What are allergies?

Allergy symptoms occur your body’s immune system overreacts to something harmless typically known as an allergen.

Whenever an allergen is breathed in or comes into contact with the skin, your immune system attacks the substance by releasing chemicals such as histamine. Those affected by this may experience allergy symptoms such as sneezing, runny nose, stuffy nose, watery eyes, itchy skin or swelling related to allergy.

What are the different types of allergens?

Dust mites allergies

Dust mites are tiny creatures that are too small to be seen with the naked eye. They reside in fibre-filled surfaces such as mattresses, pillows, linen, carpets and other areas where the conditions are warm, dark and humid. An allergic reaction is triggered by inhalation of the mites’ shed skins and their waste.

Pet allergies

Pet allergies are relatively common and are often triggered by pet dander from animals such as dogs and cats. People with pet allergies have sensitive immune systems that react to harmless proteins found in dander, pet saliva or urine. Contrary to popular belief, pet hair itself is not an allergen, but it may collect dander. Unfortunately for animal lovers, avoiding exposure to the problem animal is the best way to avoid allergy symptoms

Mould allergies

Mould is commonly found both indoors and outside, and may be found in damp, poorly ventilated areas. For people who have a mould allergy, this allergen can trigger symptoms such as sneezing, coughing and a blocked or runny nose. One of the best treatments for mould allergy sufferers, is to avoid contact with mould spores and safe guard your home by managing conditions where mould could grow. Kitchens, bathrooms and laundries are the most common areas of the house that mould grows because of condensation and a lack of airflow. One of the best ways to discourage mould from growing is to increase ventilation in the problem area, therefore open as many doors and windows as possible.

Pollen allergies

Pollens are one of the most common causes of allergies. Many people are allergic to pollen produced by trees, grasses, weeds and flowers. This type of allergic reaction is known as hayfever. Symptons can include sneezing, runny nose, stuffy nose, watery eyes, itchy skin or swelling.
