What could be nicer than a cup of hot tea on a cold day? For most people, tea is one of the most harmless drinks, which, in addition to comfort, brings a lot of benefits. Part of this information is correct, but still not completely. There are people for whom tea can do more harm than good. Let's see who these people are and for what reason it is contraindicated for them to drink tea.
Despite the long list of benefits, including a tonic effect, tea can affect the body in different ways, especially when it comes to certain health problems.
For example, patients diagnosed with peptic ulcer should not drink tea, as well as those who have increased acidity. In such cases, people almost always develop heartburn, and the gastrointestinal mucosa is severely irritated. That reason should be enough to eliminate the drink from the daily diet, especially during an exacerbation.
Also, experts advise patients with atherosclerosis and hypertension to give up strong tea. This is due to theophylline and caffeine, which excite the central nervous system. When the cerebral cortex is excited, the blood vessels constrict, which can lead to the formation of blood clots in the brain.
Another group of people who should be careful when drinking tea are people who suffer from insomnia. Sometimes even one cup of tea at night is enough for the brain to start working actively, the pulse to increase, and you cannot fall asleep.
The fact is that a cup of tea contains from 14 to 61 milligrams of caffeine. Of course, it is less than in coffee, but tea is still able to disrupt the body's usual work, lead to insomnia, and then to irritability, loss of strength and mental problems.
People with anemia and iron deficiency should stop drinking tea. The fact is that according to a study by Food Science and Nutrition, tea reduces the absorption of iron by 94%. Therefore, if you are diagnosed with anemia, it is better to refrain from drinking tea, or at least not drink it immediately after a meal.
Those who suffer from urinary tract problems should also limit tea intake, as it is a diuretic drink. As a result, this can lead to dehydration, disruption of the digestive tract, and electrolyte imbalance. And as a result, lethargy, rapid or irregular heartbeat, severe headaches.
Those who suffer from allergies or heart disease should avoid herbal teas, as each plant has its own indications and contraindications. Medicinal herbs and plants, used uncontrollably and in large quantities, can aggravate negative symptoms if a person has certain diseases.
It is generally accepted that hot tea is good for people with a high fever. But this is very far from the truth. British pharmacologists have found that tea not only does not bring health benefits in this situation, but, on the contrary, theophylline, which is especially abundant in green tea, increases body temperature. Theophylline, present in both black and green tea, is also a diuretic and therefore renders any antipyretic drugs ineffective.
Frankly speaking, all of us after 50 years should limit the use of strong tea. At this age, due to the active washing out of calcium, our bones become more fragile, and fluorine, which is abundant in strong tea, accumulates in the bones, making them even more vulnerable. But if you suffer from osteoporosis, then you should refrain from tea even at a younger age.
Important to know! Drinking green tea in large quantities sometimes leads to the formation of kidney stones. Green tea contains a lot of oxalic acid salts. If you drink this drink regularly, salts can accumulate in the body and provoke the formation of kidney or gallstones, and if you already suffer from this disease, drinking green tea can worsen the condition.
The effect of tea on the body of a particular person should be analyzed by a specialist, so it is important to consult a doctor. But even if you do not have serious health problems, do not forget about moderation. No matter how useful tea is, excessive consumption of it means an increased burden on the heart and kidneys.
