You may think you know all there is to know about preventing asthma attacks. Just take a hit on a bronchodilator inhaler, right? Wrong.

Preventing asthma attacksthe sudden onset of wheezing, coughing, and shortness of breath due to exposure to dust, pet dander, cold air, pollution, exhaust, or secondhand smoketakes a comprehensive long-term strategy.
While there is no cure for asthma, asthma attacks can be prevented or reduced by taking medication daily (usually called controller or maintenance medications), avoiding asthma triggers, and modifying ones environment (such as minimizing dust and other allergens).
