive patients: no more than 1-2 cups of drink per day.
Can Coffee Reduce Pressure?
However surprising this may be, some researchers argue that this is possible.
Decaffeinated coffee does not affect the pressure of Scientists who say that coffee lowers blood pressure, give the following argument: the drink has a diuretic effect, and removing excess fluid from the body helps reduce blood pressure, so the drink also lowers the pressure.
However, this does not sound very convincing. To achieve a strong diuretic effect, you need to drink at least 4-5 coffee cups. And the amount of caffeine that is contained in them definitely increases the pressure. From this it follows that, if coffee theoretically and can lower blood pressure, then its hypotensive effect is overlapped by its hypertensive effect.
Conclusion: if you consider that the reaction of each person's body to a particular substance is individual, coffee either slightly increases the pressure, or does not affect it in any way. Cases when the drink lowers the pressure are very rare. Perhaps in these cases, lowering blood pressure is associated with other causes.
The individual characteristics of the body
Data on the effect of coffee on the pressure, given in the article, may not touch you personally. It is always necessary to monitor the way certain substances affect your body. If you are one of those people who have this drink significantly increases the pressure, it is better to abandon its use. If you have hypertension, and your doctor has forbidden you to drink coffee, it is best to heed his advice. Even if the drink does not do much harm to your health, it can distort the results of medical research, which will make it difficult to diagnose and monitor the effectiveness of treatment.
Focus on your well-being and the recommendations of your doctor!
