Wildfire Smoke Air Quality Concerns: Tips for Protecting Your Health Indoors and Outdoors
Smoke from the devastating wildfires in Canada has spread to parts of the US and Europe, raising concerns about air quality. The Environmental Protection Agency (EPA) has issued warnings about "very unhealthy" air quality in the Midwest, Northeast, and Great Lakes regions. The EPA's Air Quality Index (AQI) categorizes air quality levels, with lower numbers indicating better air quality. An AQI below 50 is considered healthy, while levels above 150 are hazardous for everyone. In some areas of the Upper Midwest, the AQI reached around 160.
Individuals with asthma, lung disease, or chronic obstructive pulmonary disease are considered sensitive groups and are at higher risk from poor air quality. Dr. Sanjay Sethi from the University of Buffalo's medical school advised those with heart or lung problems to take precautions, such as avoiding outdoor activities or wearing an N95 mask. Even if the smoke is not visible, it can still pose health risks when inhaled.
The EPA and PurpleAir provide real-time air quality data to help people monitor the situation. Purchasing an indoor air quality monitor is recommended by experts to track indoor air quality levels. While short outdoor exposure may not have long-term effects for most people, wearing an N95 mask can help filter out harmful particles. If symptoms like wheezing or shortness of breath occur, it is advised to seek better air quality indoors.
To improve indoor air quality, experts suggest closing windows, using air conditioning with indoor air circulation, and sealing cracks that allow outside air to enter. Installing a MERV 13 filter in the air conditioner can also help filter out pollutants. Running an air purifier in the room where most activities take place can further improve indoor air quality. Taking these precautions can help mitigate the effects of poor air quality caused by the wildfires.
