Sudden shortness of breath, wheezing, and non-stop coughing when a little dust or cold weather hits are a problem that bothers many people today. Scientifically, this is called allergic asthma. This is because when allergens enter the small air passages (bronchioles) in our lungs, they swell and shrink. Here are the 5 main reasons behind allergic asthma:
Dust and mites in the air: The most important villain that aggravates allergic asthma is dust in homes and offices. Dust mites, which cannot be seen with the naked eye, grow on mattresses, pillows, sofas, and carpets. When these reach the lungs, the immune system overreacts and causes shortness of breath.
Molds & Pet Dander: Mold spores that grow on damp walls and bathrooms can cause asthma to worsen when they enter the lungs through the air. In addition, pet hair, saliva, and dead skin cells (dander) from cats and dogs can also cause rapid inflammation in the airways.
Pollen & Strong Odors: In certain climates, breathing in pollen from plants and flowers can trigger asthma attacks. Perfumes, room fresheners, mosquito repellent fumes, and paint fumes can also cause rapid airway constriction.
Genetics & IgE: Children are more likely to develop asthma if their parents have a family history of asthma, eczema (skin allergies), or chronic sneezing (allergic rhinitis). When their bodies have allergies, the immune cells produce a large amount of the antibody IgE (Immunoglobulin E), which causes severe swelling in the lungs.
Weather changes and cold foods: Sudden cold and humidity in the air can make the airways more sensitive. Direct inhalation of extremely cold air, eating cold water, ice cream, and cold foods in the refrigerator can cause asthma to worsen in some people.
Things to do at home to prevent allergic asthma:
Always keep the bedroom clean: Wash bedsheets and pillowcases in warm water once a week and dry them in the sun. Avoid carpets and thick window blinds in the room as much as possible.
Wear a mask: Always wear an N95 mask when going to dusty areas or cleaning your home. Stay away from people who smoke.
Inhale steam: To loosen the mucus in your chest and open your airways, practice simple steam inhalation.
