Nasal Allergies and Colds

Cold viruses are the typical cause of common cold which involved the infection of the upper respiratory tract such as nose, nasal passages and throat. The common cause of nasal allergies is however, due to allergic reactions in reaction to allergens such as dust mite, mold or pet dander which exist in the air of the inhabiting surroundings. Breathe in such type of allergen can directly result in a series of allergic reactions like nose congestion, sneezing, runny nose which are exactly the same as when people are having cold.

This is because the immune system of the body reacts the same way when it detects the presence of allergens and the attack of viruses which both will stimulate the cold or nasal allergy symptoms. Both of the symptoms are so similar that you hardly can distinguish them without ambiguity. However, this is not the case if you want to differentiate the causes of nasal allergies and colds.
