Asthma triggers will be different for each person, and it is important that you keep track of your asthma triggers. The most common asthma triggers are allergies, irritants in the air, respiratory illness, exercise, weather, strong emotions, and medicines.
Allergies can trigger asthma if you inhale something that you are allergic to. It is best to avoid your allergies to avoid an asthma episode.
Respiratory illnesses including cold and flu are the most common asthma trigger in young children.
An exercise that makes it harder to breathe can affect asthma, especially when done in cold air. With proper treatment, it is not necessary to limit physical exercise.
When the weather is dry and cold or even just a sudden change, you will be more at risk for an asthma episode.
When your emotions are high, your breathing also changes and may cause wheezing or other symptoms in someone with asthma.
Beta-blockers and NSAIDs (if you are sensitive to them) can make asthma hard to control.
