Does the pressure increase green tea or lower it? How does it affect the body and whether it is possible to drink it to hypertensive patients? The article gives answers to these and other questions of interest to everyone who goes from black to drinking green tea. It would be more correct to say that he normalizes the pressure, but this is below.
Despite the indisputable usefulness, unequivocally answer the question, green tea lowers or raises blood pressure - it is difficult. All depends on the individual nuances of the organism of a particular person: the state of its vessels, the degree of disruption of the cardiovascular and nervous system, etc.
Different specialists consider differently. Some are sure that this drink lowers blood pressure, others - that raises. And each of them reinforces his opinion with arguments and evidence. Unequivocally one can say one thing: green tea is much more useful than black tea. To obtain such tea, the leaves of the tea bush are subjected to a shorter fermentation time, not exceeding 2-3 days, with enzymatic oxidation of the leaves by 12%.The fermentative process of black tea lasts about a month, with oxidation reaching 80%.In the latter case, the feedstock loses much more useful properties than in the first. This proves that black tea is less useful.
Let's try to understand how green tea affects the body, what properties it possesses and in what cases it increases, and in which it lowers blood pressure.
Does green tea increase or lower blood pressure?
For each person the degree of tea's utility is determined on the basis of the individual characteristics of the organism and the presence of diseases. This drink activates certain processes that are desirable for some people, others do not.
An interesting fact: Japanese scientists have proved that the regular use of green tea by hypertensive patients led to a decrease in blood pressure by an average of 5-10%.These findings were made after the end of the experiment, during which people suffering from hypertension had to drink green tea daily for several months. With a single or irregular use of the drink, the parameters of the cardiovascular system did not change.
Consuming green tea in healthy people can reduce the likelihood of developing hypertension by 60-65% and reduce the risk of heart attack by 40%.
When green tea can lower blood pressure
If you drink a drink irregularly, after eating, with milk, then, most often, it will not affect the blood pressure indicators( abbreviated A / D).Although it all depends on the characteristics of the organism of a particular person. Lower the pressure of tea can be due to the diuretic effect: the removal of fluid from the body and the bloodstream leads to a decrease in A / D.
In asthenia, vegetative-vascular dystonia by hypotonic type or other dysfunctions of the autonomic nervous system, the pressure in some people may decrease slightly. To obtain a noticeable hypotensive effect, it is necessary to drink the drink systematically for a long time, and half an hour before meals and without milk. It should be taken into account that tea leaves should be of very good quality without aromatic additives, impurities, dyes. The price of such tea is very high and, more often than not, it can not be found in ordinary stores.

Does the pressure increase green tea? Yes, such an effect is possible. The increase in A / D after consumption of the drink is associated with a large amount of caffeine. Green tea caffeine content competes with natural coffee. And the preponderance goes towards the first. Everyone thinks that coffee contains the largest amount of caffeine, but this is not right - in green tea it is more than 4 times.
Caffeine, tannin, xanthine, theobromine, other substances stimulate the nervous system and the heart, thereby increasing the heart rate and slightly increasing A / D.But this effect is short-lived, unstable, compensated by vasodilation due to the activation of the vasomotor center of the brain responsible for the state of blood vessels. Therefore, a tangible increase in pressure is not worth talking about.
If the pressure increase is associated with autonomic dysfunction, then the drink will probably increase A / D due to the stimulation of the nervous system by caffeine. At the same time, a headache appears, which appears against the background of reduced pressure.
Green tea normalizes blood pressure
The substances contained in tea have a stimulating and tonic effect on all systems and organs:
- increase the elasticity of the walls of the vessels and prevent the deposition of atherosclerotic plaques on them;
- maintains blood clotting normally, preventing the formation of blood clots;
- contribute to weight loss;
- removes excess fluid from the body;
- improve the blood supply of brain cells with oxygen;
- have vasodilating properties.
Caffeine stimulates the work of the heart and, together with kakhetin, simultaneously dilates the vessels. Therefore, even if A / D first rose, then it normalizes. Thanks to this, green tea is great for daily use as healthy people, and hypertensive people or hypotensive.
Rules for brewing and drinking green tea
Chinese tea ceremony How does this drink affect blood pressure - depends on the way it is brewed, the amount and frequency of consumption:
- Weakly brewed cool green tea lowers the pressure due to diuretic action. It is suitable for hypertensive people, people with heart failure or with increased intracranial pressure. Brew tea leaves in this case need not longer than 2 minutes.
- A strong hot drink can first increase the pressure, and then normalize it. Good for people with low A / D.To saturate the drink with caffeine, allow to brew for at least 7 minutes.
- To get the desired effect from a cup of green tea, drink it in 30-60 minutes.before meals. Regularity is also important.
- Do not add sugar or milk to the drink, because the useful properties are lost. For taste, you can put a spoon or two honey.

- Drink in moderation( 1-3 cups per day), not liters in the hope of achieving a momentary effect.
