1. Outdoor urban exercise

Getting outside for some fresh air and exercise seems like one of the healthiest habits you can develop for your brain and body. But here’s the thing…

If you live in an urban area where pollution levels are high, that outdoor exercise routine might be doing more harm than good.

When you exercise near high-traffic areas, you inhale particulate matter from car exhaust, which Dr. Swart says can cause neuroinflammation and cognitive decline. Inhaling polluted air also suppress BDNF, a brain protein that improves brain plasticity, memory, and cognition.

So, rather than go for a roadside run or ride, head to the gym. Or at the very least, reroute your exercise somewhere green like a park or forest preserve.
