NHL games were suspended in early June 2024 due to hazardous air quality caused by widespread wildfire smoke. Significant wildfires in Canada, particularly in British Columbia, Alberta, and Saskatchewan, have been emitting large amounts of smoke, which has been carried by prevailing winds across parts of the United States. This smoke has led to air quality indices reaching “unhealthy” and even “hazardous” levels in various regions, including major cities such as New York【7†source】【8†source】.
The decision to suspend NHL games was made to protect the health and safety of players, staff, and fans. The smoke from these wildfires contains fine particulate matter (PM2.5), which can penetrate deep into the lungs and even enter the bloodstream, exacerbating respiratory and cardiovascular conditions. Health officials have been advising people, especially those in vulnerable groups, to stay indoors and avoid strenuous activities outside【8†source】.
In addition to the NHL games, other outdoor events and activities have been curtailed or moved indoors as a precautionary measure. Residents in affected areas have been encouraged to use air purifiers and ensure their indoor air quality is as clean as possible by keeping windows and doors closed and using high-quality air filters【7†source】.
These wildfire conditions and their resulting impacts highlight the broader challenges posed by climate change, which is expected to increase the frequency and severity of such events in the future【7†source】【8†source】.
