Babies should not be exposed to fan air during fever.
During fever, babies tend to have higher body temperature and sweat more, and their pores are in an open state. Blowing a fan on them may worsen their fever symptoms. If the weather is hot, you can place the fan far away from the baby and ensure the indoor air is well ventilated to help cool down the baby, without blowing directly at them. During the fever period, babies must be monitored for temperature regularly to avoid febrile convulsion. If the outside air is cool, babies should not be exposed to fan air at all, as it can easily cause cold and worsen the fever. This is because cold exposure can easily lead to respiratory infections, such as colds or diarrhea due to stomach exposure, which can further exacerbate fever symptoms. Some children sweat more severely during fever, and their pores are open. If they are severely exposed to cold fan air, their fever symptoms will worsen significantly. Therefore, it is best not to expose babies to fan air during fever. However, if the outdoor temperature is particularly high, you can place the fan further away to promote indoor air circulation and lower skin temperature, but never blow directly at the baby as it can easily cause cold.
In addition, during fever, it is important to monitor the baby's temperature regularly to ensure it stays below 38.5°C to prevent the occurrence of febrile convulsion.
