Does black tea affect sleep?

We all know that if we drink a lot of tea when we go to bed at night, it will affect our normal sleep, because most teas contain ingredients that can affect brain activity. Among them, black tea is a kind of tea that can affect people's normal sleep. However, many people are not clear about the reason why black tea affects sleep, and do not know whether it will really affect sleep. So, does black tea affect sleep?

First, does black tea affect sleep? The caffeine, vitamins, amino acids, phospholipids, etc. in black tea help the human body digest and regulate fat metabolism. The stimulating effect of caffeine can increase the secretion of gastric juice, thereby increasing appetite and aiding digestion. Compared with black tea and green tea, the content of caffeine and tea polyphenols in black tea is significantly lower. It does not have a refreshing effect and will not make people excited and insomniac. Therefore, drinking black tea at night will not affect sleep like other teas.

Second, some people believe that overnight tea has "poisonous smell", that is because the tea has gone bad, but Pu'er tea contains antioxidant tea polyphenols and other substances, the deterioration (oxidation process) of the tea soup is limited, and it has the effect of natural preservation. After the Pu'er tea is boiled, the fermentation process of the tea essence continues in the soup. Therefore, not only can Pu'er tea be drunk overnight, but the tea soup will also be more red and the tea flavor will be purer and sweeter.

Does black tea affect sleep? It is common knowledge that drinking tea can make people excited and refresh their spirits. Because ordinary tea contains high levels of caffeine, which affects sleep. However, due to the production process of Pu'er tea, caffeine has gradually decayed during the long-term pile fermentation process, while theanine, which has the effect of calming the mind and protecting brain nerve cells, has been preserved. Therefore, drinking Pu'er tea does not affect sleep, but can improve sleep quality. Long-term drinking can even prevent insomnia, neurasthenia, etc. Black tea can accommodate almost all the seasonings you like. You can add milk, sugar, salt, ghee, sesame, peanuts, etc. according to your preferences. Foreigners like to add spices, coffee, cocoa, chocolate, honey, fruits, etc. If you try other types of tea with the same seasoning as black tea, you will immediately understand the taste of black tea and its infinite charm.
