Wendy Suzuki, a Professor of Neural Science and Psychology at NYU and author of "Good Anxiety," explores the evolutionary role of anxiety. She explains how anxiety isn't just a negative feeling but can be harnessed into six beneficial "superpowers." By understanding the brain's response to anxiety, including the amygdala's activation and the prefrontal cortex's shutdown, she discusses techniques like cognitive flexibility to turn anxiety into productivity and empathy, transforming discomfort into positive outcomes.
