Indoor allergens can be trickier to detect, but there are several things you can do in your home to reduce exposure, improve air quality, and treat your symptoms. While these measures differ slightly based on the specific allergen, there are a few things that apply to all.
The irritating chemicals in cigarette smoke cause symptoms similar to allergic rhinitis like coughing, congestion, wheezing, and headaches. People with allergic rhinitis often have intensified allergy symptoms when they come in contact with tobacco smoke.
There is evidence that people can and do outgrow allergies, particularly specific food allergies. However, more commonly adults will develop a new allergy in response to increased exposure to different environmental allergens.
The short answer is — no — allergies do not directly cause a fever. A high temperature is a sign that your body is fighting a bacterial or viral infection. Sometimes allergies can lead to a sinus infection, and a fever is a symptom of a sinus infection, so allergies can indirectly cause a fever.
When your body is hypersensitive to certain stimuli, its negative response can be classified into four distinct types of allergic reaction: anaphylactic, cytotoxic, immunocomplex, or cell-mediated. Each one is triggered in different ways and can manifest differently in each person.
