Wildfire smoke poses serious health risks, particularly due to the small particles it contains. Southern California is currently experiencing a windblown dust and ash advisory, covering large parts of Los Angeles and Riverside, as wildfires continue to burn. The advisory is expected to last until Wednesday evening.
Health officials are urging residents to protect themselves by staying indoors when possible, wearing protective equipment, and improving indoor air quality. Wildfire smoke contains particulate matter (PM), tiny particles that can be inhaled and absorbed into the bloodstream, leading to inflammation in the lungs and affecting other organs such as the heart and brain.
Vulnerable groups—such as children, older adults, pregnant individuals, and those with preexisting health conditions—are at a higher risk. Exposure to PM can cause coughing, wheezing, difficulty breathing, and long-term health impacts, potentially lasting weeks or even years. Medical experts recommend checking air quality regularly, using masks, and seeking medical help if symptoms worsen, such as chest pain or respiratory distress.
To minimize exposure indoors, it’s advised to keep windows and doors closed and use high-efficiency air filters (MERV 13 or higher). Portable air cleaners can also help improve air quality. If going outside is necessary, wearing an N95 or P100 mask is recommended.
Public health officials stress the importance of taking action to protect vulnerable populations and monitoring air quality to mitigate health risks during wildfire events.
