Can a head fever be a symptom of allergies?
The simple answer is: Really no, but sometimes it can.
Fever is a symptom of infection. In nature, the body tries to take advantage of a pathogenic invader’s optimal living environment by causing itself to heat up. Many bacterial and viral organisms that cause sickness in humans have evolved over time to be suited to human body temperatures around 98 degrees.
Like humans, if these pathogenic invaders get too hot, they will die. And that’s what the immune system is trying to do. It’s a common misconception that the infection causes the fever–it doesn’t.
So do allergies cause a fever? No, definitely not. However, allergies can sometimes make it easier for pathogens to invade.
When there is excessive mucus production in your sinuses and the digestive tract, your body is more vulnerable to infection because pathogens have learned to hide and grow in the mucus that our body produces. This lets them spread more easily through the body.
Fever is Not Caused by Allergies
When you’re allergic to something you have come in contact with, your immune system produces chemicals like histamine, which promotes inflammation in the body. This results in mucus production, sneezing, coughing, and more. Some symptoms of allergies may make it easier for you to get sick.
This is one of the reasons why treating allergies effectively is so important.
It’s also important to note that you can have allergy symptoms alongside the symptoms of an infection. In fact, this is quite common. It would be easy to connect the dots and assume that your allergy symptoms made you sick.
Therefore, if you have a fever, your allergies are not what you need to be worrying about. If you think you have something more severe than a common cold, you should contact your doctor, drink some pure water and get some rest.
I recommend that you don’t take fever-reducing medicines unless your doctor advises you to. Sometimes this can prolong an infection.
