The correct way to reduce fever with alcohol is to dilute the alcohol first and then wipe it with clean gauze. The first thing you need to do is to dilute the alcohol, the concentration should not be too high, about 25% to 30%, specifically 25 milliliters of alcohol to 100 milliliters of water. Then use clean gauze to wipe the armpits, groin, neck sides, popliteal fossa and other parts rich in blood vessels, a rub five to ten minutes. If the body temperature has not dropped in an hour, you can wipe again, and you can wipe about five or six times a day. If the temperature drops, there is no need for another rub. If there is sweating after the alcohol wipe, you need to replenish water in time, such as drinking more hot water, so as not to lose too much water caused by the drop in body temperature and cause defecation. Pay attention to the body when the symptoms of fever, we must promptly seek medical treatment, do not delay the condition.
