Allergy

An allergy of any kind is caused when your immune system being hypersensitive to substances in the environment, despite these substances not being harmful at all for the majority of people and thus not regarded as a general health risk. The best example of this would be the pollen scattered in air by plants and flowers as they bloom in springtime. For a person with seasonal allergies, or ‘hayfever’ as it’s commonly referred to, inhaling the pollen will cause them to have an allergic reaction. Atopic dermatitis, allergic asthma and anaphylaxis are further examples among many others.

Certain foods, insect bites and medications may also cause a severe allergic reaction depending on a person’s physiological reactions. Allergies can be both due to genetic and environmental factors, and dust allergies are an example of one allergy that’s both common and an example of both factors contributing to cause an allergic reaction.

A brief detail of the workings of an allergic reaction is as follows; the body mistakes a substance as harmful, and in response to it the immunoglobin E antibodies (IgE) of the body’s immune system then bind to the allergen and proceed to trigger the release of inflammatory chemicals called histamines that cause you to experience the allergic symptoms.
