Wildfires in California have led to the evacuation of tens of thousands in Los Angeles, with air quality reaching "hazardous" levels.
The EPA warns that wildfire smoke contains a complex mixture of pollutants that can have severe health effects even after short-term exposure.
Air quality advisories highlight that small particles in the smoke can lead to respiratory issues, headaches, and other health problems.
Sensitive populations, including children, the elderly, and those with pre-existing health conditions, are at greater risk and are advised to stay indoors.
Experts recommend using N95 masks and air purifiers to mitigate exposure, and suggest avoiding any indoor activities that could worsen air quality.
