Drinking tea varies with the seasons, as the saying goes: "Drink green tea in summer, black tea in winter, and oolong tea all year round."

In summer, it is recommended to drink green tea. Green tea is bitter and cold in nature, which can clear heat, relieve summer heat, detoxify, quench thirst, and strengthen the heart. However, for consumers who prefer iced tea drinks, as well as women and those with a cold stomach, oolong tea is a better choice.

The explanation is that green tea is unfermented tea, bitter and cold in nature. Iced green tea is too cold and not suitable for women or those with a cold stomach. Black tea is fully fermented tea, sweet and warm in nature. If consumed in hot weather, it may cause internal heat. Oolong tea, being semi-fermented, falls between the two—neither cold nor hot—and can both reduce heat and relieve thirst while restoring body fluids.

In autumn, the weather is dry, and "the qi of dryness prevails," often causing dry mouth and throat. It is advisable to drink oolong tea, Tieguanyin, and other green teas. Green tea is neutral in nature, between black and green tea, neither cold nor hot, making it suitable for autumn weather. Regular consumption can moisturize the skin, benefit the lungs, generate saliva, soothe the throat, effectively remove residual heat from the body, restore body fluids, and greatly benefit autumn health. Green tea has a golden liquor, plump and evenly shaped leaves, tightly rolled curls, a greenish lustre, rich aroma, and a refreshing, sweet aftertaste.

When the weather is hot and sweating is heavy, tea is rich in potassium. Drinking tea beverages can both replenish water and compensate for the potassium lost through sweat. However, experts remind that consuming large amounts of tea beverages at once is unscientific. The correct method is to drink them in several portions throughout the day, so that the polyphenols and catechins in the tea can be fully absorbed by the body.

In late summer and early autumn, the diet should be light. Greasy foods can be paired with tea, with barley tea and oolong tea being the most suitable. In particular, those who love spicy food can choose different flavors of iced oolong or barley tea to reduce heat and inflammation, such as Korean barley tea or oolong tea. This is because the tea polyphenols in oolong tea can adsorb oil and expel it from the body, and it also contains lipase that can break down fats. Therefore, oolong tea is said to have the ability to dissolve fat.

Late summer and early autumn are also peak periods for melanin deposition, and spots on women's faces are one of the most troubling annoyances after a vacation. Both green tea and oolong tea have antioxidant properties and have a certain effect on whitening the skin.
