Exercise When Pollution is Low

Exercise Outdoors on Days When Pollution Levels Are Low

A recent article noted that before exercising outdoors one should check levels of ozone and particulates. During winter inversions or at other times of high particulate pollution it is best to exercise in the mountains or inside (health club or walking at a shopping mall)… Susceptible individuals and those with multiple cardiac risk factors should limit prolonged outdoor activity when PM2.5 is between 20–35.

When PM2.5 is over 35, there should be no prolonged outdoor exertion by anyone. Exercising outdoors is sometimes enjoyable, but checking pollution levels is wise. I exercise indoors on a treadmill and exercise bike with a Health Guardian purifying the air I breathe.
