Physical cooling is generally wiped every 30 minutes for about 3-5 minutes each time. Physical cooling mainly involves stimulating local skin with warm water and low alcohol to dilate blood vessels and increase the skin’s ability to dissipate heat. For the elderly and children who are weak, body wiping with warm water is recommended for fever. Before each wipe, the body temperature should be measured again. Above 38.5 degrees, medication such as fever suppositories or oral antipyretics should be used. When the body temperature drops below 38 degrees Celsius, it usually does not cause other complications such as febrile convulsions, so you can drink more water and observe more. Fever is an immune response of the body, and most of them are infectious fevers caused by inflammatory stimuli, which require active treatment of the primary disease if necessary. During the fever period, care should be strengthened, pay attention to warmth after physical cooling, avoid getting cold, and do not use excessive force when wiping to prevent abrasion of the skin, leading to breakage or local infection.
