Green tea, unlike black, goes through a shorter fermentation path, which takes about 2-3 days, while the black oxidizes about a month. Therefore, its effect on the body is more pronounced: the properties of tea leaves in this case are preserved if brewed tea correctly - without using boiling water.
Due to the fact that green tea has a more powerful effect on the body, today a lot of myths about the effect of this drink arose: some people say that tea greatly lowers the pressure, others - on the contrary, increases. Let's see if the pressure reduces green tea, or vice versa, it increases.
The properties of green tea, affecting the pressure
First of all, it should be noted that green tea is a natural diuretic. Many people pay attention to this fact from the positive side: the drink thus removes the body from toxins, stimulates metabolism, strengthens the immune system, etc. However, this tea property plays an important role in regulating blood pressure.
Another feature of green tea is the high content of caffeine. In this matter, he can compete with natural coffee, cooked in the usual way (not espresso): for example, green tea contains 1-4% of caffeine, and in natural coffee (excluding cooking from a robusta variety) 1-2%.
It should also be clarified that the high content of tannin and caffeine in tea and their interaction during the brewing stimulates nervous activity, which to some extent may affect the pressure if its fluctuation is associated with autonomic disorders.
Does green tea lower blood pressure?
Undoubtedly, it is impossible to unequivocally determine if the pressure of green tea reduces, one must take into account the individual characteristics of the organism. For example, the ability to adapt, which is supported by the work of the autonomic nervous system and the adrenal glands, plays a large role in the fluctuation of pressure.
With a tendency to low pressure, depressive and asthenic conditions, stable apathy, green tea is not recommended, since in these cases it can lower blood pressure. People with meteosensitivity and the diagnosis of vegetative vascular dystonia by hypotonic type during the temperature fluctuation are advised to stop using this drink, but when external factors do not have to reduce pressure, green tea can be drunk.
Also, green tea as a natural diuretic can slightly reduce blood pressure, so it is better to limit hypotension to 1 cup of green tea per day.
The effect of green tea on blood pressure can be mediated by disorders of the autonomic nervous system (when the cardiovascular system has no pathologies and the pressure "jumps"): because of the caffeine and tannin content, this drink stimulates nervous activity, irritating it, and if the body is exhausted and there are asthenic conditions, it is natural, caffeine will only "overload" and already depleted vegetation. If the nervous system is the opposite, overexcited, then naturally, caffeine will contribute to the complication of this condition.
Does the pressure increase green tea?
Whether the pressure of green tea is difficult to say for the same reasons: one must take into account the individual characteristics of the organism. If a person is prone to increased pressure due to violations in the cardiovascular system, it is likely that green tea will lower it because of its diuretic properties. People with high intracranial pressure even it is useful to drink 1-2 cups of green tea a day systematically.
If the pressure rises due to autonomic dysfunction, then green tea will certainly increase the pressure because of the high content of caffeine.
How to brew green tea at low pressure?
The action of strong green tea on low pressure is favorable: to increase the caffeine content, during brewing, let it brew for at least 7 minutes.
How to brew green tea at high pressure?
To use green tea to lower the pressure, brew a small amount of tea and let it brew for no longer than 1-2 minutes. Otherwise, because of the fortress, he can increase the pressure.
