How air pollution impacts our brains – Harvard

The air we breathe has a direct impact on our brain. Mounting evidence links air pollution exposure to increased risk for cognitive decline and neurodegenerative conditions, including Alzheimer’s and Parkinson’s. Poor air quality — both indoors and outdoors — also profoundly impacts our mental health, increasing risk for anxiety and depression. With the World Health Organization estimating that 99% of the global population is exposed to unhealthy levels of air pollutants, what can be done to improve air quality and brain health? Our expert panel will break down the latest findings and provide recommendations on policy changes for cleaner air.
