Fever is a manifestation of the baby’s use of his immunity to fight against the virus. In the process of fighting fever, the child’s immunity is also improved. For this reason, the fever-reducing myths that parents often use in daily life are deciphered one by one. Myth No. 1: Covering sweat to reduce fever “Take some medicine, cover for a while, sweat out the fever”. Zhong Yingjie said that it is not scientific to reduce fever by covering up the sweat. “When a child has a fever, wearing too much will affect the body heat dissipation so that the body temperature rises, even in a hyperthermic state, sweating increases, while the body’s metabolism is hyperactive, oxygen consumption increases, most likely leading to the body multi-organ, multi-system involvement.” When a child has a fever, undress the child slightly to allow adequate heat dissipation and ensure indoor air flow, but pay attention to the baby’s hands and feet to keep them warm. Myth 2: Fever does not bath rub cold water bath child fever, some parents for its rub cold water bath to reduce fever, fever children take a warm bath is more conducive to heat dissipation. If it is inconvenient to take a bath, it is also possible to take a bath with warm water. After taking a bath with warm water or taking a bath, you should quickly dry your whole body and change into dry clothes. Myth 3: Use antipyretics as soon as you get a fever Generally speaking, physical cooling is recommended for children with a body temperature below 38.5°C. If the temperature exceeds 38.5°C, antipyretics should be given along with physical cooling. There are many different kinds of antipyretics, but parents are advised to use the children’s form of antipyretics, especially for infants, which can be used in the form of drops. The interval between taking antipyretics must be 4-6 hours. Misconception four: children with high fever to the doctor before dealing with clinical, many parents worry that giving their children fever-reducing drugs will affect the doctor’s accurate judgment of the condition, or do not know what drugs to use for the child, so there is no active cooling of the child, must see a doctor; or the child have high fever, parents do not deal with at home directly to the hospital. This approach is also incorrect. If the child has a fever of 38.5 ℃ or more, you should actively cool the child, especially if the baby has a high fever, such as a long time high fever and do not deal with it, easy to cause febrile convulsions, fainting and other phenomena occur.
