Lung health is negatively affected during wildfire season by increased smoke pollution. Wearing N95 masks protects lung health in the short-term. The purpose of our study is to assess whether wearing of N95 facemasks on days with moderate to high air pollution in people who go outside to golf on a regular basis (two or more times per week) for two months during the wildfire season projects lung health.
Wildfire smoke negatively affects lung health. Across North American, millions of people are exposed to wildfire smoke most summers. The purpose of our study is to determine whether people who golf regularly (two or more times per week) can use N95 masks to protect their lungs from wildfire smoke. Forty regular golfers will be randomized to receive N95 masks or not to receive masks. All participants will be told to follow guidelines for outdoor activity based on Air Quality Health Index readings. Those randomized to wear N95 facemasks will be asked to wear these on days they golf where Air Quality Health Index indicates moderate risk or higher. The main outcome is compliance with wearing the N95 mask. Secondary outcomes include changes in lung function, blood pressure, and respiratory symptoms over two months.
