Asthma Triggers

Triggers can be different for every child. Some common triggers are:

• pets
• dust mites
• pollen
• mould
• air pollution
• second hand smoke
  

Pets

• It is a common myth that children are allergic to a pet’s fur. They are in fact allergic to the animal protein in saliva (spit) and wee, and their dander (dandruff)
• If your child's symptoms improve when they are not around pets you may decide to rehome your pets
• Do not allow pets in the area where your child sleeps
• If you think animals are triggering your child's asthma speak to your GP or asthma nurse

House dust mites

• Declutter your home as much as possible so there are less areas for dust to gather
• Dust with a damp cloth regularly
• Vacuum all soft furnishings
• Avoid the use of fans
• Open the windows daily
• Wash your child’s bedding at least once a week at 60 degrees
• Avoid bunk beds if possible. If this is unavoidable and your child has asthma they should sleep on the top bunk (they need to be over 6 to sleep on the top bunk)
• Get allergy covers for bedding if possible
• Reduce the number of soft toys
• Put soft toys in the freezer once a month for 6 hours to kill dust mites
• If you are planning to redecorate hard floors are better than carpets

Exercise and weather

• Regular exercise improves asthma
• Make sure they drink enough during exercise and have regular breaks
• If cold weather is a trigger ensure they wrap up warm. Cover their mouth and nose with a scarf
• Most importantly make sure they have their yearly flu vaccine
• If warm weather is a trigger it may be due to the pollen or pollution level. Make sure you check the weather forecast and take precautions such as closing your windows
• Avoid hanging your washing out when the pollen count is high
• Avoid letting your child play out in the midday sun
