Some people may find that exercise triggers asthma symptoms.
Both genetics and environment play a role in the development of asthma, but scientists still do not know the exact causes. That said, they have identified a number of triggers for asthma symptoms.

Asthma triggers can vary from person to person and may include:

  • respiratory infections, including the cold or flu
  • irritants in the air
  • air pollution
  • tobacco smoke
  • exercise
  • cold air
  • medications, including beta-blockers and nonsteroidal anti-inflammatory drugs
  • stress
  • food and drink preservatives
  • allergens, including dust, dander, and pollen
  • acid reflux
