Due to the dry weather in autumn, hydrating the body is one of the ways to moisturize dryness, so drinking tea for health preservation is most suitable. Tea leaves not only have effects such as refreshing the mind, clearing heat and relieving summer heat, aiding digestion and resolving phlegm, removing greasiness and weight loss, calming the mind and relieving irritability, detoxifying and sobering up, promoting fluid production and quenching thirst, reducing fire and improving eyesight, stopping dysentery and removing dampness, but also play a positive role in delaying aging and preventing cardiovascular diseases, cancer, and other conditions.

Although it is suitable to drink tea all year round, there are certain considerations for drinking tea in different seasons. For example, green tea is suitable for spring and summer, as it has the effects of clearing heat, relieving summer heat, detoxifying, and quenching thirst; while oolong tea, black tea, and other warm teas are suitable for autumn and winter, as they can aid digestion and are less likely to harm the spleen and stomach. Oolong tea is a semi-fermented tea, including Wulong tea, Tieguanyin, Dahongpao, etc., which falls between black tea and green tea. It can eliminate dryness in the body and achieve the effect of clearing dryness and promoting fluid production; while black tea is a fully fermented tea.

In fact, the most important aspect of drinking tea for health preservation is to drink the tea you like, without being overly constrained by which type of tea is best. However, it must be noted that people who usually have a cold stomach and experience diarrhea after eating something cool should最好不要 drink green tea. Elderly people are advised to use aged raw Pu'er tea, which, like green tea, can also have a good effect on lowering blood lipids. However, semi-fermented, fully fermented, and post-fermented teas such as oolong tea and black tea have effects such as removing stagnation, aiding digestion, and refreshing the mind, making them more suitable for most people.
