Tea cannot be drunk overnight.

1. Tea contains tea polyphenols, vitamins, catechins, amino acids and other components, antioxidant is one of the important effects of tea, tea exposed to the air for a long time, vitamin C, etc. are oxidized, tea polyphenols are oxidized into tea pigments, and the antioxidant effect will be weakened, especially green tea and white tea.

2. After the tea is left for a long time, tannic acid will be produced, and the tannic acid will be completely dissolved in the tea. After drinking in the morning, and then eating breakfast, tannic acid will interact with food to produce oxalic acid, and tannic acid and oxalic acid combine to cause chemical changes, which is easy to produce stones. At the same time, tannic acid also makes other nutrients more difficult to digest.

3. If the overnight tea is left for more than 24 hours, because the tea itself contains sugar and a small amount of protein, it will become moldy under suitable temperature and humidity conditions, produce bacteria and mold, and cause diarrhea. Therefore, tea that has been more than 24 hours old should not be drunk, especially in the summer when the temperature is high.

You can make tea before going to bed at night, and drink it the next day, the tea has not deteriorated, and of course there is no problem with drinking. If the tea leaves are steeped for too long, especially if the temperature is high, it will lose its green color and increase the degree of yellowness. This is the oxidation product of the oxidation of tea polyphenols in tea to form yellow-red and reddish-brown, mainly theaflavin, thearubigin, theabrownin, etc.

These products are non-toxic and do not cause harm to the human body. This change is day and night, and the temperature is higher during the day, and the change is a little bigger. But if the tea is soaked for too long, bacteria will breed and deteriorate, of course, you can't drink it, and it doesn't matter if you drink it for no more than 24 hours.

Overnight tea generally refers to the tea soup brewed in the afternoon or evening of the first day and put it on the next morning, and the time passes through one night, which is called overnight tea. In the past, it was said that drinking overnight tea caused cancer, and experts in China's food industry gave a conclusion as early as the 80s that it would not cause cancer.

Normally, overnight tea can be used to rinse your mouth or take a few sips to moisten your throat the next morning, which is also the result of the practice of the older generation of tea drinkers. However, from the perspective of nutrition and hygiene, if the tea soup is left for a long time, the vitamin C and other nutrients in the tea soup will be reduced due to gradual oxidation, and the taste will become bland. In addition, especially in summer, at high temperatures, placed for a long time, the proteins and sugars in the tea are the medium of bacteria and molds, which are easy to breed molds and bacteria, resulting in the deterioration and corruption of the tea soup, and the spoiled tea soup cannot be drunk.

Generally speaking, from the perspective of nutrition or tasting, no matter what kind of tea, the brewing and drinking of tea should be brewed and drunk at any time. Fresh overnight tea can be used to cough or drink a few sips, but there is no nutrition and taste at all, and it should not be brewed again, and the proverb says: "Tea can be drunk more, not more brewing".

Overnight tea due to too long, most of the vitamins have been lost, the old container is not well sealed will cause poisonous insects to fall in or crawl over, and the soup protein, sugar, etc. become the nutrients for bacteria and mold to multiply, so it is not suitable to drink.
