Drinking tea is a healthy lifestyle. Brewing a fragrant cup of tea on a tired afternoon, nothing is more refreshing. However, not everyone is suitable for drinking tea. For the following 12 people, drinking tea is equivalent to taking poison.
People of all ages enjoy slowly brewing a pot of tea on weekends to enjoy the leisure of the holiday. However, not everyone is suitable for drinking tea for health preservation. Let's see in which situations we need to stay away from tea.
1. People with a fever should avoid drinking tea. The caffeine in tea can not only raise the body's temperature but also reduce the effectiveness of medication.2. Patients with liver disease should avoid drinking tea. Most substances in tea, such as caffeine, are metabolized by the liver. If the liver is diseased, drinking too much tea beyond the liver's metabolic capacity can damage liver tissue.
3. Patients with neurasthenia should drink tea with caution. The caffeine in tea has a stimulating effect on the central nervous system. Drinking strong tea, especially in the afternoon and evening, can cause insomnia and worsen the condition. They can drink tea once in the morning and once in the afternoon. In the morning, it's advisable to drink scented tea, and in the afternoon, green tea. No tea should be consumed at night. This way, the patient will feel refreshed during the day and calm at night, helping them fall asleep earlier.
4. Pregnant women should avoid drinking tea, especially strong tea. Tea contains a large amount of tea polyphenols and caffeine, which have many unfavorable factors for the growth of the fetus in the mother's womb. In order for the fetus's intelligence to develop normally and to avoid excessive stimulation from caffeine on the fetus, pregnant women should drink little or no tea.
5. Women who are breastfeeding should not drink strong tea. Drinking strong tea during lactation can lead to excessive caffeine entering the breast milk, which can indirectly cause excitement in the infant after feeding, easily leading to less sleep and more crying.
6. Patients with ulcers should drink tea with caution. Tea is a stimulant for gastric acid secretion. Drinking tea can increase the amount of gastric acid secreted, increasing the irritation to the ulcer surface. Regularly drinking strong tea can worsen the condition. However, for mild patients, they can drink some light tea 2 hours after taking medication. Sugar-added black tea or milk-added black tea can help reduce inflammation and protect the gastric mucosa, and also have a certain effect on ulcers. Drinking tea can also block the synthesis of nitroso compounds in the body, preventing precancerous mutations.
7. People with malnutrition should avoid drinking tea. Tea has the function of decomposing fat. For people with malnutrition, drinking tea to decompose fat will make the malnutrition worse.
8. People who are drunk should drink tea with caution. Tea has a stimulating effect on the central nervous system. Drinking strong tea after being drunk will increase the burden on the heart. Drinking tea will also accelerate the diuretic effect, causing the toxic aldehyde in alcohol to be excreted from the kidneys before it is decomposed, which is highly irritating to the kidneys and harmful to health. Therefore, people with heart or kidney disease or poor function should not drink tea, especially not a large amount of strong tea. For healthy people, they can drink a small amount of strong tea. After sobering up, they can eat a large amount of fruit or drink vinegar in small sips to speed up the body's metabolism and relieve drunkenness.
9. Be cautious about taking medicine with tea water. There are many types of drugs with different properties, so whether tea water can be used to take medicine cannot be generalized. The tannins and theophylline in tea can undergo chemical changes with certain drugs. Therefore, when taking hypnotic, sedative drugs, and iron-containing blood tonics, enzyme preparations, and drugs containing protein, it is not advisable to use tea water to take the medicine because tea polyphenols are prone to react with iron agents to form precipitates, which may affect the drug's efficacy.
Some Chinese herbal medicines, such as ephedra, gambir, and coptis, are also not suitable to be mixed with tea water. It is generally believed that it is not advisable to drink tea within 2 hours after taking medication. However, when taking certain types of vitamin drugs, tea water has no effect on the drug's efficacy because the tea polyphenols in tea can promote the accumulation and absorption of vitamin C in the human body. At the same time, tea itself contains various vitamins and has effects such as excitement, diuresis, lowering blood lipids, and lowering blood sugar, which is beneficial to the human body for enhancing drug efficacy and restoring health. In addition, it is commonly believed in folk that it is not advisable to drink tea when taking tonics such as ginseng and deer antler, which also has a certain rationale.
10. Patients with anemia should avoid drinking tea. The tannic acid in tea can combine with iron to form insoluble complexes, making the body unable to get enough iron. Therefore, patients with anemia should not drink tea.
11. Patients with urinary stones should avoid drinking tea. Urinary tract stones are usually calcium oxalate stones. Because tea contains oxalic acid, it can form stones with the calcium excreted in the urine. If patients with urinary stones drink a large amount of tea, it will worsen their condition.
12. Avoid drinking tea on an empty stomach. Drinking tea on an empty stomach can dilute gastric acid, inhibit gastric juice secretion, hinder digestion, and even cause symptoms of "tea intoxication" such as palpitations, headaches, stomach discomfort, dizziness, and irritability. It also affects the absorption of protein and can cause gastritis. If "tea intoxication" occurs, it can be relieved by sucking on candy or drinking some sugar water.
