Physical activity not only helps improve mood, increase energy levels, and decrease depression and anxiety, but could it be the most transformative thing you can do for brain health? After feeling the need to add more physical activity in her own life, Dr. Wendy Suzuki, dean of the College of Arts & Science at New York University, became interested in how powerful exercise could be for people with all levels of cognition. We explore the science behind her findings and how her personal experience inspires her to help us make our brains “fat and fluffy,” to stay as cognitively healthy for as long as we can.
