This is an important message from the U.S. Department of Health and Human Services.
Wildfire smoke's greatest health threat is to those with heart and lung conditions, older adults and children. Listen for advice from local authorities and limit your exposure to any smoke, including low levels. Keep your indoor air as clean as possible. If you have asthma or other lung conditions, follow your respiratory management plan. See a doctor if you have a hard time breathing or if your normal symptoms worsen.
