What triggers allergies?

A number of different allergens trigger allergies in people, with some of the most common including pollen, dust, mould and pets.

The Pollen Index measures the potential for pollen to trigger allergic reactions in susceptible people. Pollen levels in the atmosphere will be highest on hot days and on days where a dry wind is blowing. Additionally, light rain overnight or during the early morning will also cause high pollen levels. These are the days when you will experience the telltale symptoms of a runny nose, watery eyes, itchy skin and nasal congestion.

  • Clean surfaces regularly, to avoid the accumulation of dust
  • Avoid feather and down pillows
  • Don't hang sheets or clothing outside to dry on days of high pollen count
  • Avoid high pile carpets, as they offer places for dust and allergens to hide
  • Keep your pet away from bedrooms and off all furniture
  • Wash your pet weekly
  • Try to stay indoors on days of high pollen count
  • Avoid mowing lawns or wear a mask if it is unavoidable
