The wildfire smoke contains fine particulate matter (PM2.5), which can penetrate deep into the lungs and enter the bloodstream, posing significant health risks. Sensitive groups, including children, older adults, pregnant individuals, and those with respiratory or heart conditions, are particularly vulnerable. At 'Unhealthy' AQI levels, everyone may experience adverse health effects, and prolonged outdoor activities should be limited. The situation could escalate to 'Very Unhealthy' (201-300) or 'Hazardous' (301-500) levels if conditions worsen, requiring stricter precautions.
