Tea contains catechins, cholesterol ketone, caffeine, inositol, folic acid, pantothenic acid and other components, which have the function of preventing and inhibiting obesity under the comprehensive action.

Tea has two functions of "refreshing" and "nourishing" at the same time, which can not only make the brain more awake and flexible, but also restrain the excessive excitement of the brain and make people fall asleep easily. It depends on how you drink tea. In summer, tea is people's favorite drink, but medical experts remind that drinking tea requires a clear understanding of one's physique and proper drinking, otherwise it will easily harm one's health. Traditional Chinese medicine believes that people's physique can be divided into dry heat and deficiency cold, and tea can also be divided into coolness and warmth through different production techniques, so different constitutions also pay attention to drinking tea. People with hot and dry constitution should drink herbal tea, while those with deficient and cold constitution should drink warm tea. When alkali is dissolved in water, tea has obvious refreshing effect and makes people excited. After that, the tea polyphenols in tea gradually dissolve in water, which counteracts the effect of caffeine, so it is not easy to cause obvious physiological excitement. Therefore, when drinking tea at night, as long as you pour out the first tea that has been soaked for about 2 minutes, and then add boiling water to soak it again, the refreshing effect will not be so obvious. It is best to drink black tea at night. Because green tea belongs to non-fermented tea, it has high content of tea polyphenols, maintains its original properties and is irritating; Black tea is a completely fermented tea. Although the content of tea polyphenols is low, it is mild after "aging" and suitable for drinking at night. Especially for people with weak spleen and stomach, adding some milk when drinking black tea can play a certain role in warming the stomach. However, people who are easily excited or sensitive, have poor sleep and are weak should drink less or not drink tea at night. In addition, when drinking tea at night, you should put less tea leaves and don't make the tea too strong. It is best to drink tea after meals, because drinking tea on an empty stomach will harm your health, especially for people who don't drink tea often, it will inhibit the secretion of gastric juice, hinder digestion, and seriously cause palpitations, headaches and other "tea drunk" phenomena.
