How is the dry throat after drinking tea?

After drinking tea, I sometimes feel dry in my mouth, like eating an unripe banana, and my tongue is dry and a little numb. Some people describe this feeling as thirst, while others say it is astringent. Why?

Where does astringency come from?

The astringent substances of tea mainly include tea polyphenols, aldehydes, iron and other substances, among which catechins are particularly important. Lipid catechins taste bitter, and the content in bud leaves is much higher than that in coarse old leaves. In general, the bitterness of young tea with one bud, one leaf or two leaves is much stronger than that of tea with three leaves or four leaves.

If you drink green tea, you will feel astringent, but if you drink cooked tea and old white tea, you will feel less astringent.

Six causes of dry throat after drinking tea

The main reasons are the high content of tea polyphenols, too strong tea, too much tea at one time, the fire of tea has not been finished, the quality of tea is not up to standard, and diuresis after drinking tea.

Six causes of dry throat after drinking tea

㈠

High content of tea polyphenols

Tea polyphenols are the "culprit" behind dry mouth, and the reaction between catechin and mucin in saliva can also cause dry mouth.

Mucin is a lubricant for the mouth and throat. When catechin meets it, it combines with it through the interaction of hydrophobic bond and hydrogen bond, which leads to dehydration of protein and loss of lubrication of mouth and throat.

Then there will be a feeling of dryness.

This Chata is strong.

All major teas have different tea ratio standards and different brewing methods. If you put too much Chata, or sit in a cup for too long, resulting in too strong tea soup, you will feel dry throat, bitter mouth and "locked throat".

For green tea rich in tea polyphenols, if the tea soup is too strong, the dryness will be more obvious.

Excessive drinking tea at one time.

Drinking tea is not like drinking water. You can swallow it. If you drink a lot of tea at one time, it will reduce the osmotic pressure inside and outside human cells, dilute blood and unbalance electrolytes.

At this time, in order to protect itself, the body will discharge the water in the cells, which will lead to a temporary increase in osmotic pressure in the paper cells, and then produce dry mouth symptoms.

The tea is not finished yet.

Wuyi rock tea has a process of cultivating fire. The tea has just been cultivated, and the anger has not gone away. Drinking it at this time will easily lead to excessive internal heat, and the tongue and throat will be very dry, resulting in a dry feeling.

This feeling of dryness is similar to thirst, so it is often mistaken for thirst.

Except for rock tea, freshly dried green tea and freshly squeezed raw tea, they are all suitable for drinking after annealing.

The quality of tea is not up to standard.

Such as high temperature baking, improper drying, improper stacking, etc. Tea cake, Tuo tea and brick tea all have a certain thickness. When they are dried, they may be unevenly lost due to external moisture. It's dry outside, but there's a lot of moisture inside. In the later Chen Fang process, the tea cake may be moldy, resulting in the tea cake being fragile or cracked. There are also some tea leaves, which are rapidly oxidized due to improper storage, rot and mildew, or stored in a closed environment with high temperature and high humidity.

After drinking this tea, the throat will feel dry, hard to swallow and tight and itchy.

Drinking tea and diuresis

Tea has diuretic effect, which is the biggest reason why drinking tea will make you feel more thirsty.

Studies have shown that compared with drinking water, the amount of urination when drinking tea is 1.5 times more. Therefore, when you feel thirsty, if you want to quench your thirst with tea, the more you drink, the more thirsty you are.

Because the oral cavity and digestive tract are stimulated by tea, metabolism occurs and urination occurs at the same time. Therefore, when you are thirsty, you should drink water first, replenish water in your body and then drink tea.
