Pressure from all sides of the pressure to meet, insomnia is a common phenomenon in the white-collar family, through the introduction of this article, we drink what tea does not affect sleep are understood, the Dragon Boat Festival holiday has begun, friends want to have a good quality sleep may want to try to make a cup of tea, tea before bedtime remember to drink tea light-based.
We must first make it clear that tea also contains caffeine, dry tea, caffeine content is about 2 to 4%, the better the tea, the higher the content. Tea produces caffeine from the beginning of germination, the tea buds and the first leaves have the highest caffeine content, followed by a decreasing order. Caffeine in tea health role is relatively large, the content is just enough to make the brain excitatory effect of vigorous, but also strong heart and blood, and diuretic effect on human physiology, play a certain role in regulating the caffeine content of tea is only half of the coffee, and the excretion of the rapid, in the body of the residual time will not be more than 24 hours.
As early as in the "Shennong Ben Cao" is recorded, "Tantalum taste bitter, drink it to make people benefit from thinking, less sleep," people have this common sense, drinking tea can refresh the brain. People who do not sleep well, the night is usually not recommended to drink tea, while working overtime, you can drink a little bit of tea to keep the spirit of exuberance, here is the role of caffeine. Caffeine is one of the main components of tea, which has the effect of excitation of the nerve center, for the question, the direct question is, why can't you drink green tea at night, then the direct and simple explanation is that tea contains caffeine, which can easily cause insomnia.
But as the subject said, black tea caffeine content is higher than green tea, this is also a fact, has been confirmed by a large number of experiments, at the same time, the caffeine content of Pu'er ripe tea is higher than black tea, then, why do we usually feel that drinking green tea is more refreshing, and drink black tea, ripe Pu and does not affect sleep? The main reason is that the oxidation of tea polyphenols will combine with caffeine and counteract the refreshing effect of caffeine. The higher the degree of oxidation of tea polyphenols, the higher the binding capacity with caffeine.
Green tea is an unfermented tea, which contains tea polyphenols that are not oxidized, so the combination of tea polyphenols and caffeine in the brewed green tea broth is only very small. Therefore, the caffeine will also play a significant refreshing effect, while the black tea fermentation degree is very high, its tea polyphenol oxidation degree is very high, therefore, black tea tea tea soup in the tea polyphenol oxides, that is, the theobromine or theaflavin, and the caffeine a large number of binding reaction, the formation of precipitation, offset the caffeine's refreshing effect. This is also why the good black tea tea broth after a while, will become cloudy, the formation of cold after the phenomenon of muddy.
Especially Yunnan large-leafed black tea, tea polyphenol content in tea green is high, after processing the theaflavin, theaflavin content is also correspondingly high, it is more likely to form a cold after the phenomenon of muddy. The higher the quality of yunnan black tea, cold after muddy phenomenon is more obvious, in our life, there are usually some irrational tea drinking phenomenon, for example, a large number of drinking high-fluoride tea, some patients, tea and some drugs to drink together, and some food to eat together, etc., even if the caffeine on the body to help, irrational tea, coffee minus also play a role in jeopardizing the health of the role of the caffeine, such as caffeine will induce excessive secretion of acid in the stomach.
For tea lovers with gastritis, generally can not drink too strong tea; and serious heart disease, as well as neurasthenia, we should also avoid drinking strong tea or drink too much tea, do not drink tea at night.
