However, we should also pay attention to the following:
1. Tea can be divided into coolness and warmth through different production processes. People with hot and dry constitution should drink herbal tea, while those with deficient and cold constitution should drink warm tea.
It is best to drink black tea at night. Because green tea belongs to non-fermented tea, it has high content of tea polyphenols and strong irritation; Black tea is a kind of completely fermented tea with weak irritation. Especially for people with weak spleen and stomach, adding some milk when drinking black tea can play a certain role in warming the stomach.
People who are usually easily excited or sensitive, have poor sleep and are weak should drink less or not drink tea at night.
4. Drink less tea in the evening, and don't make the tea too strong. It's best to drink after meals. Drinking tea on an empty stomach can easily inhibit the secretion of gastric juice, hinder digestion, and seriously cause palpitations, headaches and other "tea drunkenness" phenomena.
Don't drink tea on an empty stomach, drink tea one hour after meals, and it is best not to drink tea when you have a fever and during the female physiological period.
