Common types of triggers

  • Inhaled allergens: house dust mite, pollen, pet dander, mould
  • Respiratory infections: cough and wheezing often get worse after a cold
  • Environmental irritants: cold air, smoke, cooking fumes, perfume and renovation smells
  • Exercise and emotional changes: intense exercise, stress and anxiety
  • Other: some medicines, gastro-oesophageal reflux, obesity and irregular daily routines

How to find the pattern

Record the time, place and surroundings when symptoms happen, for example whether you were in the bedroom, whether you had just cleaned, or whether you had contact with a pet. If the same situation comes up again and again, that factor deserves more attention. If needed, tell your doctor about it, and let the doctor decide whether any tests are needed.

Ways to reduce triggers

Wash bedding regularly, clean the home with wet methods, avoid smoke and irritating smells, spend less time outdoors during pollen season and take protective measures, and rest and see a doctor early after a cold. When the air is very cold, wearing a mask outdoors can reduce irritation.
