Tea is a good drink for heatstroke prevention and cooling. Li Shizhen's Compendium of Materia Medica contains:

"Tea is bitter and cold, ... the best way to reduce fire, fire is all diseases, and fire is clear. ..... Warm drinks will cause fire to drop due to cold, while hot drinks will raise a cool Tieguanyin or a scalding Tieguanyin through internal heat, which will cool your body and mind, promote fluid production and quench your thirst.

This is because tea soup contains tea polyphenols, sugars, amino acids, pectin, vitamins and so on. It reacts chemically with saliva in the mouth to moisten the mouth, so it can play the role of promoting fluid production and quenching thirst.

At the same time, due to the caffeine in Tieguanyin, a lot of energy is released from the pores of human skin, thus achieving the effect of removing fire. If the computer family drinks tea, it will also prevent radiation.
