Can iced black tea help to relieve thirst and reduce heat?

　　Iced black tea can usually help to stimulate saliva production and relieve summer heat; moderate consumption is recommended.

　　Iced black tea contains a large amount of water, which can effectively replenish fluids lost by the body and alleviate thirst. It also contains components such as tea polyphenols; moderate consumption can help quench thirst, refresh the mind, and provide a certain cooling and heat-relieving effect through its refreshing taste. Compared with carbonated drinks or fruit juices that are very high in sugar, choosing low-sugar or sugar-free iced black tea as a summer beverage can reduce calorie intake and be more beneficial to health.

　　Excessive consumption of iced black tea may irritate the gastric mucosa and cause gastrointestinal discomfort, so it should be consumed in moderation. Additionally, the caffeine in iced black tea may affect sleep, so it is recommended not to consume excessive amounts in the evening. Individuals who are allergic or sensitive to caffeine, as well as pregnant and lactating women, should consume iced black tea cautiously to avoid adverse effects on health.

　　In daily life, in addition to iced black tea, other healthy cooling beverages such as mung bean soup and chrysanthemum tea can also be chosen to help stimulate saliva production and relieve summer heat.
