What the orange AQI means
The orange air quality index (AQI) category is considered unhealthy for sensitive groups of people.
Sensitive groups include children, the elderly and people with respiratory conditions such as asthma. The MPCA warns that pollution can worsen heart and lung disease, as well as cardiovascular and respiratory diseases.
According to officials, the air travels long distances and mixes with harmful smoke, which can cause symptoms such as chest pain, shortness of breath, wheezing, coughing and fatigue.
People are encouraged to limit outdoor physical activities and avoid local sources of pollution such as busy roads and wood fires.
