Exposure to wildfire smoke affects people’s health. Exposure to particulate matter irritates the eyes, nose, and throat, and increases the risk of heart disease, asthma, and other health problems.

Particle pollution from wildfire smoke can cause a range of symptoms and health effects.

• Symptoms similar to allergies
  • Red eyes
  • Respiratory symptoms such as coughing, wheezing, difficulty breathing, excess phlegm

• More severe symptoms (with extended exposure)
  • Bronchitis
  • Reduced lung function
  • Worsening asthma
  • Increased rates visits to emergency room
  • Increased rates of hospital admissions
  • Cardiovascular effects leading to heart failure, stroke

There is growing scientific evidence to link cardiovascular and respiratory effects to wildfire smoke exposure.  Exposure to particle pollution can exacerbate existing diseases, create pulmonary inflammation, and cause reductions in lung function.

NOTE:

• During a wildfire emergency, if a person’s symptoms are minor, medical care is likely not necessary. However, if someone is experiencing chest pain or trouble breathing, they should contact a medical provider.
