As a result, stones will appear in them.

It is strictly not recommended to use it in large quantities those people who suffer from organ diseases urinary system. Urologists advise limiting yourself to a couple of small cups per day. And after drinking tea, you should definitely drink 250 ml of plain water to compensate for the loss of fluid.

Important! If you drink green tea in liters, you can end up with liver problems, as an overdose of polyphenols will occur.

And I would drink, but my health does not dictate!

If you drink it without taking into account contraindications, then all the benefits of green tea will come to naught. Even such an eminent “doctor” is not for everyone.

nervous disorders that are accompanied by overexcitation, insomnia, tachycardia: tea will only aggravate the patient’s condition, as it contains caffeine;
hypotension: green tea will cause your blood pressure to drop even lower, but this will not happen if you prepare it in a weak concentration, but if you pour a heaping spoonful into one cup, your blood pressure may drop to critical levels;
gout.

Green tea is not suitable for young children either, because their nervous systems are still developing. This means that there is no need for them to take “stimulants” (even natural ones).

There are different opinions as to whether green tea is allowed for expectant mothers. Its benefits and harms to the body of a pregnant woman have not yet been fully studied. But gynecologists do not recommend using it in the first trimester, as it causes the uterus to become more toned, which creates a risk of fetal rejection.

Starting from the fourth month, such a strict ban is lifted, but in order to eliminate even the slightest risks for the baby, it is better for a pregnant woman to limit herself to one cup of this “medicine” per day.

Green tea is a powerful source of caffeine and has the same stimulant properties as coffee, but acts on... nervous system this drink much softer. This is explained by the fact that in addition to caffeine, tea contains many other alkaloids, for example, tannin, which together with caffeine forms theine, which is more beneficial for the body.

Scientists say that drinking a cup of hot green tea in the morning can provide you with energy for the whole day, while reducing the effect of stress on the body and improving the barrier properties of the immune system.

What are the benefits of tea for high blood pressure?

The largest number of studies regarding the effects of green tea on the body were carried out in large product-exporting countries, mainly China, India and Japan. One of the main areas on which this product has a great impact is the cardiovascular system. Thus, you need to figure out whether green tea increases or decreases blood pressure and what the physiology of the process is.

It is necessary to begin with the fact that all experiments were carried out on healthy people, for this reason it is difficult to say that a particular drink helps normalize abnormal blood pressure. A specific tea indirectly affects blood pressure levels, since after drinking it the overall picture does not actually change.

The peculiarity of the drink’s effect on the cardiovascular system is that the caffeine contained in tea speeds up the work of the heart and, accordingly, increases the volume of liquid tissue passing through it. At the same time, the enzymes of the drink act on the vasomotor center in the brain, causing the blood vessels to dilate. Thus, virtually no changes in pressure occur.

The fact is that it is green tea that increases the body’s sensitivity to insulin, and accordingly prevents the development of dangerous conditions with high level Sahara.

Healing properties for gastritis and pancreatitis

Gastritis and pancreatitis are quite complex diseases for which diet is the main treatment method. Nutrition in this case is a key tool for regulating metabolic processes, which directly affect the condition of a patient with one of these diseases. It is also immediately necessary to note that green tea in the described situation is not always possible.

Indeed, a particular drink has a positive effect on digestive processes, as it helps improve the production of digestive enzymes. Thus, drinking a cup of tea daily can improve the release of bile into the intestines, which is especially important for pancreatitis. As for gastritis, in this situation you need to be careful, since substances contained in both green and black tea increase the acidity of gastric juice and can aggravate the situation. For this reason, drinking green tea during an exacerbation of gastritis is not recommended.

Effect on the prostate

One of the most unpleasant diseases for male body is prostatitis or inflammation of the prostate gland. This gland is responsible for the excretion of ejaculate through the urinary canal, and if it is inflamed, genitourinary function is disrupted. This disease is quite difficult to treat and in most cases becomes chronic.

During the period of exacerbation of the disease, you should be especially careful about your own health, including your diet. Green tea has anti-inflammatory properties, thanks to which the drink can reduce the risk of developing the described problem. However, most men do not know whether this drink is a diuretic or not, which should be considered first.

Due to the fact that tea has a pronounced diuretic effect, it should be avoided during an exacerbation of the disease. This information can also become an automatic answer to the question of whether you can drink green tea at night. Considering all that has been said, we can conclude that green tea can indeed be an excellent preventative against prostatitis, but you should not count on it in case of exacerbation of the disease.

How to drink green tea correctly

Dear readers, there are articles on the blog about how to brew and how to drink green tea, where you can find detailed information on these issues.

But in short, when brewing green tea you need to follow a few simple rules to get the maximum benefit from the drink.

The teapot needs to be warmed up before brewing.
Do not use boiling water for brewing; the water temperature should be about 90 degrees.
For a cup of water you need to take a teaspoon of tea leaves.
Pour in tea leaves a small amount hot water and after a few seconds drain this water. After this, finally brew the tea. This is what tea experts do in China, Morocco, and Japan. By doing this we reduce the amount of caffeine in the drink and disinfect the tea leaves.
Do not brew the drink for too long, 1-2 minutes is enough, after which you can brew the leaves twice more, each time increasing the brewing time by a minute.
Store tea in a glass or ceramic container with a ground-in lid, as it is hygroscopic, that is, it absorbs moisture, which will negatively affect its quality.

Very often questions arise about green tea, since conflicting opinions can be found both in the press and on the Internet. Here are the main ones:

Does green tea invigorate or calm?

Very weak, repeatedly brewed tea is practically devoid of caffeine, so it may have a calming effect. But a full-fledged, properly brewed drink invigorates, as it contains caffeine.

Does green tea weaken or strengthen?

This question is also often asked by people. But the fact is that green tea does not act so uniformly, it has neither a laxative nor a constipating effect, but will be useful for both diarrhea and constipation, since the substances included in its composition regulate digestion.

Is it possible to drink green tea every day?

There can be only one answer here - the drink can be drunk every day in the absence of contraindications, but no more than 2 cups.

Harm of green tea and contraindications

All of the above applies only to moderate consumption of good green tea; only in this case can we talk about its benefits. If you drink it too often and too much, you can get harm instead of benefit.
