Allergies occur when the body is tricked into thinking that harmless particles are dangerous invaders.The immune system tries to get rid of these allergens by sneezing, flushing them out with tears or mucus, or removing them with nose rubbing. It strives to stop them from entering into the lungs by constricting the airways. These are all normal reactions to toxins and viruses. Allergies cannot be completely prevented.Only the known symptoms can be avoided by avoiding known allergens. An important thing to be done is to find the allergy triggers. All the details surrounding the allergy flare-ups should be noted.
