Five myths about drinking tea that cannot be ignored, severe cases can be fatal

In daily life, many people are used to giving strong tea to someone who is drunk to sober them up, and some people believe that tea can cure "all diseases" and can be drunk without any scruples... But today we want to tell you that all of this is bad for your health and is a misunderstanding about drinking tea.

Myth one: Strong tea sobers you up. Some people believe that drinking strong tea after alcohol has a "sobering" effect, but this is wrong. After drinking alcohol, the ethanol in the liquor enters the bloodstream through the gastrointestinal tract, is first converted into acetaldehyde in the liver, then into acetic acid, and then breaks down into carbon dioxide and water that are excreted from the body through the kidneys. But if you drink strong tea after alcohol, the caffeine in the tea can quickly exert a diuretic effect, thereby promoting acetaldehyde (a substance with a relatively strong stimulating effect on the kidneys) that has not yet been broken down into acetic acid to enter the kidneys prematurely, damaging the kidneys.

Myth two: Tasting new tea is refreshing and delightful. New tea refers to tea picked less than one month ago. This kind of tea is excellent in shape, color and taste, and drinking it is indeed a pleasure. However, because the tea has been stored for too short a time, it contains more polyphenols, alcohols and aldehydes. If you drink new tea for a long time, symptoms such as abdominal pain and bloating may occur. At the same time, new tea also contains relatively active tannic acid, caffeine and so on. Excessive drinking will make the nervous system highly excited, producing "tea drunkenness" symptoms such as weakness in the limbs, cold sweat and insomnia.

Myth three: Drinking tea will raise blood pressure. Tea has effects such as anticoagulation, promoting dissolution, inhibiting platelet aggregation and regulating blood lipids. It can prevent cholesterol and other lipid masses from depositing on blood vessel walls, thereby preventing coronary arteries from narrowing. In particular, tea contains catechins, which can reduce the cholesterol content in the human body, and blood lipids also decrease accordingly, thereby lowering blood pressure. Therefore, drinking tea can prevent and treat cardiovascular diseases.

Myth four: Tea cures all diseases. Some people believe that tea is not only a safe beverage, but also a good medicine for treating diseases. Little do they know that for some patients, it is not suitable to drink tea, especially strong tea. The caffeine in strong tea can make people excited, cause insomnia and increase the metabolic rate, which is not conducive to rest; it can also speed up the heartbeat of patients with high blood pressure, coronary heart disease and kidney disease, and even cause arrhythmia and frequent urination, increasing the burden on the heart and kidneys. In addition, caffeine can also stimulate gastrointestinal secretion, which is not conducive to the healing of ulcers; and the tannins in tea have an astringent effect, slowing intestinal peristalsis and worsening constipation.

Myth five: Chewing tea roots is good for health. Many people believe that chewing tea roots can help remove bad breath in the mouth, so after drinking tea they like to chew the tea roots. Although this itself cannot be considered a bad habit, some tea roots may have pesticide residues, so it is better not to chew tea roots.
