Drinking hot tea can accelerate the contraction of stomach wall more than drinking herbal tea, and the effective components of clearing heat and relieving summer heat can play a role faster. Tea nowadays is more suitable for fermentation. Nutrients will not be destroyed and oxidized, especially in summer. If you want to put it in the next day, you'd better soak it in a pot and put it in the shade or refrigerator. It is reported that a clinical research center in Britain does not believe the theory that "hot tea is the best way to relieve summer heat". Representatives from all fields of life, not Aryans, were invited to participate in the verification. Let them choose all kinds of delicious drinks, drink them happily, and then test your skin temperature.

I don't know if you have had this experience. In summer, we took a cold bath and felt very good. We feel very happy, but after a while, we will sweat and be very hot. We want to soak in the cold swimming pool all day. The more you wash, the more tired you get; I remember when I was a child, every summer, my parents and teachers told me that cold drinks would make me feel good, but that was only a short-term effect, because the mechanism of cold drinks was to replenish calories at low temperature, and I didn't mention that a cold drink could compensate for limited calories. After drinking cold drinks, cold stimulates the sensitive neurons of cold receptors in human peripheral cold receptors.

Although it is very hot when drinking hot tea, the heat after drinking will increase with sweat, and the heat will be discharged to the depths of the human body, thus reaching the heat dissipation paper, which is extremely cold and lasts for a long time. Drinking hot tea is colder than drinking cold drinks. It is best to drink hot tea in summer. The content of theophylline in strong tea is higher than that in green tea, which will lead to excessive mental excitement, abnormal function of nervous system and excessive gastric acid secretion, which will have extremely unfavorable consequences for patients with gastric ulcer and duodenal ulcer, so green tea is better than strong tea.

You will feel cold after drinking cold drinks, but this is only a temporary effect, because the antipyretic mechanism of cold drinks is to compensate the heat with low temperature, not to mention the limited amount of heat that cold drinks can compensate. After drinking cold drinks, cold stimulates the central cold-sensitive neurons of human peripheral receptors. Because hot tea has a good diuretic effect, it can absorb a lot of heat and lung substances in the body and lower the body temperature. Theophylline in hot tea plays an important role in controlling the regulation of hypothalamic temperature center. In addition, it also has a heat dissipation effect on volatile aromatic substances.
