Factors that Contribute to Asthma Attacks

There are many different types of factors that can trigger an asthma attack. Allergens, viral infections, sinusitis, irritants such as strong odors, chalk dust, tobacco smoke, temperature changes, exercise, gastroesophageal reflux, chemical irritants, certain medications (e.g. medications for high blood pressure and glaucoma) and emotional anxiety all can contribute to frequency and severity of asthma attacks.
