People often say that "tea is a medicine for all diseases", and its health effects can be seen. However, even if it is ginseng antler, if it is used improperly, it will not only have no effect on health, but it will cause harm to the body.
I believe that many tea friends like to drink strong tea, a pot of tea, tea accounted for half, but in fact, drinking tea is very harmful to the body.
So how do you define strong tea?
To be correct, the amount of tea, the long brewing time, and the bitter taste are the standards of strong tea.
What harm does the body have on the body? Let Mrs. Chen take you to check it out.

First, strong tea hurts the kidney
Strong tea contains more fluorine than light tea, and the kidney is the main organ for excretion of fluorine. When the fluoride ingested by the human body exceeds the excretion capacity of the kidney, fluoride will deposit in the kidney, resulting in "tea-type fluorosis". .
The strong tea also contains a large amount of oxalic acid, which easily forms calcium oxalate stones in the urethra, which in turn causes kidney stones. Moreover, drinking too much tea can lead to frequent urination and increase the burden on the kidneys.
The rumors that many people believe that "dense tea hangover" is actually not the case. Although theophylline affects the discharge of acetaldehyde from the kidneys, a large amount of acetaldehyde can pass through the kidneys, causing great damage to the kidneys, but the so-called hangover is due to the concentration. Tea stimulates the nerve center and leads to mental activity.
Second, strong tea hurts the stomach
Due to excessive caffeine and theophylline content in strong tea, it stimulates the stomach wall to cause excessive gastric acid. Over time, the gastric mucosa gradually damages, leading to symptoms such as congestion, inflammation and even gastric ulcer, and it will affect the health of the intestines. A lot of caffeine in strong tea is also very addictive, leading to a vicious circle.
Third, strong tea hurts bone
A large amount of caffeine in strong tea will inhibit the absorption of calcium in the duodenum, and will also accelerate the excretion of calcium in the urine. Under the dual action, a large amount of calcium in the body is lost, which may lead to loose bone and prone to fracture. According to the survey, drinking more than five cups of tea a day is easier than 16% higher than that of not drinking strong tea.
Fourth, strong tea wound blood vessels
The caffeine actives in strong tea can cause mental excitement, restlessness, palpitations and other symptoms, leading to increased blood pressure, rapid heartbeat and even arrhythmia, tachycardia and other symptoms, and this is a coronary heart disease patient with tachycardia and atrial fibrillation. It is extremely threatening.
Drinking strong tea also increases blood volume, burdens the heart and exacerbates the symptoms of heart failure, which is sometimes fatal for cardiovascular and cerebrovascular patients.
Five, strong tea hurts
The caffeine in strong tea can cause excessive nerve excitement and easily lead to insomnia, which is harmful to the spirit, especially for mental workers or people with unstable mental states.

However, strong tea is not a harm but not a benefit. A small amount of drinking tea can clear away heat and detoxification, especially those who are addicted to cigarettes, and can clean the lungs to a certain extent. Strong tea also has the effect of eliminating food, greasy, anti-inflammatory and bactericidal, but it is still not suitable for long-term drinking.
Although occasionally drinking some strong tea will not cause serious problems, but people with the following symptoms are strictly forbidden to drink strong tea, not only will cause great harm to the body, and even die.
First, stomach ulcers
Excessive caffeine and theophylline content in strong tea will stimulate the stomach wall to cause a large amount of gastric acid secretion, which will affect the healing of the wound, and will also reduce the efficacy of the stomach medicine, which is not conducive to the recovery of the body.
Second, arrhythmia
Theophylline and caffeine in tea have a strong excitatory effect on the central nervous system, which can cause symptoms such as rapid heartbeat, tachycardia and even palpitations. It is a great threat to patients with cardiovascular and cerebrovascular arteriosclerosis and will increase the heart. Burden, speed up heart failure.
Third, hyperthyroidism
A large amount of caffeine in strong tea will accelerate the metabolism of hyperthyroidism patients, which will increase the consumption of various nutrients, which will lead to aggravation of the disease.
Fourth, glaucoma
Strong tea will cause irritation to the nervous system, and the intraocular pressure will increase. In severe cases, the eyes will become more congested and even glaucoma will be acute.
Five, gout
Terpenoids in tea can cause gout. You should choose to drink a small amount of light tea after an hour of dining.
Six, kidney stones
Tannin in tea promotes the formation of stones and has a greater impact on the prevention and control of kidney stones.
Seven, constipation
The tannic acid in the tea will reduce the effect of the intestinal mucosal secretion, reduce the secretion of intestinal juice, and can not lubricate the intestinal tract. The feces stay in the intestine for a long time, and the intestinal wall absorbs too much water from the feces, causing the stool to be dry and difficult to discharge.
Eight, women in menstruation, pregnancy, childbirth, lactation
Excessive blood loss during menstruation, drinking strong tea is not conducive to the absorption of iron, can lead to anemia, and caffeine can also stimulate the body, leading to menstrual pain and prolonged menstruation.
Drinking strong tea during pregnancy is not conducive to the absorption of nutrients, but also easy to lead to anemia, and caffeine will increase the number of fetal movements, and even lead to fetal dysplasia.
Drinking strong tea during the delivery period will affect the rest of the spirit, which will lead to insufficient physical energy during childbirth and weak uterine contractions, which may lead to dystocia.
The tannic acid in strong tea will inhibit breast lactation and reduce the amount of breastfeeding, and caffeine will increase the milk to cause the baby to be excited and uneasy, affecting the child's development.
"04"
Everything has its advantages and disadvantages. However, in the case of drinking strong tea, it is obviously more harmful than good. I hope that everyone can drink tea scientifically and drink tea reasonably, and drink the tea they love to drink without prejudice to their health.
