"Can allergies cause one's body temperature to rise?"

ZocdocAnswersCan allergies cause one's body temperature to rise?


Can allergies raise your body temperature? My teenage son has severe seasonal allergies ever since we moved to a new city, and this week he started seemingly running a fever. Is it possible that this is just the allergies? If he has a real fever, I definitely want to see to it.


Questions about fevers in a teenager are best answered by a pediatrician. There are many different causes of fevers. However, seasonal allergies typically do not cause fevers. The symptoms of allergies--runny nose, watery eyes, cough, nasal congestion--can also be caused by viral respiratory infections. It is possible for someone who appears to be suffering from a environmental allergies to actually have a viral upper respiratory infection. Viral upper respiratory infections typically resolve on their own and do not require any specific treatment other than supportive care. However, if a fever persists or if it is accompanied by any additional symptoms that do not clear after a few days, it is best to consult a physician who can perform a more detailed history and physical exam to make sure that there are not any other underlying medical issues which should be addressed. Of note, when following a fever it can often be helpful to keep a log of actual temperatures. This can make it easier for a physician to get a sense of how long and how high a patient's fevers have been. A true fever in an otherwise healthy person is considered to be a temperature over 100.5.
