Asthma Triggers
Childhood asthma in particular can be triggered by almost all of the same things that trigger allergies, such as the following:
- Sensitivity to allergens in the air, such as dust, cockroach waste, animal dander, indoor and outdoor mold, pollens
- Respiratory infections
- Air pollutants, such as smoke from tobacco or a fireplace, aerosols, perfumes, fresh newsprint, diesel particles, sulfur dioxide, elevated ozone levels, and fumes from paint, cleaning products, and gas stoves
- Changes in the weather, especially in temperature (particularly cold) and humidity
Other triggers include:
- Behaviors that affect breathing (exercising, laughing, crying, yelling)
- Stress
