Under normal circumstances, overnight tea refers to tea soup that has been stored for more than 8 hours. This tea soup will turn reddish brown during the storage process. The key point is that the tea polyphenols rich in tea collide with oxygen in the air and react with each other, causing a lot of tea pigments to appear and turn the tea soup into reddish brown.

What are the functions and benefits of overnight tea?

First, it can help oxidation resistance.

When tea soup is discarded, a lot of tea pigments will be formed. Tea pigments can improve the antioxidant substances of the body after entering the body, thus playing a practical role in preventing the formation of carcinogens. Therefore, drinking some overnight tea in daily life can effectively play an antioxidant role.

Second, help get rid of bad breath

Although overnight tea will change in the long-term storage process, the essential oil contained in it is impossible to fade. Therefore, gargling with overnight tea every morning can have the practical effect of eliminating bad breath, and overnight tea can also help inhibit bacteria in the oral cavity, so that bacteria can not multiply and cause bad breath to appear constantly.

Third, get rid of the fishy smell

Cleaning some plates for storing fish or meat with overnight tea can quickly remove the fishy smell left on the plates, make the plates clean while leaving a faint tea smell, or use overnight tea to clean your hands and help clean the grease on your hands when you feel greasy.

It can be seen from here that overnight tea has certain benefits and functions, but although overnight tea has benefits and functions, you should try to drink fresh brewed tea as much as possible in normal times, and pay attention to some matters of drinking tea at that time. People who like to drink tea should choose according to their own health at that time. If they feel that they have symptoms such as dry mouth, bitter taste and excessive internal heat, they can drink green tea moderately, while those who are slightly cold should drink semi-fermented oolong tea. At the same time, it is necessary to pay attention not to drink too strong tea in normal times, especially after meals, which will affect digestion and absorption, especially those who suffer from stomach diseases. In normal times, they should stay away from tea soup as much as possible.
