Hospitals are typically subsidized by the government, for-profit or nonprofit health agencies, health insurance providers, or charities, such as through direct charitable donations. Depending on the funding source, hospitals can be classified into one of three groups.

The following are the types of hospitals:

• • Allergens: Inhaled allergens like pollen, dust mites, pet dander, and mold spores can trigger asthma symptoms.
  • Irritants: Smoke (including secondhand smoke), strong chemical fumes, and air pollution can irritate the airways and cause an asthma attack.
  • Respiratory infections: The common cold or flu can worsen asthma symptoms.
  • Exercise-induced asthma (EIA): Cold air, dry air, or strenuous exercise can trigger asthma symptoms in some people.
  • Medications: Certain medications, such as aspirin or beta-blockers (except those specifically prescribed for asthma), can trigger asthma in some individuals.
  • Emotional stress: Strong emotions like anxiety or anger can worsen asthma symptoms for some people.
