Low fever (i.e., body temperature within 37.3~38.5℃): such cases can be promptly taken to physical cooling (such as cold wet compresses), generally without special treatment. However, if the body temperature continues to not drop, or even other uncomfortable symptoms, you should seek medical treatment. 2. Moderate or above fever (i.e. body temperature ≥38.5℃): This kind of situation may cause high fever convulsions, so physical (such as cold wet compresses) or medication (such as acetaminophen, etc.) should be taken in time to cool down the temperature to prevent further damage to the body.
