Usually babies with fever can blow the fan appropriately, but care should be taken to avoid blowing the fan directly at the baby and not too much wind to avoid aggravating the condition. If the indoor temperature is too high when your baby has a fever, you can open the windows for ventilation. If the outdoor temperature is high, you can turn on the fan or air conditioner to lower the indoor temperature, and place the baby in a position where the wind cannot blow. When your baby has a fever, you can first reduce your baby’s clothing and use physical cooling methods. For example, warm water baths, warm wet towels on the forehead and appropriate more warm water for the child can help speed up the baby’s sweating and make the baby’s body temperature recover, avoiding fever for too long to cause the baby fluid disorders or brain cell damage and other situations. In addition, if the baby’s fever is caused by high ambient temperature or dehydration, it can usually be effectively relieved after physical cooling. If your baby’s temperature does not decrease after physical cooling, or if your baby’s temperature continues to rise, you should seek medical attention to determine if the fever is caused by an infectious disease. Avoid using fever-reducing drugs on your own, but use antipyretic drugs such as ibuprofen suspension under the guidance of a doctor to lower the temperature, and actively look for the cause of your baby’s fever and treat it.
