Wildfire smoke can be harmful to everyone’s health even at low concentrations. Everyone can take action to reduce their exposure to wildfire smoke.

People with lung disease (such as asthma) or heart disease, older adults, children, pregnant people, and people who work outdoors are at higher risk of experiencing health effects caused by wildfire smoke. Speak with your health care provider about developing a management plan for wildfire smoke events and maintaining a supply of necessary medications at home and always carrying these medications with you during wildfire season.
