Not every type of childhood asthma looks the same. In this post, our pediatric team breaks down exercise-induced bronchoconstriction (EIB) — a form of asthma that's often overlooked because many kids seem perfectly healthy until they're active.
What Is EIB?
Exercise-induced bronchoconstriction is a temporary narrowing of the airways that happens during or shortly after physical activity. Because symptoms show up mainly with exertion, a child can look completely fine at rest — which is exactly why it's easy to miss.
How It Differs From Typical Asthma
With more familiar forms of asthma, symptoms can be triggered by many things — allergens, colds, weather, or irritants — and may occur throughout the day. With EIB, the main trigger is exercise itself. A child who breathes easily at home may start coughing or wheezing a few minutes into running or sports.
Symptoms to Watch For
During or after physical activity, look for:
- Wheezing
- Chest tightness
- Shortness of breath
- Unusual tiredness or avoiding activities they used to enjoy
Helping Your Child Stay Active
The goal isn't to keep kids on the sidelines — it's to help them play and compete comfortably. That often includes a proper warm-up, awareness of triggers, and a plan from your child's provider, which may involve using an inhaler before activity.
If your child seems short of breath, coughs, or wheezes during sports or play, don't ignore it. A pediatric provider can evaluate their breathing and help them stay active, confident, and breathing easier.
