Environmental Allergy

Allergy is a hypersensitivity disorder of the immune system. Most common environmental allergies occur to airborne allergens, such as dust mite, pollen, pet dander, mould spore, particulate matter or formaldehyde (VOC). Some individuals may respond to allergens which activate the production of IgE, leading to type I hypersensitivity. This will result in sniffling, sneezing, coughing, or itching or even an extreme inflammatory response.

Asthma and Allergy

Some main signs of allergy are itchiness, sneezing, inflamed or infected eczema, watering/reddening eyes, runny nose and clogging in the lungs. Allergens are tiny and light perfect for taking wing in the ducts and open air of spaces around your house. Indoor allergens like formaldehyde, dust mite, mould, particles or even volatile chemicals from conventional cleaners can accumulate in your air conditioners, curtains, mattresses, sofas and carpets . Allergens produced by house dust mites are among the most common triggers of asthma. Therefore, deep clean your home regularly is essential.

IgE and Asthma

Immunoglobulin E, or IgE, is a kind of antibody that plays an important role in the development of allergic asthma. Increased levels of IgE may result when you are exposed to allergens, such as dust mite, pollen, pet dander, mould spore, particulate matter or formaldehyde. Your body releases IgE, which then binds with several types of cells like basophils, lymphocytes & mast cells. This can then stimulate your immune system, cause your airways to become narrow and inflamed, and make your asthma symptoms worse.
