4. Asthma

Asthma is a chronic condition that causes difficulty breathing. During an asthma attack, three things can happen.

  1. The muscles around the airways can tighten, making them narrow so that air cannot flow through as easily.
  2. The lining of the airways can swell, making them even narrower, so it's hard for air to pass.
  3. The body may also create more mucus, which is thick and clogs up the airways even more.

Allergies can trigger asthma attacks, but so can stress, exercise, and weather.
