Content: Outdoor air pollution Emissions from factories, cars, buses, lawn mowers, leaf blowers, and snow blowers can all trigger an asthma attack. Try to avoid exposure to these sources whenever possible. It’s also a good idea to check air quality measurements related to pollution in your area, such as ozone and small particles, and to stay inside as much as possible when they’re elevated. Certain foods and food additives While almost any food can cause an allergic reaction, a few additives (like sulfites and other preservatives) are widely believed to cause adverse reactions in some people. Acid reflux can also trigger an asthma attack in some people, so any food that aggravates this condition may also be responsible for symptoms. Respiratory infections These include influenza (flu), the common cold, respiratory syncytial virus (RSV), and sinus infections. Strong emotional states Negative emotions like stress, anxiety, depression, or fear can cause an attack, often by causing hyperventilation (heavy, fast breathing). Certain medications While different people have different triggers, common culprits include aspirin and other nonsteroidal anti-inflammatory drugs ( NSAIDs) such as ibuprofen ( Advil, Motrin) and naproxen ( Aleve ).
