How does Pu'er tea achieve both refreshing and calming effects?

Summer is here. Under the scorching sun, we often feel tired. In the long run, it will inevitably affect the learning efficiency of students and the work efficiency of workers.

Therefore, necessary refreshing has become a part that everyone has to consider. Many times people will choose coffee to achieve the purpose of short-term improvement.

Over the years, tea has also become the choice of more friends.

Today, most families and offices always have some tea, which also has the effect of refreshing, but the negative effects are minimized (of course, this requires us to drink the right amount at the right time).

Especially Pu'er tea, it magically achieves both refreshing and calming effects.

A pair of seemingly contradictory concepts, how does Pu'er tea achieve it?

• The secret of refreshing is caffeine

The principle of Pu'er tea refreshing is actually a little similar to the reason why coffee refreshes. They both contain caffeine, which can stimulate the nerve center, thereby driving away sleepiness and making people excited.

Generally speaking, compared with the fermented cooked tea, raw tea retains more caffeine, so its refreshing effect will be relatively more obvious.

But this does not mean that cooked tea does not have the function of refreshing. In fact, even cooked tea contains caffeine, but its activity is much lower than that of raw tea.

And old tea also contains caffeine, and its activity is also lower than that of new tea. Therefore, it is better to understand that any tea generally contains caffeine, so they generally have a refreshing effect, and Pu'er tea is of course no exception.

• The key to calming the nerves is theanine

If it only contains caffeine, then the effect of tea will not be worse than that of coffee. The wonderful thing is that tea has theanine that coffee does not have, and this is a natural sedative.

Excellent tea often contains 26 kinds of amino acids, and theanine is the highest and most special one among them. It has a calming effect, which can enhance attention and make people concentrate.

In addition, there is a big treasure in tea, which is tea polyphenols.

We often say that tea has anti-aging effects, and the credit behind this is tea polyphenols. Tea polyphenols have a strong antioxidant effect, can remove free radicals, protect human cells from damage, and have the city of human preservatives.

It is precisely because of the presence of caffeine, theanine, and tea polyphenols that tea is a comprehensive health helper.

• Pu'er tea even has the effect of helping sleep

Don't rush to refute it. The sleep-aiding effect mentioned here is of course not raw tea, but cooked tea. You must know that cooked tea is fermented in piles, so the caffeine in the tea leaves reacts with tea polyphenols during fermentation, which reduces the caffeine content and weakens the refreshing effect. At this time, the bitterness of cooked tea is lower than that of raw tea, and it is naturally mellow and sweet, which is the best choice for helping sleep and calming the mind.

Correspondingly, the study also shows that after three minutes of brewing tea, the tea polyphenols in the tea leaves begin to dissolve into the water one after another, thereby offsetting the effect of caffeine and no longer making people excited.

Therefore, during a lunch break or a night of sleep, it is best to pour out the first brew of tea that has been brewed for 3 minutes, and drink the brewed tea again. This will not affect sleep, but will help you sleep.

From the perspective of international balanced nutrition, the composition of tea is the most reasonable, and it can play a balancing role in the coordination of nutrition and metabolism of the human body. The substances contained in tea each play a unique role, and together constitute the energy of a cup of tea.
