There are many methods of physical cooling in clinical practice. The most commonly used is to choose warm water, or to wipe areas such as the palms, soles, neck, and chest with alcohol. It should be noted that infants should not use alcohol. You can also drink more ginger sugar water or scallion water, or use cool towels, ice packs, etc., to apply cold compresses to the forehead. These can achieve the effect of physically reducing fever. Be sure to drink plenty of water and measure the temperature again two hours later. If the fever does not ease, it is necessary to use medication in a timely manner.
