Climate Adaptation – Particulate Matter and Health
Increased temperatures as a result of climate change stifle air circulation and create drought conditions that increase the likelihood of wildfires. Wildfires produce particulate matter that can cause serious health problems.
An extensive body of scientific evidence indicates that breathing in fine particles over the course of hours to days (short-term exposure) and months to years (long-term exposure) can cause serious public health effects that include premature death and adverse cardiovascular effects.
Long-term and short-term exposure to fine particles can cause:
- Premature death, especially due to cardiovascular effects
- Non-fatal cardiovascular events, such as heart attacks and strokes, as well as increased hospital admissions and emergency department visits for congestive heart failure and reduced blood supply to the heart
- Respiratory effects such as: asthma attacks; coughing, wheezing, and shortness of breath; reduced lung function and development
Scientific evidence also indicates that breathing in larger (“course”) sizes of particulate matter may also have public health consequences. Short-term exposure may be linked to:
- Premature death
- Hospital admissions and emergency department visits for heart- and lung-related diseases
At-Risk Populations
People most at risk from particle pollution include people with diseases that affect the heart or lung (including asthma), older adults, children, and people of lower socioeconomic status. Research indicates that pregnant women, newborns, and people with certain health conditions, such as obesity or diabetes, also may be at increased risk of particle-related health effects.
