Allergies point to the exaggerated reaction as posed by the immune system as a response to any physical contact with the substances that seem foreign to the body. The reaction is labeled as exaggerated simply because the body itself deems these substances as harmless. At the same time, those who are non-allergic have non-responsive bodies. The reaction turns in when the body realizes that there are certain foreign substances that it gets in contact with and automatically a part of the immune system is activated.
Allergens and their Nature
The allergens are those that produce the allergy. Some known allergens include the dust mite, pollens, foods, dander, and molds, among others. Simply put, the allergens are those foreign substances which when it gets in contact with the body can cause the allergic reaction. However, not all individuals exude the exaggerated reaction. There are those who don't have the allergy on any of the above mentioned allergens.
The term allergic also goes by the name "atopic". It means that your immune system gets turned on as a response to the foreign substances that gets near your body. You develop that allergic reaction when your body inappropriately reacts to the allergens. Hence, you are called allergic or atopic if you are too prone to the allergy.
