>What's in forest fire smoke?
Forest fire smoke is made up of a mixture of gases and very small particles that are produced when wood and other organic matter burn. These small particles and gases can be harmful to your health.
What are short-term health risks?
Your body will try to protect itself against smoke by making more tears and mucous. This can cause runny noses, scratchy throat, irritated sinuses and headaches. You may also develop a cough.
A number of health effects are associated with wildfire smoke, including asthma and chronic obstructive pulmonary disease (COPD) exacerbation, bronchitis, pneumonia, and cardiovascular outcomes.
