Infants can use physical cooling with alcohol, but warm water wipes are more recommended because infants’ skin is more delicate and weaker, easily allergic to alcohol, prone to local cold and flu, and aggravating clinical symptoms. Only when the weather is hot, other physical cooling methods did not achieve significant results, can be used urgently and occasionally. When using alcohol for physical cooling, choose 35% alcohol, the concentration should not be too high. It is usually rubbed on superficial vascular areas, such as the neck, armpits, groin and popliteal fossa. Because the above parts are rich in subcutaneous blood vessels, after repeatedly rubbing the bath with alcohol, evaporation and cooling can take away more heat, and the effect of physical cooling will be better.
