Asthma Triggers and Allergies

Asthma symptoms often don’t appear without cause – they’re triggered. With World Allergy Awareness Week upon us (29 June – 5 July), it is a timely opportunity to highlight the most common triggers that contribute to asthma symptoms and flare-ups.

Identifying and minimising exposure to your specific triggers is a critical part of asthma management, alongside having an up-to-date Asthma Action Plan.

Pet Dander

Hair and skin flakes from cats, dogs, and other animals can worsen asthma symptoms.

Pollen

Tree, grass, and weed pollen are frequent culprits, especially during peak allergy seasons.

Colds & Flu

Respiratory viruses like the common cold, flu, and COVID-19 can inflame airways and trigger asthma attacks.

Cold Air

Breathing in cold or dry air may provoke coughing, wheezing, or shortness of breath.

Smoke & Fumes

Exposure to cigarette smoke, exhaust, strong cleaning sprays, or scented products can irritate the lungs.

Dust

Household dust, especially in carpets, bedding, and upholstery, is a common indoor trigger.

Temperature Changes

Sudden shifts in temperature can be a shock to the respiratory system and lead to symptoms.
