Frequent sneezing, a runny or blocked nose, itchy eyes, and throat irritation are common signs of allergies. While many people blame only dust and dirt, several other everyday triggers can also cause allergic reactions. Here are six common allergy triggers:
- Pollen
Pollen from trees, grasses, and weeds is one of the most common causes of seasonal allergies. During flowering seasons, pollen particles spread through the air and can trigger sneezing, nasal congestion, and itchy eyes. - Pet Dander
It’s not pet fur itself but tiny flakes of skin (dander), saliva, and urine proteins from cats and dogs that can trigger allergies. These allergens can remain in the air and on furniture for long periods. - Dust Mites
Dust mites are microscopic organisms that thrive in mattresses, pillows, carpets, and upholstered furniture. Their waste particles are a major indoor allergy trigger, especially in humid environments. - Mould (Mold) Spores
Mould grows in damp areas such as bathrooms, kitchens, basements, and poorly ventilated rooms. Breathing in mould spores can cause sneezing, nasal congestion, coughing, and irritation. - Strong Fragrances and Air Pollution
Perfumes, room fresheners, cigarette smoke, vehicle exhaust, and other air pollutants can irritate the nose and airways. Although they may not always cause a true allergy, they can trigger allergy-like symptoms in sensitive people. - Certain Foods
Foods such as milk, eggs, peanuts, tree nuts, shellfish, soy, and wheat can trigger allergic reactions in some individuals. Symptoms may include itching, swelling, hives, breathing difficulty, or digestive problems.
When to see a doctor:
If your symptoms last for more than two weeks, keep returning, interfere with daily life, or are accompanied by wheezing or difficulty breathing, consult a healthcare professional. Identifying the specific trigger through allergy testing can help you manage symptoms more effectively.
