Dear MEL Topic Readers, 
How to minimise the amount of polluted air you inhale while exercising
Regular outdoor exercise helps you strengthen your body, refresh your mind, and improve daily well-being. When we jog or ride a bike, we breathe faster and more deeply to inhale more air. But how healthy is exercising along a busy street or in a heavily polluted city like Delhi? Invisible micro-particles like PM 2.5 released from traffic can penetrate into our lungs, body, and brain. You are also exposed to other pollutants, such as nitrogen dioxide, sulphur dioxide, ammonia, carbon monoxide, and even ground-level ozone, which are linked to respiratory disease,  cardiovascular disease, diabetes, cognitive function, and even reproductive impacts. Should you then wear a facemask while running, as you did during the pandemic, or stop exercising outdoors at all? There are other ways to reduce exposure to polluted air in a busy place.
Read the article and learn how to mitigate the impact of polluted air when you exercise outdoors in a busy city.
