How to drink tea is healthy?
1, drink tea and see the status.
Tea is a good thing, but you have to look at your state before drinking tea. For example, you just went to a hotel and got as drunk as a fiddler, and you want to have tea immediately after you get home. Moreover, this drunken state is not the right time to drink tea, and drinking tea after drinking is easy to hurt the kidney. Many people think that tea can relieve alcoholism, but it is not. There is a lot of theophylline in tea, which has an exciting effect. Originally, people were in a state of excitement after drinking wine. Drinking tea at this time is equivalent to adding fuel to the fire. In addition, theophylline has diuretic effect, which will promote acetaldehyde to enter the kidney, increase the burden on human organs, and have adverse effects on renal function.
Don't drink tea on an empty stomach except after drinking. As mentioned earlier, tea contains theophylline. If you drink tea on an empty stomach, theophylline will not touch the "food in the stomach" but directly touch the gastric juice, but react. Theophylline easily irritates the stomach and causes indigestion caused by gastric acid.
You can't drink tea immediately after a big meal, because you are afraid of affecting your gastrointestinal work. If you have a cold and a fever, you can't drink tea at this time, especially you can't take medicine with tea as boiling water. Don't drink tea before going to bed, especially strong tea. I can't sleep if I drink too much. If a female friend is in menstruation or lactation, then it is not appropriate to drink a lot of tea.
There are also people who are in good health, weak, or have heart disease and poor liver function. Drinking a lot of tea is not recommended for fear of increasing the burden. In short, think about your state before drinking tea. If you feel uncomfortable, drink it another day, and drink it next time. No matter how much you like tea, don't force it.
2, drink tea to see the season
Drinking tea can be linked to the season, or you can watch the season to drink tea. The most widely known thing is to drink more green tea in summer and some black tea and old white tea in winter. This is because it is very hot in summer, and we will sweat easily, so we should drink tea in time to replenish water. Green tea is cold, especially suitable for drinking in hot summer, clearing away heat and relieving summer heat. Black tea and old white tea are warm. Drinking them in cold winter can warm the heart and stomach, keep warm and keep out the cold.
In addition, you can drink scented tea and white tea in spring and oolong tea in autumn. White tea is a micro-fermented tea, which is not fried or kneaded, with natural technology and light taste. Moreover, scented tea is fragrant, refreshing and comfortable, and drinking scented tea in spring is a kind of enjoyment. Oolong tea is semi-fermented, neither hot nor cold, mostly neutral tea. It has a strong aroma and a unique taste, with both the fragrance of green tea and the mellow fragrance of black tea. Like the dry climate in autumn, we often feel thirsty and our lips are dry, so we wear lip balm in autumn. Oolong tea, for example, has the effect of moistening skin and throat. It is appropriate to drink oolong tea in autumn.
3, drink tea to see physical fitness
Constitution is a concept of TCM theory, and there are about nine basic constitution types, namely, peace, qi deficiency, yang deficiency, yin deficiency, phlegm-dampness, damp-heat, blood stasis, qi stagnation and internal quality. It is normal to have a peaceful constitution, while people with qi deficiency tend to be weak in limbs, people with yin deficiency are afraid of heat, people with yang deficiency are easy to be afraid of cold, people with damp heat are easy to get oil, people with qi stagnation are easy to lose sleep, people with phlegm dampness are easy to get fat, and people with blood stasis are forgetful and allergic.
Therefore, depressed people should not drink tea before going to bed, which is easy to lose sleep, and it is more difficult to fall asleep after drinking tea. There are also people with qi deficiency who are weak and should not drink a lot of tea, especially strong tea. Caffeine in tea has the function of exciting nerves, which is easy to increase the burden on the body. There are also people with yang deficiency and phlegm dampness, and people with poor spleen and stomach should not drink a lot of tea. What is said here is that it is not advisable to drink a lot of tea. It is natural to drink tea.
4, drink tea to see the age
Drink tea to see your age. Old people are suitable for drinking scented tea, black tea and old white tea, while young people are suitable for drinking green tea, white tea and oolong tea. Because the elderly are old, their physical functions are not the same as before, and they can't accept herbal tea, so they are suitable for drinking warm tea, while young people are in good health and can basically drink any kind of tea. Green tea is fresh and refreshing, has a strong sense of convergence, and is more appetizing for young people.
How about strong tea?
Actually, there is no specific answer. For example, if you only drink one cup of strong tea and seven or eight cups of weak tea a day, as long as the tea contains similar substances, the impact on your body is similar. It's not that light tea is necessarily good, but strong tea is definitely bad for your health. The key is quantity. If it's just a cup, in fact, strong tea won't bring too much harm to the body, so don't worry too much.
But if a person drinks a lot of strong tea for a long time, his body will be affected by the following:
1, affecting blood
If a person drinks a lot of strong tea for a long time, it will increase the caffeine content in the body and affect the secretion of insulin. After hypoglycemia, there will be discomfort symptoms such as dizziness, weakness and palpitation, and may also cause blood pressure to rise.
If strong tea is absorbed into the blood, it will cause the blood to become sticky and affect the blood circulation of the whole body. After the heart is overloaded, symptoms such as chest tightness and arrhythmia will appear. In particular, patients with heart disease can't drink strong tea, so as not to cause the heartbeat to accelerate, which is not conducive to the control of the disease.
2, affecting the stomach.
After eating food, people need to digest it through the stomach, which contains a lot of gastric acid, which mainly plays the role of corroding food and makes it quickly digested and absorbed. If you drink a lot of strong tea for a long time, the gastric juice will be diluted, and after the concentration of gastric juice drops, you can't digest food smoothly, causing indigestion, abdominal distension and abdominal pain, and even gastric ulcer in severe cases.
3, affect the absorption of iron nutrition.
Tea contains tannins. If you drink a lot of strong tea for a long time, you will consume too much tannin. These tannins will react with iron in the human body, making it impossible for people to absorb iron nutrition smoothly. After the number of red blood cells in the body drops, it will cause iron deficiency anemia, causing dizziness, yellow face, weakness, poor breathing and other symptoms.
4, affecting defecation
Moderate consumption of strong tea can help people detoxify, but a large amount of strong tea will lead to excessive intake of tannic acid, which will combine with protein to form insoluble substances, making it impossible for people to absorb protein smoothly and increase the burden on the intestines.
At the same time, excessive intake of tea polyphenols will also cause excessive convergence of gastrointestinal mucosa, slow down gastrointestinal peristalsis and cause constipation. Long-term constipation can cause toxins in the body not to be discharged smoothly, which is easy to cause intestinal diseases.
5, affect the bones
Strong tea contains a lot of caffeine. Excessive caffeine intake will affect the absorption of calcium nutrition in duodenum, and also cause a large amount of calcium to be excreted with urine. If the human body can't absorb enough calcium nutrition, the body will actively mobilize bone calcium to maintain the body's function. If it goes on for a long time, it will be prone to osteoporosis, and if it is not careful, it may also cause fractures.
6, affecting sleep
Drinking a lot of strong tea for a long time will lead to excessive caffeine intake in the body and strong excitement in the central nervous system of the human body, especially when sleeping at night. Drinking a lot of strong tea will make the brain in an overexcited state, which will make people unable to sleep smoothly for a long time. Even if the brain is still active during light sleep, it will also reduce the quality of sleep. After a long time, people's immunity will also decline.
Tips for drinking tea:
1, don't drink tea when you are very thirsty.
Pay attention to drinking more water in daily life. If you feel very thirsty, it means that your body is already in a state of water shortage. It is not recommended that you throw water on yourself at this time. Although tea has the effect of promoting fluid production and quenching thirst, don't drink tea fiercely at this time.
2. You can't use tea drinks instead of drinking tea.
Many people find it troublesome to make tea and have a false sense of health, so they often drink tea and drinks, such as iced black tea and green plum tea. Bian Xiang Xiao tells you that tea drinks can't replace tea at all. Although these tea drinks are quite enjoyable to drink, they can't completely quench their thirst to a great extent. Moreover, these tea drinks also contain high sugar, which will consume a certain amount of water when they are decomposed in the body, so the more you drink, the more thirsty you are. Patients with diabetes, hypertension and hyperlipidemia should drink less such tea drinks.
3. Wash the teapot in time after drinking tea.
Many people have the bad habit of not cleaning the teapot after drinking tea. Some people use water for drinking tea, the water quality is better, and the tea scale is generally less. Just rinse it. There are some, wait until the next time you want to drink. Either way, it is very undesirable. Tea scale should be cleaned in time, because the nitrite content in it is very high, which is very bad for people's health and will breed a lot of bacteria.
It is recommended to drink black tea after breakfast.
First of all, drinking tea on an empty stomach in the morning is not recommended. After breakfast, tea lovers can drink a cup of black tea, which can improve dehydration at night and reduce the burden on kidneys. It can also regulate the stomach.
The above is some knowledge about drinking tea. In a word, drinking tea itself is good for your health. Whether it is strong tea or weak tea, it is beneficial as long as it is moderate. However, if your daily intake is too high, whether it is strong tea or weak tea, it may cause harm to your body and bring adverse effects to your body. Everyone should pay more attention to this point. It is good for your health to pay too much attention to everything.
