When a child has a fever, he or she should be covered with a small amount of blankets, not more, but it is better to cover less because it is easy to catch a cold without blankets. During a fever, the body temperature is often shifted upward, possibly due to a viral or bacterial infection, and after the body temperature is shifted upward, heat dissipation decreases and heat production increases, so the symptoms of fever appear. If you cover more blankets at this time, the heat dissipation will be even worse, but it will aggravate the increase of body temperature and the symptoms of fever, so you should cover a small amount of blankets during the fever. When the fever temperature is high, for example, over 38.5°C, you also need to take oral antipyretics for treatment to avoid inducing febrile convulsions, which can cause irreversible damage to the child’s brain cells or brain function. It is recommended to use ibuprofen suspension or acetaminophen suspension to reduce fever, the effect is still relatively good.
