History of Allergy Awareness Week
Allergies are very much real and affect more people than we may think. It might be minute as a minor rash or as severe as a complete immune system shutdown, but either way, allergies are an essential health topic and should be treated as such. If you’ve heard the saying ‘One man’s food is another man’s poison,’ then you may already understand the concept of allergies. There are several things we encounter daily without reaction that could stir up allergies in other people. It could be the water we drink, the food we eat, or even the stuffed animals we have lying around. It boils down to the difference in our D.N.A. and genetic makeup.
Simply put, allergies are conditions triggered by a sensitivity of the immune system to substances in the environment that would ordinarily be considered harmless. Often, people suffering from allergic conditions do not realize it until they experience their first reaction. These reactions come with symptoms like rashes, red eyes, shortness of breath, and even swelling. Allergies develop due to genetic makeup (hereditary factors) and environmental conditions. Allergic reactions are caused by the binding of the immune system’s antibodies to the allergen and then to a receptor, which triggers the release of inflammatory chemicals.
The term ‘allergy’ appeared in the 1900s and was coined from the Greek words ‘allos’ (other) and ‘ergon’ (work). Since then, several classifications and diagnostic methods have been applied to distinguish various allergies. Allergies are common among over 50% of the worldwide population living with an allergy.
Allergy UK, a British charity, established Allergy Awareness Week. It focuses on raising awareness for children and adults living with allergies, raising funds, and offering resources to support allergy victims.
