Can the Weather Affect My Child's Asthma?


Can the Weather Affect My Child's Asthma?

Yes. Weather conditions can bring on asthma symptoms. Some kids' asthma symptoms get worse at certain times of the year. For others, a severe storm or sudden weather change can trigger a flare-up.

Cold, dry air is a common asthma trigger and can cause bad flare-ups. That's especially true for people who play winter sports and have exercise-induced asthma.

Hot, humid air also can be a problem. In some places, heat and sunlight combine with pollutants to create ground-level ozone. This kind of ozone can be a strong asthma trigger.

Wet weather and windy weather can cause problems too. Wet weather encourages mold growth, and wind can blow mold and pollen through the air.

If you think weather plays a role in your child's asthma, keep a diary of asthma symptoms and possible triggers and discuss them with your doctor. If pollen, mold, or other allergens make asthma symptoms worse, ask about allergy testing.

Your child's written asthma action plan should list weather triggers and ways to manage them, including any seasonal changes in medicine.
