Final answer:
Major triggers of asthma include environmental factors and allergens like animal dander, pollen, stress or anxiety, peanuts (if allergic), tobacco smoke, and respiratory infections, which may lead to the exacerbation of symptoms in individuals with genetic predisposition to asthma.
Step-by-step explanation:
Asthma is a chronic inflammatory disease that affects the airways in the lungs. Major triggers of asthma include:
- Animal dander
- Bee stings are not a common asthma trigger unless the individual has a specific allergy to bee venom.
- Ear infections are not a direct trigger, but respiratory infections are.
- Peanuts can trigger asthma if the person has a food allergy.
- Pneumonia can potentially exacerbate asthma symptoms.
- Pollen
- Stress or anxiety
- Tobacco smoke
Environmental factors and allergens, such as those listed above, can lead to asthma attacks, particularly in individuals with a genetic predisposition.
