It's hot and a headache. Is it useful to drink some herbal tea?

Summer is very hot, especially when people feel thirsty after sweating. People want to drink a large cup of herbal tea to quench their thirst and relieve fever. In fact, drinking herbal tea in summer is very particular. If the method is wrong, it will be harmful to health. Many people think that herbal tea is to soak tea leaves and let them cool naturally for a long time. Some people make tea in the morning and drink it in the afternoon, some people make tea in the afternoon and drink it in the evening, and some people drink it the day before and the day after, which is called overnight tea. From a scientific point of view, it is better not to drink this herbal tea. Because herbal tea soaked for a long time has at least three shortcomings: First, tea polyphenols, amino acids, vitamins, aromatic substances, pectin, sugar and other components in tea will reduce the nutrition in tea due to automatic oxidation. Second, the reduction of effective components in tea will inevitably lead to the decline of color, fragrance and quality of tea, which will make the original tea with mellow color and fragrance become gloomy and lose the taste value of tea. Third, tea leaves will be contaminated by microorganisms in the surrounding environment if they are kept for a long time. So how do you drink refreshing and hygienic herbal tea? There are two ways: first, prepare some cold boiled water in advance, then make a cup of slightly strong hot tea, and then add cold boiled water to the hot strong tea to make herbal tea. Secondly, after the tea leaves are soaked, putting the tea set directly into cold water for cooling, or putting it in the freezer for a period of time will also turn hot tea into herbal tea. Drinking such herbal tea in summer is good for your health. In short, it is good to drink herbal tea, but we should pay attention to the ways and means.
