Tea's way of keeping healthy

In China, people regard tea as a kind of culture, because it is deeply rooted in the history of China for thousands of years. China people's research on tea has been handed down, and almost all uses of tea have been explored. Let me introduce you to the way of tea health preservation, I hope it will be useful to you!

As we all know, China has the custom of drinking tea since ancient times, and tea has many benefits. Tea contains more than 600 kinds of chemical components, which not only has the effects of health preservation, health care, beauty and weight loss, but also can prevent and treat some diseases and alleviate the pain suffered by our bodies.

However, many people have misunderstandings about tea, which will bring certain hidden dangers to health, especially the elderly. Do I have to follow the tea? Morning, less, light and warmth? These four principles, in order to make the body healthy, will not affect the body.

(early) morning

Drinking tea in the morning is the best. Because after a day and a night of metabolism, the human body consumes a lot of water and has a high blood concentration. Drinking a cup of light tea can not only replenish water, but also dilute blood and prevent gastric mucosal damage; Especially for the elderly, drinking a cup of light tea after getting up early is very beneficial to the body.

Because the caffeine rich in tea has an exciting effect, and this effect will last for a period of time, if you drink tea in the afternoon or evening, it will definitely cause insomnia at night and have a certain impact on your body, especially the newly picked green tea, which has a strong exciting effect.

Very few

It is best to drink a small amount of tea. A large amount of fluid entering blood vessels itself will increase the burden on the heart. In addition, caffeine and theophylline in tea are stimulants, which can make the human heart beat faster and blood pressure rise. If you drink a lot of tea, you will have discomfort symptoms such as chest tightness and palpitation, which may easily lead to diseases such as heart failure; In addition, drinking a lot of tea will dilute gastric juice and reduce its concentration, leading to symptoms such as indigestion, abdominal distension and abdominal pain, especially for the elderly with duodenal ulcer.

light

Light is the best way to drink tea. Tea contains tannic acid, which can react with iron in food to form new insoluble substances. When the human body drinks a lot of strong tea, the combination of tannic acid and iron will be more active, which will hinder the absorption of iron by the human body, and the elderly will have iron deficiency anemia after drinking strong tea; In addition, tannic acid can combine with protein in food to produce a large amount of tannic acid protein, which is difficult to digest and absorb, especially constipation in the elderly, which will not only aggravate constipation symptoms, but also have an impact on the health of the elderly.

temperature

Warm tea is the best way to drink tea. Relevant experiments have proved that drinking warm tea can make people healthy? Anger? Dripping due to cold tea, discharged with urine; Don't drink herbal tea and overheated tea, because drinking herbal tea can not only clear fire and resolve phlegm, but also have side effects such as strengthening the spleen and nourishing the stomach, resolving phlegm and stagnation; Drinking overheated and scalded tea will strongly stimulate the throat, esophagus and stomach, and may also cause mucosal lesions in these organs.

The nutritional value of tea soup will also be greatly reduced because of the reduction of vitamin C, vitamin P and amino acids in tea due to oxidation. At the same time, because the tea soup has been put on hold for a long time and is polluted by the surrounding environment, there are many microorganisms (bacteria and actinomycetes) in the tea soup, which is very unsanitary.
