Wood smoke can affect everyone, but the populations known to be at greater risk include: children, teenagers, older adults, people with lung disease -- including asthma and COPD, people with heart disease and people with limited access to medical care. Research indicates that obesity or diabetes may also increase risk. New or expectant mothers may also want to take precautions to protect the health of their babies, because some studies indicate they may be at increased risk. Do your part to improve air quality.
