Exercise-induced asthma can occur in people of any age and activity level, even in people who don't normally have asthma symptoms. But, certain people are more likely to be diagnosed with the condition than are others. Factors that increase your risk include:

  • Already having asthma triggered by other things
  • Having poorly controlled asthma
  • Having hay fever or other allergies
  • Having a blood relative, such as a parent or sibling, with asthma
  • Exposure to air pollution or pollen
  • Smoking or exposure to secondhand smoke
  • Exposure to chemical triggers, such as chlorine in swimming pools or gases used to resurface ice for skating
  • Participating in winter sports, such as figure skating, ice hockey or cross-country skiing
  • Participating in sports that make you breathe harder and faster, such as running or playing soccer
  • Being a child — children are generally more active than adults
