Wildfire smoke can lead to 'Unhealthy for Sensitive Groups' air quality conditions, posing risks to individuals with asthma, COPD, heart disease, and other chronic conditions. Pregnant individuals, children, and older adults are particularly vulnerable. Symptoms may include respiratory irritation, difficulty breathing, and exacerbation of pre-existing health issues. The agency emphasizes the importance of monitoring AQI levels and taking precautions to minimize exposure during periods of poor air quality.
