When rubbing the body with wine, it can reduce fever, which is also a method of physical cooling, but it is not routinely recommended in clinical practice. After alcohol is rubbed on the body, it can have the same evaporative effect as water, which takes away heat after evaporation, thus achieving a physical cooling effect. However, the reason why it is not recommended is that water does not cause much of a problem on the human skin, even if it is absorbed. And if you use alcohol, it will be absorbed through the skin for the body. In the fever, the microcirculation under the epidermis is very rich, alcohol is very easy through this pathway, into the human body, so rubbing the body with alcohol, may lead to alcohol poisoning. In physical cooling, it is not recommended to use alcohol to wipe the whole body, but only warm water close to the skin temperature, to wipe the whole body.
