1 Physical cooling Parents should immediately take physical cooling for their children when they find that their children have a fever, and repeatedly wipe the large blood vessels on the child's body surface through warm water and alcohol to dilate the blood vessels and promote heat dissipation. You can give your child a warm bath immediately, or after diluting alcohol with warm water, wipe your child's armpits, elbow sockets, thigh roots, etc., and take away the heat by the evaporation of alcohol to achieve the purpose of reducing fever. After half an hour, give the child weight and temperature.

2 If the body temperature is still higher than 39℃ when the physical cooling effect of antipyretics is not good, you can take antipyretic stickers and antipyretics to cool down. When using antipyretic drugs, we must pay attention to the dosage and contraindications. Families can choose over-the-counter antipyretics to take orally, and be careful not to eat them frequently or excessively. After taking the medicine, you will often sweat a lot, and pay attention to replenish water to avoid dehydration.

3 Add a lot of water. When the child has a fever of 39 degrees, let the child lie down and rest quietly and drink more boiled water. On the one hand, it can promote metabolism in the body and excrete toxins; On the other hand, a large amount of water supplement can induce diuresis, and can also take away some heat to help reduce fever.

4 Reduce clothing or quilt When a child has a fever of 39 degrees, it needs to emit heat to quickly reduce the fever. Therefore, the bedroom should be ventilated by opening the window, unbuttoning the neck, reducing clothes or quilts when necessary to promote heat dissipation, and not covering the sweat. If you find a child sweating, you should wipe the sweat for the child in time. Children can drink some salty boiled water, which has supplemented the salt lost in sweat.
