Replacing hot water with hot tea can indeed increase water intake and supplement essential vitamins and trace elements. But it is not good for patients with fever. Not only does it fail to reduce the fever, it can also cause body temperature to rise. Why?
First of all, we need to know the chemical components in tea, which contains tannic acid, theophylline, and caffeine. Tannic acid has an astringent effect and inhibits perspiration. After drinking it, patients with fever will cause the body to lose heat. Theophylline and caffeine have excitatory effects, which will make the central nervous center of the human body stay in a state of excitement for a long time, thereby accelerating the heartbeat, promoting blood circulation, and causing blood pressure to rise. The heartbeat and blood pressure of patients with fever are inherently high. The effect is nothing less than worse.
In addition, if a variety of chemical substances contained in the tea chemically react with the anti-fever medicine taken, the results may weaken the efficacy of the anti-fever medicine in the mild case, and may produce toxic substances in the severe case, and the consequences will be unimaginable.
