The principle of covering the quilt to reduce fever is to use a lot of sweating to take away the heat from the body surface to achieve the effect of reducing body temperature. But clinically this is considered an unscientific method of reducing fever, which is not conducive to skin heat dissipation and may not play a role in reducing fever. And if you cover the quilt when you have a high fever, it is easy to sweat a lot after the deficiency, febrile convulsions and other situations. In addition, children with fever should not use this method. Because of the weak thermoregulatory mechanism of young children, the tighter the wrap, the faster the body temperature rises, which is very damaging to the body and prone to dangerous symptoms such as convulsions, convulsions and even shock. Patients should take the correct treatment after fever. If an adult has a fever with a temperature lower than 38.5℃ and a good mental condition, there is no need to take antipyretic drugs, and an appropriately elevated body temperature can improve the patient’s immunity and help the body defend itself against invading pathogens. But when the body temperature is higher than 38.5 ℃, you can try the following methods to cool down: 1, wet compress cooling, that is, a wet towel on the forehead, often replaced; 2, alcohol bath, alcohol concentration of 25%-50% is appropriate; 3, drink a lot of water, water can not only meet the needs of the body’s high metabolism, but also in the body surface sweating or excretion to take away a lot of heat, to help the body cool down; more increase nutrition, three meals Food varieties should be varied, and a light diet is sufficient.
