Asthma Triggers: Managing Your "Sparks"
Key Information
- Sensitive Airways: If you have asthma, your airways are sensitive. Triggers act like “sparks” that can set off symptoms.
- Everyone is Different: Your triggers may not be the same as someone else’s.
- The Key to Control: Good asthma management means knowing your personal triggers and having a plan to manage them.
Common Triggers and Solutions
- 1. Colds and Flu
- The Trigger: Respiratory infections are a common cause of flare-ups.
- The Solution: Vaccination is your best protection. Get your free annual flu vaccine and any COVID-19 boosters you are eligible for.
- 2. Cold Weather
- The Trigger: Cold, dry air can provoke symptoms.
- The Solution: Wrap a scarf loosely over your nose and mouth outdoors to warm the air before it reaches your lungs.
- 3. Allergies
- The Trigger: Pollen, dust mites, and pet dander are common allergens.
- Pollen: Check daily forecasts during spring and summer.
- Dust: Use allergen-proof bedding and damp-dust regularly to reduce airborne particles.
Identifying Your Sparks
Because everyone’s triggers are different, keeping a symptom diary can help.
- Record: Note when symptoms occur and what you were doing or where you were.
- Spot Patterns: Over time, patterns may appear (for example, coughing when visiting someone with a cat, or wheezing when running in cold weather).
