Whether a child has a fever with a hot face and not a hot forehead is determined by the measurement of a thermometer. And allergy symptoms also tend to cause redness and heat in the face. If your baby has a hot face and forehead, you can’t rely on the symptoms alone to determine whether you have a fever or not, and you should take the thermometer measurement as the basis. Take the mercury thermometer to measure the temperature of the armpit as an example, if the temperature of the armpit at this time is greater than 37.3 ℃, it can be diagnosed as fever. If the temperature does not exceed 38.5 degrees, physical cooling can be given, such as using a warm towel to wipe the armpits, forehead, groin and other parts of the fever. If the temperature exceeds 38.5 degrees, ibuprofen or acetaminophen-based antipyretic medication will need to be given to reduce the fever under a doctor’s supervision. If the body temperature is normal, but only the face is red and hot, may be caused by allergies, it is recommended to consult a doctor in time, find allergens and try to avoid contact, if necessary, can be oral cetirizine oral solution, etc., which is conducive to the elimination of allergic reactions. There are many reasons why children’s faces are hot and foreheads are not hot, it is recommended to consult a doctor for examination and treatment after clarifying the cause of the disease.
