Black Tea is a fully fermented tea, rich in aromatic substances. These aromatic substances, also known as volatile flavor components (VFC), are the general term for the volatile substances in tea. Black tea contains nearly twice as many aromatic substances as Green Tea. These aromatic compounds can soothe the nerves, relax the body, stabilize emotions, and aid in sleep. Therefore, drinking a moderate amount of black tea in the evening can promote better sleep.

However, we need to understand that everyone's constitution is different, so it's not guaranteed that drinking black tea will necessarily help you sleep. It only plays an auxiliary role. Additionally, when drinking black tea in the evening, be sure to pay attention to the quantity. Strong tea should be avoided, and do not drink too late in the evening.

Evening Tea drinking Precautions

Many people enjoy drinking tea. Tea contains numerous elements that can help alleviate fatigue, reduce heat, and provide some nutrients to the body. Some people have the habit of drinking tea in the evening, which can make it difficult to fall asleep. There are certain precautions to take for healthy tea drinking in the evening.

Those who frequently drink tea know that it's not advisable to drink too much tea in the evening, as it can make it hard to fall asleep. This is related to the stimulating effect of tea. Therefore, when drinking tea in the evening, it's important to choose the right type of tea and the time of consumption to maintain good health. Let's look at the precautions for evening tea drinking.

As people become more dependent on tea, many friends also drink tea during their rest periods in the evening. Experts suggest that drinking tea in the evening can be beneficial to your health, but timing is crucial to avoid disrupting sleep.

Afterward, the polyphenols in the tea gradually dissolve into the water, counteracting the effects of Caffeine, making it less likely to cause significant physiological excitement. Thus, if you discard the first infusion after about three minutes and refill with hot water, the stimulating effect won't be as pronounced.

For those who like to drink tea in the evening, it's recommended to opt for black tea. Green tea is an unfermented tea with a higher content of polyphenols that retain their original properties, making it more stimulating. Black tea, on the other hand, is a fully fermented tea with fewer polyphenols. After undergoing a “ripening” process, its stimulating effects are milder, making it suitable for evening consumption. For individuals with weak spleen and stomach, adding milk to black tea can warm the stomach and promote sleep.

Tea drinkers are aware that tea has a stimulating effect and should be consumed sparingly in the evening to avoid insomnia. However, this overlooks the dual nature of tea, both red and green, which can have both stimulating and soothing effects on the brain, making it more alert or aiding in sleep. The key lies in how and when you drink it, as different methods and timings can produce different outcomes.

The caffeine and polyphenols in tea have a significant impact on the brain's nervous system. When tea is steeped for about 3 minutes, approximately 70% to 80% of the caffeine dissolves in the water, giving the tea a noticeable stimulating effect that can make you feel more awake.
