Fever in children is often associated with changes in the external environment, viral infections and complications such as bronchitis, and the way to reduce fever needs to be determined by the degree of fever. Usually, when a child’s body temperature is below 38.5°C, non-pharmacological treatment should be chosen as follows: 1. Warm and wet compresses: Warm towels or antipyretic patches are placed on the forehead, armpits, groin and other large-vessel areas of the child to achieve cooling purposes. 2, warm water bath: parents can use a warm, wet towel to scrub the child’s body or take a warm bath, thereby promoting the body surface heat dissipation. It is recommended to focus on the armpits, elbow sockets, groin and other places when wiping. 3, drink more water: whether or not to use drugs, should let children drink more water, reluctant to drink water children can also try lighter juice, sweating children can drink oral rehydration salt. 4.Chinese medicine: apply the technique of “clearing Tianhe water, retreating the six internal organs and clearing the lung meridian” to reduce fever, generally pushing once a day for three days. If the child’s age is more than 10 years old, you can also massage the back acupuncture points such as the large vertebrae point, lung Yu, stomach Yu, wind Chi to reduce fever. If a child has a fever of more than 38.5°C, he or she should seek medical attention to determine the cause and treat the cause. It is also necessary to apply drugs such as ibuprofen or acetaminophen to reduce fever under the guidance of a doctor. Ibuprofen should only be used for children over 6 months of age and should be avoided in children with frequent vomiting and dehydration to avoid kidney damage, while acetaminophen can be used for children over 3 months of age.
