Your Child's Asthma: Staying Away From Triggers

Triggers are things that make your child's asthma worse. Helping your child stay away from triggers helps control their asthma. Thinking about the things you need to do to help your child stay away from triggers can be overwhelming. Start by working to control the ones that affect your child the most.

Irritants affect all people with asthma.

Smoke is an irritant that can trigger asthma. To protect your child:

• If you smoke or vape, try to quit. This may be the single best thing you can do to help control your child's asthma. Talk to your doctor if you need help quitting. Or contact the American Lung Association at www.lung.org to learn about quit programs and support groups. These can improve your chances of quitting for good.
• Encourage anyone who smokes or vapes in your household to quit.
• Keep your child away from smoke and the aerosol mist from vaping. Do not smoke or vape around your child or in your home, and avoid being around others who are smoking or vaping.
• Keep your child away from incense and smoke from fireplaces.

A cold or the flu can trigger asthma symptoms. To stay away from cold and flu germs:

• Have your child wash their hands often with plain soap and water. (Use an alcohol-based cleanser when you don't have access to water.)
• Keep your child up-to-date on their vaccines. Talk to their doctor about which vaccines are right for your child. This may include the pertussis, COVID-19, influenza, pneumonia and respiratory syncytial virus (RSV) vaccines.

Scents and chemicals can trigger asthma. To reduce these triggers:

• Use pump sprays instead of aerosols.
• Switch to unscented soap, lotion, toilet paper, and cleaning products.
• Don't use air fresheners or perfume.
• If you have a gas stove, use the exhaust fan when the stove is on. Make sure pilot lights are adjusted correctly. (Your utility company can help with this.)

Some types of weather can trigger asthma. Wind spreads pollen. Heat traps air pollution. Cold air can be a trigger all by itself. The best way to prevent weather from triggering asthma is to make sure your child takes their long-term controller medicine. If cold air is a trigger, wearing a scarf over the nose and mouth when outside on cold days may help.

In children with asthma, allergies can trigger flare-ups. The following are some common allergens.

Dust mites are tiny bugs that live in home dust. Dust mites do not bite, but they can cause allergies. Cleaning or removing things that trap dust helps to control them. Start with your child's bedroom:

• Wash all bedding and stuffed animals weekly in hot water at 130°F (54.4°C).
• Vacuum every week. Using a vacuum with a HEPA (high efficiency particulate air) filter is best.
• Put allergen-proof covers over pillows and mattresses.

Furry or feathered animals are common sources of allergens. If your child is allergic, keep these animals away from your child. If you have a furry or feathered pet, try the following:

• Keep the pet out of your child's bedroom. Bathe the pet weekly if possible.
• Be sure that your child has no down (feather) pillows or bedding.
• You may have to find the pet a new home. This can be sad, but it is the best option for your child's health.

Mold thrives in damp places. To reduce mold:

• Fix water leaks.
• Use a dehumidifier to help keep air drier (30% to 50% humidity is ideal).

Pollen from grasses, trees, and weeds can cause allergies.

• If you have an air conditioner, use it during seasons when a lot of pollen is in the air. Change or clean the filters regularly. This lets you keep windows closed, so less pollen gets in.
• Make sure your child bathes and changes clothes after playing outside.
