There are substances or events that can cause someone’s asthma to flare-up (a flare-up is typically indicated by difficulty breathing) – tobacco smoke and e-cigarette aerosol are just two of those triggers. Asthma triggers include (1):
- Outdoor allergens – pollen, trees, and weeds
- Indoor allergens – pet dander, dust mites, and mold
- Certain medications and food additives
- Irritants in the air – smoke, chemical fumes, and strong odors
- Illnesses – colds, flu, etc.
- Events – wildfires and other smokey or heavily polluted environments
- Other triggers – stress, excitement, exercise, exposure to cold air, and sudden temperature changes
Avoiding triggers is one way to successfully manage asthma, proper use of asthma medication is another way.
